12. Volume of sphere = (4/3)πr³

= 500/3π

= 524 in³ (3 sig. fig.)

13. Volume of cylinder = πr²h

= 7²π(13)

= 637π

Shtirlitz [24]

Answer:

x = 23

7x - 11 = 4x + 58

(7x - 4x) - 11 = (4x - 4x) + 58

3x - 11 = 58

3x (- 11 + 11) = 58 + 11

3x = 69

3x/3 = 69/3

x = 23

Lemur [1.5K]

Answer:

The solution is  (2,6)

Step-by-step explanation:

Let

x-----> the number of hours to change a fuel injection unit

y-----> the number of hours to change a transmission

we know that

5x+10y=70 -----> equation A

8x+8y=64 -----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (2,6)

Which of the following could be true if y ≤ -75?
ch4aika [34]

Hello!

Lets go through each choice, and determine if it is correct.

So, the symbol ≤, means less than or equal to. So our answer must be less than -75 or -75 on the dot.

A: y = 75

Okay, so we can tell this one is wrong off the bat. 75 is much more than -75. (Make sure you notice the symbol!) So it cannot be equal to said answer. A is wrong.

B: y =-74

Another trick question! When you are in the negatives, less is more! So -74 is actually greater than -75. This is also incorrect!

C: y > -75

This one is straight forward. Our equation up top strictly says <em>less than or equal too</em>, while C says greater than. Incorrect!

D: y = -75

The last answer! We see that the symbol in our equation up top says less than or equal too, and y = -75 is equal. This is the correct answer.

Our correct answer is D: y = -75
