Niall owes $187 to his cousin. However, he doesn't have any money right now. He hopes to earn some money by painting a house. He gets paid $34 for every 2 hours he paints. Which equation of a line models y, the amount of money he will have after paying back his cousin, in terms of x, the number of hours he spends painting?
Answer:
[tex]y=17x-187[/tex] where x>11
Step-by-step explanation:
Niall gets $34 for 2 hours.
So, he gets [tex]34/2=17[/tex] dollars per hour.
Now he owes $187 to his cousin.
Let the number of hours he works be = x
Let the money left with him after paying his cousin be = y
So, the equation forms:
[tex]y=17x-187[/tex]
Rather we can say it is :
[tex]y=17x-187[/tex] where x>11
If we want to know how many hours are needed to pay the debt, we can consider y = 0
[tex]17x-187=0[/tex]
[tex]17x=187[/tex]
[tex]x=187/17[/tex]
So, x = 11 hours
He needs 11 hours of work to pay back his cousin and after that all his earnings is 'y'. When x>11 then 'y' will have some money left.

a store marks up sporting goods 27%. write an expression that equals the retail price of an item with an original cost of p dollars?
The expression that equals the retail price of an item with an original cost of p dollars is option D: [tex]\( p \times 1.27 \)[/tex].
The retail price of an item with an original cost of p dollars is obtained by adding the markup percentage to the original cost.
Given that the store marks up sporting goods by 27%, the markup percentage is 27% of the original cost.
So, to find the retail price, we add the markup to the original cost:
[tex]\[ \text{Retail Price} = \text{Original Cost} + \text{Markup} \][/tex]
[tex]\[ \text{Retail Price} = p + 0.27p \][/tex]
[tex]\[ \text{Retail Price} = p \times (1 + 0.27) \][/tex]
[tex]\[ \text{Retail Price} = p \times 1.27 \][/tex]
So, the expression that equals the retail price of an item with an original cost of p dollars is option D: [tex]\( p \times 1.27 \)[/tex].
The probable question maybe:
A store marks up sporting goods 27%. Which expression equals the retail price of an item with an original cost of p dollars?
A p × 0.27
B p ÷ 0.27
C p × 0.73
D p × 1.27
Mr.Dixon bought a whiteboard that was on sale for 1,989.99. The regular was 2,499.89. Which is the best estimate of the amount of money Mr. Dixon saved by buying the whiteboard on sale?
Mr. Dixon saved approximately $509.90 by buying the whiteboard on sale, calculated by subtracting the sale price from the regular price.
To estimate the amount of money Mr. Dixon saved by buying the whiteboard on sale, you subtract the sale price from the regular price. The regular price was $2,499.89, and the sale price was $1,989.99. So, the estimated savings would be:
Regular Price - Sale Price = Savings
$2,499.89 - $1,989.99 = $509.90
Therefore, the best estimate of the amount Mr. Dixon saved is $509.90.
A certain shade of green paint requires 4 parts blue to 5 parts yellow. If you mix 16 quarts of blue paint with 25 quarts of yellow paint, will you get the desired shade of green?
The ratio of blue to yellow paint should be 4:5 to get the desired shade of green. Mixing 16 quarts of blue paint with 25 quarts of yellow does not meet this ratio; thus the exact shade will not be achieved.
Explanation:The subject of the question is Mathematics, and it involves the concept of ratios and proportions to achieve a desired color mix. To determine whether mixing 16 quarts of blue paint with 25 quarts of yellow paint will produce the desired shade of green, we must ensure that the ratio of blue to yellow in the mixture is the same as the required ratio. The desired ratio is 4 parts blue to 5 parts yellow. Simplifying this ratio, we have 4/5, which means that for every 4 units of blue, there should be 5 units of yellow.
Illustrating this with an equation:
(16 quarts blue) / (25 quarts yellow) = 4/5?
Reducing the given amounts,
16/25 = ? 4/5
Now, the simplified form of 16/25 is 16/25 itself, while 4/5 is equivalent to 0.8. Since 16/25 is not equivalent to 4/5, the mixture of 16 quarts of blue paint and 25 quarts of yellow paint will not give us the exact desired shade of green. Therefore, to get the precise shade, an adjustment in paint quantities to reflect the 4:5 ratio would be needed.
No, the desired shade of green will not be achieved with the given mixture of blue and yellow paint.
Explanation:To determine if you will get the desired shade of green, we need to compare the ratio of blue to yellow in the desired shade with the ratio of blue to yellow in the mixture. The desired shade requires a ratio of 4 parts blue to 5 parts yellow. The mixture has a ratio of 16 parts blue to 25 parts yellow. To compare the ratios, we can simplify them. The desired shade ratio simplifies to 4:5, and the mixture ratio simplifies to 16:25. Since these ratios are not equivalent, the mixture will not result in the desired shade of green.
Are these ratios proportional? 2 : 3 = 9 : 6

