zubka84 [21]

Using the combination formula, it is found that she can shoot the ducks in 120 ways.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, 3 ducks will be shoot from a set of 10, hence:

$C_{10,3} = \frac{10!}{3!(10-3)!} = 120$

Thus, she can shoot the ducks in 120 ways.

A contractor charges $ 1,200 for 100 square feet of roofing installed. At this rate, how much does it cost to have 1,100 square

garik1379 [7]

For this problem we can use a proportion to solve.

Set up the proportion.

$\frac{1200}{100} = \frac{p}{1100}\\$

Cross multiply.

$1200 * 1100 = 100 * p\\1320000 = 100p$

Divide.

$\frac{1320000}{100} = \frac{100}{100}p\\13200 = p$

So, it would cost $13,200 to have a 1,100 square foot roof installed.
