c. 2310 (1st pic)
circumference of circle = 2πr
44= 2 × 22/7 r
44 × 7 / (2 × 22) = r
7 = r
volume of cylinder = πr^2h
= 22/7 × (7)^2 ×15
= 2310
b. -2/x+3 (2nd pic)
(work attached)
a. 80° (3rd pic)
Total number of degrees is 180
180-(60+40)=80
c. 9 (5th pic)
(27^1/3)^2
3^2
=9
sorry i couldn't solve the 4th pic but I hope this helps!
please mark me brainliest!
Answer:
[See Below]
Step-by-step explanation:
✦ First split the equation in little pieces and solve them:
✧ 4 - 16 = -12
✧ 4 + 4² = 20 (4² = 16)
✦ Now divide them:
✧ -12 ÷ 20 = -0.6
So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.

Hello!
The degree would be one because the x in this particular equation doesn’t have an exponent, so you assume that the exponent is one because 5x to the first power is equal to 5x.
I hope this helps!
Answer:
x ≥ 7
Step-by-step explanation:
multiply both sides of the equation by 4
2x - 6
4 × ---------- ≥ 2 × 4
4
2x - 6 ≥ 8
2x ≥ 8 + 6
2x ≥ 14
2x 14
-------- ≥ ---------
2 2
x ≥ 7
It would be two, hope this helps
