<span>1/6 of 54 = 9 and 1/3 of 21 = 7
<span>so, 1/3 of 21 is smaller than 1/6 of 54.
Hope this helps :) </span></span>
You calculate the number of ways that 2 people can be chosen from 10.
The formula:
n! / r! * (n-r)! =
10! / 2! * 8! =
10 * 9 * 8! / 2 * 8! =
10 * 9 / 2 =

<span> If all numbers are greater than zero and no repeated numbers exist these are the 5 possible combinations:
1 + 2 + 8
1 + 3 + 7
1 + 4 + 6
2 + 3 + 6
2 + 4 + 5.

The equations are:
1. 2.35y = 4.70
2. k/3 = 17
3. 4 = 10w
4. 55x = 111
5. 8 = a/5
Answer:
the equations that apply are:
1. 2.35y = 4.70
3. 4 = 10w
4. 55x = 111
Step-by-step explanation:
We want to determine which if the equation we can use the division property of equality to solve.
1. 2.35y = 4.70
We can divide both sides by 2.35, so that
2.35y/2.35 = 4.70/2.35
y = 4.70/2.35
THIS WORKS
2. k/3 = 17
THIA DOESN'T WORK
3. 4 = 10w
dividing both sides by 10
4/10 = 10w/10
w = 4/10
THIS WORKS
4. 55x = 111
Divide both sides by 55
55x/55 = 111/55
x = 111/55
THIS WORKS
5. 8 = a/5
THIS DOESNT WORK

Answer:
3 times the smaller triangle base
Step-by-step explanation:
The volume is proportional to the height and to the area of the base.
If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.
Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.
