The product property is the answer. You must add exponents when multiplying those with the same bases.

I think you are asking for the quotient of the numbers because base from the choices the units are meters per second and the given has units of meters and seconds. So, the quotient of the numbers is 43.218 meters per second which is option B.

A race
sashaice [31]

Answer: 187.7 mph

Step-by-step explanation:

v = 125 mph

t = 1.2 min

v2 = ?

t2 = 0.8 min

We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.

\frac{125mph}{x} =\frac{1.2min}{0.8min}

x = \frac{(125)(1.2)}{0.8}

x=187.5mph

Could someone assist me with this?
Blababa [14]

Answer:

Step-by-step explanation:

1.

Formula for Area of a parallelogram: A = bh

So multiply the base (25cm) by the height (16cm) to get 400cm^2.

2.

Volume formula l x w x h

Multiply the length of the pool (20ft) by the width (15ft) by the height (6ft) to get 1,800ft^2

3.

Formula for Area of a trapezoid A= a+b/2 * h

Where a is (12.6in), b is (15in), and h is (3.4in) just plug in the numbers into the formula to get 46.92in^2

4.

Same thing as number one, use the Area of a parallelogram formula A = bh
