Angelina_Jolie [31]

Answer:

168.168 square inches

Step-by-step explanation:

Given data

From the question, we can deduce that the side of the square is 28in

Hence the area of the square is

Area= 28^2

Area= 784 square inches

Also, the diameter of the circle is 28 in

The radius = 14 in

Area of circle= πr^2

Area= 3.142*14^2

Area= 3.142* 196

Area= 615.832 square inches

Therefore the area of the shaded region is

= Area of Square - Area of Circle

= 784-615.832

=168.168 square inches

While evan and sam are fishing 12kms from shore, their boat springs a leak, and water comes in at a constant rate of 3 gallons p
aev [14]

Based on the calculations, the slowest rate is equal to 4 gallons per minute.

<u>Given the following data:</u>

  • Distance from shore = 12 km.
  • In-rate = 3 gallons per minute.
  • Rowing rate = 24 km per hour.

<h3>How to calculate the slowest rate.</h3>

Let's assume the boat would sink if it takes in more than 20 gallons of water.

<u>Conversion:</u>

  • 24 km/h to km/min = \frac{24 }{60} = 0.4 km/min.

Translating the word problem into an algebraic expression, we have;

\frac{12}{0.4} \times 3 - \frac{12}{0.4} \times x\geq 30\\\\\frac{36}{0.4}-\frac{12x}{0.4} \geq 30\\\\90-\frac{12x}{0.4} \geq 30\\\\\frac{12x}{0.4} \geq90+30\\\\\frac{12x}{0.4} \geq120\\\\12x \geq120 \times 0.4\\\\12x \geq 48\\\\x\geq 4

Therefore, the slowest rate is equal to 4 gallons per minute.
