The surface area of a sphere is:  4pr^2

(4p(36^2)ft^2)(gal/160ft^2)

(5184p ft^2)(gal/160ft^2)=32.4p gal which is approximately:

101.78 gal

So the company must purchase 102 gallons of paint.

20. If a certain linear function f(x) is evaluated at 0, the answer is 4.
bija089 [108]

Answer:

y = (1/3)x + 4

Step-by-step explanation:

Two points on this line are (0, 4) and (3, 5).

As we move from the first point to the second, x increases by 3 and y increases by 1.  Thus, the slope, m, of the line is m = rise / run = 1/3.

Use the slope-intercept equation:  y = mx + b.

If we use the data from the point (0, 4), we get:

4 = (1/3)(0) + b, so that b = 4.  The desired equation is y = (1/3)x + 4.

How do you tell if it's possible to make a triangle out of these side lengths?<br> PLZ HELP!!!!!
Nastasia [14]

Answer:

A

Step-by-step explanation:

square root of 73 is about 8.5

square root of 10 is about 3. multiply by 3, you get 9.

square root of 7 is about 2.6. multiply by 5, you get 13.

when determining if you can make a triangle, if all variants of two sides can add up to be greater than the third side, you can make the triangle. so 8.5+9 > 13; 13+9 > 8.5; 13+8.5 > 9. this means it can make a triangle and all you have to do is order the sides.

8.5 is smallest which corresponds to angle c because it's opposite. 9 goes to angle a, then finally 13 goes to angle b. thus, angles c, a, b is the order.

side note: the smallest side length will always correspond with the smallest angle.

hope this helps :)

What means the same as 6 × 5? <br> A.6^5 <br> B.5 + 5 + 5 + 5 + 5 <br> C.6 + 6 + 6 + 6 + 6
skelet666 [1.2K]

Here is your answer:

In order to find your answer we will have to solve each option separately to see which one equals 6 × 5.

  • 6^5 = 6\times6\times6\times6\times 6 <---- Not the answer
  • 5 + 5 + 5 + 5 + 5 = 25 <----- Not the answer
  • 6 + 6 + 6 + 6 + 6 = 35 <---- Your answer

Therefore your answer is option C "6 + 6 + 6 + 6 + 6 ."

Hope this helps!
