Answer:
10.0 lb/wk ---> final solution
Step-by-step explanation:
There are 7 days in a week right? so ----> 1 week = 7 daysNow, just convert days per week into hours so ----> 7 days × 24 hours = 168 hours168 hours converted to ounce are around 160 ounces =, or 159.9 oz to be more precise. (we convert hours to ounces so we can then find out the answer in pounds)Lastly, convert the ounces you got into pounds so ----> 10 lbs per weekYour employer offers a 401(k) plan in which they will match 100% of

Answer:
they will match 5% of 35,000 = $1750

Cheryl had 22 charms. She used C charms to make a bracelet then she went to the store and bought 14 more charms. Now she has 25 charms. How many charms did Cheryl use to make the bracelet
Answer:
She used 11 charms.
Step-by-step explanation:
25-14=11
22-11=11
Answer: She used 11 charms.
Step-by-step explanation:
The equation to find the answer is 22-C+14=25. You would minus 14 from both sides, leaving you with 22-C=11. 22-11=11, so your answer is 11 charms. Hope this helped!

The speed of the boat going with a current is 20 mph. When the boat goes against the current, the speed is 16 mph. Find the speed of the boat in still water and the speed of the current.
Answer:
The speed of the boat in still water is 18 mph.
The speed of the current is 2 mph
Step-by-step explanation:
Let x represent the speed of the boat in still water.
Let y represent the speed of the current.
When the boat goes against the current, the speed is 16 mph. Assuming it traveled against the current while going upstream, its total speed would be (x - y) mph. It means that
x - y = 16 (equation 1)
Going downstream, the boat averages 20 mph. Assuming it traveled with the current, its total speed would be (x + y) mph. It means that
x + y = 20 (equation 2)
Adding both equations, it becomes
2x = 36
x = 36/2
x = 18 mph
Substituting x = 18 into equation 1, it becomes
18 - y = 16
y = 18 - 16
y = 2 mph

In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B. The combined score for all three teams was 983 points. Write an equation to represent this scenario using the variable b to represent Team B's total points. Translate the scenario.
Answer:
(2b - 5) + b + (b + 80) = 983
Step-by-step explanation:
Given that,
Total score of three teams = 983
Since the teams' scores are given in reference to team B's score, let 'b' be the score of team B.
So,
The scores of Team A = (2 * b) - 5
The scores of Team B = b
The scores of Team C = (b + 80)
Thus,
The equation for determining the total points of Team B would be:
(2b - 5) + b + (b + 80) = 983
On solving,
(2b - 5) + b + (b + 80) = 983
⇒ 2b + b + b = 983 + 5 - 80
⇒ 4b = 908
⇒ b = 908 ÷ 4
⇒ b = 227
Team B's score = 227
Team A's score = (2 * 227 - 5)
= 449
Team C's score = 227 + 80
= 307
Total ⇒ 449 + 227 + 307 = 983
Hence proved.

The equation of circle with center (h,k) and radius r units is
(x - h)^2 + (y - k)^2 = r^2
The equation of the circle with center (2,3) and radius 5 cm is

4. Which class(es) appear to have the most consistent scores? Explain your reasoning,
Answer:
1. The shape of the histogram created with MS Excel is approximately bell shaped and approximately evenly spread about the central (largest counts) values
The shape of the box plot created with MS Excel is approximately evenly distributed
2. The appropriate measure of central tendency for a bell shaped histogram is the mean and median, due to the approximately equal distribution about the highest frequency class
3. Part A
The 15 numbers between 1 and 20 generated by a random generator are;
1, 8, 8, 15, 4, 18, 11, 6, 17, 1, 18, 15, 10, 12, 11
The measure of center is the mean = (1+8+8+15+4+18+11+6+17+1+18+15+10+12+11)/15 = 155/15 = 31/3
The measure of spread used is the variance, s² = 32.38
[tex]Where, \,s^2 =\dfrac{\sum \left (x_i-\bar x \right )^{2} }{n - 1}[/tex]
[tex]{\sum \left (x_i-\bar x \right )^{2} }[/tex] = 453.333
n = 15
s² = 453.[tex]\overline 3[/tex]/(15 - 1) = 32.38
Part B
The measure of central tendency are the mean and the median because the size of the data (n = 15), is 75% of the population (N = 20) nd therefore the data is approximately normal and can be represented by the mean and the standard deviation
Step-by-step explanation:

