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

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

Some help? Could you explain how to get \(41^{-3}\)?
[Fraction Form Please] :)
Answer:
Step-by-step explanation:
The negative power of the number should be 1 divided by the positive power of the number.
Which means \(41^{-3}\)\(=\frac{1}{41^{3} } =\frac{1}{68921}\)
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?
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.

w/6 +5/8=−1 3/8
Find w pls
Might give Brainliest
Answer:
w=-27/2
Step-by-step explanation:
Answer:
w = 4.5
Step-by-step explanation:
w/6 +5/8=−1 3/8
w/6 +5/8=−11/8
4w+15/24 = −11/8
4w+15 = 24(−11/8)
4w+15 = -264/8
4w+15 = 33
4w = 33 - 15
4w = 18
w =18/4
w = 4.5

SOMEONE WHO KNOWS THE AWNSER PLS HELP!
Step-by-step explanation:
Well, 6 away from 0 could be -1, -2, -3, -4, -5, -6, 1, 2, 3, 4, 5, 6. We include 6 and -6 because it says "no more than 6 units away" which means x≤6. So all you do is to use a segment that is shaded in on both sides from -6 to 6.

Mike has 40 baseball cards. Tim has 5 less than half of what Mike has. How many baseball cards does Time have?
Answer:
Give Branliest PLz
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.
please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.

The function for the points are y = -15x - 5
How to determine the functionFrom 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 pointsUsing (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
\(a=-15b-5\)

(5/2)² < 12.06 but
If y is supposed to be a factor, like multiply by 2, then
(5/2)²y > 12.06
Step-by-step explanation: substitute 2 for y
20y - 5² = 2
20(2) - 25 =
40 - 25 = 15
__________
(5/2)² = 5²/2²
25/4 = 6.25 . So that is less than 12.06
But if y is supposed to be a factor, like multiply by 2, then
(5/2)²y > 12.06

In a cheerleading competition, each team receives scores in eight categories. One team has an average score of 7.25 in the eight categories. 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.
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
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.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
Most populations, like the rabbit population represented here, are stable over time. In this model, we can imagine an increase in the death rate, followed by a decrease in the birth rate. What is another factor we could introduce to the model that would help to stabilize the rabbit population over time?
a. Introduce a predator to the area.
b. Climate change.
Answer: predator is a tiger
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.
