Answer 1

Answer:

Answer:

Pool A.

Step-by-step explanation:

This can be solved through ratios. You would write it as $(gallons)/(minutes)$ So, $(2/3)/(15)$ for the first one, and $(2/3)/(20)$ for the second. You might want to use a calculator for that part, but you could also change the gallons to cups, which gives you a much better number of 10.515. So, $(10.515)/(15) = 0.701$ , and $(10.515)/(20) = 0.52575$ So, pool A is at a faster rate. If you want it in gallons per minute, it's by 0.01 (with the 1 repeating) gallons per minute. By cups, it's 0.17525 cups per minute.

(The reason I did not do this by cross multiplying and dividing ratios is because it gives you the exact same answer if you are finding it per one, as I am here with per one minute. You can do it this way, it just wastes a bit of time.)

Answers

20 kg bag of bananas for 10 dollarsThis is the given situation in which in every 20 kilogram of bananas, the costs is 10 dollars.Now, let us calculate how much each kg of banana costs will. Let’s solve for the unit rate of this given data:=> 20 kg bag of banana=> 10 dollars = costNow, let’s divide this to get the answer that we need.=> 20 / 10=> 2 bananas per dollars = 2 banana/dollarsOr 10 / 20=> 0.5 dollars/1kg of banana

A circle with diameter 11 inches.What is the approximate area of the circle? Use 3.14 for Pi and round the answer to the nearest tenth.

Answers

Answer:

a=95.0 in^2

Step-by-step explanation:

The area of a circle is:

a= $\pi$ r^2

First, we must find the radius

r=d/2

r=11/2

r=5.5

Substitute 5.5 in for r in the formula

a= $\pi$ 5.5^2

a= $\pi$ 30.25

Substitute 3.14 in for pi

a=3.14*30.25

a=94.985

Rounded to the nearest tenth:

a=95.0 in^2

Hope this helps! :)

Find the area of the following shape.

Please explain how you broke it up and did

Answers

See attached image.

I broke it up into 4 different shapes, 3 triangles and a square.

Area for a triangle is 1/2 x base x height:

Triangle 1: 1/2 x 4 x 3 = 6

Triangle 2: 1/2 x 6 x 3 = 9

Triangle 3: 1/2 x 1 x 6 = 3

Area of square = S^2 = 6^2 = 36

Total area = 36 + 6 + 9+3 = 54 square units

Draw a segment from point E to point B. Now you have a triangle above with base FB of length 10 and height EA of length 3, and a trapezoid below with bases DC of length 7 and EB of length 6 and height CB of length 6.

area of figure = area of triangle + area of trapezoid

area of figure = bh/2 + (b + b)h/2

area of figure = 10(3)/2 + (7 + 6)(6)/2

area of figure = 15 + 39

area of figure = 54
