Cee-Lo Green decided to paint his entire house purple! The purple paint mixture contains 1/2
Temka [501]

Answer

Find out the how many cups of red and blue paint would you  need .

To prove

As given

Cee-Lo Green decided to paint his entire house purple .

The purple paint mixture contains \frac{1}{2}cup of blue paint and  \frac{1}{3} cup of red paint.

Thus the ratio of the blue paint to the red paint is given by.

\frac{Blue\ paint}{Red\ paint} = \frac{\frac{1}{2}}{\frac{1}{3}}

Thus

\frac{Blue\ paint}{Red\ paint} = \frac{3}{2}

As given

same ratio to make 20 cups of purple paint .

Let us assume that the x be the scalar multiple of the blue and the red paint.

Blue paint cups = 3x

Red paint cups = 2x

2x + 3x = 20

5x = 20

x = \frac{20}{5}

x = 4

Thus

Blue paint cups = 3 × 4

                        = 12 cups

Red paint cups = 2 × 4

                        = 8 cups

Therefore  8 cups of red and 12 cupsblue paint would you  need to form 20 cups of the purple paint.

Dan and Paul went shopping at a department store
soldier1979 [14.2K]

Answer:

D  4+p=24

Step-by-step explanation:

So P stands for Paul & how much he spent.

Dan spent $24 at the store & he spent $4 more than Paul, so Paul only spent $20.  So P = $20

So which equation would work if you substituted $20 for P?

4 + P = 24

4 + 20 = 24

Set the x as the different numbers that appear in the set

Set the y as the frequency of each number.

b: 2 fish has the highest frequency.

c: Add the terms. 97 is the total fish been bought

2.

a: When making the stem and leaf plot, do it in this format

1| 7,4,3,5,8,4

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

a: Find the frequency of each bar and add them.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.
