Here we have 2 variables we need to calculate:
x - how many Volvos Jane sold
y - how many Volvos Melissa sold
We write system of equations:
x = 8*y
x - y = 35
------------
8y - y = 35
7y = 35
y = 5
x = 8*5 = 40
Jane sold 40 cars.
The pool has a diameter 20 ft so: r = 10 ft.
The pool cover extents 12 inches beyond the edge of the pool.
12 inches = 1 foot
Therefore, the radius of the pool cover is : r = 10 + 1 = 11 ft.
a. The area of the pool cover:
A = r² π = 11² π = 121 π ft²
b. The length of the rope:
l = 2 r π = 2 · 11 π = 22 π ft.
Answer:
<em>146</em>
Step-by-step explanation:
Supllementary angles add up to 180 degrees.
<em>180-34 = 146</em>
4x? because you solve the exponent
29/5 is 5.8 5.8 dividen by 9 1/2 is 0.61052631578
Hope this helps! Have a great day!!!
