elixir [45]

Answer:

It took the cell phone 4.15 seconds to reach the ground

Step-by-step explanation:

The formula is $t=\frac{\sqrt{h}}{4}$ , where t is the time and h is the height

The height of that the cell phone dropped from it is 275 feet above the ground

∴ h = 275

- Substitute the value of h in the formula to find t

∵ $t=\frac{\sqrt{275}}{4}$

∴ $t=\frac{5}{4}\sqrt{11}$

- Change it to decimal

∴ t = 4.15 seconds to the nearest 2 decimal places

It took the cell phone 4.15 seconds to reach the ground

The length of a rectangle is three more than twice the width. The perimeter is 96. What are the dimensions?

SIZIF [17.4K]

Answer:

Width =15

Length =33

Step-by-step explanation:

Take width as x

And length as 2x+3

Perimeter as 96

Formula of the perimeter of a rectangle is 2l+2w

X+×+2×+3+2×+3=96

6x+6=96

6x=96-6

6×=90

X=15

Width =x and x =15 so width =15 while length =33
