Answer:
83/100
Step-by-step explanation:
step 1- Address input parameters & values.
Input parameters & values: The decimal number = 0.83
step 2- Write it as a fraction
0.83/1
step 3- Multiply 100 to both numerator & denominator
(0.83 x 100)/(1 x 100) = 83/100
It can be written as 83% = 83/100 or 83/100
step 4- To simplify 83/100 to its lowest terms, find LCM (Least Common Multiple) for 83 & 100.
1 is the LCM for 83 & 100
step 5- As LCM is 1, the fraction can't be factorized further
83/100 is a simplest fraction for the decimal point number 0.83

Answer:
It is 83/100.
Step-by-step explanation:
1. Notice the decimal numbers. They end in the hundredths place.
2. After acknowledging this you know by this that it will be the decimal over 100, like ??/100.
3. Since the decimal is 0.83, we know that it will be 83 over 100. Solved for 83/100.

scores? Explain.
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h
of homework?
(c) What does the number 40 in Part (b) mean in the context of the situation?
Answers
B) y =8x+40 = y=8(3)+40 = 24+40 = 64
C) 40 would be the test score if no time was spent doing homework
Answer:
We have been given the scatter plot:
(a)We can clearly see from the plot that there is direct proportion between the number of hours of homework and test scores.
Direct proportion means if hours of homework increases then test score increases and vice-versa.
(b) we have been given a function y=8x +40
We need to predict for 3 hours of homework put x=3 in above function as x represents hours of homework we get:
y=8(3)+40
y=24+40
y=64
Hence test score will be 64 for 3 hour of homework.
(c) 40 means the test score when there is x=0 means 0 hours o homework.

We know that scarves cost $5 each, and purses that cost $12 each. We also know that the cost of Rebecca's entire purchase is 39 dollars.
So,
5n + 2p = $39
However, we were also given that Rebecca buys a total of 2 purses, so we can plug that into the equation.
5n + 2(12) = 39
When simplified, we get:
5n +24 = 39
To simplify even further, we must subtract 24 from both sides of the equation.
5n = 15
Finally, we must divide both sides by the coefficient of the variable, or 5.
n = 3
Therefore, Rebecca buys 3 scarves.
However, this problem didn't ask you to solve the equation, therefore the correct answer in this situation is probably one of the ones we started out with, either
5n + 2(12) = 39
or
5n +24 = 39
