Answer:
The number of full hours he must babysit to reach his goal of $200 is 5 hours
Step-by-step explanation:
Let x be the no. of hours he must babysit to reach his goal of $200.
Cost for working 1 hour at coffee shop = $11
Cost for working 15 hour at coffee shop = [tex]11 \times 15=165[/tex]
Cost for working 1 hour babysitting = $8
Cost for working x hour babysitting = 8x
We are supposed to find the number of full hours he must babysit to reach his goal of $200.
165+8x=200
8x=200-165
[tex]x=\frac{200-165}{8}[/tex]
x=4.375
Hence The number of full hours he must babysit to reach his goal of $200 is 5 hours

cross multiply so it becomes 8x=18 then divide both sides by 8 and x= 2 2/8
Step-by-step explanation:
(-7x + 6) - (-2x + 9x - 2)
Answer:
-14x+4
Step-by-step explanation:
So the first set of paranthese don't really matter so you can rewrite it to this
-7+6-(-2x+9x-2)
Then infront of the ( there is a - which means a -1. Now just do the disbutive property.
-7x+6+2x-9x+2
Now add like terms and you get your finial answer!
-14x+4
-2 1/3 - (-5) = ?

If there are 4 ships at a port and the first one leaves and comes back every three weeks, the second one every nine weeks, the third one every 12 weeks, and the fourth every 24 weeks when will they all be in the port at the same time/when will they be there all at the same week
Answer: After 72 weeks they will be in the port at the same time.
Step-by-step explanation:
Given, Total ships = 4
The first one leaves and comes back every 3 weeks, the second one every 9 weeks, the third one every 12 weeks, and the fourth every 24 weeks .
So, the number of weeks they will take to be in the port at the same time = L.C.M. (3, 9, 12 , 24) (L.C.M. = least common multiple)
Since, 9= 3 x 3
12 = 2 x2 x 3
24 = 2 x 2x 2 x3
then, L.C.M. (3, 9, 12 , 24)= 2 x 2x 2 x 3 x3 =72
Hence after 72 weeks they will be in the port at the same time.

Sanjay consulted three electricians about upgrading the wiring in his home. Each electrician uses a linear formula that incorporates a flat base fee and an hourly rate to determine the cost of service. Those formulas are shown in the table.
Repair Cost Formulas
Electrician
Cost in y dollars for an x-hour service
1
y = 25 x + 30
2
y = 30 x + 25
3
y = 25 x + 20
Which statement is best supported by the table?
Each electrician charges a different hourly rate.
Each electrician charges a different base fee.
All three electricians charge the same hourly rate.
All three electricians charge the same base fee.
Answer: B: each electrician charges a different base fee
Step-by-step explanation:
Answer:
b.Each electrician charges a different base fee:
Explanation:
Each of the equations has two parts:
1- base fee that is independent of any variable (this would be the number that has no variable next to it)
2- an hourly rate depending on the number of hours x (this would be the number that has an x next to it)
For the first electrician:
y = 25x + 30
base fee = $30
hourly rate = $25
For the second electrician:
y = 30x + 25
base fee = $25
hourly rate = $30
For the third electrician:
y = 25x + 20
base fee = $20
hourly rate = $25
Now, let's check the choices:
a.Each electrician charges a different hourly rate:
This is incorrect as electricians 1 and 3 charge the same hourly rate ($25)
b.Each electrician charges a different base fee:
This is correct as all three base fees are different ($30, $20 and $25)
c.All three electricians charge the same hourly rate:
This is incorrect as electrician 2 has a different hourly rate
d. All three electricians charge the same base fee:
This is incorrect as the base fees for the three electricians are different ($30, $25 and $20)

Jenna feeds her cat twice a day. She gives her cat 3/4 can of cat food each time. Jenna is having a friend take care of her cat for 5 days. To prepare, she bought 8 cans of cat food, did Jenna buy enough cat food?
Answer:
Number of times Jenna feeds her cat = 2
Cat food each time
Number of days = 5
Number of cans she bought = 8
Step-by-step explanation:
Required food for each time
Jenna feeds her cat twice a day
Required food for a day
Required food for 5 days
Since, 7.5 cans < 8 cans, therefore, Jenna did buy enough cat food for her cat.

