The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the number of sides.
40
What is the measure of an interior​ angle?

Answers

Answer 1

Answer:

The polygon has 9sides with an interior angle measure of 140°

Step-by-step explanation:

The exterior angle of a regular polygon=360°/n

40°=360°/n

n=360°/40°=9

So the polygon has 9 sides thus, a nonagon.

The measure of the interior angle=(n-2)180°/n

=(9-2)×180°/9=140°

The points (0,5) and (1,9) fall on a particular line. What is its equation in slope-intercept
form?

Answers

Answer:

y = 4x + 5

Step-by-step explanation:

First let's find its slope.

(5-9)/(0-1) = 4.

So far, in the equation we have y=4x+b.

As for the y-intercept, the coordinate (0,5) is the y-intercept.

Therefore, the equation in slope intercept form would be y=4x+5.

On a coordinate plane, the field is 1 unit up and 1 and one-half units to the left. The playground is 2 units to the left and 0.5 units down. The parking lot is 1 and one-half units to the right and 2 units up. The swimming pool is 1 and one-half units to the right and 1 unit up.

There are 96 girls and 72 boys who want to participate in 6th grade intramurals .If each team has the same number of girls and the same number of boys,How many boys and girls will be on each team?

Answers

Answer:

by taking Hcf of 96 and 72 we get 4 so each team have 4

'24' teams can be made with each team having 4 girls and 3 boys.

Given that,

No. of girls = 96

No. of boys = 72

Since the number of teams is not given, we will find by finding out the GCF(Greatest Common factor) of 96 and 72.

96 = 2 * 2 * 2 * 2 * 2 * 3

72 = 2 * 2 * 2 * 3 * 3

GCF = 2 * 2 * 2 * 3 = 24

Thus, a maximum of 24 teams can be formed. The number of girls and boys in each of these teams would be:

No. of girls in each team = Total girls/no. of teams

= 96/24

= 4 girls

No. of boys in each team = Total boys/no. of teams

= 72/24

= 3 boys

Thus, each team will have 4 girls and 3 boys.
