Answer:
31 hours
Step-by-step explanation:
First you take 313.50 divide that by 15 get 20.9 per hour
Then you take 647.90 and divide that by 20.9
So then you're left with 31 as your answer.

a plumber who is just starting out offers low rates to attract new customers. He charges $35
to visit a client's home, plus an additional $20 per hour.
Write an equation that shows how the cost of a visit, y, depends on its duration in hours, X.
Answer:
y=20x+35
Step-by-step explanation:
if a plumber who is just starting out offers low rates to attract new customers. He charges $35 to visit a client's home, plus an additional $20 per hour. Then y=20x+35 is equation that shows how the cost of a visit, y, depends on its duration in hours, X.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that
a plumber who is just starting out offers low rates to attract new customers
Plumber charges $35 to visit a client's home, plus an additional $20 per hour.
Let the charges per hour be denoted by x.
and it is given that y is cost of a visit.
We are required to write equation for cost of a visit y.
y equal to twenty x plus thirty five.
y=20x+35
Hence if a plumber who is just starting out offers low rates to attract new customers. He charges $35 to visit a client's home, plus an additional $20 per hour. Then y=20x+35 is equation that shows how the cost of a visit, y, depends on its duration in hours, X.

At his birthday party, John's mother served a plate of 23 cupcakes. If every person at the party ate the same amount of cupcakes and all of the cupcakes were eaten, how many people
were at John's birthday party?
A) 23
B) 12
C) 6
D) 4
Answer:
A) 23
Step-by-step explanation:
Let's divide the total number of cupcakes by the different option choices, and see what works and what doesn't:
A) 23/ 23 = 1
This works, everyone will get one cupcake
B) 23 / 12 ≈ 1.91666667
This doesn't work, we have a decimal / remainder, and you normally would not split 2/3s of a cupcake with someone at a party
C) 23 / 6 ≈ 3.8333334
This doesn't work, we have a decimal / remainder, and you normally would not split 2/3s of a cupcake with someone at a party
D) 23 / 12 ≈ 5.75
This doesn't work, we have a decimal / remainder, while this is a nicer remainder, it still is incorrect

What is the sum because I’m very slow
First, chance the fractions so the denominators are the same. The GCF of these is 10, so multiple both numerators and denominators so the denominator is 10.
1/2 = 5/10
3/5 = 6/10
Add the wholes and the fractions:
5 11/10
Since the numerator is higher than the denominator, we can make another whole:
11/10 - 10/10 = 1/10
So 5 becomes 6 because of the whole:
5 + 1 = 6
The fraction becomes 1/10:
So the final answer is:
6 1/10
(Important Note: Unless asked, you must always put fractions into its smallest form, meaning numerator can NEVER be higher than the demoninator. When you do this process, do not forget to add the whole number or else you will be incorrect.)
(Second note: its not GCF its closest product they have.)
Answer:
6 1/10
Step-by-step explanation:
convert mixed fraction to improper fraction
4 1/2 + 1 3/5
= (4*2 + 1) / 2 + (1*5 + 3) / 5
= 9/2 + 8/5
= lcm of 2 and 5 = 10
= (5 * 9 + 8 * 2) /10
= (45 + 16) /10
= 61/10
= (60 + 1) / 10
= 6 1/10

what will be the percentage for this
Answer:
84%
Step-by-step explanation:
To find a percentage, just divide the first number by the second.
[tex]\frac{193}{240}=0.80417[/tex]
So 193 is about 80% of 240.
If you were to do it in the other order:
[tex]\frac{240}{193} =1.24352[/tex]
240 is 124% of 193.
If x = 5, find the value of
a) x2
b) (x + 3)^2.
the 2 is meant to be squared
Answer:
a)since x=5
x²= 5×5
=25
b)(x+3)²
x=5
5+3=8
8²=8×8
=64
Soo :
a) x² = 5² = 5•5 = 25
b) (x + 3)² = (5 + 3)² = 8² = 8•8 = 64
find the volume of the prism
Answer:
96ft^3 (The third option)
Step-by-step explanation:
The volume of a prism is derived by the formula length*width*height. This is also known as the base*height. The base here is 6*4, but since it's a triangle, we divide by 2 to get 12 as the base. the height is 8, so 12*8=96 ft^3. Hope this helps!

2. Yes, is a function {(0, 3),(3, 5),(5, 6),(8, 4)}

4. No, not a function {(3, 4),(5, 2),(5, 6),(7, 3)}
Step-by-step explanation:
1. Since there is one value of y for every value of x in {(2, 2),(4, 4),(6, 6),(8, 8)} , this relation is a function.
2. Since there is one value of y for every value of x in {(0, 3),(3, 5),(5, 6),(8, 4)}, this relation is a function.
3. Since there is one value of y for every value of x in {(1, 2),(3, 3),(4, 8),(6, 3)}, this relation is a function.
4. Since x=5 produces y=2 and y=6, the relation {(3, 4),(5, 2),(5, 6),(7, 3)}, is not a function.

On Monday, Anya read 11 pages of a book in 1 2 hour. On Tuesday, she read 18 pages in 3 4 hour. Did Anya's reading speed increase by more than 10% from Monday to Tuesday? Complete the justification for your answer.
Answer:
The way you should go about solving this really depends on how your teacher taught you...However, here's what I would recommend...
You know that 1/2 an hour is equal to 30 minutes, and 3/4 of an hour is equal to 45 minutes.
Using this you can then solve for how many pages she read per minute by dividing the number of pages read by the number of minutes read:11 pages/ 30 minutes to give you Monday's reading speed,and18 pages/ 45 minutes to give you Tuesday's reading speed.
Next, to calculate a percentage increase you need to do the following:
1. Determine the difference between the speeds (this means you will subtract Monday's reading speed from Tuesday's reading speed.)
2. Next you take that number and divide it by Monday's reading speed.
3. Multiply that answer by 100 to get the percentage.
I'm not going to tell you the speeds, as you should try to attempt to solve it by yourself, and I'm sure you need to show your work. I will however tell you that you should find there was a 3.3% increase from Monday to Tuesday.

The width of the rectangle is equal to the greatest common monomial factor of 55x^655x 6 55, x, start superscript, 6, end superscript and 22x^422x 4 22, x, start superscript, 4, end superscript. What is the length and width of the rectangle?
Answer: I had difficulty reading the problem, so please check my interpretation.
Width is 11x^4 and Length is 5x^2 + 2
Step-by-step explanation:
Area of rectangle is 55x^6+22x^4Width is equal to the GCF of 55x^6 and 22x^4The greatest common factor of 55x^6 and 22x^4 is 11x^4. So the width is 11x^4.
Length = (55x^6+22x^4)/(11x^4)
Length = 5x^2 + 2

Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 min. Work out the difference between their average speeds in km/h. 1 mile = 1.6 km
Answer:
30.4 km/h
Step-by-step explanation:
Ajoba: 45 miles = 72 km ; 2.5 hours
Prav: 74 km ; 1 hour 15 min = [tex]\frac{5}{4}[/tex] hours
Ajoba's average speed: 72 ÷ 2.5 = 28.8 km/h
Prav's average speed: 74 ÷ [tex]\frac{5}{4}[/tex] = 59.2 km/h
Difference: 59.2 - 28.8 = 30.4 km/h
Suppose you want a guitar. It costs $756. About how much would you have to save every month for 6 months to be able to buy the guitar? i assume $126?
Answer:
$126 is correct
Step-by-step explanation:
Answer:
$126/month
Step-by-step explanation:
Divide the total cost ($756) by 6 (months). We get $126/month. Six months' payment (6 times $126) will produce a total savings of $756.
