Answer:
0.6796875
Step-by-step explanation:
1. We assume, that the number 9.375 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 9.375 is 100%, so we can write it down as 9.375=100%.
4. We know, that x is 7.25% of the output value, so we can write it down as x=7.25%.
5. Now we have two simple equations:
1) 9.375=100%
2) x=7.25%
where the sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
9.375/x=100%/7.25%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 7.25% of 9.375
9.375/x=100/7.25
(9.375/x)*x=(100/7.25)*x - we multiply both sides of the equation by x
9.375=13.793103448276*x - we divide both sides of the equation by (13.793103448276) to get x
9.375/13.793103448276=x
0.6796875=x
x=0.6796875
now we have:
7.25% of 9.375=0.6796875
The percentage of the mile 7.25% of 9.375 =0.6796875.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have to find percentage of the mile times range from 7.25 to 9.375.
let 9.375 represents 100% and x represents 7.25%.
Then, using proportion we can write
9.375/x=100%/7.25%
9.375/x=100/7.25
9.375 (7.25)= 100x
100x = 67.96875
x= 0.6796875
Thus, 7.25% of 9.375 =0.6796875

Solving the Question
We're given:
There were 478 people in total.$1.75 per child$2.25 per adultTotal revenue of $975We must find the number of children and adults who swam.Set variables:Let a represent the number of children who swam.
Let b represent the number of adults who swam.
Create equationsBecause we've set two variables, we need two equations to be able to find the answers.
One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.
Number of people:
[tex]a+b=478[/tex]
The number of children + the number of adults = 478 in totalPrice:
[tex]1.75a+2.25b=975[/tex]
$1.75 per child + $2.25 per child = $975 in totalSolve equations[tex]a+b=478[/tex][tex]1.75a+2.25b=975[/tex]We can solve this question using substitution, where we plug one equation into the other.
Isolate a in the first equation:
[tex]a+b=478\\a=478-b[/tex]
Plug the first equation into the second equation by replacing a:
[tex]1.75a+2.25b=975\\1.75(478-b)+2.25b=975[/tex]
Solve for b:
[tex]1.75(478-b)+2.25b=975[/tex]
⇒ Open up the parentheses:
[tex]836.5-1.75b+2.25b=975\\836.5-0.5b=975[/tex]
⇒ Subtract 836.5 from both sides to isolate b:
[tex]-0.5b=138.5[/tex]
⇒ Divide both sides by -0.5:
[tex]b=277[/tex]
Therefore, there were 277 adults in total.Solve for a:
[tex]a+b=478[/tex]
⇒ Replace b with 277:
[tex]a+277=478\\a=201[/tex]
Therefore, there were 201 children in total.Answer
There were 201 children and 277 children at the pool that day.

supplementary angles are when two angles sum up to 180 degrees.
∠x and ∠y are supplementary angles
===============
∠x + ∠y = 180°∠x + 116° = 180°∠x = 180° - 116°∠x = 64°Answer:
64°
Step-by-step explanation:
Supplementary angles are two angles that add up to 180°.
∠x + ∠y = 180° <== substitute 116° for ∠y
∠x + 116° = 180° <== subtract 116 from both sides
- 116 - 116
∠x = 64° <== measure of ∠x
Therefore, the measure of ∠x is 64°

Nine years ago, Katie was twice as old as Elena was then.
Elena realizes, "In four years, I'll be as old as Katie is now!"
Elena writes these equations to help her make sense of the situation:
[tex]k-9=2(e-9)\\e+4=k[/tex]
If Elena is currently years old and Katie is years old, how old is Katie now?
Answer:
Given that Elena is currently e years old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.
So, k - 9 = 2(e - 9)
⇒ k - 2e + 9 = 0 .............. (1)
And, in four years, Elena will be as old as Katie is now.
So, k = e + 4
⇒ k - e - 4 = 0 ............... (2)
Therefore, the equations (1) and (2) matches the conditions. (Answer)

