Answer:
a.) 61 square feet
b.) $152.50
Step-by-step explanation:
first you find the area for the rectangle
LxW=A
10x4=40
then you find the area for the triangle
(bxh)1/2=a
(6x7)1/2=21
-we get 7 from adding the height that we know (3ft) and using logic, a rectangle has equal parallel lines so the dotted line has to equal 4ft. so 3ft+4ft=7ft
then you add both areas together
40 square feet+21 square feet= 61 square feet
<em>Now</em><em> </em><em>for</em><em> </em><em>B</em><em>.</em><em>)</em>
as we know, the area of the room floor is 61sq feet. so by multiplying 2.5 and 61 you get the cost as $152.50

It's pretty straightforward. The number of people increases at an increasing rate as the months pass.
Answer:
Step-by-step explanation:
![\frac{1}{\sqrt[5]{7}}=\frac{1}{7^{1/5}}=7^{-1/5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%5B5%5D%7B7%7D%7D%3D%5Cfrac%7B1%7D%7B7%5E%7B1%2F5%7D%7D%3D7%5E%7B-1%2F5%7D)
Answer:
28mph
Step-by-step explanation:
Let the speed at which Pat drives be xmph.
Now, we know John travels 32mph faster than Pat. Hence, John's speed is (x + 32)mph
The total distance is 440 miles.
Distance = Speed × Time
The distance traveled by each of them after 5 hours is given as follws;
Pat = 5 × x = 5x miles
John = 5(x + 32) miles
Now, if we add both distances, we get the total of 440 miles.
Hence, 5x + 5(x + 32) = 440
5x + 5x + 160 = 440
10x + 160 = 440
10x = 440 - 160 = 280
10x = 280
Hence, x = 280/10 = 28mph
