Answer:

\red{ \bold{ V = \sqrt{\frac{2(E - mgh)}{M}}}}

Step-by-step explanation:

E = MV^2 ÷ 2 + mgh \\  \\ E - mgh = MV^2 ÷ 2  \\  \\  2(E - mgh)= MV^2   \\  \\  \frac{2(E - mgh)}{M}=V^2  \\  \\  \sqrt{\frac{2(E - mgh)}{M}}  = V \\  \\ \red{ \bold{ V = \sqrt{\frac{2(E - mgh)}{M}}}}

Given:

Village is spread across 240 acres of land. 37%  of land is used for the exhibits.

<h3>Solving percentages.</h3>

From the information given, Me Sanchez wants to purchase a camper, which is on sale for 10% off the original price of $85,000 and the manufacturer is offering a $2500 rebate.

Wittaler [7]

Answer:

91.46m

Step-by-step explanation:

The length of 100 yard football field in meters.

From the dimension given,

1 yard = 3 feet

Therefore,

100 yard = x feet

1 yard = 3 feet

100 yard = x feet

X = (100 × 3) / 1

X = 300 feet.

But,

1 metre = 3.28feet

X metre = 300 feet

X = (300 × 1) / 3.28

X = 91.46m

Therefore, 100 yard football field is equal to 91.46m
