Answer:
The first one should be right. Since the teacher is charging $15 per hour of the piano lesson then it can't be any of the answers of $100h. The answer can't be C, the third one, since you're adding the enrollment fee to the cost of every piano lesson it would be wrong to subtract the $100. Hope that helps!
Step-by-step explanation:
The answer will the answer on the top $25=$100+$15h over h
The Area of the square is (side)^2
side is given to be 2^(4/9)
SO,
side^2 = [2^(4/9)]^2 = 2^(4/9 * 2) = 2^(8/9)
so the area of square is 2^(8/9) sq. inches.
Answer:
Andy ate 9 doughnuts because 21-9=12
12-9=3.
Cylinder Volume = PI * radius ^2 * height
52 = PI * radius ^2 * 4
radius ^2 = 52 / (PI * 4)
radius ^2 = 52 / 12.5663706144
radius ^ 2 = 4.1380285204
radius = 2.0342144726
OR a good approximation of the radius is 2 inches
Answer:
5. $62.31 ÷ 3 = $20.77
$20.77 + $3.66 = $24.43
C. $24.43
1. 8,844.43 - (-424.3)
8,844.43 + 424.3 = 9,268.73
D. 9,268.73 meters
2. 10/25 = 0.4
300 × 0.4 = 120
C. 120
9. $43.85 + 2($2.70) = $49.25
$49.25 - 2($1.10) = $47.05
$47.05 - $4.45 = $42.60
B. $42.60
10. $174.99 - $24.99 = $150
$150 ÷ $12.50 = 12
C. 12 months
11. (4y = 3x) ×2 = (8y = 6x)
C. 1 and 3
12. 50 - 37 1/2 = 12 1/2
12 1/2 ÷ 1 3/4 = 7.14
D. 7 or less
