Step-by-step explanation:
1. Find the numerator:
2. Simplify the fraction:
Answer:
64 : 27
Step-by-step explanation:
When using scale factors
Length = scale factor
Area = scale factor squared
Volume = scale factor cubed
The ratio is 4:3
The ratio of the volume is 4^3 : 3^3
64 : 27
Answer:
x = 7
Step-by-step explanation:
The perimeter of triangle is A = a + b + C, the sum of the three sides.
P = 30 and the three sides are x + (2x - 1) + (x + 3)
30 = x + (2x - 1) + (x + 3) combine like terms together
30 = (x + 2x + x) + (-1 + 3) Add like terms
30 = 4x + 2
30 - 2 = 4x Subtract 2
28 = 4x Simply
7 = x Divide by 4
Check x = 7; x + 3 ; 2x - 1 7 + 10 + 13 = 30
7 + 3 = 10 2(7) - 1
14 - 1 = 13
