Pls need help been struggling hard
Reika [66]

Answer:

10. X = 2.75

11. X = 1.61

Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!

Step-by-step explanation:

10. 5x + 10 + 11x + 2 = 56

16x + 12 = 56

16/16x = 44/16

X = 2.75

11. -1 + 8x + 18x + 5 = 46

26x + 4 = 46

26/26x = 42/26

X = 1.61

~I hope I helped you! :)~

Can someone please help me answer this?

Answer:

B

Step-by-step explanation:

If you don't understand some steps, comment it for me please.

1. Find diagonal.

d = 2r

d = 2(9)

d = 18

2. Find length of square.

each length of square = x

x : 18 = 1 : \sqrt{2}

\frac{x}{18} = \frac{1}{\sqrt{2} }

\sqrt{2}x = 18

x = \frac{18}{\sqrt{2} }  = 9\sqrt{2}

3. Find area of circle and square.

Area for circle

A = \pi r^2

A = \pi (9)^2

A = 81\pi = 254.4690...

Area for square

A = (length)^2

A = (9\sqrt{2})^2

A = 162

4. Subtract area of circle to area of square.

254.4690... - 162 = 92.4690...

5. Find the shaded region.

92.4690... / 4 = 23.1172...

Rounded to the nearest hundredth = 23.12

Siobhan wants to have a beach party in January. Her parents said she can use the garage, which is 36 feet long and 20 feet wide.
ale4655 [162]
To determine how much sand she needs, we need the area of the garage

The area can be found by multiplying the width and the length

A = 36 x 20

A = 1080 feet

Now we multiply the area by the volume (2 inches of sand)

1080 * 2 = 2160

Siobhan needs 2160 feet of sand
