Emma created the poster shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 36 cm, and

the width is labeled as width equal to 24 cm. What would be the dimensions of the poster at fraction 1 over 4 times its current size? Length = 32 cm, width = 20 cm Length = 40 cm, width = 28 cm Length = 144 cm, width = 96 cm Length = 9 cm, width = 6 cm

Answer:

Length = 9 cm, width = 6 cm

Step-by-step explanation:

If the length of the rectangle is labeled as length equal to 36 cm, and the width is labeled as width equal to 24 cm.

Length = 36cm

Width = 24cm

One fourth the current size of the rectangle will be;

New length= 1/4×36 = 9cm

New width = 1/4 × 24 = 6cm

The new dimension of the poster is therefore 9cm×6cm

Length = 9cm

Width = 6cm

ehidna [41]

Answer:

Population after 16 year = 927 people (Approx.)

Step-by-step explanation:

Given:

Decrease rate = 10% per year

Current population = 5,000

Find:

Population after 16 year

Computation:

A = P[1-r]ⁿ

A = 5,000[1-0.1]¹⁶

A = 5,000[0.9]¹⁶

A = 5,000[0.1853]

A = 926.51

Population after 16 year = 927 people (Approx.)

does anybody know how the answer to this looks?
Varvara68 [4.7K]

Answer:

when x>2 (x= 3)

f(x) = -(x-2)² +1

when x = 3

f(3) = -(3-2)²+1

f(3) = -(-1)²+1

f(3) = -1+1

f(3) = 0

taking lesser value of x

makes f(x) increase

and when x>1

(x=2)

Now let's take x = 2

f(2) = -(2-2)²+1

f(2)= -(0)²+1

f(2)= 0+1 = 1

Therefore the values of x that makes f(x) = -(x-2)²+1 to increase are are (x>2 and x>1)

Please explain how to solve this problem

Answer:

  • 100 pounds Earl Grey
  • 300 pounds Orange Pekoe

Step-by-step explanation:

Let x represent the number of pounds of Earl Gray tea in the mix. Then the total cost of the mix is ...

  6x +4(400-x)=4.50(400)

  2x +1600 = 1800 . . . . . . . simplify

  2x = 200 . . . . . . . . . . . subtract 1600

  x = 100 . . . . . . . . . . . divide by 2. Pounds of Earl Grey

  (400 -x) = 300 . . . . . Pounds of Orange Pekoe

The blend should have 100 pounds of Earl Grey and 300 pounds of Orange Pekoe.

_____

<em>Additional comment</em>

It is easy to show that the relationship between the quantities of high-cost (H) and low-cost (L) items in the mix (M) is ...

  fraction of mix that is H is (M -L)/(H -L)

Here, we have H=6, L=4, M=4.5, so the fraction of the mix that is Earl Grey is ...

  (4.5 -4)/(6 -4) = 0.5/2 = 0.25

There are 400 pounds of mix, so 0.25(400) = 100 pounds is Earl Grey.

The solution above is essentially 2-step, so using this relation doesn't necessarily save any steps. It just makes it possible to solve the problem in your head.

Maria needed school supplies to complete here digital learning day lessons. She ordered pencils and paper from Wal-mart. She spe
son4ous [18]

Answer:

5x + 4($1.5) = $12.25

Step-by-step explanation:

Since we know that the paper is $1.50 per package and she bought 4 packages of paper, then she spent a total of $6 on the paper. Which leaves ($12.25-$6) $6.25 that she spent on buying 5 pencils. Now the cost per pencil can be derived by dividing $6.25/5, which is $1.25. Each pencil is $1.25.

The equation that can be used is the following where the cost per pencil is represented by x:

5x + 4($1.5) = $12.25
