In 2010 Elmbrook Middle School had 100 students in the eighth grade. In 2011 the number of eighth
graders decreased by 10%. The 2012 eighth grade Class increased in size by 10% from 2011. How many
eighth grade students were enrolled at Elmbrook Middle School in 2011

Answers

Answer:

90 students

Step-by-step explanation:

So, if you have 100 students to start and it decreases by 10% then take the 100 and multiply it by .10. You should get 10. Then, subtract 10 from 100 and you end up with 90.

Answer:

hello

2010 = 100 students

2011 = 100 x 0.9 = 90

2012 =  90 x 1.1 =  99

Arithmetic sequence is one derived from addition/subtraction of a constant term to find the next term. the constant term is usually called the common difference

first term a = 222

common difference, d = -5

nth term of an Arithmetic sequence. Tn = a + ( n - 1 ) d

T100 = a + ( 100 - 1 ) d

Answers

Answer:

0.25 x 132 = 33

Basket ball:?

33 + 33 + b = 132

66 + b = 132

Please rate and mark brainliest!!

Answer:

D.  66

Step-by-step explanation:

Total number of students = 132

If 25% of 132 students play tennis:

⇒ 0.25 × 132 = 33

So 33 students play tennis

Number of students who play basketball is: total number of students minus students play tennis minus students play lacrosse:

= basketball = 132 - 33 - 33 = 66

Let the angle of elevation of the ramp be θ, then:

[tex]\begin{aligned}&\sin \theta=\frac{1.5}{10}=0.15 \\&\theta=\sin ^{-1}(0.15) \approx 8.63^{\circ}\end{aligned}[/tex]

A square with side length s has an area of 324 square centimeters. This equation shows the area of the square ^{s^2}is 324

Answers

Answer:

s^2 = 324 would mean side length s = 18

Step-by-step explanation:

The square root of 324 would be 18.

A square with side length s has an area of 324 square centimeters. So, the side of the square is 18cm

What is the area of a square?

The area of a square can be calculated as the square of the sides of a given figure.

The area of a square = [tex]side^2[/tex]

A square with side length s has an area of 324 square centimeters.

The area of a square = [tex]side^2[/tex]

Answers

The probability that Harold selected a pink square tile, and either a red or a blue round tile is 1/9.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

Considering the selections are independent, their combined probability is the product of the probabilities of the individual events.

 P(pink square) = (pink squares) / (squares) = 16/60 = 4/15

 P(red or blue round) = (red or blue rounds) / ( rounds) = 15/36

Then, the Total probability

 P(E) = (4/15)(15/36)

 P(E) = 4/36

 P(E) = 1/9

So, the probability that Harold selected a pink square tile, and either a red or a blue round tile is 1/9.

The amount of time it takes for water to flow down a drainage
pipe is inversely proportional to the square of the radius of the
pipe. If a pipe of radius 1 cm can empty a sink in 22 seconds,
find the radius of the pipe that would allow the sink to drain
completely in 14 seconds.


PLEASE ANSWER FAST!

Answers

Using the proportional relationship, it is found that the radius of the pipe that would allow the sink to drain completely in 14 seconds is of 1.25 cm.

What is a proportional relationship?

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

If they are inverse proportional, the relationship is:

[tex]y = \frac{k}{x}[/tex]

In this problem, the amount of time is inversely proportional to the square of the radius of the pipe, hence:

[tex]t = \frac{k}{r^2}[/tex]

A pipe of radius 1 cm can empty a sink in 22 seconds, hence k = 22.

The radius for 14 seconds is:

[tex]t = \frac{k}{r^2}[/tex]

[tex]14 = \frac{22}{r^2}[/tex]

[tex]r^2 = \frac{22}{14}[/tex]

[tex]r = \sqrt{\frac{22}{14}}[/tex]

[tex]r = 1.25[/tex]

The radius of the pipe that would allow the sink to drain completely in 14 seconds is of 1.25 cm.

For the first question it's 52.99 cm^3 because the formula for volume of a cylinder is V=πr^2h.

The second question is 722.57 or 722 cm^2 because the formula for surface area is A=2πrh+2πr^2.

hope it helps!

Answer:

For question 3: 52.9875 cm^3 or 52.99 cm^3.

For question 4: 1,413 cm^3.

Step-by-step explanation: To find the volume of a cylinder, you need the area of the base times the height.  We don't have the area of the base, but we can find out by using the formula 3.14 x r^2 where r is the radius, which is 1.5 for question 3 and 5 for question 4.  It should look like this:

For question 3: 3.14 x 1.5^2 = 7.065.

For question 4: 3.14 x 5^2 = 78.5.

When you find the area of the base, you multiply it by the height, which is 7.5 for question 3 and 18 for question 4.  It should look like this:

For question 3: 7.065 x 7.5 = 52.9875 or 52.99.

For question 4: 78.5 x 18 = 1,413.

Therefore, 52.9875 cm^3 or 52.99 cm^3 is your answer for question 3 and 1,413 cm^3 is your answer for question 4.

Principal 'P' = $7000

Rate of interest 'r'= 3%

Time period 't' = 7years

Substitute the value in the formula to get total amount with interest,

[tex]Amount = 7000 [ 1+ (\frac{3}{100} )(7)][/tex]

             [tex]=7000[ 1+ (0.03)(7)]\\=7000(1.21)\\=8470 dollars[/tex]

Find the solution of the system of equations.
- 3x + 4y = 12
2.x + 2y = -22

Answers

Answer:

x = -8

y = -3

Step-by-step explanation:

So first you're going to want to get x or y by itself using elimination or substitution. I used elimination to get x by itself.

You can multiply the second equation (2x + 2y = -22) by -2 so you can eliminate the y's. When you multiply it, you get -4x - 4y = 44

Then, you can add -3x + 4y = 12 and -4x - 4y = 44. The y's cancel out to leave -7x = 56. Divide both sides by -7 to get x = -8.

Now, you can plug in -8 for x in either one of the equations. I plugged it into the second equation to make it 2(-8) + 2y = -22.

2 · -8 = -16.

-16 + 2y = -22. Add 16 to both sides to get 2y = -6. Divide both sides by to get y = -3.

Hope this helps! :)
