If Susan had a total of 960 minutes to use, and currently she has 188 minutes left then you would subtract 960-188 to get the amount she already used.

960-188=772

To check the answer, you would add the amount she used (772) to the amount she has left (188) to get the total she had at the beginning of the month. 772+188=960

Answer:

No, The answer should be 240

Step-by-step explanation:

  1. The first step to finding the Surface Area was done well and was right but you got confused when trying to add the area of each shape
  2. There is 3 Rectangles and 2 Traingles.
  3. Let's start with the area of the triangles. 1/2bh is the formula for finding area of Traingles. 1/2(4)(6) = 12. We have two Traingles so that would be 24.
  4. Now we have three rectangles with different lengths we need to calculate.
  5. Rectangle 1 = 12 * 8 = 96
  6. Rectangle 2 = 12 * 6 = 72
  7. Rectangle 3 = 12* 4 = 48
  8. 24+96+72+48 = 240.
  9. So, the surface area of the rectangular prisim is 240

Answer:

y = 3x + 1

Step-by-step explanation:

Consider the differences between consecutive terms of y

1 → 4 → + 3

4 → 7 → + 3

7 → 10 → + 3

10 → 13 → + 3

13 → 16 → + 3

The differences are constant, the constant is the multiplier, that is

y = 3x

Given the point (0, 1 ) , thus add 1 to the 3x term , hence

y = 3x + 1 ← equation relating x and y

If 36 sqrt2 - 24 sqrt2 = sqrtN, what is N?
topjm [15]
N = 288

First, both 36 sqrt 2 and 24 sqrt 2 have the common sqrt 2, which means you can directly subtract them.

36 sqrt 2 - 24 sqrt 2 = 12 sqrt 2
12 is outside of the square root means it was a perfect square, thus 12*12 = 144.

There's still a 2 left in the sqrt, and 144 * 2 = 288.
