Answer:

First, we find how many red beads there are:

2 + 1 + 3 = 6

12 - 6 = 6

Red beads = 6

Now we add the red beads and the purple beads:

Purple beads = 3

Red beads = 6

3 + 6 = 9

9/12 = 3/4

Hope this helps!

Tom can paint a house in 10 hours. If Sally helps, it takes them 4 hours. Without help, how long would it take Sally to paint a
Romashka-Z-Leto [24]
To determine the number of hours it takes for sally to paint one house, we use relations from the problem statement above. We use the concept of rates and ratios. For Tom, he would take 10 hrs to finish one house. So, we assign his rate as 1/10. For Sally, she would take x hours to finish one house. So, we assign 1/x. When both of them works, it would take only 4 hours. So, we write the rate as 1/4. It should be that the sum of the individual rates is equal to the rate when both are working.

1/10 + 1/x = 1/4

Solve for x,
x = 6.67 hours

Answer:

\displaystyle V=16500\ m^3

Step-by-step explanation:

<u>Volume Of A Pyramid </u>

The volume of a pyramid is computed as one third of the product of the area of the base (B) by the height (H):

\displaystyle V=\frac{1}{3}BH

<em>The question doesn't ask for anything in particular, so I'm computing the volume of the solid shown in the image </em>

We have a rectangular base of dimensions 15m x 60 m. The area of the base is

B=(15m)(60m)=900m^2

We now calculate the volume, knowing the height is 55 m

\displaystyle V=\frac{1}{3}(900\ m^2)(55\ m)

\boxed{\displaystyle V=16500\ m^3}
