20. Steve has $30 and he earns $5 an hour parking cars. Write an equation to represent how much
money in dollars (m) Steve has after any number of hours parking cars (h). Then use the equation to
determine after how many hours of parking cars willSteve have $105. (Show your work)
Answer:
$30+m($5 x h)
he will be working for 21 h
Step-by-step explanation:
So, Steve has $30, so you want to add that amount to the amount he earn, which is $105.
$5 times 21 is $105
h = 21
but we still need for m but, we already have m
m = $105

The greatest growth was between years 3 and 4. The growth between those years was about 8%.
o The greatest growth was between years 1 and 2. The growth between those years was about 36%.
Answer:
The greatest growth was between years 1 and 2. The growth between those years was about 36%.
Step-by-step explanation:
Divide 19 by 14 to check, it gets you 1.357 which rounds to 1.36, or an increase of 36%
Garvin is painting the outside of the house. One can of paint will cover 2/9 of the house.Garvin has already used 4 can of paint . How much surface is already painted
Answer:
4 cans of paint will cover 8/9 of the surface
Step-by-step explanation:
One can of paint covers 2/9 of the house.
Garvin has used 4 of those cans.
To get the fraction of the whole surface that has been covered by those 4 cans of paint, we can multiply, following the logic below:
1 can of paint covers = 2/9 of the surface
4 cans of paint will cover = x of the surface
x = 4 X 2/9 = 8/9
Therefore, 4 cans of paint will cover 8/9 of the surface
Write the equation of the line that passes through the given points.
(15/8,0) and (17/8,1/2)
The equation of the line is _______.
Answer:
Step-by-step explanation:
Going from (15/8,0) to (17/8,1/2), we see that x (the 'run') increases by 2/8, or 1/4, and that y (the 'rise') increases by 1/2. Thus, the slope of this line through the given points is m = rise / run = (1/2) / (1/4) = 2.
Using the point-slope formula for the equation of a line, we obtain:
y - 0 = 2(x - 15/8), or
y = 2(x - 15/8) (simplest form), or
8y = 2x - 15/4, or
2x - 8y = 15/4, or
8x - 32y = 15
All of these are correct; they are 'equivalent.'

Answer: what’s the question?
Step-by-step explanation:
Carson is a high school student with two part-time jobs. He earns $6 per hour for babysitting, and he earns $8 per hour doing clerical work for his father's business. His goal is to earn at least $96 a week, but because of school, he does not want to work more than 15 hours each week. Suppose Carson worked as a babysitter for 5 hours one week. What is the minimum number of full hours he would need to work at his father's business to earn at lease $96 that week?
Step-by-step explanation:
Step one:
let the hours for babysitting be x
and the hours for doing clerical be y
we are told that Carson would like to earn $96 weekly
She babysits for $6 per hour
and earned $8 per hour doing clerical work
6x+8y=96---------------1
Carson cannot work more than a total of 15 hours per week
5x+y≤15-------------2
The system of equation for the situation is
6x+8y=96
5 x+y≤15
y=15-5 x
put y=15-5 x in eqn 1
6x+8(15-5 x)=96
6x+120-40x=96
collect like terms
6x-40x=96-120
-34x=-24
x=24/34
x=0.7
Approximately 1 hour babysitting
put x= 0.7 in 5x+y≤15
5(0.7)+y≤15
3.52+y≤15
y≤15-3.52
y=11.4

suppose a+b=10 and the value of a increases by 1. If the sum remains the same, what must happen to the value of b?
Answer:
[tex]b[/tex] decreases by [tex]1[/tex]
Step-by-step explanation:
If the value of [tex]a[/tex] increases by [tex]1[/tex] and the sum remains the same, then the value of [tex]b[/tex] decreases by [tex]1[/tex].
Example:
Suppose [tex]a=7[/tex] and [tex]b=3[/tex].
[tex]a+b = 10[/tex]
[tex]b = 10-a[/tex] (minus [tex]a[/tex] on both sides)
Now, let [tex]a = 8[/tex] ([tex]a[/tex] has increased by [tex]1[/tex]):
[tex]b = 10-8[/tex]
[tex]=2[/tex]
From the comparison of the previous value of [tex]b[/tex] to the current value of [tex]b[/tex], the value of [tex]b[/tex] has decreased by [tex]1[/tex].

The owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb. He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb. How many pounds of each should the owner use?
_ pounds of chocolate candies
Answer:
9 pounds of chocolate candies
6 pounds of sugar candies
Step-by-step explanation:
x + y = 15
y = 15 - x
(7x + 2y) / 15 = 5
7x + 2y = 15 * 5 = 75
7x + 2 * (15 - x) = 75
7x + 30 - 2x = 75
5x = 45
x = 9
15 - 9 = 6
y = 6
9 pounds of chocolate candies and 6 pounds of sugar candies
The owner should use 6 pounds of the chocolate candies, and the other 9 pounds of the sugar candies.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb.
He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb.
x + y = 15
y = 15 - x
(7x + 2y) / 15 = 5
7x + 2y = 15 x 5 = 75
7x + 2 (15 - x) = 75
7x + 30 - 2x = 75
5x = 45
x = 9
Now 15 - 9 = 6
y = 6
Threfore, we conclude that 9 pounds of chocolate candies and 6 pounds of sugar candies.

A local amusement park has 30 rides that park visitors can go on. The following table shows the relative frequency distribution for the number of rides that a park visitor will typically go on during one day at the park. The table also shows the deviation, or difference, from 21, the mean of the distribution. Number of rides and attractions 10 15 20 25 30 Deviation −11 −6 −1 4 9 Relative frequency 0.1 0.2 0.2 0.4 0.1 Which of the following is closest to the standard deviation of the distribution? 5.83 5.83 A 7.07 7.07 B 7.90 7.90 C 20 20 D 34
Answer:
5.83
Step-by-step explanation:
Find the mean:
10(.1) + 15(.2) + 20(.2) + 25(.4) + 3-).1)
u = 21
Find the standard deviation:
[tex]\sqrt{(10 -21)x^{2} (.1) + (15 -21)x^{2} (.2)+(20-21)x^{2} (.2)+(25-21)x^{2} (.4)+(30-21)x^{2} (.1)}[/tex]= 5.83
The standard deviation is of 5.83.
The expected value is given by each value multiplied by it's relative frequency, thus:
[tex]E(X) = 0.1(10) + 0.2(15) + 0.2(20) + 0.4(25) + 0.1(30) = 21[/tex]
The standard deviation is given by the square root of the sum of the difference squared of each value and the mean, multiplied by it's relative frequency.
Then:
[tex]\sqrt{V(X)} = \sqrt{0.1(10 - 21)^2 + 0.2(15 - 21)^2 + 0.2(20 - 21)^2 + 0.4(25 - 21)^2 + 0.1(30 - 21)^2} = 5.83[/tex]
The standard deviation is of 5.83.

Either Table A or Table B shows a proportional relationship.
Table A
x −2 −1 0 1
y 2 3 0 5
Table B
x −1 0 1 2
y −3 0 3 6
Plot the points from the table that shows a proportional relationship.
Answer:
the answer is table B
Step-by-step explanation:
Answer:
Table B shows a proportional relationship
Explanation:
In a proportional relationship two quantities vary directly with each other.
So,
y ∝ x
y = kx
Where, k is the constant of variation.
The ordered pairs of table A are (-2,2), (-1,3), (0,0) and (1,5).
From these ordered pairs we can conclude that the value of y-coordinate is not changing according to the x-coordinate because the values of x increased by 1 for each ordered pair but the value of y is not increasing in the same proportion..
The ordered pairs of table B are (-1,-3), (0,0), (1,3) and (2,6). The value of y increasing at a constant rate 3 and the value of y-coordinate is 3 times of x-coordinate.
Choose any two ordered pairs of table B. Let the two points are (0,0) and (1,3).
The proportional relationship is defined as
y = 3x
Therefore, 3 is the constant of variation and rate of change.
So, Table B shows a proportional relationship.
