Answer:
D
Step-by-step explanation:
3(2x-2)+5x
11x-6
The brake horsepower of an engine that’s being tested is coupled to a dynamometer that has a radius arm of 1.70 feet is letter D. 170.
The width is the first numbers.
Width = 225 mm
Aspect ratio is the second number.
Aspect ratio is 45
Aspect ratio is width / height.
You have the ratio and width so you can calculate the height:
Multiply the width by the ratio:
Height = 225 x 0.45 = 101.25 mm
101.25/25.4 = 3.98 inches
The rim
Diameter is the last number
Rim diameter = 17 inches
So the overall height would be approximately 17 + 3.98 + 3.98 = 24.96 inches
Round the answers as needed.
One way is to turn them into fractions and simplify them then see if they are equal exg
8:4 and 6:3
turn into fractions
8/4 and 6/3
2/1 and 2/1
equal
300m because area is Length x width and it's 3x as big as 10 meters it's 30 x 10= 300