5/8 of the 64 musicians in a music contest are guitarists. Some of the guitarists play jazz solos, and the rest classic solos. The ratio of the number of guitarists playing jazz solos to the total number of guitarists in the contest is 1:4. How many guitarists play classical solos in the contest?
Out of the 64 musicians, 40 are guitarists, and the ratio of jazz to classical guitarists is 1:4. There are 10 jazz guitarists, and by subtracting this from the total, it's found that 30 guitarists play classical solos.
To determine how many guitarists play classical solos in the music contest, we first find out the total number of guitarists.
Since 5/8 of the 64 musicians are guitarists, we multiply 5/8 by 64 to get the number of guitarists, which is 40.
Knowing that the ratio of guitarists playing jazz solos to the total number of guitarists is 1:4, we can say that for every 4 guitarists, 1 plays jazz solos.
Therefore, if we divide the total number of guitarists, 40, by 4, we will find out how many play jazz solos:
40 / 4 = 10.
The rest of the guitarists play classical solos, which is computed by subtracting the number of jazz soloists from the total number of guitarists:
= 40 - 10 = 30.
So, 30 guitarists play classical solos in the contest.

The drop in temperature from 6:00A.M to 12:00 PM was 14 degrees Fahrenheit. What was the average hourly drop in temperature for that time frame
There was a 2.3° Fahrenheit average hourly drop in temperature for that time frame.
What is unit rate?A unit rate is defined as a ratio that compares the first quantity to one unit of the second quantity. The two quantities being compared have different units.
Given that, the drop in temperature from 6:00 A.M to 12:00 PM was 14 degrees Fahrenheit.
We need to determine the average hourly drop in temperature for that time frame,
So, the numbers of the hour from 6:00 A.M to 12:00 PM = 12-6 = 6 hours
Therefore, there was a fall of 14° Fahrenheit in 6 hours,
i.e. 6 hours = 14° Fahrenheit
So, 1 hour = (14/6)° Fahrenheit
= 2.3° Fahrenheit
Hence, there was a 2.3° Fahrenheit average hourly drop in temperature for that time frame.

Molly read 75 pages of the latest thriller mystery novel in 45 minutes. What is her unit rate? At the same rate, how long will it take her to read the entire 425-page novel?
Molly reads at a unit rate of 1.67 pages per minute, and it would take her approximately 255 minutes to read a 425-page novel at this rate.
Explanation:The student's question is asking for a calculation of a unit rate, which in this context is the number of pages read per minute, and then an estimation of time needed to read the entire novel based on that rate. To find Molly's unit rate, we divide the number of pages she read (75) by the time in minutes (45).
Unit Rate = Total Pages Read / Total Time (in minutes)
= 75 pages / 45 minutes
= 1.67 pages per minute
Next, to figure out how long it will take Molly to read the entire 425-page novel at the same rate, we use the following formula:
Total Time = Total Pages / Pages Per Minute
= 425 pages / 1.67 pages per minute
= 254.49 minutes
Since it's not usual to read for a fraction of a minute, we round up to the nearest whole number, which means it would take Molly approximately 255 minutes to read the novel.
Molly's unit rate is 1.67 pages per minute. By using this rate, it will take her approximately 254.5 minutes to read the entire 425-page novel.
Explanation:Molly read 75 pages of the latest thriller mystery novel in 45 minutes. Her unit rate of reading is the number of pages read per minute, which can be calculated by dividing the number of pages (75) by the number of minutes (45). To find out how long it will take her to read the entire 425-page novel, we can use the unit rate.
To calculate Molly's unit rate, we divide 75 pages by 45 minutes which gives us a unit rate of 1.67 pages per minute.
Next, to determine how long it will take Molly to read the entire novel, we divide the total number of pages in the novel (425) by Molly's reading speed (1.67 pages per minute). This calculation will give us the total time in minutes, which we can then convert into hours if needed.
Calculate the unit rate: 75 pages / 45 minutes = 1.67 pages per minute.Calculate the time to read the entire novel: 425 pages / 1.67 pages per minute = approximately 254.5 minutes.

A 3,780
B 3,840
C 4,780
D 4,840
The answer is A: 3,780.
To find the quotient of 56,700 ÷ 15, we need to perform the division step-by-step:
First, set up the division problem: 56,700 ÷ 15.Divide the first two digits, 56, by 15. The closest is 3, so put a 3 above the line:3 × 15 = 45; subtracting 56 - 45 = 11.Bring down the next digit, 7, making it 117. Divide 117/ 15 = 7, so put a 7 above the line:7 × 15 = 105; subtracting 117 - 105 = 12.Finally, bring down the last digit, 0, making it 120. Divide 120/15 = 8 times:8 × 15 = 120; subtracting 120 - 120 = 0.Therefore, the quotient of 56,700 ÷ 15 is 3,780 which corresponds to option A.
