In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the polygon have?
Answer:
15 sides
Step-by-step explanation:
Always the sum of interior angle and exterior angle = 180
Let the exterior angle = x
Interior angle = 6.5 *x = 6.5x
x + 6.5x = 180
7.5x = 180
x = 180/7.5
x = 24
Exterior angle = 24°
Sum of exterior angles of any polygon = 360
number of side = Sum of exterior angles ÷ measure of each exterior angle
= 360 ÷ 24
= 15
What is the area of the composite figure?
Answer: 126 in
Step-by-step explanation: 126 in because if you were to seperate the shapes you would get 6 in for the triangle by using the formula A=1/2 bh and for the rectangle you would get 120 by using the formula A=bh and when you add it you will get 126 in.
Answer: 126 in.

Which is the simplified form of the expression m + 3m + 2 + 2?
Answer:
If you want to factor it, it will be 4(m+1).If not factored, it will be 4m+4
Step-by-step explanation:
m+3m+2+2
m+3m = 4m
2+2 = 4
4m+4
To factor that, you can take out 4 as a common factor, so it will be (4)(m+1)
Answer:
4m+4

Evaluate the expression y2 when y=2.5
Answer:
5
Step-by-step explanation:
if u wouldnt mind giving me brainliest, just tryna rank up
The value of the expression at y = 2.5 is 6.25.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
y²
Substitute y = 2.5
= y²
= 2.5²
= 2.5 x 2.5
= 6.25
Thus,
The value is 6.25.

Solve for a:
a – 17 = -15
A. a = -32
B. a = 2
C. a = 32
D. a = 12
Answer:
B
Step-by-step explanation:
a-17=-15
so the whole point of solving problems like this is to get the variable on one side (a in this case) and the constants on the other side (-17 and -15 in this case).
so to get rid of the 17 because its negative you have to add 17 or do the inverse sign but whatever you do to on side you have to do to the other side so you add 17 to both side
-17+17 they cancel out
-15+17=2
so now we get that a=2
your answer would be B
hope this helps :D

Step-by-step explanation:
Over the course of a year, a classroom went from 15 students to 19 students.
Use the drop-down menus to build an equation that could be used to find the percent change, p, in the number of students.
Answer:
26.7%
Step-by-step explanation:
The positive change from 15 to 19 is 4.
Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:
4/15 = 0.26667
Multiplied by 100%, 0.26667 becomes 26.7%: the percentage change in the number of students

I need the thing for the square pizza ill give brainlest to who gets its right
Answer:
A) The square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.
B) There's more crust on the square pizza then on the circle one, according to 60>50!
Step-by-step explanation:
A)First, let's calculate the area of the round pizza.
We need to find out the radius, and radius=[tex]\frac{diameter}{2}[/tex]
So radius=16/2, which is 8.
And a circle's area is [tex]\pi r^{2}[/tex], so the equation for this round pizza is:
[tex]\pi (8)^{2}[/tex]
=64[tex]\pi[/tex]
≅201 [tex]inch^{2}[/tex]
Second, we calculate the square pizza's area, which is pretty easy since the equation for a square is: [tex](Side Length)^{2}[/tex].
So for this square pizza, the area would be:
[tex](15)^{2}[/tex]
=225 [tex]inch^{2}[/tex]
Lastly, we compare the two, 225>201, so the square pizza gives you more delicious (XD) pizza. And 24 (225-201) more pizza.
B)So this problem is actually asking you to find the circumference of the circle and perimeter of the square.
Let's start off with the circle, the formula for circumference is:
[tex]\pi (d)[/tex]
We already have the d, (diameter), which is 16, so the circumference of this circle pizza is:
16[tex]\pi[/tex]
≅50 inch
Then we find the a square's, the equation for perimeter is:
4 (side length)
=4(15)
=60 inch
So happily, we found out there's more crust on the square pizza then on the circle one, according to 60>50!
