65mph
John drove a total of 200 miles (40mph•5)
655-200= 455 miles
Charlie drove this in seven hours, and 455mi/7hours = 65mph
The balance after 8 years is $22,942.67
<h3>
What is the balance after 8 years?</h3>
We know that the savings account earns 15% annually, and the initial deposit is $7500, then the balance as a function of time in years is:
B = $7500*(1 + 15%/100%)^t
B = $7500*(1.15)^t
The balance after 8 years is what we get when we evaluate the above function in t = 8, so we get:
B = $7500*(1.15)^8 = $22,942.67
So the correct option is the last one.

Answer:
Radius = 504units
Step-by-step explanation:
Angle = 10°
Length of arc = 28π units
L = ∅/360 × 2πr
28π = 10/360 × 2πr
28π = 1/36 × 2πr
2πr = 28π × 36
π cancelled off.......
2r = 28 × 36
r = (28 × 36)/2
r = 28 × 18
r = 504units
Answer:
25^4
Step-by-step explanation:
Here, we want to find the expression that shows the total number of pages in all of the news papers
Number of pages per book = 25
Number of schools is 25
Number of classrooms is 25
Number of students per classroom is 25
Now; the number of students in each school
is 25 * 25
Number of students in all of the school will be;
25 * 25 * 25
So the number of pages in all of the schools will be;
25 * 25 * 25 * 25 = 25^4
