Answer:
450
Step-by-step explanation:
Formula = Number x 100
Percent = 81 x 100
18 = 450
Following shows the steps on how to derive this formula
Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.
81
18% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
18Y = 81 x 100
18Y = 8100
Y = 8100
100 = 450
Answer:
450
Step-by-step explanation:
18% of 450 is 81. 100% of 450 is 450, therefore 18 percent of 450 equals 81. To learn how to solve 81 is 18 percent of what Number, see the step by step instructions below.

Answer: i will give you the first couple answers and how i got it you do the rest yourself. You need to combine like terms so add or subtract only the same numbers with the same sign. if the sign has no number imagine an invisible 1 before it. so for example the first one would be (4A) all i did was add the A together to get that i will also give you the last answer for another example. the problem is 20-9z+4y+7-x. all you gotta do is add 7 to the 20 add -9+-x and leave the 4y alone since there is no other y the answer would be 27-10z+4y+

What is the value of 9(4x - 4), when x=5?
Do all multiplication first, then solve the problem from left to right.
ILL GIVE BRAINLIET
I believe by asking you to do all multiplication first they are asking you to demonstrate the distributive property, this means we can distribute the 9 through the parenthesis by multiplying it by each part inside the parenthesis, this gives us:
36x - 36
now we can substitute 5 in for x to get:
36(5) -36

well without rounding anything, I got 511.9999999992 people
Step-by-step explanation:
so the ratio I used was 36 people for every 225 people( 225 because in total he asked 225 people) then I divided 3,200 into 225 to see how many times It would fit, the answer was 14.2222222222 then I multiplied that by 36 and my answer was 511.9999999992 people. I hope this helps, I tried to be as accurate as possible.

Answer:
b = 17.55
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + b^2 = 18^2
16 + b^2 = 324
-16 -16
b^2 = 308
square root them
b = 17.55
let me know if it is correct!
Step-by-step explanation:
4^2 + h^2 = 18^2
16 +h^2 = 324
h^2 = 308
h = √308
h = 17.5499 ft

The lines 2x - y = 8 and 4x - 2y = 16 intersect at _______.
The solution is Option C.
The system of equations are same and they have infinite number of points
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first equation be P
2x - y = 8 be equation (1)
Let the second equation be Q
4x - 2y = 16 be equation (2)
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ ) = 2
Substituting the values in the equation , we get
Divide equation (2) by 2 , we get
2x - y = 8 be equation (1)
Therefore , the value of equation (1) = equation (2)
Hence , there are infinite number of solutions to the equations

[A] is making 25 sundaes with mint, chocolate, and vanilla ice cream.
3/5 of the sundaes are mint ice cream and 1/2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?
Answer:
5 sundaes
Step-by-step explanation:
find the GCF: 5
so 3x5 would be 15
15 mint.
25-15=10
10/2=5

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
It is given that, there is [tex]$25$[/tex] sundaes with mint, chocolate and vanilla flavor ice cream out of these [tex]$\frac{3}{5}$[/tex] of the sundaes are mint flavor and [tex]$\frac{1}{2}$[/tex] are chocolate flavor.
We have to find the number for sundaes will be vanilla flavor ice-cream.
So,
We have to multiply [tex]$3$[/tex] by [tex]$5$[/tex] and solve it.
So,
[tex]$3\times 5=15$[/tex]
There are [tex]$15$[/tex] mints flavor.
Now,
Divide total number of sundaes with all flavor ice-cream by calculate value for mint.
We get,
[tex]$25-15=10$[/tex]
Multiply the above calculate value by no. of remaining sundaes for chocolate ice-cream.
So,
[tex]$10\times \frac{1}{2}=5$[/tex]
Hence, there are [tex]$5$[/tex] sundaes will be vanilla flavor ice-cream.

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?
Answer:
[tex]60[/tex] times
Step-by-step explanation:
There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!
