The external angle of a regular polygon is 200 . How many sides does it have ? What is the measure of each interior angle? What is the total measure of its angles.

Answers

Answer 1

Answer:

An 18 sided shape.

Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

16 over 27 sorry if i’m wrong.

Only 9 members of the math club showed up for yesterday's meeting. This is only 20% of the total amount of members. How many total number of members are in the math club?

Answers

The answer is 45

----------------------------------------------------------------------------------------------------------------

If you worked it out it would've been simple.

20x5=100.

9x5=45.

----------------------------------------------------------------------------------------------------------------

If you turn 20% into a decimal the it will become 20 itself then you can do 20x5 to get 100, then you can use the 9 and the 5 and multiply it together then your answer is 45.

Answer is 15

Step-by-step explanation:

Half of 40 is 20 cause 40/2=20

Five less than 20 is 20-5 which= 15

So ur answer is 15

Answer:

15

Step-by-step explanation:

1. We know that Mike has 40 baseball cards total. We know that Tim has 5 less than half of the cards that Mike has.

2. First, we need to divide 40 (Mike's total amount of baseball cards) by 2 or multiply that by 1/2. That gives us 20 baseball cards.

3. Tim has 5 less than half of Mike's deck (20 baseball cards) so we have to take away 5 more cards. 20 - 5 = 15. Tim has 15 baseball cards.

The function for the points are  y = -15x - 5

How to determine the function

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

m is the slope of the liney - y₁ and (x - x₁) are the points

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

to find the original price of p first determine the total change in prices: p increased by £12 and q decreased by £6 for a net difference of +£6. this means that if both items had started with the same price before the changes were made then they would still have this same starting price after (since it has gone up for one item and down for another).

next calculate what 5/4ths of this starting price is: (£6 * 5) / 4 = £7.50
then subtract this from 12 to get the original price of p: £12 - £7.50 = £4.50

Write a division equation in the "Show Your Work" box and then solve algebraically to find the team’s total score s. Place your final answer in the space provided.

Answers

The total teams score in competition are 58.

Based on the condition, the solution to find the total teams score:

- Given the identify of variables:

Mean Score: 7.25/team

Categories : 8

Total team score: s

- Formulated the variables become equation properly:

s = Mean score x Categories

s = 7.25 x 8

s = 58

- Hence, The total teams score in competition are 58.

Equation refers to a mathematical expression containing the equals sign. Algebra is frequently used in equations. In mathematics, algebra is employed when the exact value of a calculation cannot be determined.

An equation is merely a numerical statement that can substitute a variable for an unknown value. A variable is a letter that is used to represent an unknown value. It can be any letter, although the letter x is the most common.

All formulas are equations. Some equations are not formulas. Equations are intended to be solved for a certain variable.

The variable of this problem is mean score, categories and total score. From this variable, identify each function to find the equation then the result.

climate change is making the rabbit heat up

Step-by-step explanation:

Answer:

Step-by-step explanation:

Introducing a predator to the area would help to stabilize the rabbit population over time. As the predator hunts the rabbits, it would reduce the population, preventing it from growing too large and potentially causing overgrazing and resource depletion. This would lead to a more stable population over time. Climate change is unlikely to have a stabilizing effect on the population as it can have unpredictable and often negative impacts on ecosystems and their inhabitants.
