Answers
Answer:
D
Step-by-step explanation:
So if Arturo's family hires 3 painters for $50 an hour each, how much do they spend?
X= Charge for number of number of hours
Now let's say that each of the painters worked only one hour each.
That would be take a long time to add up so you multiply.
$50 x 3
In other words it's $50 + $50 + $50.
$50 x 3 = $150
Now X stands for the amount of money paid to each artist. In this case, X= $50. So we already figured out X. X is $50. It is a mistake to add the X at the end of the answer because X is already there in a numerical form. So the answer is D, $150.
=================================================
Explanation:
One painter charges $50 an hour. If they work for x hours, then they charge a total of 50x dollars.
For instance, let's say the painter works for x = 7 hours. This means s/he charges 50*x = 50*7 = 350 dollars overall.
That's for one painter. If we involve 3 painters, then the total bill comes to 50x+50x+50x = 150x dollars
We could also say 3*50x = 150x, since 3*(cost of one painter) = total cost for three painters.
This is why choices A and B are the two answers.
Choice C would be the answer if you only hired one painter. But instead, you hired three of them, so we can rule out choice C.
Choice D only works if x = 1 is plugged into 150x to get 150*x = 150*1 = 150. However, you don't want to limit yourself to this x value only. It's better to stick with 150x instead to be more general. That way you can find the cost for say x = 2 hours which is 150*x = 150*2 = 300 dollars. I'll let you try other x values.

Honon spent 3 1/4 hours on homework while Sequoia spent 2 5/6 hours on homework. How much more time did Honon spend on homework than Sequoia
Answers
Answer:
5/12 hours
Step-by-step explanation:
Honon = 3 1/4 hours
Sequoia = 2 5/6 hours
How much more time did Honon spend on homework than Sequoia
= number of hours Honon spent - number of hours Sequoia spent
= 3 1/4 hours - 2 5/6 hours
= 13/4 - 17/6
= (39-34) /12
= 5/12 hours

Three game tickets and four ride tickets cost $39. Five ride tickets cost $15. All game tickets cost the same and all ride tickets cost the same. What is the ratio of the cost of a game ticket to the cost of a ride ticket?
Answers
Answer: 3:1
Step-by-step explanation:
Let the cost of a game ticket be g.
Let the cost of a ride ticket be r.
The information given can be formed into an equation which will be:
3g + 4r = 39
Since Five ride tickets cost $15, the cost of each ride ticket will be:
= $15/5
= $3.
Therefore, 3g + 4r = 39
We put the value of r = $3 into the equation
3g + 4(3) = 39
3g + 12 = 39
3g = 39 - 12
3g = 27
g = 27/3
g = 9
The cost of a game ticket is $9
The ratio of the cost of a game ticket to the cost of a ride ticket will be:
= 9/3
= 3/1
= 3:1
The ratio is 3:1
Adam is building a computer desk with a separate compartment for the computer. The compartment for the computer is a rectangular prism and will be 8019 cubic inches. The compartment will be 24 inches longer than it is wide and the height will be 18 inches greater than the width. Find the dimensions of the computer compartment.
Answers
Answer:
The width of the computer compartment is 9 inches
The length of the computer compartment is 33 inches
The height of the computer compartment is 27 inches
Step-by-step explanation:
The given data on the rectangular prism compartment are;
The volume of the rectangular prism, V = 8019 cubic inches
The length of the compartment, l = 24 inches + The width, w
The height of the compartment, h = 18 inches + The width, w
Therefore, we have;
l = 24 + w
h = 18 + w
V = l × h × w
∴ V = (24 + w) × (18 + w) × w = w³ + 42·w² + 432·w = 8019
w³ + 42·w² + 432·w - 8019 = 0
By graphing the above function with MS Excel, we have one of the solution is w = 9
∴ (w - 9) is a factor of w³ + 42·w² + 432·w - 8019 = 0
Dividing, we get;
w² + 51·w + 891
w³ + 42·w² + 432·w - 8019 = 0
w³ - 9·w²
51·w² - 459·w
891·w
891·w + 8019
0
Therefore,
w³ + 42·w² + 432·w - 8019 = 0
w³ + 42·w² + 432·w - 8019 = (x - 9)·(w² + 51·w + 891) = 0
The determinant of the factor, w² + 51·w + 891 = 51² - 4×1×891 = -963, therefore, the it has complex roots
Therefore, the real solution of (x - 9)·(w² + 51·w + 891) = 0 is w = 9
The width of the computer compartment, w = 9 inches
The length of the computer compartment, l = 24 inches + 9 inches = 33 inches
The height of the computer compartment, h = 18 inches + 9 inches = 27 inches.

In a child’s bank are 11 coins that have a value of $1.85. The coins are either quarters or dimes. How many coins are quarters?
Answers
Answer:
The child has 6 dimes and 5 quarters.
Step-by-step explanation:
Let q and d represent the number of quarters and of dimes respectively.
Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).
Multiply the 2nd equation by 100 to remove the decimal fractions:
25q + 10d = 185 (Equation C)
Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:
-10q - 10d = -110
25q + 10d = 185
--------------------------
15q = 75, and so q = 75/15 = 5.
According to Equation A, q + d = 11. Replacing q with 5, we get:
5 + d = 11, and so d = 6.
The child has 6 dimes and 5 quarters.
Answer: The amount of money in quarters is $1.75
Step-by-step explanation: There are 7 quarters. 25c+25c+25c+25c+25c+25c+25c=1.75

Answers
Answer:
The probability that both Jun and Deron get hired=0.2
Step-by-step explanation:
Let
A=Jun
B=Deron
We are given that
The probability that Jun gets the job, P(A)=0.7
The probability that Deron gets the job, P(B)=0.4
The probability that at least one of them gets hired, [tex]P(A\cup B)=0.9[/tex]
We have to find the probability that both Jun and Deron get hired.
We know that
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
Using the formula
[tex]0.9=0.7+0.4-P(A\cap B)[/tex]
[tex]P(A\cap B)=1.1-0.9[/tex]
[tex]P(A\cap B)=0.2[/tex]
Hence, the probability that both Jun and Deron get hired=0.2
