Volume of a sphere = 4/3 pi r^3
36 pi = 4/3 pi r^3
36 = 4/3 r^3
27 = r^3
r = 3 inches
Y= 20x+10
150= 20x+10
Subtract 10
140= 20x
Divide by 20
X= 7 number of people
Hello!
To find the slope, let's first distinguish two coordinates. It looks like (-2, 3) and (0, -1) are points on the line.
To find slope, we use the form y1 - y2 / x1 - x2; this means we'll divide the difference of the y-values by the difference in the x-values. Let's plug in our x- and y-values and solve.
3 - (-1) / -2 - 0
3 + 1 / -2
4 / -2
-2
The slope of the line is -2. The answer is A.
Answer:
(1.5)x
Step-by-step explanation:
90 minutes = 1.5 hours therefore
if car travels x miles in 1 hour
then the care has to travel (1.5)x miles in 90 minutes
