Answer:
x = 7
Step-by-step explanation:
The sum of the interior angles is 90°, so you have ...
(7x +8) +(5x -2) = 90
12x = 84 . . . . subtract 6; next, divide by 12
x = 7
Answer:
14%
Step-by-step explanation:
A = P(1 +rt) . . . . . . . . . . . . . . . . . . formula for the balance for simple interest
2848.52 = 2006(1 +3r) . . . . . . . filling in the given numbers
1.42 = 1 +3r . . . . . . . . . . . . . . . . . .divide by 2006
0.42 = 3r . . . . . . . . . . subtract 1
0.14 = r = 14%

If you subtract the volume of the sphere from the cone, you'll get the volume you can fill with flavored ice. Right?
So that means, The volume left to put in flavored ice is :
So putting in the value for radius and height of the cone and radius of the sphere in the 2nd term will do the thing, I think.
.......
Okay, I think they didn't raise the power but wrote the exponent beside the number. It must be c. They wrote 32 so as to say 3^2 and wrote 0.553 to say (0.55)^3
So the answer is (C)
Hope this helped you. Brainliest would be nice!
Answer:
x = 3.8
Step-by-step explanation:
The equation is (5 - x) / 2 = 2x - 7
Multiply both sides by 2:
5 - x = 4x - 14
Add 14 to both sides:
19 - x = 4x
Add x to both sides:
19 = 5x
Divide both sides by 5 to isolate x:
3.8 = x
Therefore, x = 3.8.
