Answer:

2,200 students

Step-by-step explanation:

To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

\frac{students}{teachers}= \frac{900}{45}=\frac{x}{110}

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.

900(110) = 45(x)

99,000=45x

2,200 = x

Help ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
natali 33 [55]

Answer:

A Swedish court said Friday that rapper ASAP Rocky will be detained for another week as prosecutors decide whether to formally charge him following a fight last month in downtown Stockholm.

The rapper, born Rakim Mayers, has been in Swedish custody, along with two of his associates, since early July after a June 30 altercation that Rocky’s supporters say he tried to avoid. Under the court’s decision Friday, the men could be detained until at least July 25.

Concerns have mounted for the men amid reports that they are being held in “inhumane conditions,” including long daily periods of solitary confinement. A growing number of lawmakers and celebrities, including Kim Kardashian and Kanye West, has called for their release.

If you need $3,000 four years from now, how much would you need to deposit into an account that earns 5% interest, compounded an
Aleks04 [339]

Answer:

2468.11 dollars

Step-by-step explanation:

Amount that should be available after four years =3000 $

Interest rate = 5%

No of years =4

Let P be the principal invested

Then 3000=P(1+0.05)^4\\P=3000(1.05)^{-4} \\=2468.11

Hence 2468.11 dollars should be deposited to get 3000 dollars after 4 years at 5% interest.

A home gardener estimates that 18 apple trees will produce an average yield of 80 apples per tree. But because of the size of th
aliina [53]

19 trees should be planted to maximize the total

<h3>How many trees should be planted to maximize the total</h3>

From the question, we have the following parameters:

Number of apples, x = 18

Yield, f(x) = 80 per tree

When the number of apple trees is increased (say by x).

We have:

Trees = 18 + x

The yield decreases by four apples per tree.

So, we have

Yield = 80 - 4x

So, the profit function is

P(x) = Apples * Yield

This gives

P(x) = (18 + x) *(80 - 4x)

Expand the bracket

P(x) = 1440 - 72x + 80x - 4x^2

Differentiate the function

P'(x) = 0 - 72 + 80 - 8x

Evaluate the like terms

P'(x) = 8 - 8x

Set P'(x) to 0

8 - 8x = 0

Divide through by 8

1 - x = 0

Solve for x

x = 1

Recall that:

Trees = 18 + x

So, we have

Trees = 18 + 1

Evaluate

Trees = 19

Hence, 19 trees should be planted to maximize the total
