Can some one solve this and show their work plssss
Answer:
For WXYZ to be a parallelogram, both pairs of opposite sides must be parallel.
So, we have 7m + 4 = 9m and 5y + 13 - (2n - 1) = 6y - 8 - (n + 6).
Solving the first equation, we get m = 2.
Solving the second equation, we get y - n = 4.
Thus, for WXYZ to be a parallelogram, m = 2 and y - n = 4, so option B is correct.

The simple interest on a certain sum at 5% per annum for 3 years and 4years differ by rupees 82 find the sum
The principal sum is Rs. 1640 if the difference in simple interest between 3 years and 4 years is Rs. 82 at a rate of 5% per annum.
Let x be the principal sum. According to the problem, the difference in simple interest between 3 years and 4 years is Rs. 82. This means that the interest earned in the fourth year is Rs. 82 more than the interest earned in the third year.
Using the formula for simple interest, we can calculate the interest earned in each year:
Simple interest for 3 years = (x * 5% * 3) = 0.15x
Simple interest for 4 years = (x * 5% * 4) = 0.2x
The difference between the two is:
0.2x - 0.15x = 0.05x
We are given that this difference is equal to Rs. 82, so:
0.05x = 82
Solving for x, we get:
x = 82 / 0.05 = 1640
Therefore, the principal sum is Rs. 1640.

Value of angle x is 41 degree.
Define straight lineA straight line is a one-dimensional geometric object that extends infinitely in both directions. It can be defined as the shortest path between two points in a plane, and it has a constant slope (i.e., rate of change) between any two points on the line.
The standard equation for a straight line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line intersects the y-axis). Another commonly used form is the point-slope form, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line.
Given, total angle=236°
236°=76°+119°+x
x=236°-76°-119°
x=41°
Hence, Value of angle x is 41 degree.

the 4 th term of a geometric sequence is 125, and the 10th term is 125/64. find the 14th term. (assume that the terms of the sequence are positive). show your working
By using the formula of a geometric sequence, the 14th term will be 125/1024
We have, the Fourth term of geometric sequence T_4= 125 and T_10 = 125/64
Let's find the first term and common ratio of the geometric sequence.
Using the formula of the nth term of a geometric sequence, we get,
T_4 = a * r^3 = 125 ....(1)
and,
T_10 = a * r^9 = 125/64 ...(2)
On dividing eq. (2) by eq. (1), we get,
(r^6) = (125/64) / 125 ⇒ 1/64
Taking the sixth root of both sides, we get:
r = (1/64)^(1/6)
r = 1/2
Now that we know the common ratio, we can use the equation for the nth term of a geometric sequence:
T_n = a * r^(n-1)
To find the 14th term, we substitute n=14 and solve:
T_14 = a * (1/2)^(14-1) ⇒ a * (1/2)^13
We don't know the value of a yet, but we can use the fact that the 4th term is 125 to solve for it:
a * r^3 = 125
a * (1/2)^3 = 125
a = 125 * 2^3
a = 1000
Substituting this value for a, we get:
T_14 = 1000 * (1/2)^13
T_14 = 1000 * 1/8192
T_14= 125/1024
Therefore, the 14th term of the geometric sequence is 125/1024.

Answer: Yes Sofia will have enough money
=======================================================
Explanation:
Refer to the drawing below. I've split the hexagon into two pieces. The bottom is a rectangle and the top is a trapezoid.
The area of the rectangle is 16*7 = 112 square meters.
The trapezoid has 16 as one of the parallel sides. The other side is x meters. We'll use the perimeter 54 to determine what x must be
sum of the exterior sides = perimeter
6+7+16+7+6+x = 54
42+x = 54
x = 54-42
x = 12
The top most side is 12 meters. This is the missing side of the trapezoid. The hexagon has a height of 12.66 meters, so the trapezoid's height must be 12.66-7 = 5.66 meters. Refer to the blue segment I marked in the drawing below.
area of the trapezoid = 0.5*height*(base1+base2)
area = 0.5*5.66*(16+12)
area = 79.24 square meters
----------------
Recap so far
area of the rectangle at the bottom = 112 square metersarea of the trapezoid up top = 79.24 square metersThe total area of the entire hexagon is therefore 112+79.24 = 191.24 square meters.
Let's convert that to square decimeters.
Recall that 1 decimeter = 10 centimeters
Multiply both sides by 10
1 decimeter = 10 centimeters
10*(1 decimeter) = 10*(10 centimeters)
10 decimeters = 100 centimeters
10 decimeters = 1 meter
Then,
[tex]191.24 \text{ sq m}= 191.24 \text{ sq m} * \frac{10 \text{ dm}}{1 \text{ m}} * \frac{10 \text{ dm}}{1 \text{ m}}\\\\= \frac{191.24*10*10}{1*1} \text{ sq dm}\\\\= 19124 \text{ sq dm}\\\\[/tex]
The entire lawn is 19124 square decimeters.
----------------
We have one final block of calculations to determine the total price.
x = number of rolls
1 roll covers 90 square decimeters
x rolls cover 90x square decimeters
90x = 19124
x = 19124/90
x = 212.489 approximately
Round up to the nearest integer to get x = 213. It doesn't matter that 212.489 is closer to 212. We round up to clear the hurdle. It means we'll have leftover grass that isn't used (perhaps it could be handy to have some back up grass just in case mistakes are made, and some patches need to be redone).
In short, Sofia needs 213 rolls.
1 roll costs $4.50
213 rolls will cost 213*4.50 = 958.50 dollars.
This is under the $1000 threshold (with 1000-958.50 = 41.50 dollars to spare).
Sofia will have enough money to pay for all of the grass.

