2 rectangle shaped
1) Length = 160 mi ; Width = 40 mi
2) Length = 440 mi - 160 mi ; Width = 240 mi - 70 mi

1 triangle shape
1) base = 70 mi ; height = 440 mi - 160 mi

Area Rectangle 1 = 160 mi * 40 mi = 6,400 mi²
Area Rectangle 2 = 280 mi * 170 mi = 47,600 mi²
Area Triangle 1 = ((440 mi - 160 mi) * 70mi)/2 = (280mi * 70mi)/2 = 9,800 mi²

Total Area = 6,400 mi² + 47,600 mi² + 9,800 mi² = <span>63,800 mi²</span>

You can write it several ways. Here are two:

1) Proportion
160/1.00=x/0.95
(160 is the whole, 1.00 or 100%, and x is 95% of the whole. Solve for x.)
x=<u>160*0.95<em /></u>  = 152/1 = 152<u>
</u>         1.00

2) Simple multiplication expression
"of" in math almost always means "multiply"
95% becomes 0.95. Multiply 0.95 by 160 to get your answer.
0.95*160=152

Either way, you get <u><em /></u><em />152, so that is your final answer.

The distance traveled, in feet, of a ball dropped from a tall building is modeled by the equation d(t) = 16t2 where d equals the
nignag [31]

Assuming that by "16t2" you mean 16t^2:


First of all, let's compute the position at the two required times:


d(2)=16\cdot 2^2 = 16*4 = 64


d(5)=16\cdot 5^2 = 16*25 = 400


So, the ball traveled a total distance of \Delta d = 400-64 = 336, during the time \Delta t = 5-2 = 3.


The average rate of change is the ratio between these two:


\frac{\Delta d}{\Delta t} = \frac{336}{3} = 112

Answer:

108

Step-by-step explanation:

<u>find the volume of the cooler</u>:

V=πr²h

π×6²×16= 1809.56

<u>find the volume of the cup</u>:

V=πr²(h/3)

π×2²×(4/3)= 16.76

<u>divide the volume:</u>

1809.56/16.76= 107.969

Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.
