Answer:

8 cup of blue

12 cup of red

Step-by-step explanation:

The first thing is to calculate how much black paint is produced, assuming that the volumes add up, we have to:

1/2 + 1/3 = 5/6

5/6 cup of paint is produced, I want to know how much I need to produce 20 cups, I divide the value I want by the ideal value, that is, 5/6 and thus I obtain the factor that I require:

20 / (5/6) = 24

Now I multiply by 24 each quantity of blue and red paint

1/2 * 24 = 12

1/3 * 24 = 8

Which means you need 12 cups of red paint and 8 cups of blue paint

bixtya [17]
For this case, the first thing we must do is define a variable.
 We have then:
 x: number of gift boxes.
 We then have to write the inequation that models the problem:
 "Mary bought more than 72 pencils"
 "she packs 4 pencils each into x gift boxes"
 We have then:
 4x \geq 72
 Simplifying we have:
 x \geq 72/4
 x \geq 18
 Answer:
 
the inequality that represents this situation is:
 4x \geq 72
 The simplified form of the inequality is:
 
x  \geq 18

Start with the standard formula for the area of a triangle, and rewrite it to solve for the base, b.
solong [7]

Answer:

2A/h = b

Step-by-step explanation:

The formula for area of a triangle is

A = 1/2 bh

Multiply each side by 2

2A = 2*1/2 bh

2A = bh

Divide each side by h

2A/h = bh/h

2A/h = b

How to put percent into decimal
fiasKO [112]

Answer:

There are multiple ways to do so:

You can divide the number by 100 to convert it to a decimal

You could take your percentage and add a decimal two places to the left.

Examples of both:

For division its as simple as 75 divided by 100 = 0.75

If we are going to use the decimal method, lets say we have 45%, so we can do this:

45% =45.00

Move the decimal two places to the left.

0.45
