12% = 12/100 = 0,12
0,12 x x = 9
x = 9/0.12
x = 75
9 is 12% of 75

Step-by-step explanation:
Answer:
-1110/39 is the number
Step-by-step explanation:
We want to find the number should be added to both numerator and denominator of the ratio 29 : 36 to make it equal to 3:42
Let the number to be added be x.
Thus;
(29 + x) : (36 + x) = 3:42
The proportion symbol is essentialy a division symbol.
Thus;
(29 + x)/(36 + x) = 3/42
Cross multiply to give;
42(29 + x) = 3(36 + x)
1218 + 42x = 108 + 3x
1218 - 108 = 3x - 42x
1110 = - 39x
x = -1110/39
The scale factor is 5/3
9(5/3) = 15
Answer:
b ≈ 8.60 ft
Step-by-step explanation:
The formula of a parallelogram is
A = bh
Divide each side by h
b = A/h
b = 62⅓/7¼
b = (187/3) ÷ (29/4)
b = 187/3 × 4/29
b = 748/87
b = 8⁵²/₈₇ ft
b ≈ 8.60 ft
The base of the window is about 8.60 ft long.
