Jane’s cell phone plan is $40 each month plus $0.15 per minute for each minute over 200 minutes of call time. Janes cell phone b

san4es73 [151]

Answer:

The equation is $40+0.15m = 58.00$ whose solution is $m =120\:minutes.$

Step-by-step explanation:

Let us call $m$ the number of minutes the phone is used over 200 minutes, then we have

$\boxed{40+0.15m = 58.00}$ (this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )

This equation can be used to solve for $m$ u as follows:

$0.15m = 58-40$

$m = \dfrac{18}{0.15}$

$\boxed{m = 120\:minutes}$

Please help. I will give brainliest to correct answer.

Stells [14]

Answer:

The area of a square with side length of 2 inches is 4 square inches.

The area of a circle with radius 1.2 inches is:

$\pi \times (1.2) ^{2} \\ = 3.14 \times 1.44 \\ = 4.5216 \: square \: inches$

That is approximately 4.5 square inches.

Hence, the area of the square (4) is less than {<} that of the circle (4.5)!
