Mackenzie needed to get her computer fixed. She took it to the repair store. The
technician at the store worked on the computer for 2.75 hours and charged her $181
for parts. The total was $249.75. Write and solve an equation which can be used to
determine 2, the cost of the labor per hour.
The cost of the lab per hour is $25.
How to determine the cost of the labor per hour?
Here we know that they charged a total of $249.75, and the cost in parts was $181, then the cost in labor is:
$249.75 - $181 = $68.75
And we know that they worked for 2.75 hours, the cost per hour is given by the quotient between the cost in labor and the number of hours, then we can get:
$68.75/2.75 = $25
So we can see that the cost of the lab per hour is $25.

The difference between 9493 take away 2324
Difference in math is the result of one of the important mathematical operations, which is obtained by subtracting two numbers. It tells us by how much a number differs from the other. The aim of finding the difference in math is to tell how many numbers lie between the two given numbers.
Set difference is a generalization of the idea of the complement of a set and as such is sometimes called the relative complement of T with respect to S. The symmetric difference between two sets S and T is the union of S – T and T – S.
Based on the conditions, formulate :
Let us assume,
The difference between value = x
We can write,
x = 9493 - 2324
Calculate the sum or difference,
x = 7169.
Therefore,
The difference between 9493 take away 2324 is equal to = 7169.

Answer:
4 7/15
Step-by-step explanation:
To subtract two fractions we need to have them have the same division by, which means the lower part of the fraction needs to be the same. To do that we would need to find a common denominator between 3 and 5, a number that can be both divided by 3 and 5. To figure common denominator for 5 and other nimbery just multiply the other number by 5: 3*5=15. so now we need to multiply both fractions by a number to get lower part to 15, so 4*3/5*3=12/15 and 1*5/3*5=5/15. Now we have 6 12/15 - 2 5/15 = 4 7/15.

as 9 hundreds is 9 thousands
Answer:
10 as 9 hundreds is 9 thousand.
Step-by-step explanation:
The digit is 9 thousand which can be written as 9,000
It can also be written as,
9,000 = 9 x 1000
or ,9,000 = 9 x 10 x 100
So, to require 9 hundreds multiply 9 by 100 in the expression above
9,000 = 10 x 900
And so Ten as 9 hundreds are 9 thousand.

Calculate the interest which Tito has to pay on loan ?
Determine the total amount to be paid back
Determine the monthly repayment amount
If Tito took a loan of $10000 from a bank to be repaid within 4 years, at 12% Simple interest per annum, then, he will have to pay overall $4800 as interest to the bank over 4 years and a total payment of $14800 at the end of the 4th year to repay and close off the loan.
As per the question statement, a bank charges 12% Simple interest per annum on cash loans to its clients and Tito took a loan of $10000 from the same bank to be repaid within 4 years.
We are required to calculate the overall interest Tito has to pay to bank if he repays and closes the loan at the end of 4th year, and also to calculate the total payment required to repay and close off the loan at the end of the 4th year.
To solve this question, we need to know the formula to calculate the interest amount in case of simple interest which goes as
Interest (I) [tex]=(\frac{P*R*T}{100} )[/tex]
where, "P" = Principle amount of Loan,
"R" = Rate of simple interest charged on the principle per annum, and
"T" = Time period within which, the loan is to be repaid.
Here, (P = 10000), (R = 12%) and (T = 4). Then, the overall interest Tito will have to pay at the end of 4th year = [tex](\frac{10000*12*4}{100}) = (100*12*4)=(48*100)=4800[/tex]
And total amount to be paid to repay and close of the loan at the end of 4th year will be = $[4800 + 10000] = $14800.

Suppose that 27 slips of paper numbered 1 to 27, inclusive, are put into a hat. Then one is drawn out at random. Find the probability of getting slip 12 and even numbers and prime numbers
The probability of getting-
slip 12 = 1/27even numbers = 13/27, andprime numbers = 1/3.What is meant by probability?Probability is the measure of how likely an event is to occur. Many events are impossible to predict to absolute certainty. We can only predict the possibility of an event occurring, i.e. how likely it is to occur, using it.
The formula for probability is;
Probability(event) = favourable outcome/ total outcome
Now, as per the given question;
There are 27 papers put in a hat numbering from 1 to 27.
The sample space will be;
s = {1,,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27}
The total outcome is 27.
The total number of 12 digit in the sample space is 1.
Thus, the probability for getting slip 12 is;
Probability(slip 12) = 1/27
The sample space for even number are;
s = {2,4,6,8,10,12,14,16,18,20,22,24,26}
Now, there are total number of even digits in the sample space is 13.
Thus, the probability for getting even number is;
Probability(even) = 13/27.
The sample space for prime number are;
s = {2,3,5,7,11,13,17,19,23}
Noe, the total number of prime digits in the sample space is 9.
Thus, the probability for getting prime number is;
Probability(prime) = 9/27 = 1/3
Therefore, the probability for getting the prime number is 1/3.
