Answer:

It's app. 50.24

Step-by-step explanation:

The area of a circle is A = pi * r ^2

So the area is

= pi * 16

in the question it says to use 3.14 for pi instead

so multiply 16 * 3.14 = 50.24

Answer:

50.24 square miles

Step-by-step explanation:

The formula for the area of a circle is A=\pi r^{2}

Plug in 3.14 for pi and 4 for r

when you square the 4, you get 16

16 x 3.14 is 50.24

Answer: He spends more time trading stickers by 15 minutes.
Step-by-step: 1 hour is 60 minutes. So 2 hours is 120 minutes. 120 minutes plus his 20 minutes is 140 minutes. Subtract it from his homework time and he spends 15 more minutes trading stickers.

What is the slope of the line in the graph?<br> -4/3 <br> -3/4<br> 3/4<br> 4/3
AnnyKZ [126]

Answer:

there's no graphed pictured. but slope is rise/ run so just count the boxes between the points on the line. Up and down is the numerator and sideways is the denominator. If its decreasing from left to right it's negative, and if it's increasing left to right then it's positive

Travka [436]
The expression 8(-3) represents the recession of the coastline after 8 years if the coastline recedes 3 centimeters each year. 8(-3)=-24. So, the coastline's new position is 24 centimeters farther inland than it was 8 years ago.

a line intercects the points (-22,-14) and (-18,-12). what is the slope intercept equation for this line?
Nadya [2.5K]

Answer:

y = \frac{1}{2} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 22, - 14) and (x₂, y₂ ) = (- 18, - 12)

m = \frac{-12+14}{-18+22}  = \frac{2}{4} = \frac{1}{2}

y = \frac{1}{2} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (- 22, - 14), then

- 14 = - 11 + c ⇒ c = - 14 + 11 = - 3

y = \frac{1}{2} x - 3 ← in slope- intercept form
