Work out the size of an exterior and an interior angle of a regular 16-sided
polygon.​

Answers

Answer 1

Answer:

exterior angle: 22.5°, interior angle: 157.5°

Step-by-step explanation:

the formula for the measure of each Interior Angle in a regular polygon: [tex]\frac{180(n-2)}{n}[/tex], n = # of sides

=> [tex]\frac{180(16 - 2)}{16}[/tex] = 157.5°

the formula for the measure of each Exterior Angle in a regular polygon: [tex]\frac{360}{n}[/tex]

=> [tex]\frac{360}{16}[/tex] = 22.5°

The base of the triangle is 4 inches more than the length of the sides and the total the total perimeter is 64 inches. Write an equation to find the length of each side of the triangle

Answers

Answer:

Both the sides are equal to 20 inches and the base is equal to 24 inches.

b=s3= s1+4----equation 1

s1=s2----equation 2

Perimeter of the triangle = s1+s2+s3--------equation 3

Step-by-step explanation:

Let the sides be denoted by s1 and s2 . Then the base is denoted by b=s3= s1+4----equation 1

According to the statement s1=s2----equation 2

Perimeter of the triangle = s1+s2+s3--------equation 3

   64= s1+s2+ s1+4

 64 = 3s1+4

60= 3s1

20 = s1

Both the sides are equal to 20 inches and the base is equal to 24 inches.

A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?

P=2500(0.25)^t

P=2500+0.25t

P=2500(0.75)^t

P=2500(1+0.25)^t

Answers

Answer:

P=2500(1+0.25)

Step-by-step explanation:

Given  data

Initial population= 2500

Rate= 25%

The exponential increase is described using the expression

P=A(1+r)^t

Hence the correct representation is

P=2500(1+0.25)

slove: 3/2 (x-6) = -3

The answer is x = 4

Step 1: Simplify both sides of the equation.

3 /2 (x−6)=−3

( 3 /2 )(x)+( 3 /2 )(−6)=−3(Distribute)

3 /2 x+−9=−3

3 /2 x−9=−3

Step 2: Add 9 to both sides.

3 /2 x−9+9=−3+9

3 /2 x=6

Step 3: Multiply both sides by 2/3.

( 2 /3 )*( 3 /2 x)=( 2 /3 )*(6)

What is the surface area of the rectangle below?

Answers

Step-by-step explanation:

First, we must take into account that there will be 3 pairs of sides that are the same. Starting at the front, we have 9 * 12. Since the rectangular prism is measured in units squared, this side is 108 units squared. The opposite side is the same. Our current total is 216 units. The side is 15 * 9. This is 135 units, multiplied by 2 since it has the other side, to get 270 units. Our current total is 486 units, so it already can't be A. The top and bottom sides are 15 * 12 units, giving us 180 on each, 360 in total. 360 plus 486 = 846 units squared.

You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example  the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.

C.

Answers

The answer is D i’m sure

The number of people who could be expected to buy a flag using the expression (22/200) x 25,000 is 2,750.

Option D is the correct answer.

We have,

Based on the table,

The number of people who could be expected to buy a flag out of 25,000 visitors is:

(22/total items sold) x 25,000

To find the total items sold, you can add up the number of caps, jerseys, flags, and programs:

Total items sold.

= 68 + 19 + 22 + 91

= 200

The number of people who could be expected to buy a flag is:

(22/200) x 25,000 = 2,750

Thus,

The number of people who could be expected to buy a flag is 2,750.
