Answer:
She runs for 1.6 hours
Step-by-step explanation:
For this, one way to do it is to just set 1 hour over 4 miles equal to x hours for 6.4 miles. The reason this is done is because if the speed is constant that means the rate stays the same, which means the ratio of miles to hours should always be the same, so the two ratios must be equivalent.
1/4 = x/6.4
Multiply both sides by 6.4 to get x by itself:
6.4/4 = x
1.6 = x
Hope that helps!

Answer: $75.83
Step-by-step explanation:
Seth needs $9,100 and his grandparents will pay 70% of this:
= 9,100 * 70%
= $6,370
The amount Seth has to save for is therefore:
= 9,100 - 6,370
= $2,730
He has 3 years to save for it and wants to save monthly. In months this is:
= 3 * 12
= 36 months
Minimum amount to save every month is:
= Amount to save/ Number of months
= 2,730 / 36
= $75.83
I’m not sure about the first but I know the second one is right angles
It think the answer is 450
