How many hours will it take to drain all the water?

Answers

Answer:

Volume = 10562.96  cu ft

10.56 hr. to drain all the water

Step-by-step explanation:

V = 1/3Bh        B = area of the base           h = height

The base is a circle, so [tex]B = \pi r^{2}[/tex]

[tex]V = \frac{1}{3} (3.14) (29^{2})(12)[/tex] = 10562.96  cu ft

10562.96/1000  = 10.56 hr.

Find the value of x, image attached below

Answers

Answer:

x = 10

Step-by-step explanation:

Sum of angles in a triangle is 180° , so

35° + (5x + 7)° + (9x - 2)° = 180°

The value of x can now be found by solving the linear equation.

5x + 9x + 35 + 7 - 2 = 180

14x + 40 = 180

14x = 180 - 40

14x = 140

x = 140/14

x = 10

Fourteen pounds less than eight times the pounds of chocolate Jo got for her birthday is three more than four times the pounds of chocolate Jo got. How much chocolate did Jo get for her birthday?

Answers

Answer:

Total chocolates Jo bought for her birthday  = 4.25 pounds

Step-by-step explanation:

Given - Fourteen pounds less than eight times the pounds of chocolate Jo got for her birthday is three more than four times the pounds of chocolate Jo got.

To find - How much chocolate did Jo get for her birthday?

Proof -

Let Jo bought total chocolates = x pounds

Then,

8x - 14 = 4x + 3

⇒8x - 4x = 3 + 14

⇒4x = 17

⇒x = [tex]\frac{17}{4}[/tex] = 4.25

∴ we get

Total chocolates Jo bought for her birthday  = 4.25 pounds

Justification -

8(4.25) - 14 = 4(4.25) + 3

⇒34 - 14 = 17 + 3

⇒20 = 20

Satisfied.