One crate can store 12^3 toys. A warehouse receives 12^7 toys. Enter the number of crates
needed to store all the toys the warehouse received.
Answer: The number of crates needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]
Step-by-step explanation:
Given: Total number of toys = [tex]12^7[/tex]
Number of toys in one crate = [tex]12^3[/tex]
The number of crates needed to store all the toys the warehouse received.
= (Total number of toys) ÷ (Number of toys in one crate)
[tex]=12^7\div 12^3 = 12^{7-3}\ \ \ [a^m\div a^n=a^{m-n}]\\\\=12^4[/tex]
Hence, the number of crates needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]
Answer:
12^4 or 20736
Step-by-step explanation:
Since the warehouse has 12^7 toys and you need to find how much crates that can fit 12^3 toys will store all the toys, you must divide 12^7 by 12^3.
When dividing radical expressions, remember:
a^3/a^2=a^1 This kind of acts like subtracting the squared number
a^3 * a^2 = a^5 This kind of acts like adding the squared number
(a^3)^2 = a^6 This kind of acts like multiplying the squared number
Therefore, if you use the methods above, 12^7 / 12^3 = 12^4
12^4= 20736

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3). What is the coordinates of the image if the parallelogram is dilated with a scale factor of -1/3
Answer: [tex](\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .[/tex]
Step-by-step explanation:
Transformation rule for dilation:
[tex](x,y)\to(kx,ky)[/tex] , where k = scale factor
Given : Scale factor = [tex]-\dfrac13[/tex]
Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3)
Vertices after dilation:
[tex](-1,6)\to(-1\times\dfrac{-1}{3},6\times\dfrac{-1}{3})=(\dfrac13,-2)[/tex]
[tex](0,9)\times(0\times-\dfrac13,9\times-\dfrac13)=(0,-3)[/tex]
[tex](6,-3)\to(6\times-\dfrac13,\ -3\times-\dfrac13)=(-2,1)[/tex]
[tex](3,-3)\to (3\times-\dfrac13,\ -3\times-\dfrac13)=(-1,1)[/tex]
Hence, the coordinates of the image if the parallelogram = [tex](\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .[/tex]

Strip malls appear to popping up everywhere. The relationship between the actual price of a strip mall and the listing price is modeled in the least-squares regression line Ĉ = 0.2 + 1.011. Both amounts are in hundred-thousands of dollars. Let L represent the listing price and C represent the sales price. Which of the following is the best interpretation of the slope of the regression line?
A)For each hundred-thousand-dollar increase in the listing price, the sales price will increase by $1.01.
B)For each hundred-thousand-dollar increase in the listing price, the sales price will increase by $101,000,
C)For each hundred-thousand-dollar increase in the listing price, the sales price will decrease by $101,000.
D)For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $1.01.
E)For each hundred-thousand dollar increase in the listing price, the sales price is predicted to increase by $101,000.
Answer:
The correct option is;
E) For each hundred-thousand dollar increase in the listing price, the sales price is predicted to increase by $101,000
Step-by-step explanation:
Whereby the relationship between the actual price of a strip mall and the listing price is modeled according to the least squares regression line as follows;
C = 0.2 + 1.01·L
Where;
L = The listing price
C = The sales price
Where both amounts are in hundred-thousands of dollars;
Therefore, given that the slope is 1.01, we have that for an increase of $100,000 for the listing price, L, which is 1 unit increase the sale price increases as follows
C₁ = 0.2 + 1.01 × 1 = 1.21
While for an increase of an extra $100,000, to make the listing price. $200,000 or 2 units, we have;
C₂ = 0.2 + 1.01 × 2 = 2.22
The increase is C₂ - C₁ = 2.22 - 1.21 = 1.01
C₂ - C₁ = $100,000 × 1.01 = $101,000
The increase is C = $101,000
Whereby, the equation is a linear regression line which is a model for prediction, we have;
The predicted increase in the sale price is $101,000 for each $100,000 increase in the listing price.
