Mr. Barnes hired a plumber to fix a leak. The total cost, in dollars, that the plumber charges for a job can be modeled by the function
p() = 45 +35x, where x represents the time, in hours, that the plumber used to complete the job.
Mr. Barnes budgeted $220 to pay the plumber for the job.
After how many hours will the cost of the job exceed Mr. Barnes's budget?
Answer:
After 5 hours
Step-by-step explanation:
Given
[tex]p(x) = 45 + 35x[/tex]
Required
Determine what time the budget would exceed $220
To do this, we simply substitute 220 for p(x)
[tex]220 = 45 + 35x[/tex]
[tex]220 - 45 = 35x[/tex]
[tex]175= 35x[/tex]
Solve for x
[tex]x = 175/35[/tex]
[tex]x = 5[/tex]
So, Mr. Barnes would exceed his budget after 5 hours

The first step to change a fraction to a percent is to ...
A. Multiply the numerator by the denominator
B. Change the fraction to a decimal
C. Move the decimal point to the right
Answer:
a
Step-by-step explanation:
i am smart
Answer:
B
To change a fraction into a percent you need to turn it into a decimal so you can then move the decimal place 2 times to the right. It looks something like this:
1/2 ------> 0.5 -----------> 50%
To change a percent into a decimal move the decimal place twice to the left. Like so:
85.5% ------> 0.855

evaluate (distributive property)
9*6= ? sixes + 4 sixes
=30 + ?
=???
Answer:
Step-by-step explanation:
If A, B and C are integers, according to distributive property;
A(B+C) = AB+AB
A is distributed over B and C
Given
9×6 = 5 sixes +4 sixes
5 sixes = 5(6) =30
4 sixes = 4(6) =24
9×6 = 5(6)+4(6)
9×6 = 30+24
9×6 = 54
Hence ? =5,?? =24 ??? = 54

Terry earns a base salary of $2100 per month. Once he reaches $40000 in total sales, he earns an additional 5% commission (salary) on the amount of sales over $40000. Let s be the amount of his total sales for the month and M(s) be the amount of his salary for the month. (For instance, if he had sales of $42000 for the month, he would earn a salary of $2100 and 5% of $2000, since $42000 is $2000 more than $40000.)
Answer:
$4200Step-by-step explanation:
Step one:
given data
we are told that Terry's base salary is $2100 per month.
in addition 5% on sales greater than $40000.
let the monthly salary be M(s)
and let "s" be the amount of sales made
his monthly commission =0.05s
Step two:
The expression for his monthly earning is given as
M(s)=0.05s+2100 where s>40000
hence for a month when s=42000
M(s)=0.05(42000)+2100
M(s)=2100+2100
M(s)=4200
Therefore for an instance when s=42000 his earnings for the month will be $4200
determine the intersepts of the lines
Answer:
Y-intercept is (0, 100) and the X-intercept is (-250, 0)
Step-by-step explanation:
For the y-intercept the line from the origin does not move left or right and stays at 0 but it goes up by 100.
For the x-intercept the line does not go up and down but it goes to the left -250.

John puts $1,500 in a savings account that earns 7% simple interest annually. Find the new
balance in his savings account after three years if John does not deposit or withdraw any
money.
Answer:
$1,815
Step-by-step explanation:
Use the simple interest formula, I = prt
Plug in the values we know:
I = prt
I = (1,500)(0.07)(3)
I = 315
Add this to the original amount:
1500 + 315
= 1,815
So, John will have $1,815 in his account after 3 years.

It is known that the variance of a population equals 1,936. A random sample of 121 has been taken from the population. There is a .95 probability that the sample mean will provide a margin of error of a. 7.84 b. 31.36 c. 344.96 d. 1,936
Answer:
It is known that the variance of a popualtion equals 1,936.
Step-by-step explanation:
That should be correct!!!
There is a 0.95 probability that the sample mean will provide a margin of error of 7.84.
What is mean by Probability?The term probability refers to the likelihood of an event occurring.
Given that;
The variance of a population = 1,936
And, A random sample of 121 has been taken from the population.
Now,
Since, Standard deviation = √ Variance
= √1,936
= 44
Hence, The standard error = 44 / √121
= 44 /11
= 4
We know that;
The critical z factor for a confident interval of 0.95 = ± 1.96
Thus, The sample mean will provide a margin of error = 4 × 1.96
= 7.84
