The surface area of a sphere is given by

where r represents the radius.
As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.
Answer:
n

65 trillion can be written as
65,000,000,000,000
or as
6.5 x 10¹³ .
Answer:
a. Let x = hours surfing and let y = hours lifting weights
b. x + y = 6
c. 100x + 75y = 500
9514 1404 393
Answer:
8. no, no, yes, yes
9. see attached
Step-by-step explanation:
8. Slope-intercept form is ...
y = mx + b . . . . . . . where m is the slope, and b is the y-intercept
You will notice that y is by itself on the left side of the equation, and that there are two terms: an x-term and a constant.
The first two equations are NOT in slope-intercept form.
The last two equations ARE in slope-intercept form.

9. The values of 3x-1 and y are the same. They are shown in the attached table.
The corresponding (x, y) pairs are (-2, -7), (-1, -4), (0, -1), (1, 2), (2, 5). In each pair, the x-value (first number) comes from the x-column of the table. The y-value (second number) comes from the f(x)- or y-column of the table.
