SOMEONE HELP PLS IM STUCKKKK
Answer:
111 =x
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
29+82 = x
111 =x
Answer:
Step-by-step explanation:
Since all the angles in a triangle add up to 180, you would need to add up the 2 values you have to get the third:
∠3 = 180-82-29
= 69 degrees
Now you have to subtract this value from 180 because a straight line is 180 degrees:
∠x = 180-69
∠x = 111°
Hope this helps!

Forgive me if I got a few wrong in the inches system. From where I am, we use the metric system and different syllabus. There's some answers I'm quite unsure so make sure to check with someone else
Answer:
1. 24 in
2. 30 in.
3. 14/3/13 in
4. 7 in
5. 5in
Step-by-step explanation:
The scale of drawing to the scale of actual model:
1:6
so when the questions ask for actual, we need to x6.
1. actual width of painting = width of drawing x 6
4in x 6 = 24in
2. actual height of painting = height of drawing x 6
5in x 6 = 30in
3. This one you should take 5/6 and x2 since we have two edges so like
5 - 2(5/6) = 3/1/3
4 - 2(5/6) = 2/1/3
so the final equation should be:
3/1/3 + 2/1/3 x 6 (since we are looking for the actual height of H) = 14/3/13 in
4. actual width of H through center = 1inch + 2(1/2)in (because we have 2 vertical parallel) x 6 so:
2(1/2) + 1in x 6 = 7in
5. Look back on Q3,
drawing top edge to top edge of H = drawing left edge to left edge to H = 5/6
so, 5/6 x 6 = 5in
Hope I could help in someway
I don’t know how to do these questions so help plz
Answer:
the anser is no.b that is 30°
Answer:
90°
Step-by-step explanation:
There's are supplementary angles at point C. These are two angles that add up to 180°. We know this because a straight line makes 180° on both sides. Since we know that the first angle is 150°, we can determine the angle a point C is 30°. This is shown by:
180-150=30
So now we know 1 angle and the other two angles are put into like terms (in this case, multiples of x). It is known that the sum of all angles in a triangle equates to 180°. Using this information we can set up a simple equation.
[tex]3x+2x+30=180[/tex]
Combining like terms, we get:
[tex]5x+30=180[/tex]
Isolating x, we get:
[tex]5x=150[/tex]
Dividing both sides by 5, we get:
[tex]x=30[/tex]
So now we can use this x-value to determine the angle that is being asked. It is shown that angle ABC is equal to 3x. Using the x value we just calculated, we get a final answer of:
[tex]3x=3(30)=90[/tex]
Therefore, the answer is 90°. Hope this helps!
What is the diameter of a hemisphere with a volume of 896\text{ m}^3,896 m
3
, to the nearest tenth of a meter?
diameter=15m
Answer:
Solution given:
diameter [d]=?
Volume of hemisphere=2/3*πr³
896m³=2/3*πr³
r³=896*3/2π
r=[tex]\sqrt[3]{427.8}=7.5[/tex]
diameter=2r=2*7.5=15m
Radius (r) = ?
Diameter (d) = ?
Volume of hemisphere = 2/3 × πr³
→ 896m³ = 2/3 × πr³
→ r³ = 896 × 3/2π
→ r = ³√427.8
→ r = 7.5
Now,
Diameter (d) = 2r
→ 2 × 7.5
→ 15m is the required answer.

How do you rewrite an equation by completing the square?
x^2+10x+21=0
Answer:
Step-by-step explanation:
x²+10x+21=0
x²+10x+(10/2)²-(10/2)²+21=0
x²+10x+25-25+21=0
(x+5)²-4=0
(x+5)²=4
(x+y)²=(x+y)(x+y)=x(x+y)+y(x+y)=x²+xy+xy+y²=x²+2xy+y²
(x+y)²=x²+2xy+y²
coefficient of x=2y
y²=[(coefficient of x)/2]²=(2y/2)²=y²

Marion and her friends are driving to see a concert at the stadium, a trip of 145 miles. They drive for 2 hours at a steady rate of 40 miles per hour and then stop for gasoline. How much further do they have to travel to arrive at the stadium?
Answer:
65
Step-by-step explanation:
Since they drove for 2 hours at an average rate of 40 miles per hour, they've travelled [tex]40\cdot 2=80[/tex] miles so far. Therefore, they still have [tex]145-80=\boxed{65}[/tex] miles to go.
Answer:
65
Step-by-step explanation:
Since u traveled for 2 hours at 40 miles per hour, you have traveled for 80 miles. Then u subtract the total miles, 145 by 80
145-80
= 65 more miles

