find the measure of the angle indicated for each trapezoid

Answer:

Solution:

Given,

Radius(r) = 11 ft

C = ?

Now,

[tex]c = 2\pi \: r[/tex]

C = 2 × 3.14 × 11

= 70 cm

again,

C = 360°

angle = 315°

So,

C = 70 cm

or, 360° = 70 cm

or 1° = 70/360°

or 1° = 7/36

again ,

area = 7/36 × 315°

= 61.25 cm

Answer:

261 cm²

Step-by-step explanation:

To find the surface area of a square pyramid, you must first recognize all of the shapes.

There are four triangles and one square.

The triangles have a base of 9 and a height of 10.

[tex]9*10=90[/tex]

Multiply the product by 1/2.

[tex]90*1/2 = 45[/tex]

There are four triangles.

[tex]45*4=180[/tex]

The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.

There square has sides of 9 centimeters.

[tex]9*9=81[/tex]

The area of the square is 81 centimeters.

Lastly, we add the areas of the shapes.

[tex]45+45+45+45+81 = 261.[/tex]

Therefore, the surface area of this square prism is 261 cm².

You can use this layout to find the surface area of a square pyramid.

Answer:

A

Step-by-step explanation:

Multiply [tex]\frac{x}{\sqrt{2} }[/tex] by [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex] and you would get [tex]\frac{x\sqrt{2} }{2}[/tex] because [tex](\sqrt{2 } )^{2} =2[/tex]

Answer:

Option A, Shannon paid $ 7 per hour to labor than Joni

Step-by-step explanation:

Total amount paid by Shannon = $339.50

Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)

Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5

Total cost of 1 hours of labor paid by Shannon  $65 per hour

Total amount paid by Joni = $455

Total cost of 2.5 hours of labor paid by Joni =  $455- $$310

Total cost of 1 hours of labor paid by Joni = $145/2.5

Total cost of 1 hours of labor paid by Joni = $ 58

Hence, Shannon paid $ 7 per hour to labor than Joni

Answer and Step-by-step explanation:

This triangle is a right triangle.

- Acute angles are angles that have a degree that is less than 90 degrees.

- Obtuse angles are angles that have a degree that is more than 90 degrees.

- Right angles are angles that are 90 degrees.

It has 1 angle that is 90 degrees, so it is a right triangle.

Answer:

The investor will earn $875 over the course of 3.5 years.

Step-by-step explanation:

Sounds like simple interest (not compound interest).

The appropriate formula is i = prt, which here is

i = $5000(0.05)(3.5) = $875

The investor will earn $875 over the course of 3.5 years.

Answer:

0 - 9 = 1

10 - 19 = 2

20 - 29 = 2

30 - 39 = 4

y = 4x + 1

Step-by-step explanation:

Find slope, rise over run

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}} = \frac{-3--7}{-1--2} = \frac{4}{1} = 4[/tex]

find y intercept by plugging in one of the coordinates in  y=mx+b, including m=4

-7 = 4(-2) + b

1 = b

Answer:

31, 7, 3.48, 3, 2.96

Step-by-step explanation:

Look at the ones value first. 31 is the highest. Then 7. Between 3 and 3.48, think of 3 as 3.00 so therefore 3.48 is higher than 3.00

Answer:

1/1560

Step-by-step explanation:

The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.
