Answer:
$50
Step-by-step explanation:
Step one:
charges per hour= $60
We are told that the electrician earned $350
for a job that took 5hours
The linear equation to represent his earnings is
let the flat fee be x
C=60t+x------------1
so for C=$350
Required
the flat fee
350=60(5)+x
350=300+x
collect like terms
x=350-300
x=50
Flat fee is $50
Answer: C=60t+50
Step-by-step explanation:
$60 an hour,
5 hours before the fixed fee is only $300
but the amount he made for a 5 hour house call was $350,
making the fixed fee $50

An equation of a line perpendicular to the line represented by the equation y = -
1/2 x - 5 and passing through (6,4) is what?
Answer:
y= 1/2x+1
Step-by-step explanation:
Answer:
[tex]y=2x-8[/tex]
Step-by-step explanation:
First, remember that perpendicular lines have opposite and reciprocal slopes to the original line. That means for this line, your slope will be 2 (flip the fraction and change the sign). So we have:
[tex]y=2x+b[/tex]
Next, plug in the point that it passes through in order to find the y-intercept (b).
[tex]4=2(6)+b[/tex]
[tex]4=12+b[/tex]
[tex]b=-8[/tex]
So your equation will be:
[tex]y=2x-8[/tex]

When dividing each of the numbers $$3759$$ and $$4139$$ by some positive integer number, the remainder happened to be equal to $$16$$. What is the smallest possible value of the divisor?
Answer:
The smallest possible value of the divisor is 19
Step-by-step explanation:
The given numbers for division are;
3759 and 4139, the remainder = 16
Let x represent the number
Therefore, we have;
x > 16
x is a factor of 3759 - 16 = 3743, and x is also a factor of 4139 - 16 = 4123
The factors of 3743 obtained from an online resource are 1, 19, 197, 3759
The factors of 4123 obtained from an online resource are 1, 7, 19, 31, 133, 217, 589, 4123
The common factors of 3743 and 4123 are 1, 19
Given that x > 16, we have, x = 19
Therefore, the smallest possible value that will divide both 3759 and 4139 whereby the remainder is 16 = 19

Step-by-step explanation:
Franklin school is having a Popsicle party for its nine hundred fifty four students.The secretary there will some Popsicle left over to share with the teachers. Each student will get two Popsicle. Popsicle come in boxes that have one dozen Popsicle. There are twenty-five boxes in cartoon, how many boxes of Popsicle? Show your work.
Answer:
175 boxes
Step-by-step explanation:
There are a total of 954 students since each student will get two popsicles that would mean we need a total of 1,908 popsicles (954 * 2). Since each box contains 12 popsicles then we simply divide the total number of popsicles needed by the number of popsicles that fit in each box to find the total number of boxes.
1,908 / 12 = 159 boxes
Since there are 25 boxes per carton we divide 159 by 25
159 / 25 = 6.36
Now we see that we need at least 6.36 cartons of popsicles, but since we can't get 6.36 we would need to get 7 cartons which would bring a total of
7 * 25 = 175 boxes
Finally, we would end up with 175 boxes of popsicles which would be enough for all the students and have leftover for the teachers.
The figure below is a square. If m2AEB = (5x + 15)°, what is the value of x?
Answer: x = 25
Step-by-step explanation: im pretty sure you would square 5 and get 25 then 15 and get 225, then you would divide those two numbers 225 and 25 and get 25

Which of the following equations represents the value of a savings account at the Owl Credit Union at Dundalk High School that has an initial
deposit of $250 and pays an annual interest rate of 2%?
Answer:
Step-by-step explanation:
Given
Initial deposit (Principal)= $250
Rate = 2%
Time = 1year (annual interest)
Required
Amount after 1 year
First we need to calculate interest
Interest = PRT/100
Interest = 250*2*1/100
Interest 2.5 * 2
Interest = $5.0
Next is to calculate amount;
Amount = Principal + Interest
Amount = $250 + $5
Amount = $255
Hence the value of a savings account at the Owl Credit Union at Dundalk High School that has an initial deposit of $250 and pays an annual interest rate of 2% is $255.
Amount = P + I
Value of savings account is $255
Simple Interest rate;Given that:
Initial deposit = $250
Annual interest rate = 2% = 0.02
Find:
Equations represents value of savings account
Computation:
Equations represents value of savings account = P + PRT
Equations represents value of savings account = 250 + (250)(0.02)(1)
Equations represents value of savings account = 250 + 5
Equations represents value of savings account = $255

A group of ‘n' friends decided to rent a condominium for a one week vacation in Florida. They decided to share the weekly rent of ‘m' dollars equally. If due to an unanticipated reason two members of the group couldn't make the trip, and the rest of the friends decided not to charge the two who pulled out for the rent; what will be the additional amount each of the remaining friends must pay for renting the condominium?
Answer:
2m / n² - 2n
Step-by-step explanation:
Given that:
Number of friends = n
Weekly rent = $m
To share rent fee equally :
Each friend will pay : $m / n
If 2 of the friend couldn't make the trip:
Additional amount to be shared by the others = 2(m/n) = 2m/n
Hence additional fee per friend who eventually made the trip:
Additional amount to be shared / number of friend who eventually made the trip
= (2m/n) ÷ (n - 2)
= 2m / n * 1 / n - 2
= 2m / n(n-2)
= 2m / n² - 2n