what are the dimensions of the soup can of greatest volume that can be made with a 150 square inches of tin
The dimensions of the can of greatest volume that can be made with 150 square inches of tin are a radius of approximately 5.78 inches and a height of approximately 3.85 inches.
What are the dimensions?The dimensions of the soup can of greatest volume that can be made with 150 square inches of tin are given by the formula [tex]V = \pi r^2h[/tex], where V is the volume of the can, r is the radius of the base, and h is the height of the can. We can solve for the radius and height of the can using the given information.
Let the radius of the base be r and the height of the can be h. Then, the surface area of the can is given by the formula [tex]A = 2\pi rh + 2 \pi r^2[/tex]. We are given that the surface area of the can is 150 square inches, so we can write the equation [tex]2 \pi rh + 2 \pi r^2 = 150[/tex]. We need to find the dimensions of the can that maximize its volume, V. To do this, we can use the formula for the derivative of V with respect to r, which is [tex]dV/dr = 2 \pi rh + \pi r^2 dh/dr[/tex].
Setting this equal to zero and solving for h, we get [tex]h = -2r/3[/tex]. Substituting this into the equation for A, we get the equation [tex]2 \pi r(-2r/3) + 2 \pi r^2 = 150[/tex], which simplifies to [tex]-4 \pi r^2/3 + 2 \pi r^2 = 150[/tex]. Solving for r, we get [tex]r = 5.78[/tex] inches. Substituting this into the equation for h, we get [tex]h = -3.85[/tex] inches.
Since we cannot have a negative height, we must discard this value and take the positive value of h, which is approximately 3.85 inches. Therefore, the dimensions of the can of greatest volume that can be made with 150 square inches of tin are a radius of approximately 5.78 inches and a height of approximately 3.85 inches.

What is the probability?The probability that the 3rd card is a heart if the first card was a heart and the second card was a club when three cards are drawn without replacement from an ordinary deck of 52 playing cards.
There are 13 hearts in a deck of 52 cards.
Therefore, P(1st card is a heart) = 13/52 = 1/4
There are 13 clubs in a deck of 52 cards. Since one heart is already drawn in the first card, there are only 51 cards left in the deck.
Therefore, P(2nd card is a club) = 13/51
There are only 12 hearts remaining in the deck since one heart is already drawn in the first card. There are only 50 cards left in the deck since two cards are already drawn.
Therefore, P(3rd card is a heart) = 12/50 = 6/25
The probability that the 3rd card is a heart if the first card was a heart and the second card was a club is:
P(3rd card is a heart | 1st card is a heart and 2nd card is a club) = P(1st card is a heart) × P(2nd card is a club) × P(3rd card is a heart) = (1/4) × (13/51) × (6/25) = 39/5,775 = 0.0152 (rounded to 5 decimal places)

If u dissolve 50 grams of sugar in 30 grams of water what would the sugar concentration be?
The sugar concentration would be approximately 62.5%.
To find the concentration of sugar in the solution, we need to use the formula:
Concentration = Mass of solute ÷ Volume of solutionIn this case, the solute is sugar and the solvent is water. We are given that the mass of sugar is 50 grams and the mass of water is 30 grams. However, we need to convert the mass of water to volume since we need the volume of the entire solution to calculate the concentration.
We can assume that the density of water is 1 g/mL, so the volume of water is 30 mL. The total volume of the solution is therefore 50 mL + 30 mL = 80 mL.
Now we can use the formula to find the concentration of sugar:
Concentration = 50 g ÷ 80 mL ≈ 0.625 g/mLSo the concentration of sugar in the solution is approximately 0.625 grams per milliliter.

