Answer:
Radius: 2.3 in
Circumference: 14.1 cm
Step-by-step explanation:
Radius is half of the diameter.
Diameter=4.5
Radius=4.5/2=2.25, which rounds to 2.3
Circumference=d
=(3.14)(4.5)
=14.13
=rounds to 14.1
1 inch= 12 miles
Multiply 6 1/2 inches by total number of miles per 1 inch (12).
= 6 1/2 * 12
convert to improper fraction
= 13/2 * 12
multiply numerators
= (13*12)/2
multiply in parentheses
= 156/2
divide
= 78 miles
ANSWER: (A) 78 miles

To find the slope of the line containing the pair of points, subtract y2 to y1 and divide x2-x1.
y2-y1
--------
x2-x1
Answer:
x=3
Step-by-step explanation:
Because it is equilateral, all the sides are equal. so you can make your equation
3(2x-3)=21
Distribute the 3 throughout, giving you 6x-3=21
Subtract the 3 from both sides, and you are left with 6x=18
Divide 18 by 6 and you get 3.
Using compound interest, it is found that:
- The equation is:
- After 3 years, he has $4,252 in the account.
- After 10 years, he has $6,608 in the account.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
- t is the time in years for which the money is invested or borrowed.
In this problem:
- Jack was given $3520 from his grandma, hence P = 3520.
- The account pays 6.5% interest rate that is compounded annually, hence n = 1, r = 0.065.
Hence, the equation is:
After 3 and 10 years, respectively, the amount in dollars in the account are given by:
