A. 6

There will be 6 layers of cubes, since the height is 3 centimeters and the height of the cubes is 1/2

B. 24

The perimeter is the formula 2l+ 2w. With the length and width being 8 and 4, you get 16+8 which is 24 for the perimeter of the base

A. There will be 6 layers of cubes because each cube has a height of 1/2 and 3x2=6

B. The perimeter of the base is 24cm.

2l+2w=p
2(8)+2(4)=p
16+8=p

Add. Simplify (or reduce) your answer, if necessary 1/4 +2/7+1/2=
Bumek [7]

Hey there! :)

Answer:

29/28.

Step-by-step explanation:

Starting with:

\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =

Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:

\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =

Add the fractions:

\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}

Therefore, the fractions sum up to 29/28.

Which is one way to check 102÷6 = 17? A) 105÷10 = 10 .5 B) 17÷6 = 102 C) 100÷5 = 20 D) 100×5 = 500
Karolina [17]
Was there a typo in the possible answers by any chance? B is closest to the possible answer, but only if the division sign was a multiplication sign.
102 <span>÷ 6 = 17
102 </span><span>÷ 17 = 6
17 x 6 = 102
6 x 17 = 102</span>

A cone with radius 2 and height 9 has its radius tripled. How many times greater is the volume of the larger cone than the small
SpyIntel [72]

Answer:

When increasing the radius 3 times the volume increases 9 times and when it is reduced to a third the volume decreases 9 times

Step-by-step explanation:

We have that the formula for the volume of a cone is:

Vc = pi * (r ^ 2) * h

We first calculate the original volume, where the radius is 2 and the height is 9, replacing:

Vc = 3.14 * (2 ^ 2) * 9

Vc = 113.04

Now if the radius is tripled it would be: 2 * 3 = 6, the radius would be 6, replacing:

Vc = 3.14 * (6 ^ 2) * 9

Vc = 1017.36

If we compare:

1017.36 / 113.04 = 9

This means that when the radius is tripled, the volume increases 9 times.

When if re reduces to a third the radius would be: 2/3, replacing:

Vc = 3.14 * ((2/3) ^ 2) * 9

Vc = 12.56

113.04 / 12.56 = 9

Which means that by reducing it to a third the volume becomes 9 times smaller.
