Ms groves had trays of paint each tray has five colors one of the colors is purple.what fraction of the colors in 20 trays is purple

Answers

The correct answer is:
(4)/(20) = (1)/(5).

Explanation:
Since 1 out of 5 trays are purple, this means the fraction is 
(1)/(5).
However, to find the number of trays out of 20, we multiply 20 by 
(1)/(5):
 20*(1)/(5)=(20)/(1) * (1)/(5) = (20)/(5) = 4.

Answer:

(1)/(5)

Step-by-step explanation:

Given : Ms groves had trays of paint each tray has five colors one of the colors is purple

To Find:. What fraction of the colors in 20 trays is purple

Solution:

Since each tray contains 5 colors

So, 20 tray contains no. of colors =  20*5

                                                          =100

Now we are also given that 1 out of five color is purple

So, each tray contain no. of purple color = 1

So, 20 tray contains purple color = 20*1 = 20

So, the fraction of the colors in 20 trays is purple :

=\frac{\text{No. of purple colors in 20 trays}}{\text{Total No. of colors in 20 trays}}

=(20)/(100)

=(1)/(5)

Thus the (1)/(5) fraction of the colors in 20 trays is purple

Write an equation in slope-intercept form of the line through point P(10, –9) with slope 3.

Answers

Answer:

y = 3x - 39

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the slope m = 3 and the point P(10, -9).

Pu the value of slope and the coordinates of the point (x = 10, y = -9) to the equation of a line:

-9=3(10)+b

-9=30+b           subtract 30 from both sides

-39=b\to b=-39

Finally:

y=3x-39

A rectangular prism 3 dimensions, and the volume of 576 inches

Answers

the volume is calculated multiplying the width, height, and length:
v = whl
as we do not have much information about all those three, I will assume that the prism is a cube, therefore all sides are equal, call them s, so the volume would be:
v = whl = s*s*s = s^3
and plug in the data:
v = 576 = s^3
s = 576^(1/3)
s = 8.32
therefore each side of the cubic prism would have a length of 8.32 inches

1. Maritza is baking cookies to bring to school and share with her friends on her birthday. The recipe requires eggs for every cups of sugar. To have enough cookies for all of her friends, Maritza determined she would needeggs. If her mom bought cups of sugar, does Maritza have enough sugar to make the cookies? Why or why not?

Answers

Answer:

Maritza has not enough sugar to make the cookies.

Step-by-step explanation:

Missing data

The recipe requires 3 eggs for every 2 cups of sugar.

Maritza determined she would need 12 eggs.  

Her mom bought 6 cups of sugar.

Writing data as a proportion gives

(3 eggs)/(2 cups of sugar) = (12 eggs)/(x cups of sugar)

Omitting units

3/2 = 12/x

Multiplying by x in both sides

3/2 *x = 12

Dividing by 3 and multiplying by 2 on both sides

x = 12*2/3

x = 8 cups of sugar

So, 6 cups are not enough.

first we need to know how many kids how much eggs and sugar to answer this sorry

Solve the proportion 8/3=g/3 ... A.1/8 B.9/8 C.8 OR D.8/9

Answers

Answer:

g = 8.  (Answer C)

Step-by-step explanation:

We are given 8/3 = g/3.

If we multiply both sides by 3, this will eliminate the fractions, and we will be left with g = 8.  (Answer C).

Final answer:

The solution to the proportion 8/3 = g/3 is g = 8, corresponding to option C.

Explanation:

In this proportion, the value of g can be found by solving the equation 8/3 = g/3. Because both sides of the equation are divided by 3, the 3's essentially cancel each other out, leaving you with g = 8.

Therefore, the solution to the proportion 8/3 = g/3 is g = 8. So, the correct answer is C. 8.
