You are on an academic committee tasked to evaluate state employment math test questions. The following question has come to the attention of the committee:
"Each of the four digits 3, 4, 5, and 8 is placed in one of the boxes to form a fraction. The numerator and the denominator are two-digit whole numbers. What is the smallest value of all the common fractions that can be formed? Express your answer as a reduced fraction."
There are 4 boxes arranged in a square with 2 boxes side-by-side directly on top of the other 2 boxes. There is a horizontal line representing a fraction bar separating the top 2 boxes from the bottom 2 boxes.
Some committee members contend this is not a valid question.
Solve the problem. (If there is no solution, enter NO SOLUTION.)
Explain the solution to prove (or disprove) the question's validity.
The question is valid because to make the fraction as small as possible, you make the numerator as small as possible and make the denominator as large as possible.The question is valid because to make the fraction as small as possible, you make the numerator as large as possible and make the denominator as small as possible. The question is valid because to make the fraction as small as possible, you make both the numerator and the denominator as small as possible.The question is valid because to make the fraction as small as possible, you make both the numerator and the denominator as large as possible.The question is not valid because there is no solution.
Answer:
no solution that's my answer
The valid solution to the problem is: The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.
Let's solve the problem step by step to determine the smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8. We'll express the answer as a reduced fraction.
We have 4 boxes arranged in a square as described:
A B
C D
The fraction can be represented as AB/CD.
To make the fraction as small as possible, we need to arrange the digits in a specific way. We want to minimize the numerator (AB) and maximize the denominator (CD).
For the numerator (AB), we want the smallest two-digit number. The smallest two-digit number that can be formed using the digits 3, 4, 5, and 8 is 34.
For the denominator (CD), we want the largest two-digit number. The largest two-digit number that can be formed using the digits 3, 4, 5, and 8 is 85.
Therefore, the smallest fraction that can be formed is 34/85.
To ensure that this fraction cannot be further reduced, we need to check if 34 and 85 share any common factors greater than 1. If they do not share any common factors other than 1, then the fraction is in its reduced form.
Checking for common factors:
Factors of 34: 1, 2, 17, 34
Factors of 85: 1, 5, 17, 85
The only common factor is 1, which means the fraction 34/85 is already in its reduced form.
Thus, the valid solution to the problem is:
The smallest value of all the common fractions that can be formed using the digits 3, 4, 5, and 8 is 34/85.

Rounding in the calculation of monthly interest rates is discouraged. Such rounding can lead to answers different from those presented here. For long-term loans, the differences may be pronounced.
Several years ago Bill got a home mortgage of $116,000 with a term of 30 years at an APR of 9%. Use the Monthly Payments for Long-Term Loans Rule of Thumb to estimate his monthly payment.
$
Compare this estimate with what the monthly payment formula gives. (Round your answer to the nearest integer.)
The actual monthly payment is about $
greater than the estimated payment.
Bill's projected monthly payment under the Monthly Payments for Long-Term Loans using the Rule of Thumb is $870.00.
Bill's exact monthly payment using the Monthly Payments calculation is $933.36.
The real monthly payment is approximately $63.36 more than the predicted cost.
Simple procedures may be used to calculate the Monthly Payments for Long-Term Loans Rule of Thumb.
To begin, divide the annual percentage rate (APR) by 12 to obtain the monthly percentage rate (MPR).
Second, calculate the MPR on the principal amount. The product is the estimated monthly payment, which is similar to the real monthly payment and was computed using a financial calculator below.
Estimated Monthly Payment:
Home Mortgage = $116,000
Term of loan = 30 years
APR = 9%
Monthly interest rate = 0.0075 (0.09/12)
Estimated monthly payment based on the Monthly Payments for Long-Term Loans Rule of Thumb
($116,000 x 0.0075) = $870
Actual Monthly Payment Formula:
N (# of periods) = 360 months (30 x 12)
I/Y (Interest per year) = 9%
PV (Present Value) = $116,000
FV (Future Value) = $0
The outcome is given as:
PMT = $-933.36
Sum of all periodic payments = $-336,010.40
Total Interest = $220,010.40
Actual monthly payment = $933.36
Estimated monthly payment 870.00

Given A and B are vertical angles with m /A = 20x + 10 and m/B = 30x - 10.
What is x?
Answer:
to solve for x, you gotta make the two equations equal to each other then you can move the numbers to get the value of x
20x+10=30x-10
20x-30x=-10-10
-10x=-20
x=2
Answer:
x=2
Step-by-step explanation:
if m/A and m/B are equal, to find x, your equation would be 20x+10=30x-10. doing two step equations, you would substract 20x from both sides, making your equation look like 10=10x-10. then you would add 10 from both sides making your equation 20=10x. then you would divide 10x from both sides making x=2.

The approximate average mouse heart beats = 1.008[tex]\times10^6[/tex] times per day.
We have to find the how many beats more does the mouse heart beats in a day.
Since we have to find the more heart beat of mouse comparing to the human heartbeats. So we subtract their heart beat.
The human heartbeats have [tex]10^5[/tex] while mouse heartbeats have [tex]10^6[/tex]. So we first equal the power of 10. After equal the power we can easily find the value of the more heart beat of mouse.
We can write,

Now,
The more heartbeats of mouse = average mouse heart beats − average human heart beats.
The more heartbeats of mouse [tex]= 1.008\times10^6-0.1037\times10^6[/tex]
The more heartbeats of mouse [tex]=(1.008-0.1037)\times10^{6}[/tex]

the length of a rectangle is four times it's width. if the perimeter is at most 106 centimeters, what is the greatest possible value for the width?
Lenght of a rectangle: L
Widht of the rectangle: W
Perimeter of the rectangle: P
length of a rectangle is four times it's width: L = 4W
Perimeter is at most 106: P <= 106
Perimeter is 2L + 2W: P = 2L + 2W
P <= 106
if we use the value of P = 2L + 2W, we can write:
2L + 2W <= 106
Since L = 4W, then we can write this equation:
2L + 2W <= 106
2(4W) + 2W <= 106
8W + 2W <= 106
10W <= 106
W <= 106/10 = 10.6
W <= 10.6
Therefore, the greatest possible value for the width is 10.6