PLEASE SHOW YOUR WORK
Answer:
Step-by-step explanation:
1. A ticket at the NBA championship game costs $200 each. You will be given a discount of 8% if you buy early.
Your parents gave your $570
a) How much will you pay if you buy early.
$200 * 0.08 = $16 (how much you get off)
$200 - $16 = $184
This means that you will pay $184 for each ticket if you buy early.
b) Opps the tax is 4.5%.
4.5/100 = 0.045
$184 * 0.045 = $8.28 (how much you will be paying for tax)
c) How much will you pay including tax?
$184 + $8.28 = $192.28
d) How much will you pay for your two brothers?
You + your two brothers = 3 people
$192.28 * 2 = $384.56
Total for all 3 people: $192.28 + $384.56 = $576.84
e) Do you still have money for popcorn if your parents will give you $570.00?
The total cost of the tickets for you and your brothers is $576.84.
$576.84 is greater than $570.
So, no. You won't have money for popcorn.

150 centimeters
160 centimeters
1,500 centimeters
1,600 centimeters
Answer:
CORRECT OPTION IS 150 CENTIMETERS OR YOU CAN SAY 1.5M :)
Step-by-step explanation:
GIVEN:
Walt grew 10 cm in one year
He is now 1.6m
SOLUTION:
We know that 1 m = 100cm
So 1.6 m = 160cm
So one year ago he was:
160 - 10 = 150cm
So he was 150 cm or 1.5 m one year ago.

The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after θ seconds can be described by the function f of theta equals 2 times sine theta plus radical 2 period
Part A: Determine all values where the pogo stick's spring will be equal to its non-compressed length. (5 points)
Part B: If the angle was doubled, that is θ became 2θ, what are the solutions in the interval [0, 2π)? How do these compare to the original function? (5 points)
Part C: A toddler is jumping on another pogo stick whose length of its spring can be represented by the function g of theta equals 1 minus cosine squared theta plus radical 2 period At what times are the springs from the original pogo stick and the toddler's pogo stick lengths equal? (5 points)
Answer:
0
Step-by-step explanation:
So,0= the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.
Hence, the values for different conditions were calculated with the help of trigonometric functions.
Part A
θ=kπ
Where k is an integer k=0,1,2..
Part B
θ=[tex]k\frac{\pi }{2}[/tex]
Where k is an integer k=0,1,2..
Part C
θ=kπ
Where k is an integer k=0,1,2..
What is trigonometric function?The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths
Part A
Given that,
f(x)=2sinθ+[tex]\sqrt{2}[/tex]
Non compressed length = [tex]\sqrt{2}[/tex]
Then
2sinθ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]
2sinθ=0
sinθ=0
Therefore θ is the integer multiple of π
θ=kπ
Where k is an integer k=0,1,2..
Part B
Here angle is doubled
Then,
2sin2θ+[tex]\sqrt{2}[/tex]=[tex]\sqrt{2}[/tex]
2sin2θ=0
sin2θ=0
Here θ will be the integer multiple of [tex]\frac{\pi }{2}[/tex]
θ=[tex]k\frac{\pi }{2}[/tex]
Where k is an integer k=0,1,2..
Part C
g(x)=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]
Here
f(x)=g(x)
2sinθ+[tex]\sqrt{2}[/tex]=1-[tex]cos^{2}[/tex]θ+[tex]\sqrt{2}[/tex]
2sinθ=1-[tex]cos^{2}[/tex]θ
we know that [tex]1-cos^{2}[/tex]θ=[tex]sin^{2}[/tex]θ
2sinθ=[tex]sin^{2}[/tex]θ
sinθ=0
Therefore θ is the integer multiple of π
θ=kπ
Where k is an integer k=0,1,2..
Hence, we have solved that
Part A
θ=kπ
Where k is an integer k=0,1,2..
Part B
θ=[tex]k\frac{\pi }{2}[/tex]
Where k is an integer k=0,1,2..
Part C
θ=kπ
Where k is an integer k=0,1,2..
