Answer:
Compare the constants of the two variables.
Changed at the same rate, or by the same factor, then they are directly proportional. For example, since the x-coordinates changed by a factor of 2 while the y-coordinates also changed by a factor of 2, the two variables are directly proportional.

The volleyball team is having a carwash fundraiser. The cost of each car wash is $5. They sold some season ticket packages, which brought in $1640. The goal of the team is to make at least $2000 from the combined totals of the two fund-raisers. How many cars must they wash in order to meet the team goal of $2000?
Answer:
They need to wash 72 cars
Step-by-step explanation:
2000 - 1640 = 360
360/5 = 72

what is 5 7/20 written as a decamal
Answer:
5 7/20 as a decimal is 5.35
Hope that helps. x
Answer:
Step-by-step explanation:
If your question has a big number 5 and a fraction 7/20, the 5 is going to be in the left side of the decimal, like 5.something ... the 7/20 is going to be the part on the right. If you're allowed to use a calculator just divide 7÷20 and that part goes on the right of the decimal. If you're not allowed to use a calculator then change 7/20 into something/100 ... 7/20× 5/5 gives you 35/100. That is the decimal part. It is written .35 So all together you get 5 7/20 is 5.35

Find the angle measure
<ABD and <EBC are equal to each other. In order to solve for the x value, set the equations equal to each other;
4x = 2x + 40,
x = 20
Based off what angle you are trying to find, you would plug x = 20 into the equation.
Solve the equation.

what is 5x to the power of 2 times 4x to the power of 3 divided by 4
Answer:
5x^5
Step-by-step explanation:
5x^2*4x^3/4
Divide
5x^2*1x^3
Multiply and Calculate
5x^5
answer: [tex]25x^{3}[/tex]
steps to solve:
→ let's write this out as an equation instead of in word form. 5x to the power of 2 times 4x to the power of 3 divided by 4 is [tex]\frac{5^{2} * 4x^{3}}{4}[/tex].
→ first, calculate the power of [tex]5x^{2}[/tex]. [tex]5x^{2} = 25[/tex], so now we have [tex]\frac{25^{2} * 4x^{3}}{4}[/tex]
→ now, multiply the monomials. [tex]25 * 4x^{3} = 100x^{3}[/tex].
→ [tex]\frac{100x^{3}}{4}[/tex]. we need to cross out the common factor, which is 4. 100 divided by 4 is 25. we're now left with [tex]25x^{3}[/tex].
so, [tex]25x^{3}[/tex] is the answer

5. Find the measure of angle BAC. Hint: What is the sum of the measures of the
vertex angles of the nine congruent isosceles triangles? (1 point)
HELP PLEASE!!!!!
The measure of angle BAC is 20 degrees
How to determine the measure of BAC?The angle on a straight line is 180 degrees.
There are 9 equal sections on the straight line.
This means that the measure of each section is:
Each section = 180/9
Evaluate
Each section = 20
So, we have:
BAC = 20 degrees
Hence, the measure of angle BAC is 20 degrees

Find the inequality represented by the graph.
Answer:
y ≤ -1/3x + 1
Step-by-step explanation:
find the slope and y-intercept and write equation in form of
y = mx + b; m = slope and b = y-intercept
if you start at (0,1) and move down and to the right to (3,0) you get a slope equal to -1/3
we can see by looking at the graph that the y-intercept is 1
therefore, y ≤ -1/3x + 1

The oxygen atoms in the thermosphere absorb high-energy solar radiation and convert it into heat energy.
true
false
Step-by-step explanation:
Nitrogen and oxygen absorb solar radiation and release thermal energy, which causes temperatures in the thermosphere to be 1000 °C or higher. When most people think of an area that has high temperatures, they think of a place that is very hot. Although the thermosphere has very high temperatures, it does not feel hot. The answer is true
Elena received a $30 gift for her birthday. She plans to use it to buy one or more books. Elena will have to pay 8% sales tax on the books and $1.50 bus fare to get to and from the shopping center. If c = the amount in dollars Elena spends on books, this situation can be represented by the inequality below.
1.08c + 1.5 ≤ 30
The cost of book has to be less than or equal to 26.39.
The amount of money Elena can buy has to be less than or equal to $30. Thus, the inequality sign to be used is the less than or equal to sign.
(1 + tax)cost of books + cost of bus fare ≤ value of the gift
1.08c + 1.5 ≤ 30
In order to determine the maximum cost of books, take the following steps:
Combine similar terms
1.08c ≤ 30 - 1.5
Add similar terms together
1.08c ≤ 28.50
Divide both sides of the equation by 1.08
c ≤ 28.50 / 1.08
c ≤ 26.39

Yes, it might be scary at first sight bexause of the square mark. But it is no more special than any other graph transformation. The sqare mark here nly indicates that this graph is a parabola, and the 6 inside shifts the graph (be careful, it is negative so it moves the graph to the RIGHT, by 6 -- the square mark doesnt apply to that).

A coordinate grid is shown below:
A coordinate grid from negative 2 to 0 to positive 2 is drawn. There are three grid lines between a whole unit on the grid.
Part A: Which point represents the origin? (2 points)
Part B: Starting from the origin, explain how to plot the following three points accurately:
(−1, 1)
(1, −1.5)
(2, fraction 1 over 4)
(8 points
Answer:
Part A: The origin would be (0, 0)
Part B:
(-1, 1) starting from the origin (0,0), would move left 1 on the x-axis then you would move up 1 on the y-axis
(1, -1.5) starting from the origin (0,0), you would move to the right 1 on the x-axis, then you would move down 1.5 on the y-axis
(2, 1/4) starting from the origin (0,0), you would move to the right 2 on the x-axis, then you would move up 1/4 (.25).
a) The origin would be (0, 0).
What are Coordinates?Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x axis (horizontal) and y axis (Verticle) are the two axes that make up a coordinate plane.
Given:
a) The origin would be (0, 0).
b) First, (-1, 1) move left 1 on the x-axis then you would move up 1 on the y-axis
Second, (1, -1.5) move to the right 1 on the x-axis, then move down 1.5 on the y-axis
Third, (2, 1/4) move to the right 2 on the x-axis, then move up 1/4 (.25).
