A rectangle has a base of 5 inches and a height of 7 inches. If the dimensions are cut in half, what will happen to the area of
Hunter-Best [27]
Area = base * height = 35 square inches
When we make the dimensions 2.5 by 3.5 then,area = 2.5 * 3.5 = 8.75 square inches
35 / 8.75 = 4So, when we reduce the width AND the height by 2, the area decreases by 4.Why?  Because when we are reducing 2 dimensions:area = width/ 2 * length / 2 = area / 4

Naddika [18.5K]

Answer:

Jay has 8 computer games

Step-by-step explanation:

Let

x -----> the number of computer games Sherry has

y -----> the number of computer games Jay has

z -----> the number of computer games  Nairan has

we know that

x=5y ----> equation A

z=3y ----> equation B

x=z+16 ----> equation C

Substitute equation A and equation B in equation C and solve for y

5y=3y+16

5y-3y=16

2y=16

y=8

therefore

Jay has 8 computer games

A certain forest covers an area of 4900km^2. Suppose that each year this area decreases by 7.25%. What will the area be after 5
ratelena [41]

Each year, the forest decreases in area by 7.25%, which means that 92.75% of the forest remains each year.

With this, we can write a basic exponential decay equation:

4900*(0.9275)^t

Where t is the number of years past.

When you plug in 5 for t, the result shows that 3363.3005km^2 offorest will remain.

Hope this was helpful!
