Answer:

Hiiiiiiii ! :) so here's a step by step explanation okay, starting with the first step below. Hope it helps you ! :) :)

Step-by-step explanation:

Begin with the volume of water:

V = πr²×h = π×(9m)²×2.5m = 636.17m³

Weight of water = 636.17×10³kg

G force on water = 9.8m/s²×636.17×10³kg = 6,234.49kN

Water's center of gravity is 2.75m below edge of pool.

(2.5m/2 = 1.25m, 4m - 1.25m = 2.75m)

Work = force × distance = 6,234.49kN × 2.75m = 17,144.85

Hope i helped. <3

An individual is at a restaurant with two other people and they are trying to determine the tip for their check total which came

zlopas [31]

Answer:

c. The tip is $10.00

Step-by-step explanation:

The total bill in the restaurant is = $ 68.42

They wanted to pay a gratuity of 15%

Therefore the correct tip can be calculated as :

= 68.42 of 15%

= $68.42 \times \frac{15}{100}$

= 68.42 x 0.15

= 10.263

≈ 10 (approx.)

Thus the individual along with the other two wishes to pay a tip $10.00 for the total value.

What is the rate of change from 1 to 3

lana [24]

The rate of change is (amount of the change) / (time it took to change) .

Amount of the change = (3 - 1) = 2 .

Rate of change = (2) / (time it took to change from 1 to 3) .

ZE and ZF are vertical angles with mZE = 8x + 8 and mZF = 2x +38. What is the value of x?

Dovator [93]

Answer:

Since ZE and ZF are vertical angles, they are congruent.

8x+8 = 2x+38

8 = 2x-8x+38

8 = -6x+38

8-38 = -6x

-30 = -6x

x = -30/-6

x = 5

Part A: Solve –mk – 90 > 85 for m. Show your work.

erma4kov [3.2K]

Answer:

A) m < -175/k and B) 3c/5 - 11

Step-by-step explanation:

A) Add 90 to both sides. -mk > 175.

Next, divide both sides by -k. Because you divide by a negative, don't forget to reverse the sign!

m < -175/k.

B) Subtract 3c from both sides.

-5f = 55 - 3c.

Now multiply both sides by -1/5.

f = 3c/5 - 11
