Answer:
36.4% which is rounded down to 36%
Step-by-step explanation:
100 divided by 22 = 4.54545454545 (since the total amount is 22)
8*4.54545454545 = 36.3636363636 (since 8 people out of 22 finished)

What is x divided by x?
Answer:
its 1
Step-by-step explanation:
the value of x and x is like having 1÷1 = 1
same with x : x÷x=1
since x is just a value
When x is divided by x , it's 1.
What is division?Division is the process of splitting a number or an amount into equal parts.
Here, given that,
x is divided by x
=x/x
=1.

number three is 1 over 10 ok
Answer:
1) x = 4
2) x = -4
Step-by-step explanation:
1) -2x - 12 + 18 = 11 - 3x
-2x + 7 = 11 - 3x
x = 4
2) x - 23 = 8x + 12 - 7

A circle has the equation x + y + 18x-22y = -153. What is the length of the diameter of the circle?
Answer:
777y us or do we will miss because
The length of the diameter of the circle which the equation x + y + 18x-22y = -153 is 3.5 units long.
What is the equation of circle?The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.
The standard form of the equation of the circle can be given as,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Here (h,k) is the center of the circle and (r) is the radius of the circle.
The equation of the circle given as,
[tex]x^2 + y^2 + 18x-22y = -153[/tex]
Rearrange the equation to make it as standard form,
[tex]x^2 + y^2 + 18x-22y = -153\\x^2 + 18x+ y^2-22y = -153[/tex]
Add 121 and 81 both side of the equation,
[tex]x^2 + 18x+81+ y^2-22y+121 = -153+81+121\\x^2 + 18x+9^2+ y^2-22y+11^2 =41[/tex]
Using the formula of whole square,
[tex](x+9)^2+(x-11)^2=7^2\\(x-(-9))^2+(x-11)^2=7^2[/tex]
Compare it with standard equation, we get the radius of the circle r is 7.
As the radius is half of the diameter. Thus, the diameter of the circle is,
[tex]d=\dfrac{7}{2}\\d=3.5\rm\; units[/tex]
Thus, the length of the diameter of the circle which the equation x + y + 18x-22y = -153 is 3.5 units long.

Find the orthocenter of the triangle with the given vertices: L(2, 2), M(-4, 2), N(-2, 6) a (-2, 4) b (3, -5) c (2, -4) d (-3, 5)
9514 1404 393
Answer:
(a) (-2, 4)
Step-by-step explanation:
The orthocenter is the point of concurrence of the altitudes of the triangle.
A plot of the triangle vertices shows the triangle to be acute. That means the orthocenter is inside. This eliminates choices B, C, D, which are all points outside the triangle.
__
Conveniently, side LM is horizontal. This means the orthocenter will have the x-coordinate of the vertical line through N, which is -2. Only one answer choice has an x-coordinate of -2:

Nanette goes fishing. Of the fish Nanette catches, 2/3 are catfish. She catches 12 fish that are not catfish. Which equation and solution represent the total number of fish, x, Nanette catches?
Answer:
36 fishes
Step-by-step explanation:
Step 1
Nanette goes fishing. Of the fish Nanette catches, 2/3 are catfish.
Let the total fraction of fish = 1
The fraction of fish that is not catfish is
1 - 2/3
= 1/3
Step 2
She catches 12 fish that are not catfish.
Let the total number of catfish = x
Hence,
1/3 × x = 12
Equation is given as:
x/3 = 12
Cross Multiply
x = 3 × 12
x = 36 fishes
The the total number of fish, x that Nanette catches is 36 fishes

Step-by-step explanation:
Hello There!
A is not true because overall 22% had trucks of the 100 people while only 9% overall had a van. So more people overall had trucks then vans meaning that vans has the lowest percentage of type of vehicle driven therefore we can eliminate answer choice A
B is also incorrect because from ages 41-50, a total of 14 people drive a van or sedan. Also from ages 41-50, a total of 14 people drive a SUV or truck. Because the total of people that drive each of the grouped vehicles is the same neither of the percentages would be lower or higher therefore we eliminate answer choice B
C is also incorrect because the same amount of people in the age group 31-40 drive trucks as the amount of people in the age group 41-50. Because the same amount of people from the different age groups drive trucks the percentage would be neither higher nor lower therefore C is incorrect
D is the correct answer choice because the total amount of people that drive trucks from the age range 21-30 is the same as the amount of people that drive a truck from other age groups. Or to be more specific the sum of the people who drive a truck from ages 31-40, 41-50 and over 50 is 11 (3+4+4=11) This meaning that the same percentage of people in the age range from 21-30 that drive a truck is the same as the percentage of people that drive a truck from the sum of the other age ranges. Hence the correct answer choice is D

6 times what equals 84?
6 times what equals 84? In other words, what do you multiply by 6 to get 84? If "x" is "what" in the sentence, "6 times what equals 84?", then the equation to solve the problem is as follows:
6 • x = 84
Which can be written as:
6x = 84
To solve the equation above, we need to remove the 6 on the left side to make the x alone. To do that, we divide both sides by 6.
6x/6 = 84/6
6x/6 is x and 84/6 is 14 which means our equation will look like this:
x = 14
Thus, the answer to "6 times what equals 84?" is 14.
Answer:
14
Step-by-step explanation:
cause 84 divided by 6 is 14,then do 14 times 6 and its 84.

Mr. Mann asked his class to form a number pattern using the rules:
Use the number 6 as the first term.
To find the other term, subtract 2 from the previous term, then multiply by 2.
The first two numbers in the pattern are 6 and 8.
What is the fourth number in the pattern?
Answer:
20
Step-by-step explanation:
when you subtract 2 from 6 you get 4. so you multiply 4 into 2 which give the answer 8. when you subtract 2 from 8 you get 6 and then you multiply 6 to 2 which gives the answer 12... next you subtract 2 from 12 which gives the answer 10. so you multiply 10 to 2 Which gives the final answer for you which is 20.
