Amounts of paint left over are:

Yellow:  1 1/7 - 3/4 = 32/28 - 21/28 = 11/28 gallon

Green:  1 1/8 - 3/4 = 9/8 - 6/8 = 3/8 gallon

Blue:  7/8 - 3/4 = 7/8 - 6/8 = 1/8 gallon

Add 11/28 gallon, 3/8 gallon and 1/8 gallon to answer this question.

Answer:

Mark have left  \frac{11}{28} gallon yellow paint,  \frac{3}{8} gallon green paint and  \frac{1}{8} gallon blue paint.

Step-by-step explanation:

Mark wants to paint a mural.

Mark has yellow paints =  1\frac{1}{7} gallons

He has green paint =  1\frac{1}{8} gallons

quantity of blue paint =  \frac{7}{8} gallons

He plans to use  \frac{3}{4} gallon of each paint.

after painting mural, amount of yellow paint left = 1\frac{1}{7} -  \frac{3}{4} =  \frac{32-21}{28} = \frac{11}{28} gallon

Amount of green paint left =  1\frac{1}{8} -  \frac{3}{4} =  \frac{9-6}{8} =  \frac{3}{8} gallons

Amount of blue paint left =  \frac{7}{8} -  \frac{3}{4} =  \frac{7-6}{8} = \frac{1}{8} gallons

Mark have left  \frac{11}{28} yellow paint,  \frac{3}{8} of green paint and  \frac{1}{8} of blue paint.

Total amount of paint left =  \frac{11}{28} +  \frac{3}{8} +  \frac{1}{8} = \frac{25}{28}

The gas tank in felizs car is 5/6 full each time he drives to or from work he uses 1/12 of a full tank of gas which equation rep
Illusion [34]

Answer:

\frac{1}{12}x = \frac{5}{6}\\  \\

Step-by-step explanation:

<u>Given:</u>

  • Volume of fuel = 5/6
  • Volume of fuel used each time = 1/12
  • Number of travels to or from work = x

<u>Since each time 1/12 of the tank is used, and initial volume is 5/6 of the tank, the equation will be:</u>

  • \frac{1}{12}x = \frac{5}{6}\\  \\

<u>Solving the equation we get:</u>

  • x = \frac{5}{6}÷\frac{1}{12}
  • x = \frac{5}{6} × 12
  • x = 10

So Felitz can travel 10 times to/from work with 5/6 full tank

Right triangle XYZ has legs of length XY = 12 and YZ = 6. Point D is chosen at random within the triangle XYZ. What is the proba
Katen [24]

Answer:

5/9

Step-by-step explanation:

If you draw the triangle out on a grid papar and draw a line across the 2 marker point from XY up of the YZ side, you will see that the line from that marker point across to the hypotenuse is actually 8. Then you find the area of the little triangle with legs 8 and 4 (since 6-2 is 4), and the area is 16. After that, find the total area of the big triangle, which is 12x6/2=36. Since we want to know the area of the quadrilateral at the bottom of the big triangle seperated by the 2 marker point, we subtract 16 from 36, which equals to 20. 20/36=5/9. And that is my final answer. I tested it and it is correct. I hope this helps.
