A ratio is an expression used to compare two quantities. A simplified ratio can be taken as is, but if a ratio has not yet been simplified, you should do so to make the quantities easier to compare and understand. In order to simplify a ratio, you divide both terms (both sides of the ratio) by the same number.
Answer:
The length if the model is 6.875 inches.
Step-by-step explanation:
1.5 inches - > 3 feet is the same as 1 inch - > 2 feet (Same ratios: 3/1.5 = 2/1)
So since this is a linear relation between values we can use the rule of three.
1 inch(model) - > 2 feet(actual object)
x inches (model) - > 13.75 feet (car)
We cross-multiply:
1*13.75=2*x - > x= 13.75/2=6.875 inches
Answer:
1 ft3= 0,028 m3
Step-by-step explanation:
We know that a 1 ft= 0,305 m,
if we cubed the above equation we have the following
1 ft3= (0,305)^3 m3
1 ft3= 0,028 m3
Answer:
a. 26 inches by 31.2 inches
Step-by-step explanation:
The lengths(X) of the rectangular is 1.2 times longer than the width (Y), so you can put it into this equation
x= y * 1.2
x= 1.2 y
The area of the window is 811.2 square inches, so you can put this equation
x * y= 811.2
Combining both equations, you can get
x * y= 811.2
(1.2y) * y = 811.2
1.2y^2= 811.2
y^2= 676
y= 26
x= 1.2 y
x= 1.2(26)= 31.2
