Answer:

8 cups disinfectant per 36 gallons of water

Step-by-step explanation:

Yes, set up an equation of ratios:

 2/3 cup disinfectant          3 gallons water        1

--------------------------------  =  -------------------------- = -----

                x                          36 gallons water      12

Cross multiplication yields  12(2/3 cup disinfectant) = 1x, so that:

x = 8 cups

8 cups of disinfectant are needed to make a solution involving 36 cups water.

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenths place.
luda_lava [24]

Answer:

286.97

Step-by-step explanation:

find the area of the rectangle first

14*15=210

Next

Find the area of a circle

πr^2=a

the radius of the circle is half the height of the rectangle

π*(7*7)=a

a=153.94

Now

Divide the area by two

153.94/2=76.97

Now add the two areas

76.97+210

I need to know how to do Solving Systems of Equations by Elimination
vredina [299]
The point of elimination is to have one variable so example

3x + 2y = 4

7X + 3y = 5


1) Try to find a way to have one variable

7(3x + 2y = 4) ----> 21x + 14y = 28

-3(7x+ 3y = 5) -----> -21x -9y = -15


2) add

0 + 5y = 13

3) solve for the last variable

5y = 13
y = 13/5 = 2 3/5 = 2.8

4) Subsitute the variable to get the other one

3x + 2(2.8) = 4

3x + 5.6 = 4

3x = -1.6

x = 0.533333333 (continue)

The intersection would be 0.53 with a line above the 3 and 2.8. (0.5333 , 2.8)

Hope you understand!!