5 points on a graph for the equation 2^x+5 +1
I already know the asymptote is 1.
Answer:
When x = 0, y = 2^0 + 6 = 7. So the first point is (0, 7).
When x = 1, y = 2^1 + 6 = 8. So the second point is (1, 8).
When x = 2, y = 2^2 + 6 = 10. So the third point is (2, 10).
When x = -1, y = 2^-1 + 6 = 6.5. So the fourth point is (-1, 6.5).

elise is a project manager in 2016 she earned a monthly salary of £2100
in 2017 she was awarded a 3% increase on her monthly salary
given that in 2017 elise worked 42 hours per week for 45 weeks
work out her average pay per hour for the year
Answer:
Elise's average pay per hour for the year 2017 was £11.88.
Step-by-step explanation:
First, we need to calculate Elise's monthly salary in 2017 after the 3% increase:
3% of £2100 = 0.03 x £2100 = £63
Elise's new monthly salary in 2017 = £2100 + £63 = £2163
Next, we need to calculate her total earnings in 2017:
Total earnings = monthly salary x number of months worked
Elise worked for 45 weeks in 2017, which is approximately 10.4 months:
Total earnings = £2163 x 10.4 = £22,477.20
Finally, we can calculate her average pay per hour for the year:
Total number of hours worked = 42 hours/week x 45 weeks = 1890 hours
Average pay per hour = total earnings / total number of hours worked
Average pay per hour = £22,477.20 / 1890 hours = £11.88 per hour
Answer:
I got $13.73 per hour
Step-by-step explanation:
If you multiply 2100 by 12 months you get $25200 for an annual salary before percent increase.
Then you include the 3% salary increase each month 25200 x .03 = 756 then add the two 25200 + 756 = 25956 OR you can calculate the longer way by doing each individual month, either way it will be the same answer. 2100 x .03 = 63 then 2100 + 63 = 2163 then 2163 x 12 = 25956
Then you divide 25956 by the number of weeks worked in the year. 25956/45 = 576.8
So, each week $576.8 was earned.
Then to get an hourly rate, you divide this by the number of hours worked in each week. 576.8/42 = 13.73
So, the hourly rate is $13.73.

A skater has a mean score of 7. 25 points. An equation to determine the skaters total scores received from eight judges is equals to the x₁ + x₂ + x₃ + x₄ + x₅ + x₆ + x₇ + x₈ = 58.
Mean is called the average of the values and is calculated by dividing the addition of values by the total number of values. It is denoted by [tex]\bar X[/tex]. That is bar above X represents mean of x number of values. Mathematically, Mean = (Sum of all the values/Total number of values).We have in a skating compotion where each skater receives score from eight judges. Now, Mean or average of score points obtained by a skater = 7.25 points. Let the skater's received score from eight judges be equals to x₁,x₂,x₃,x₄,x₅,x₆,x₇, x₈. Total score received by skater = x₁ + x₂ + x₃ + x₄ + x₅ + x₆ + x₇ + x₈ and we have to write the equation to determine the skaters total scores. Now, in this case mean of scores means the sum of scores received by skaters from eight judges divided by eight (judges).

The coordinates of the point P is (-1,2) .
What is translation?
In mathematics, a translation is a geometric transformation that moves every point of a figure or a space by the same amount in a given direction. The amount and direction of the movement can be described using a vector, which is a mathematical object that has both magnitude and direction.
Finding the coordinates of the point P :
The coordinates of point P can be found by subtracting the vector from point Q.
To find the coordinates of point P, we need to subtract the vector [tex]\begin{pmatrix}4\\-3\end{pmatrix}[/tex] from the coordinates of point Q, which are (3, -1).
Subtracting the x-coordinate of the vector from the x-coordinate of point Q gives us:
3 - 4 = -1
Similarly, subtracting the y-coordinate of the vector from the y-coordinate of point Q gives us:
-1 - (-3) = 2

The equation of the circle in standard form is (x-5)² + (y+1)² = 9. The center of the circle is (5,-1) and the radius is 3.
To write the equation of the circle in standard form, we need to complete the square for both x and y terms:
x² - 10x + y² + 8y + 37 = 0
(x² - 10x + 25) + (y² + 8y + 16) + 37 = 25 + 16
(x - 5)² + (y + 4)² = 6²
So the equation of the circle in standard form is (x - 5)² + (y + 4)² = 36.
The center of the circle is (5, -4), and the radius is 6.

