The ratio of one triangle to the other (because they are similar, since the top angles are both 44 degrees and the two sides on the other sides of them are the same) is 12:8, or 3:2.

So therefore, we can say it's 9:6, so DE is 6.

Compute the total cost per year of the following pair of expenses. Then complete the sentence: On an annual basis, the first s

algol13

Answer:

$\text{Total cost per year}=\$2244$

On an annual basis, the first set of expenses is 53.28% of the second set of expenses.

Step-by-step explanation:

We are asked to find the total cost per year of the following pair of expenses.

Maria spends $15 on lottery tickets every week and spends $122 per month on food.

To find the annual total cost per year, we will multiply weekly cost of lottery by 52 as a year has 52 weeks.

$\text{Annual cost of lottery}=\$15\times 52$

$\text{Annual cost of lottery}=\$780$

$\text{Annual cost of food}=\$122\times 12$

$\text{Annual cost of food}=\$1464$

$\text{Total cost per year}=\$1464+\$780$

$\text{Total cost per year}=\$2244$

Therefore, the total cost per year of the given pair of expenses is $2244.

Now, we need to find 780 is what percent of 1464.

$\frac{780}{1464}\times 100$

$0.532786885\times 100$

$53.2786885\%\approx 53.28\%$

Therefore, on an annual basis, the first set of expenses is 53.28% of the second set of expenses.
