One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
After x weeks:
Jules will have: 1,200 + 40 x.
Kelsey will have: 400 + 50 x.
If we want to know in how many weeks will they have the same amount of money, we will make an equation:
400 + 50 x = 1,200 + 40 x
50 x - 40 x = 1,200 - 400
10 x = 800
x = 800 : 10
x = 80
Answer: In 80 weeks they will have the same amount of money.
Answer:
1.5
Step-by-step explanation:
The scale factor can be found by dividing the side length from triangle ABC by the corresponding side length from triangle ABC
so the scale factor would be equal to
12/8 and 9/6
9/6 = 1.5
12/8 =1.5
so we can conclude that the scale factor is 1.5