...A store pays $261 for a diving board and marks the price up by 45%. What is the amount of the mark-up?
Answer:
If the store marks up the price of the diving board by 45%, the selling price will be 100% + 45% = 145% of the cost price.
Let's calculate the selling price:
Selling price = Cost price + Mark-up
Mark-up = Selling price - Cost price
Mark-up = (145% of cost price) - cost price
Mark-up = 0.45 * cost price
We know that the store paid $261 for the diving board, so:
Mark-up = 0.45 * $261 = $117.45
Therefore, the amount of the mark-up is $117.45.
well, what's 45% of 261?
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{45\% of 261}}{\left( \cfrac{45}{100} \right)261}\implies \text{\LARGE 117.45}[/tex]

help!! i really can't do this pls help me with this inquality question
Explanation:
2n is greater than 20, so 2n > 20. This solves to n > 10 after dividing both sides by 2. That inequality is the same as 10 < n.
5n is less than 60. It leads to 5n < 60. That solves to n < 12 after dividing both sides by 5.
To summarize:
"2n is greater than 20" leads to n > 10, aka 10 < n."5n is less than 60" leads to n < 12Combine 10 < n with n < 12 to write a compound inequality:
10 < n < 12
The value n is between 10 and 12. We exclude each endpoint.
The only possible whole number that works here is n = 11
problem 05.058 - caps removed from sphere knowing that two equal caps have been removed from a wooden sphere of diameter 11.8 in., determine the total surface area of the remaining portion.
The total surface area of the remaining portion is approximately 23.14 in.
To find the total surface area of the remaining portion of a wooden sphere after two equal caps have been removed, use the formula SA = 4πr2. A sphere is symmetrical, and thus, the diameter of the wooden sphere is equal to the diameter of the remaining portion. The radius of the remaining portion is equal to half the diameter of the sphere minus the radius of the cap.
The diameter of the wooden sphere is 11.8 in. As such, the radius of the sphere is 5.9 in. If two equal caps are removed, the diameter of the remaining portion is equal to 11.8 in - 2x R_cap, where R_cap is the radius of the cap. Since the caps are equal, we can simplify the formula to
D = 11.8 - 2R_cap. R_cap is equal to the radius of a circle with area equal to the surface area of one cap. As such, we can use the formula SA = 2πrh + πr2 to find the surface area of the cap. We know the diameter of the sphere is 11.8 in. Thus, the radius of the sphere is 5.9 in. We also know that the height of the cap is 5.9 in. Since the caps are equal, we can use the formula to find the surface area of one cap and multiply by 2 to get the total surface area of both caps.
SA_cap = 2π(5.9 in)(5.9 in) + π(5.9 in)
2SA_cap = 2π(34.84 in2) + π(34.84 in2)
SA_cap = 2π(34.84 in2) + 109.45 in2SA_cap ≈ 219.74 in
Since the surface area of the cap is equal to 219.74 in, we can use the formula to find the radius of the cap.
219.74 in = 2πrh + πr22(219.74 in2)
= 2π(5.9 in)h + π(5.9 in)22(219.74 in2)
= 37.699 in2 + 109.45 in23r2
= 72.533 in2r ≈ 4.545 in
Using the formula D = 11.8 - 2R_cap, we can find the diameter of the remaining portion of the wooden sphere.
D = 11.8 - 2(4.545 in)D ≈ 2.71 in
The radius of the remaining portion of the wooden sphere is equal to 5.9 in - 4.545 in. Thus, the radius of the remaining portion of the sphere is 1.355 in. Finally, we can find the total surface area of the remaining portion of the sphere.
SA = 4πr2SA = 4π(1.355 in)2SA ≈ 23.14 in
Therefore, the total surface area of the remaining portion is approximately 23.14 in.

To solve the question asked, you can say: So the other side of the triangle will be as [tex]A = \sqrt73[/tex].
What precisely is a triangle?A triangle is a closed two-dimensional geometric object consisting of three line segments, called edges, that intersect at three places called vertices. Triangles are distinguished by their sides and angles. A triangle can be equilateral (all sides equal), isosceles, or odd, depending on the sides. Triangles are classified as acute (any angle less than 90 degrees), right (angles equal to 90 degrees), or obtuse (any angle greater than 90 degrees). The area of a triangle can be calculated using the formula A = (1/2)bh. where A is the area, b is the base of the triangle, and h is the height of the triangle.
here in the triangle we have sides that are 3 and 8
we can use
[tex]A^2 = B^2 + C^2\\A^2 = 3^2 + 8^2\\A^2 = 9+64\\A^2 = 73\\A = \sqrt73[/tex]
So the other side of the triangle will be as [tex]A = \sqrt73[/tex].
