Answer:
1
Step-by-step explanation:
Here's the given:
P=$400
i=7.5%
A=$8500
The formula used for this problem is:
A = P(1+i)^t
Manipulating the equation to arrive at t, we have:
t = ln(A/P) / ln(1+i)
Plugging in values:
t = ln($8500/$400) / ln(1+0.075)

The formula which relates Distance, av.Speed and Time is

The maximal Distance would be covered if the average speed was 6.3 miles per hour.
In that case D=6.3 (mi/h) * 2 h = 12.6 mi
thus, if x represents the number of miles, x≤12.6 mi
Answer: x≤12.6 mi
Answer:
7x+54
Step-by-step explanation:
because you distribute the 7 to the x and the 8 first then you bring that down which becomes 7x+56 then you to the addition so you do 56+-2 which would give you 54.
You can think of it as two separate fractions. 1/2 divided by 3/1. You can solve this by multiplying the first fraction by the reciprocal of the second fraction. A reciprocal is switching the fraction by turning it over. So you just have to solve 1/2 multiplied by 1/3. As a result you get 1/6 as the answer! Hope this helped!
