How do I find the percent of a number?
Answers
Answer:
[tex]\frac{x}{100} =[/tex] the value you are solving for over total value.
Step-by-step explanation:
The way I learned it was like this:
Let's say you're trying to find the percent of red marbles there are in a pile. You have 24 red marbles and there are 48 in all. Set it up like so:
[tex]\frac{x}{100} =\frac{24}{48}[/tex]
x is over 100 because all percents are out of 100, and 24 is over 48 because that's the value you are trying to solve the percent for. Then cross-multiply.
[tex]\frac{x}{100} =\frac{24}{48}\\48(x)=24(100)\\48x=2400[/tex]
Then divide.
[tex]48x[/tex] ÷[tex]48x=2400[/tex] ÷ [tex]48[/tex]
[tex]x=50[/tex]
So the percentage is fifty.

Answer:
300 ft³
Step-by-step explanation:
The easiest thing to do is to separate it into 3 cuboids. Then work out the volumes of each cuboid and add them together.
Volume of a cuboid = width x height x depth
The left cuboid has a width of 12 - 5 - 4 = 3 ft
From inspection, it has a height of 4 ft and a depth of 5ft.
So the volume of this is 3 x 4 x 5 = 60 ft³
The middle cuboid has a height of 6 + 2 = 8 ft
From inspection, it has a width of 5ft and a depth of 5ft
So the volume of this is 8 x 5 x 5 = 200 ft³
Finally, the right cuboid has a width of 4ft, a height of 2 ft and a depth of 5ft. So the volume is 4 x 2 x 5 = 40 ft³
Therefore, the total volume = 60 + 200 + 40 = 300 ft³

9√2
Step-by-step explanation:
a^2+b^2=c^2
a^2+b^2=18^2
a^2+b^2=324
324 ÷ 2 = 162
162 + 162 = 324 (on a 45 45 90 right triangle)
81 and 2 are factors of 162
square root of 162
√162 = √81 * 2 = 9√2

Answer:
y= -2, x= -3
Step-by-step explanation:
Firstly, substitute the x and y values:
-x + 5(0)= -7
x+ 0 = -5
second thing to check: DSA - different signs addition (positive x and -x)
-x+5y=-7 take away x+y=-5
6y= -12
y= -2
To find x: -x + 5(-2)= -7
-x= -7 + 10
x= -3

Explanation:
Sounds like my problem in math class, I always do mental math, and the teacher always asks me to show my work.
So anyway, 7/10 with work being shown would be… uh complicate the math.
Set it up as long division.
So 7/10 (I hope you know how to set up long division, because I can’t type it.)
And just solve it with that. It’s not going to be different, but it will have the appearance that you used an on paper equation to solve it.
Hope this helps!

During an experiment, the temperature of a mixture changes from 12 1/4°F to 15 3/5°F. What is the percent of increase in the temperature of the mixture?
Answers
The percentage increase is 21.4% increase
Given Data
Initial temperature = 12 1/4°F = 49/4 = 12.25°F
Final Temperature = 15 3/5°F = 78/5 = 15.6°F
We know that the expression for percentage increase is given as
Percent Increase = Increase/Final *100
Percent Increase = 15.6-12.25/15.6 *100
Percent Increase = 3.35/15.6 *100
Percent Increase = 0.214 *100
Percent Increase = 21.4%
Hence there is a 21.4% increase

What are the benefits of creating and using functions in your code?.
Answers
A few of the advantages include the following:
The function can be called from anywhere in the code and made to perform exactly what it was written for the first time if it is called from a different line of code.
2. Writing functions reduces redundancy by allowing for fewer lines of code to be written in total. It eliminates the need to rewrite numerous lines of code over and over again. After the initial line of code has been set, we can call the method from another location.
3. It increases the efficiency of coding.
4. It makes it easier for others to comprehend the fundamentals involved in a coding structure, which is an advantage.

Approximately how many square inches of fabric were used to make the triangular flag? 15 square inches 76 square inches 186 square inches 215 square inches.
Answers
The area used to make the triangular flag is 15 square inches.
Given
Two of the sides are 8 in.
Lila made a triangular flag to cheer on her favorite sports team.
The perimeter of the flag is 20 inches.
What is Heron’s formula?Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.
Then,
The value of S is;
[tex]\rm S = \dfrac{20}{2}\\\\S =10[/tex]
Therefore,
The area used to make the triangular flag is;
[tex]\rm Area = \sqrt{s(s-a)(s-b)(s-c)} \\\\A rea= \sqrt { (10)(10-8)(10-8)(10-4) }\\\\Area = \sqrt{10 \times 2 \times 2\times 6}\\\\Area = \sqrt{240}\\\\Area = 15.49[/tex]
Hence, the area used to make the triangular flag is 15 square inches.
