Answer:

4.2 miles

Step-by-step explanation:

Martina runs 6 miles in 50 minutes, we have to find the rate at which she is running. Put it in a fraction $\frac{6}{50}$ or she runs 6 miles every 50 minutes. When we divide we get that she is running, 0.12 miles evrey minute. The question askes us how far Matina will run in 35 minutes, so we multiply 0.12 by 35, and we get that she will run 4.2 miles.

Answer:

$\$522.78$

Step-by-step explanation:

Let

x ---> the number of years

y ---> the amount in the account balance

Plan A

we have a linear equation of the form

$y=mx+b$

where

The slope is equal to

$m=\$100\ per\ year$

The y-intercept or initial value is

$b=\$500$

substitute

$y=100x+500$

For x=10 years

substitute

$y=100(10)+500=\$1,500$

Plan B

we have a exponential growth function of the form

$y=a(1+r)^x$

where

$a=\$500\\r=15\%=15/100=0.15$

substitute

$y=500(1+0.15)^x$

$y=500(1.15)^x$

For x=10 years

substitute

$y=500(1.15)^{10}=\$2,022.78$

Find the difference of the two account balances after 10 years

$\$2,022.78-\$1,500=\$522.78$

2,345 is 7% of 33,500 There are many sites that can show you how to get a percentage so I am going to move onward. You will add the seven percent on each year, like the following

First Year: 33,500
Second Year: 35,845 (+7%=2,345)
Third Year:38,354.15 (+7%=2509.15)
Forth Year: 41,038.94 (+7%=2684.79)
Fifth Year: 69,311.67 (+7%=2,872.75)

Sorry for wait.

Answer:

x = 79

Step-by-step explanation:

This is an isosecles triangle so the bottom angles have equal measure

and since the sum of interior angles in a triangle is equal to 180

2x + 32 = 180 subtract 32 from both sides

2x = 158 divide both sides by 2

x = 79
