Do you want to know how to write the decimal number 5.4 as a fraction?
Here we will show you step-by-step how to convert 5.4 so you can write it as a fraction.
You can take any number, such as 5.4, and write a 1 as the denominator to make it a fraction and keep the same value, like this:
5.4 / 1
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 5.4, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 10 to get the following fraction:
54 / 10
Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.
The GCD of 54 and 10 is 2. When we divide the numerator and denominator by 2, we get the following:
27 / 5
Therefore, 5.4 as a fraction is as follows:
27 / 5

Kelly is recording the temperature of a cooling chemical. Using the table, determine the initial
temperature of the chemical when she poured into the beaker.
Answer:
Initial temperature of the chemical = 97°
Step-by-step explanation:
Time Temperature Difference
4 89.5 -
10 78.25 78.25 - 89.5 = -11.25
16 67.00 67 - 78.25 = -11.25
There is a common difference of -11.25 in each successive term.
Therefore, cooling of a chemical represents a linear function.
Let the function representing temperature is,
f(t) = at + b
Where 'a' = rate of change in temperature
b = initial temperature
t = time
Now 'a' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{78.25-89.5}{10-4}[/tex]
a = -1.875
f(t) = -1.875t + b
For t = 4 and f(t) = 89.50,
89.50 = -1.875(4) + b
b = 97
Therefore, function representing the cooling of chemical is,
f(t) = -1.875t + 97
And the initial temperature of the chemical was 97° when it was poured into the beaker.
What is the value for x? 8x-13 and 5x+14
Answer:
9
Step-by-step explanation:
8x-13=5x+14
you subtract 5x from both sides and get
3x-13=14
then add 13 to both sides and get
3x=27
then divide 3 from both sides
3/3=x
27/3=9
x=9
Answer:
x = 9
Step-by-step explanation:
8x - 13 = 5x + 14 Subtract 5x from both sides of the equation 3x - 13 = 14 Add 13 to both sides of the equation 3x = 27 Divide by 3 for both sides of hte eqation x = 9

5y +3> -7y + 13
Answer: Y>5/6
Step-by-step explanation: I had this on khan Academy and got this right
The solution to the inequality 5y + 3 > -7y + 13 is y > 5/6.
What is the solution to the inequality?Given the inequality in the question:
5y + 3 > -7y + 13
To solve the inequality 5y + 3 > -7y + 13, combine like terms on both sides and isolate the variable term:
5y + 3 > -7y + 13
Add 7y to both sides of the inequality:
5y + 7y + 3 > -7y + 7y + 13
5y + 7y + 3 > 13
12y + 3 > 13
Next, subtract 3 from both sides of the inequality:
12y + 3 - 3 > 13 - 3
12y > 10
Isolate variable y by dividing both sides by 12:
y > 10/12
Simplifying, we get:
y > 5/6
Therefore, the solution is y > 5/6.

In a class of 40 students, 19 play tennis, 20 play netball and 8 play both of these sports. A student is randomly chosen from the class. Determine the probability that the student plays tennis.
Answer:
19/40 OR 0.475 OR 47.5%
Step-by-step explanation:
The probability of an event is calculated by dividing the total number of 'favorable outcomes' by the number of total outcomes. Here, the number of 'favorable outcomes' is the number of students who play tennis, so 19. The total number of outcomes is 40 as there are 40 students. Therefore the probability a student plays tennis is 19/40, or 0.475 or 47.5%.

Select all the situations that can be represented by 1/2⋅5. * 1 point Diego lives 5 miles from school, and Elena lives 1/2 as far away as Diego. How many miles does Elena live from school? Jada has 5 bottles that each contain 1/2 liter of water. How many liters of water is that in total? Noah has 5 meters of rope. How many pieces of rope of length 1/2 meter can he cut from it? Lin's goal is to run 5 miles. She ran 1/2 mile. What fraction of her goal is that?
Answer:
Elena lives 2.5 miles away from school.The total liters of water is 2.5 litersHe can cut 10 pieces of rope of length 1/2 meterThe fraction of her goal she ran is 1/10Step-by-step explanation:
From the question,
Diego lives 5 miles from school, and Elena lives 1/2 as far away as DiegoTherefore, Elena lives 1/2 of 5 miles away from school.
1/2 of 5 miles = 2.5 miles
Hence, Elena lives 2.5 miles away from school.
Jada has 5 bottles that each contain 1/2 liter of water.Since each bottle contain 1/2 liter of water, then
The total liters of water is (1/2 × 5) liters
1/2 × 5 = 2.5 liters
Hence, the total liters of water is 2.5 liters
Noah has 5 meters of ropeTo determine how many pieces of rope of length 1/2 meter he can cut,
Number of pieces of rope of length 1/2 meter that can be cut is 5 meter ÷ 1/2 meter
5 meter ÷ 1/2 meter = 10
Hence, he can cut 10 pieces of rope of length 1/2 meter.
Lin's goal is to run 5 miles. She ran 1/2 mile.To determine what fraction of her goal that is,
First, she ran 1/2 mile out of 5 miles.
The fraction of her goal she ran is 1/2 mile ÷ 5 miles
1/2 mile ÷ 5 miles = 1/10
Hence, the fraction of her goal she ran is 1/10.

A particular rocket taking off from earths surface uses fuel at a constant rate of 12.5 gallons per minute. The rocket initially contains 225 gallons of fuel
Answer:
Y=12.5x+225
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
A particular rocket taking off from the earth surface uses fuel at a constant rate of 12.5 gallons per minute the rocket initially contains 225 gallons of fuel determine a linear model and Y equals X plus B form for the amount of fuel Y as a function of the number of minutes x at the rocket has burned
We were told to determine a linear model, where Y equals X plus B form for the amount of fuel Y as a function of the number of minutes x at the rocket has burned.
If we interpret this we have, Y=X+B , this equation can be compared to the standard equation of slope intercept of
Y= mx+b
Where the m is the slope, and b is the initial value at "y" intercept.
From the question, we were told that Y denotes a function of the number of minutes x at the rocket has burned
The given slope from the question, which is the rate= 12.5 gallons per minute
The given initial value =225 gallons of fuel which the value of "b"
If we substitute into the equation of the slope, we have;Y=12.5x+225 which is the required linear model .
