Answer:

2167 meters squared

Step-by-step explanation:

First find the area of the square ice skating rink: 47^2 = 2209.

Then, find the area of the triangle without ice by using 1/2bh: (12/2)(7)=42.

Simply subtract the triangle's area from the squares for the final answer of 2167 meters squared.

Calculus. Find the area.
matrenka [14]

Answer:

8/3 square units.

Step-by-step explanation:

First, visualize the area. You can refer to the attachment below.

To find the area then, we will integrate y from x = 0 to x = 2. Therefore:

\displaystyle A=\int_0^2x^2\, dx

Integrate:

\displaystyle A=\frac{1}{3}x^3\Big|_{0}^2

Evaluate:

\displaystyle A=\frac{1}{3}[2^3-0^3]=\frac{1}{3}(8)=\frac{8}{3}

The area is 8/3 square units.

Betsy sells laptops at an electronics store. She earns $180 a week, plus $15 for every laptop she sells. Betsy needs to earn at
lukranit [14]

Answer:

15x + 180 ≥ 900

x ≥ 48

Step-by-step explanation:

x = amount of laptops needed to sell.

Equation:

15x + 180 ≥ 900

15x ≥ 720

x ≥ 48

Check:

15(48) + 180 = 900

720 + 180 = 900

900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).
