Answer:
7 years
Step-by-step explanation:
Your equation <u>should</u> read = 200 * e^(.08 t) = 350
solving for t = 6.99 yrs ~~ 7 years
1188 = 2 * 2 * 11 * 3 * 3 * 3
11 has only 1 factor present so 11 must be one of the things you divide by
2 * 2 = 4 is another one. In order to have a perfect cube you need 3 prime factors not just 2
So 1188 must be divided by 11 * 4 = 44
When you do that, you get 27 which is a perfect cube.
Answer:
x = 13 1/2 or 27/2
Step-by-step explanation:
1st Add 2 to both sides: 2/3x-2+2=7+2
2nd Simplify: 2/3x = 9
3rd Multiply both sides by 3: 3*2/3x=9*3
4th Simplify: 2x=27
5th Divide both sides by 2: 2x÷2=27÷2
6th Simplify: x = 13 1/2 or 27/2
Answer:
1498.17
Step-by-step explanation:
formula A = P
where r is the rate of interest compounded and n is the number of times compounded.
r = 4.5 / 12 = 0.375 since it is compounded monthly thus need to divide by 12 months
n = 9 x 12 = 108 ( 9 years in months)
A = 1000
= 1498.167
