Answer:

If Ike runs at the same pace for 53 minutes, he will run approximately 16.9 miles.

Step-by-step explanation:

By creating a ratio of miles over time, you can get this

(7)/(22)=(x)/(53) = 16.86 -> 16.9

Answer:

Approximately 16.86 miles

Step-by-step explanation:

We can use ratios to solve

7 miles x miles

------------ = -------------------

22 minutes 53 minutes

Using cross products

7 * 53 = 22x

371= 22x

Divide each side by 22

371/22 = 22x/2

16.8636363 = x

Answer:

The equation would be:

3x + 2 = 7*2

Step 1. Subtract 2 from both sides:

3x = 6*2

Step 2. Divide both sides by 3:

3x/3 = 6*2/3
x = 2*2

A single box weights x= 4 units.

Anna has a 30-year, 5.75% mortgage on her $250,000 home. She has been

poizon [28]

Answer:

Her new monthly payment is now $1,378.91¢

Step-by-step explanation:

For us to calculate the new monthly mortgage payment that Anna will start paying from now on, we need to input the formula for calculating monthly mortgage payments.

The formula is:-

$M = P [\frac{r(1+r)^{n} }{(1+r)^{n}-1}]$

Where M is the monthly mortgage payment.

P is the principal

r is the monthly interest rate calculated by dividing your annual interest rate by 12

n is the number of payments(the number of months you will be paying the loan).

In this case, the new principal that Anna must pay back is $231,905.47¢. The annual interest rate has been reduced to 5.17% from 5.75% so the new monthly interest rate will be obtained by dividing the new annual interest rate by 12

= 5.17%/2

= 0.431%

This is the new monthly interest rate.

Since she has been paying her mortgage loan diligently for 5 complete years. It means she now has just 25 years to complete the payment. If 12 months make up one year, then there are - 12 × 25 = 300 more months to go.

300 is therefore "n" that is required for the calculation.

All the terms needed for the calculation of her new monthly mortgage is now complete.

P = $231,905.47¢

r = 0.431%

n = 300

$M = 231,905.47[\frac{0.00431(1+0.00431)^{300} }{(1+0.00431)^{300} -1}]$

$= 231,905.47[\frac{0.00431(3.634)}{2.634}]$

= 231,905.47 × 0.005946

M = $1,378.91¢

Therefore her new monthly mortgage payment will become $1,378.91¢
