Answer:

(2A)/h -a =b

Step-by-step explanation:

A= [h(a+b)]/2       I rewrote the formula, because h and a+b are in the numerator.

2A=h(a+b)  Multiply both sides of equation by 2

(2A)/h= a+b Divide both side by h

(2A)/h -a= b Subtract a from both sides

to estimate the speed of a car, v, in miles per hour, based on the length, L, in feet, of its skid marks when suddenly braking o
Leno4ka [110]

Answer:

69.6 miles per hour

Step-by-step explanation:

Length of the skid marks = 242 feet

The formula used for the velocity is

v=2\sqrt{5L}

where, L is the length of skid marks in feet and the velocity obtain has the units of miles per hour.

By substituting the value

v=2\sqrt{5\times 242}

v = 69.6 miles per hour

Thus, the speed of the car at the time of accident is 69.6 miles per hour.

The area of a rectangle is 117117117 square meters. The width is 999 meters.
ki77a [65]

Area = 117 m²      width = 9 m

Area (A) = length (L) x width (w)

  117      =      L          *      9

117 = 9L

\frac{117}{9} = \frac{9L}{9}

13 = L

Answer: length = 9 m

How many cubes eith side lengths of 1/4 cm does it take to fill the prism? Please help
valina [46]

Step-by-step explanation:

In order to find Volume for a rectangle use the formula: L * W * H

2 1/4 * 3/4 * 1 1/4 = 2 7/64

A cube with the side lengths of 1/4:   1/4 * 1/4 * 1/4 = 1/64

Divide 1/64, by the prisms volume, 2 7/64 to get 135.

I'm not sure if this is right, but I hope that helps! :)
