Answer:
7.5 miles
Step-by-step explanation:
5 miles in 80 km
Total distance = 120 km
120- 80= 40 km
80 km = 5miles
1 km = 5miles/ 80km
120 km = 5/80 * 120 km = 7.5 miles
This is called unitary method. First we find 1 km by dividing the miles with the number of km and then multiply the number of km to find the total number of miles.
Total distance = 120 km
120- 80= 40 km
if there are 5 miles in 80 km then there will be half of the miles in half of the km . So there will be 2.5 miles in 40 km .
So the total number of miles would be
40+80 km= 5+ 2.5 miles
120 km = 7.5 miles
Answer:
30 years old
Step-by-step explanation:
Joe's age can be set to x. Since Billy is twice as old as Joe, his age can be set to 2x. They add up to 45. You can set up an equation, 2x+x=45.
Simplify the equation.
3x=45, x=15
Joe is 15. Billy is 2(15)=30.
Answer: 0.5
Step-by-step explanation:
Given: Rectangle A′B′C′D′ is the image of rectangle ABCD after a dilation.
Since dilation always produces similar images.
To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides.
AB=|-5-(-8)|=|-5+8|=3 units
A'B'=|-2.5-(-4)=|-2.5+4|=1.5 units
The ratio of the corresponding sides A'B' to AB is given by :-
hence, the scale factor of the dilation = 0.5
