Step-by-step explanation:
Susan wants to hire one of two mechanics to repair her car. Each mechanic charges a one-time fee in
addition to an hourly rate.
Mechanic A charges a one-time fee plus $35 per hour. A repair made by Mechanic A that takes 5 hours to
complete will cost a total of $225.
This table shows the total cost, including the one-time fee, for repairs made by Mechanic B that take
different numbers of hours to complete
Mechanic B
Time
(hours)
Total Cost
(dollars)
1
80
2.
120
3
160
4.
200
5
240
6
280
How much more money in dollars does Mechanic A charge for the one-time fee than Mechanic B
charges?
there no table showing mechanic b. but mechanic a charges a one time fee of $50
35 an hour times 5 hours is 175
the total of 225 -175= $50 as a one time fee

A sunflower grew 7 yards during the first week after it was planted. What is the height of the total sunflower in feet?
Answer:
21 feet
Step-by-step explanation:
Remember to get feet to yards, multiply the feet by 3 because there are 3 feet in one yard
in this case 7 × 3 = 21
And additionally to get yards to feet, divide by three because 1 yard = 3 feet

Answer:
10 pieces with 8" left over
Step-by-step explanation:
[tex]8 \div \frac{3}{4} = 8 \times \frac{4}{3} = \frac{32}{3} = 10 \frac{2}{3} [/tex]
so there's 10 pieces and 2/3 of a leftover piece.
2/3 of a foot is
[tex] \frac{2}{3} (12) = 8[/tex]
so there are 8" left

Answer:
18 cm^3
Step-by-step explanation:
To find the volume, count the number of cubes, since each cube has a side length of 1 cm
The volume of 1 cube is 1*1*1 = 1 cm^3
There are 6 rows of 3 cubes each or 18 cubes
18 cubes of 1 cm^3 = 18 cm^3
Answer: 18 cubic cm
Step-by-step explanation:

?????????????????????????????????????????/
Answer:
Your value of z is 71 degrees. The value of x is 11.
Step-by-step explanation:
You can determine the value of z by knowing that z and the 71 angle are vertical angles. Vertical angles are congruent to each other. We know that the x angle and the 71 angle are supplementary, or that they equal 180. So, set up the equations, and solve for x. :
[tex]180=71+(9x+10)\\180=81+9x\\99=9x\\x=11\\[/tex]

Javier and his family drove to see Javier's grandparents during summer vacation in 2006. Gas prices varied from place to place. The gas prices Javier saw advertised advertised during the trip are shown below. What is the difference between the mean and median gas prices in dollars?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required data to calculate the mean and the median are missing.
To solve this, I will assume the following values:
[tex]13, 18, 13, 14, 13, 16, 14, 21, 13[/tex]
[tex]n = 9[/tex]
The mean is calculated as:
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]Mean = \frac{13+ 18+ 13+ 14+ 13+ 16+ 14+ 21+ 13}{9}[/tex]
[tex]Mean = \frac{135}{9}[/tex]
[tex]Mean = 15[/tex]
To calculate the median;
Start by sorting the data
[tex]Sorted: 13, 13, 13, 13, 14, 14, 16, 18, 21[/tex]
[tex]n = 9[/tex]
The median is:
[tex]Median = \frac{n + 1}{2}[/tex]
[tex]Median = \frac{9 + 1}{2}[/tex]
[tex]Median = \frac{10}{2}[/tex]
[tex]Median = 5th[/tex]
The median is the 5th item on the list; i.e. 14
So:
[tex]Median = 14[/tex]
The difference (d) between the mean and the median is:
[tex]d = |Mean - Median|[/tex]
[tex]d = |15 -14|[/tex]
[tex]d = |1|[/tex]
Remove absolute bracket
[tex]d=1[/tex]
The difference in the mean and the median of the assumed dataset is 1
A triangle PQR is right angled at R, with PQ=80cm and R=60cm. find QR?
Step by step PLS PYTHAGORUS THEOREM
Answer:
Solution given:
A triangle PQR is right angled at R, with hypotenuse{h}PQ=80cm
and
base[b]PR=60cm.
perpendicular [P]= QR
by using Pythagoras law
h²=p²+b²
80²=QR²+60²
QR²=80²-60²
QR=[tex]\sqrt{2800}[/tex]
QR=20[tex]\sqrt{7}[/tex]=52.9=53cm
QR=53cm.
There are 29 students in Mrs. Dixon's science class. On the last test, only 1 student earned the median score of 84.
How many students scored an 84 or lower?
A - 15
b - 14
C - 13
D - 12
Answer:
A
Step-by-step explanation:
Median can be described as the number that occurs at the middle of a set of observations.
for example, in the set of numbers, 1 2 3 4 5, the median is 3
median = (first number + last number) / 2
If there are 29 students,
median = (1 + 29) / 2 = 30/2 = 15
the 15th students scored 84
and students between 1 - 14 scored lower than 84
so, 15 students scored an 84 or lower

Calculate the volume of the composite solid.
Answer:
about 33.52 in^3
Step-by-step explanation:
Volume of composite figure = volume of cone + volume of hemisphere
Volume of a cone = 1/3(nr^2h)
n = 3.14
r = radius
h = height
1/3 x 3.14 x 2^2 x 4 = 16.74 inches^3
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 3.14
r = radius
2/3 x 3.14 x 2^3 = 16.74 inches^3
16.74 inches^3 + 16.74 inches^3 = 33.49
