The rectangle below has an area of 60y^4 square meters and a length of 30y meters. What is the width of the rectangle?

ladessa [460]

2y^3 m is the width of the rectangle

Step-by-step explanation:

Area of the rectangle = 60y^4 sq. m

Length of the rectangle= 30y m

Area = length x width

60y^4 = 30y x width

Width = 60y^4/ 30y

= 2y^3

The width of the rectangle is 2y^3 meters

Matthew threw 55 pitches in a baseball game. Of those pitches, 4/5 were strikes.

zlopas [31]

Hi there! The answer is 44.

To find our answer we have to multiply 55 by 4/5. Then we get the following:

$55 \times \frac{4}{5} = \frac{55}{1} \times \frac{4}{5} = \frac{220}{5} = 44$

Therefore, 44 of Matthew's pitches were strikes.
