Find the number of sides a polygon has if the sum of the measures of its interior angles is four times the sum of the measures o

vfiekz [6]

Answer:

the polygon has 10 sides

Step-by-step explanation:

Recall that the sum of the interior angles of a polygon of N sides is given by the formula:

Sum = (N - 2) * 180

and that the sum of the exterior angles of any polygon is always 360 degrees.

Since we are told that the sum of the interior angles is 4 times the sum of the exterior angles, we set the following equation:

(N - 2) * 180 = 4 * 360

Solving for N, we start by dividing both sides by 180:

(N- 2) = 4 * 360 / 180

N - 2 =4 * 2

N - 2 = 8

N = 10

So the polygon has 10 sides

Degger [83]

Answer:

The total price of $4\frac{1}{2}$ pounds of apples is $6.48.

Step-by-step explanation:

Given:

Last week,the price of apples at a grocery store was 1.60 per pound.This week,apples at the same grocery store are on sale for a 10% discount.

Now, to find the total price of 4 1/2 pounds of apples this week at the grocery store.

The price of apples at a grocery store last week was = $1.60 per pound.

This week apples at the same grocery store is on sale of 10% discount.

Thus, the price of apples at a grocery store this week is:

$1.60-10\%\ of\ 1.60.$

$=1.60-\frac{10}{100} \times 1.60$

$=1.60-0.16$

$=\$1.44.$

So, the price of apples per pound this week is $1.44.

Now, to get the total price of $4\frac{1}{2}$ pounds of apples by using unitary method:

If 1 pound of apples cost = $1.44.$

Then, $\frac{9}{2}$ pound of apples cost = $1.44\times \frac{9}{2}$

$=1.44\times 4.5$

$=\$6.48.$

Therefore, the total price of $4\frac{1}{2}$ pounds of apples is $6.48.
