I got 75582.

Explanation:

First, group the 40 identical candies into 20 pairs. It doesn't matter how since the candies are identical. This grouping will ensure that any assigment will contain at least two candies.

Then think of the 20 groups a 20 beads on a string. We are looking to place 11 separators between them to obtain 12 segments, each with a varying number of beads between them. How many ways are there to place 11 separators to 19 potential spaces between beads? The asnwer is $n = {19\choose{11}}=75582$

Svetach [21]

Answer: it will take 2.33 hours for the snow fall in both of the towns be equal.

Step-by-step explanation:

Let x represent the number of hours that it will take for the snow fall in both of the towns be equal.

A town accumulated 2 inches of snow and the depth is increasing by 6 inches every hour. This means that in x hours, the depth of snow in the town would be

6x + 2

A nearby town has accumulated 9 inches of snow and the depth is increasing by 3 inches every hour. This means that in x hours, the depth of snow in the town would be

3x + 9

For the snow fall in both of the towns be equal, the number of hours would be

6x + 2 = 3x + 9

6x - 3x = 9 - 2

3x = 7

x = 7/3 = 2.33 hours

Answer:

4 $x^{6}$ $y^{7}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$

12 $x^{5}$ × $y^{3}$ × $\frac{1}{2}$ x x $\frac{2}{3}$ $y^{4}$

= 12 × $\frac{1}{2}$ × $\frac{2}{3}$ × $x^{(5+1)}$ × $y^{(3+4)}$

= 4 $x^{6}$ $y^{7}$

The regular price of a basketball was $29.50. The basketball was on sale for 22% off. How much was the discount?

Nimfa-mama [501]

First we divide it by 100 to get 1% of the original price, which is $0.295.
Then we multiply that by 22 to get 22% of the original price: $6.49.
The discount was $6.49, hope this helps!
