Step-by-step explanation: your have to measure the length by width(6x12) then subtract 12 from 20 which is 8 then divide by 2 and you get 4 so when you have 6x4=24÷2(because its a triangle)=12 since theres 2 triangles multiply by 2 so add 12+12+72 and you get 96

Answer:

\frac{3}{5}x+2=\frac{2}{3}x\\\\\frac{3}{5}x+2-2=\frac{2}{3}x-2\\\\\frac{3}{5}x=\frac{2}{3}x-2\\\\\frac{3}{5}x-\frac{2}{3}x=\frac{2}{3}x-2-\frac{2}{3}x\\\\-\frac{1}{15}x=-2\\\\\left(-\frac{1}{15}x\right)\left(-15\right)=\left(-2\right)\left(-15\right)\\\\x=30

hope this helps you

Find the doubling time of an investment earning 7% interest if interest is compounded continuously
Alex

Answer:

The doubling time of this investment would be 9.9 years.

Step-by-step explanation:

The appropriate equation for this compound interest is

A = Pe^(rt), where P is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.

If P doubles, then A = 2P

Thus, 2P = Pe^(0.07t)

Dividing both sides by P results in 2 = e^(0.07t)

Take the natural log of both sides:  ln 2 = 0.07t.

Then t = elapsed time = ln 2

                                       --------- = 0.69315/0.07 = 9.9

                                         0.07

The doubling time of this investment would be 9.9 years.
