A criminal has escaped in a train wreck. The police believe he could have traveled no more than 7 mi in any direction from the w

adelina 88 [10]

Answer:

A = 153.94 sq mi

Step-by-step explanation:

In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following

A = $\pi r^{2}$

A = $\pi 7^{2}$

A = $\pi 49$

A = 153.94 sq mi

A total of 153.94 square miles must be searched.

What annual rate of interest would you have to earn on an investment of $3500 to ensure receiving $273.00 interest after 1 year?

kogti [31]

To find the answer, we will have to find the percentage of $273 to $ 3500, and we can use the formula:

$\frac{interest received}{investment amount} \times 100%$

In this case:

273/3500 x 100%

=39/500 x 100%

=7.8%

Therefore the annual interest rate would be 7.8%.

Hope it helps!

you'll get a decimal format, just multiply it times 100, to get the % format