What is the area of a circle that has a diameter of 16in? A: 50.24 square inches B: 803.84 square inches C: 200.96 square inches D: 25.12 square inches
Answer:
A = 200.96 in² (Answer C)
Step-by-step explanation:
The formula for the area of a circle of radius (not diameter) is A = πr².
Here the diameter is 16 in, so the radius is half that, or 8 in.
Then the area of the circle in question is
A = π(8 in)² = 64π in²
If tis is evaluated, we get A = 200.96 in² (Answer C)

Solve for x.
Please helppp
Answer:
x = 23
Step-by-step explanation:
2x + 19 + 5x = 180
I say this because it is an angle that is equivalent to the one adjacent to 2x+19, which is on a straight line. That means it is equal to 180.
7x + 19 = 180
180 - 19 = 7x
161/7 = x
x = 23
Step-by-step explanation:
5x+2x+19=180
7x+19=180
7x=180-19
7x=161
x=161/7
x=23

Mallory goes to the farmers market every weekend. She buys six apples for $0.75 each and a bagful of oranges that are priced at $1.25 per orange. The total charge is $14.50. Write the equation representing this situation where n represents the number of oranges.
Answer:
Number of oranges = 8
Step-by-step explanation:
let
a = number of apples
n = number of oranges
Number of apples = 6
Cost of each apple = 0.75
Number of oranges = n
Cost of each orange = $1.25
Total cost = $14.50
Total cost = Number of apples * Cost of each apple + Number of oranges * Cost of each orange
14.50 = 6 * 0.75 + n * 1.25
14.50 = 4.5 + 1.25n
14.50 - 4.5 = 1.25n
10 = 1.25n
n = 10 / 1.25
n = 8
Number of oranges = n = 8
Therefore, there are 8 oranges in a bagful of orange

In △XYZ, m∠X = 27° and m∠Y = 48°. Which gives the sides of the triangle in order from shortest to longest?
Answer:
YZ , XZ , XY
Step-by-step explanation:
first lets find angle Z
angle x + angle y + angle z=180 degree (being sum of interior angles of a triangle)
27 + 48 + angle z=180
75 + angle z=180
angle z =180-75
angle z =105 degree
side YZ is the shortest one because the side opposite to the smallest angles is shortest in side.Then ,XZ is shortest in side because the side opposite to the smallest angle is shortest in side.Since angle z is largest angle so the side opposite to angle z will be the longest side i.e XY
first YZ then XZ and XY.

Answer:
x = 8
Step-by-step explanation:
A² + B² = C²
x² + 15² = 17²
x² + 225 = 289
x² = 289 - 225
x² = 64
x = [tex]\sqrt{64}[/tex]
x = 8

What is it yalll !??????
Answer:
I think b
Step-by-step explanation:
Answer:
As x reaches negative infinity y reaches negative infinity
Step-by-step explanation:
So, first off, when looking at graphs, there will always be a infinite end behavior.
This is because either the x or y axis can be set to a infinitly large number.
We can instantly set up a 2 things for this graph.
We see that y NEVER reaches postive infinity. This is because both left and right sides of the graph have downwards slopes.
This removes our second answer, because it is postive infinity for y.
It also removes our first answer, since it is just 5 for y, notn negative infinity.
Finally, it removes our third answer, since it is just 7 for y, not negative infinity.
This leaves D.
D is correct since y reaches negative infinity when x reaches both postive and negative infinity.
D says x is negativly infinite, which fits this.
So D is our answer.
Hope this helps!

Sthephanie has 3 3/4 bags of soli to put in her garden. Each bag of soil will cover 125.3 ft how many square feet will sthephanie be able to cover if she uses all bags of soli?
Answer:
469.875 square feet
Step-by-step explanation:
Find how many square feet she can cover by multiplying 125.3 by 3.75 (same as 3 3/4):
125.3(3.75)
= 469.875
So, she will be able to cover 469.875 square feet with soil

Write an equation of a line in slope-intercept form for the
given conditions.
passes through (4,33) and (1,21)
Answer:
The desired equation is thus y = 4x + 17
Step-by-step explanation:
The slope-intercept form of the equation of a straight line is y = mx + b. There are two values to find: slope m and y-intercept b.
The line passes through (4, 33). Thus, 33 = m(4) + b.
The line also passes through (1, 21). Thus, 21 = m(1) + b, or m = 21 - b.
Thus we have a system of linear equations to solve, and will use the substitution method:
Substitute 21 - b for m in 33 = 4m + b:
33 = 4(21 - b) + b, which, in expanded form, is 33 = 84 - 4b + b, or
33 = 84 - 3b, of
-51 = -3b.
Thus, b = 17. Since m = 21 - b, when b = 17, m = 21 - 17 = 4
The desired equation is thus y = 4x + 17
Of course there are other ways to find this equation. You could, if you wished, find the slope of the line passing through the given points using the definition of slope, and then find the y-intercept.
