Answer: 80 ounces of yellow paint

Working:
As we know 2 ounces of yellow paint to 5 ounces of red paint, we can make a ratio:

2:5

Then we look at the question which says 200 ounces of red paint, so we replace the 5 ounces of red paint in the ratio with 200.

2:200

Then we figure out how much the 5 has been multiplied by to get to 200. We do this by doing

200 divide 5 = 40

Therefore we times the 2 ounces of yellow paint by 40 which gets us:

80:200

We can think of it as a fraction too to confirm our answer:

Simplify 80 / 200

We get 2 / 5.

If you need me to further explain something please just ask :)

What is 1/2 divided by 1/3
Artemon [7]

Answer:

\frac{3}{2}

Step-by-step explanation:

\frac{1}{2} ÷ \frac{1}{3}

The reciprocal of  \frac{1}{3} is 3, so finding the reciprocal will replace the division sign with a multiplication sign.

= \frac{1}{2} x 3

= \frac{3}{2} or 1\frac{1}{2} or 1.5

Find the slope of the given line, if it is defined. 2x + 1 = 0
svlad2 [7]

Given :

A line 2x + 1 =0 .

To Find :

The slope of the given line .

Solution :

We know , slope of line is given by the tangent of the angle between the x-axis and the line .

Now, for line 2x + 1 =0 i.e x=\dfrac{-1}{2} .

The line is perpendicular to x-axis and cuts the x-axis at \dfrac{-1}{2} .

Therefore , the angle between the line and x-axis is 90^o .

So , slope m=\tan\ 90^o i.e undefined .

Therefore , the slope of given line is not defined .

Hence , this is the required solution .
