Answer:
D.75 is the answer
Step-by-step explanation:
We already have our first value 15 and the second value 20. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 115 = 20% × Y
STEP 215 =
20
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
STEP 3Y = 15 ×
100
20
STEP 4Y = 15 × 100 ÷ 20
STEP 5Y = 75
Finally, we have found the value of Y which is 75 and that is our answer.
You can easily calculate 15 is 20 percent of what number by using any regular calculator, simply enter 15 × 100 ÷ 20 and you will get your answer which is 75
Answer:
75
Step-by-step explanation:
15 is 20% of What Number?
15 is 20% of What Number? - 15 is 20% of 75. 100% of 75 is 75, therefore 20 percent of 75 equals 15. To learn how to solve 15 is 20 percent of what number, see the step by step instructions below.
15 is 20 Percent of What Number?
75
Formula = Number x 100
Percent = 15 x 100
20 = 75
Following shows the steps on how to derive this formula and find out 20% of what number is 15.
Step 1: If 20% of a number is 15, then what is 100% of that number? Setup the equation.
15
20% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
20Y = 15 x 100
20Y = 1500
Y = 1500
100 = 75
match these equations balncing steps with the discription of what was done in each step

Step-by-step explanation:
12x - 6 = 10
divide both sides by 2
6x - 3 = 5
add 3 to both sides
6x = 8
multiply both sides by 1/6
x = 4/3

Which of the following proportions could be used to convert 6 days to hours?
Answer:
[C] [tex]\frac{6\;days}{x\;Hours}=\frac{1\;day}{24\;Hours}[/tex]
Step-by-step explanation:
Since, we know that
1 Day = 24 Hours
6 Days = x Hours
Cross Multiply:
6 x 24 = 144
1x = 144
x = 144
144 = 144
Hence, the best answer is [C] [tex]\frac{6\;days}{x\;Hours}=\frac{1\;day}{24\;Hours}[/tex]
~lenvy~
The following proportions could be used to convert 6 days to hours as 1 day : 24 hours :: 6 days : x hours.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
There is a way to convert 6 days to hours, to use the proportion:
⇒ 1 day : 24 hours :: 6 days : x hours
This proportion shows the relationship between days and hours, and can be used to convert from one unit to the other. To solve for x, we can cross-multiply and divide:
x = 6 days × 24 hours / 1 day = 144 hours
So, 6 days is equivalent to 144 hours.
Hence, the correct answer would be an option (C).

What is the value of x?
Answer:
x = 10
Step-by-step explanation:
the two angles shown are supplementary, they add up to 180 degrees
so we can write this equation to solve for 'x':
100 + 9x - 10 = 180
90 + 9x = 180
9x = 90
x = 10
Answer:
[tex]\tt x=10^o[/tex]
Step-by-step explanation:
The given angles are supplementary angles, meaning they add up to 180°.
[tex]\tt 100+ 9x - 10 = 180^o[/tex]
[tex]\tt 90 + 9x = 180^o[/tex]
[tex]\tt 90+9x-90=180-90\:\: (Subtract)[/tex]

let's write 2*2*2*2*2*2*2*2*2 in exponential form.
Notice 2 has been multiplied times itself 9 times.
Basic exponential notation:-
[tex]\sf{2*2=2^2}[/tex]
[tex]\sf{2*2*2=2^3}[/tex]
[tex]\sf{2*2*2*2=2^4}[/tex]
You should notice a pattern.
This is the pattern:-
The number of times 2 has been multiplied times itself is the exponent.
In this case, we multiplied 2 times itself 9 times.
Hence, the answer is

Robert had some friends at his house after school. His mom cut up 2 pies for them to eat. If she cut each pie into fourths, how many pieces will there be? Choose the model that represents the answer.
1/4
8/8
2/8
4/4
NO LINKS!!!!!)
Answer:
8/8
Step-by-step explanation:
There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).
Basically, multiply how many fourths (four per pie) by how many pies there are.
4 x 2 = 8
There are 8 pieces.

Answer:
a. the relationships between the area of walls left to paint and the time they have been working
b. Company 1
c. Company 2
d. Company 1 = 147 hours, company 2 = 162 hours
Step-by-step explanation:
a. The linear functions model the relationships between the area of walls left to paint and the time they have been working.
b. Company 1 is painting faster because the first line has a slope of -1000/7 while the second line has a slope of -100/9, which means Company 1 is painting 100 ft^2 every 7 hours while Company 2 is painting 100 ft^2 every 9 hours. Therefore Company 1 is going faster.
c. Company 2 had less area to paint when they began because at the 0 hour mark, company 1 had 2100 ft^2 to paint and company 2 had 1800 ft^2 to paint.
d. Company 1 will take 21*7=147 hours to finish. Company 2 will take 18*9=162 hours to finish.

Please help I have a meeting with my teacher and one of the study guide questions is "how can we interpret fractions" please help i'm giving 40 points and ill also give brainliest if you could just explain what it means
Answer:
Fractions have different applications in the real word. We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie. They can also be interpreted as decimals and percentages.
Step-by-step explanation:
Hope this helps!
All the correct methods to interpret fractions is,
Fractions as parts of wholes or parts of sets;
Fractions as the result of dividing two numbers;
Fractions as the ratio of two quantities;
Fractions as operators; and fractions as measures.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;

distance/time225/375 miles/hr======================
1 hours → 75 miles
? hours → (1125/75)
15 hoursIt takes her 15 hours to drive 1125 miles.
Answer:
15 hours
Step-by-step explanation:
Finding how much distance in 1 hour
⇒ Ceci = 225 miles = 3 hours
⇒ 225 miles = 3 hours
⇒ 225/3 miles = 3/3 hours
⇒ (25 x 9)/3 miles = 1 hour
⇒ (25 x 3) miles = 1 hour
⇒ 75 miles = 1 hour
Finding how much hours in 1125 miles
⇒ 75 miles = 1 hour
⇒ 75x miles = 1125 miles = x hours
⇒ 75x/75 = 1125/75
⇒ x = 15
⇒ 75(15) miles = 1125 miles = (15) hours
⇒ 1125 miles = (15) hours