The coach of a lacrosse team bought ice cream cones to celebrate a victory. A single-scoop cone was $3 and a double-scoop cone was $5 The coach bought 15 cones and paid $57. A system of equations describing this situation could be written in the form below where s represents the number of single cones andd represents the number of double cones. What is the sum of A, B, C and E?
Answer:
s=9
d=6
Step-by-step explanation:
s+d=15
3.s+5.d=57
⇒s=9 và d=6
The sum of A, B, C, and E is 23. Let's set up a system of equations based on the given information: s: number of single-scoop cones
d: number of double-scoop cones
1. The coach bought 15 cones in total:
s + d = 15
2. The cost of a single-scoop cone was $3 and the cost of a double-scoop cone was $5, and the total payment was $57:
3s + 5d = 57
Now, let's find the values of s and d by solving the system of equations.
First, we can use the first equation to solve for s in terms of d:
s = 15 - d
Now, substitute this value of s into the second equation:
3(15 - d) + 5d = 57
Now, solve for d:
45 - 3d + 5d = 57
2d = 57 - 45
2d = 12
d = 6
Now that we have the value of d, we can find the value of s using the first equation:
s = 15 - d
s = 15 - 6
s = 9
So, the number of single-scoop cones (s) is 9, and the number of double-scoop cones (d) is 6.
Now, let's find the sum of A, B, C, and E:
A: The number of single-scoop cones (s) is 9.
B: The number of double-scoop cones (d) is 6.
C: The cost of a single-scoop cone is $3.
E: The cost of a double-scoop cone is $5.
A + B + C + E = 9 + 6 + 3 + 5 = 23
So, the sum of A, B, C, and E is 23.

What is the value of X
Answer:

Step-by-step explanation:
since this is an isosceles triangle, this means that the two base angles are equal. therefore, 8y-7=73°, meaning that y = 10° (although we don't really need to know that since you're just supposed to find x).
the angles of a triangle add up to 180°, so we can add all the angles and set them equal to 180° to find x.

Answer:
[tex]x=55[/tex]
Step-by-step explanation:
Corresponding angles of two parallel lines are always equal. The angle on "top" of [tex]2x+6[/tex] corresponds with the angle marked as [tex]x+9[/tex]. Therefore, its measure must also be [tex]x+9[/tex].
Since these two angles form one side of a line which has 180 degrees, we have the following equation:

Combine like terms:
[tex]3x+15=180[/tex]

how long will it take the minute hand of a clock to turn through 240°
Answer:
40 minutes
Step-by-step explanation:
360/60 = 6 degrees per minute
240/6 = 40 minutes
Answer:
40 minutes / 2400 seconds
Step-by-step explanation:
One full rotation of a circle is 360°
One hour (full rotation of minute hand) is 60 minutes
360° = 60min
Divide both sides by 60
6° = 1min
So every 6° is 1 minute.
240° / 6° = (x minutes) / 1 minute
x = 40 minutes
Alternatively:
1 hour = 60 minutes
1 minute = 60 seconds
So, 1 hour = 60×60 = 3600 seconds
3600 seconds / 360° = 10 sec/°
==> This means that every 1° is 10 seconds on the minute hand
240° × 10 sec/° = 2400 sec
(Divide by 60 for 40 minutes)
What are the steps i need to do (along with the answer) to 9^x = sqrt of 729?
Answer:
last option is correct 3/2
Answer:
x = 3/2
Step-by-step explanation:
9^x = 729 ^ 1/2
We need to get the bases the same
729 = 9^3
9^x = 9^3 ^ 1/2
We know that a^b^c = a^(b*c)
9^x = 9^3/2
Since the bases are the same, the exponents are the same
x = 3/2

If 40% of a number is equal to two-third of another number, what is the ratio of the first number to the second number.?
Answer:
5:3
Step-by-step explanation:
40% = 2/5
If the numbers are x and y, then
2/5 x = 2/3 y
Divide both sides by 2/5
x = (2/3 * 5/2)y
x = 10/6 y
x = 5/3 y
So the required ratio is 5 : 3.
Checking this result:
