The number of days for which the money is left to reach the 20,400$ mark is; 21.28 days

<h3>Compound interest</h3>

The final amount to be reached is; $20400

The principal amount is; $8,000 and at. rate of 4.75 % compounded.

Hence, it follows that;

  • 20400 = 8000(1+0.045)^(x)

Divide both sides of the equation by 8000; we have;

  • 20400/8000= 1.045^(x)

  • 2.55 = 1.045^(x)

Take log of both sides;

  • x = 0.4065/0.0191

  • x = 21.28 days.

Dante runs 7 miles in 60 minutes. At the same rate, how many miles would he run in 24 minutes?
denis23 [38]
<h2>Answer: 2.8 miles</h2>

Step-by-step:

We can write it in the proportion \frac{7}{60} = \frac{x}{24}

where x is our number of miles trying to find

We now cross multiply or use the butterfly method which I will demonstrate both

<h3>Cross Multiply</h3>

We multiply the numerator with the dominator

so 7 multiplied by 24

and 60 multiplied by x

7*24=60x

168=60x

\frac{168}{60} =\frac{60x}{60}

2.8=x or x=2.8

Now for the

<h3>Butterfly Method </h3>

You would do 7 times 24 divided by 60 or \frac{7*24}{60}

Then\frac{168}{60} simplify

2.8 so 2.8 miles in either method
