So in total, there are 7 marbles, (3 black + 4 red = 7 total marbles) and we want to find out how much black marbles are able to come out. So it would be 3/7. :)

MatroZZZ [7]

Answer:

6

Step-by-step explanation:

We can use ratios to solve

15 ft            18ft

---------- = -----------

5ft               x

Using cross products

15x = 5*18

15x = 90

Divide by 15

15x/15 = 90/15

x =6

Piece made in 32min factory cut the time by 8% then cut time by 5% how long does it take to make the piece now in min
DiKsa [7]

Answer:

27.968 mins

Step-by-step explanation:

1) we need to find 8% of 32:

32*0.08=2.56

so 8% of 32 is 2.56 mins.

we need to subtract 2.56 by 32 since its says the times was cut by 8%

so

32-2.56=29.44

now 5% of 29.44:

29.44*0.05=1.472

1.472 mins

so

29.44-1.472=27.968

Hope this helps!

Other than itself, which angle is congruent to CBE?
jekas [21]

Answer:

<GBF

Step-by-step explanation:

<GBF is congruent to <CBE because they are vertical angles.

The vertical angle theorem states this is true.

Vertical angles are formed by a pair of intersecting lines and are the angles directly across from each other.

Since <GBF and <CBE are vertical angles, they are hence congruent.
