4 0

Answer: 0.8 or 80%

Step-by-step explanation:

First find the total number of marbles:

10 + 15 + 25 = 50 marbles total

To find the number of marbles that are not black:

15 + 25 = 40 marbles that are not black

Set up ratio:

\frac{40}{50} = 0.8 or 80%

How can parallel lines be used to compare figures E and F? Explain your reasoning.
Aneli [31]

Answer:

The similarities are

1) The length of E and F can be described by two parallel lines spaced 3 blocks apart where the parallel line on the left of both E and F is 2 blocks long, while the parallel line on the right is one block long

2) Both height of E and F can be described by two parallel lines spaced 2 blocks apart  where the parallel line on the top of both E and F is 3 blocks long, while the parallel line at the bottom is one block long

3) The interior of E an F can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion

The differences are

1) The difference between E and F is that the parallel lines used for the construction of E are all one block higher than that of F

2) The other difference is that all the lines used for the construction of the figure E are 3 blocks to the left of those used for the construction of F

Figure F is essentially the translation of figure E three blocks to right and one block down

The circle above has an area of 144 pi cm^2. What is the area of the blue sector? Use 3.14 for pi.
sineoko [7]

Answer:

150.72 cm^2

Step-by-step explanation:

The blue area has an angle of 120 degrees, and 120/360 = 1/3, which shows that the blue area is 1/3 of the circle. In that case, the blue area is just 144pi/3. That simplifies to 48 pi.

48*3.14 = 150.72
