Answer: 133/2π
Step-by-step explanation:
<u>Area of ends:</u>
Area of Circle = πr²
π3.5²=49/4π
There are two ends so you multiply that by 2 to get 49/2π
<u>Area of Rest:</u>
First, you need to find the circumference using the equation: πd
πx7=7π
Then to find the area you just need to multiply 7π by the height
7π x 6 = 42π
<u>Total surface area</u>
You now just need to add them together
49/2π + 42π = 133/2π
Answer:
p = 3.5 or p = 7/2
Step-by-step explanation:
-4p+9= -5
or, -4p = - 14
or, p = -14/-4
or, p = 7/2 = 3.5
They both get their cars washed on every 60th day.
You can solve this equation by finding the lcm (least common multiple):
15 30 45 60 75 90 105
20 40 60 80 100
The lowest common multiple is 60 as it is the first multiple the two have in common.
So, in sixty days, they’ll both get their car washed again
The last one, v = -2,000y + 20,000
Use the compound interest formula.
A = P*(1 +r/n)^(n*t)
where P is the principal, r is the annual rate, n is the number of compoundings per year, and t is the number of years.
For the first investment, ...
A = 208,000*(1 +.08/4)^(4*5) = 309,077.06
For the second investment, ...
A = 218,000*(1 +.07/2)^(2*4) = 287,064.37
Totaling both investments at maturity, Megan has $596,141.43.
