Answer:

0.95

Step-by-step explanation:

Quarter = 0.25

Dime = 0.10

0.25+0.25+0.25= 0.75

0.10+0.10= 0.10

0.10+0.75 = 0.95

The function p(x) = 25x represents the number of pages p(x) a printer can print in x minutes. How many pages can the
Rashid [163]

Answer:

7,500 Pages

Step-by-step explanation:

So this printer can prink 25 pages in 1 (x) minute.

There are 60 minutes in an hour and we are waiting 5 hours, so 5x60 = 300 minutes.

Then you take the 300 and plug it in for x because that is how many minutes we are waiting for.  Now your equation should look like this:

p(x) = 25(300)

Next you multiply 25 x 300 and you get 7,500 pieces of paper

Answer:

They will be able to.

Step-by-step explanation:

You first want to make sure the first three families have enough to eat.

6\frac{1}{2} - 2\frac{7}{8} = 3\frac{5}{8}

For further explanation look at the first image.

3\frac{5}{8} > 2\frac{7}{8}

Just to make sure

3\frac{5}{8} - 2\frac{7}{8}=\frac{3}{4}

For further explanation look at the second image.

The rest of the images show a model solution.

Pls help!!! evaluate the function for x=m/4
EastWind [94]
Plug in m/4 into the equation:

8 (\frac{m}{4})^{2} - 4(\frac{m}{4})

Solve the parentheses in the equation:

\frac{m}{4}^{2} = \frac{m}{4} \times \frac{m}{4} = \frac{m^{2}}{16}
8 \times \frac{m^{2}}{16} = \frac{8m^{2}}{16} = \frac{m^{2}}{2}

4 \times \frac{m}{4} = \frac{4m}{4} = m

Your equation should now look like this:

\frac{m^{2}}{2} - m

The answer is D.

Una parte de 25 000 dólares se invierte al 10% de interés, otra parte al 12 % y el resto al 16%. El ingreso anual total de las t
Drupady [299]

Answer:

  • $5000 at 10%, $10000 at 12% and 10000 at 16%

Step-by-step explanation:

  • <em>One part of $ 25,000 is invested at 10% interest, another part at 12%, and the rest at 16%. The total annual income from the three investments is $ 3,200. Also, the income from the investment at 16% is equal to the income from the other two investments combined. How much was invested at each interest rate?</em>

==================

Let the parts be x, y and z

<u>As per given we get below system of equations:</u>

  • x + y + z = 25000
  • 0.1x + 0.12y + 0.16z = 3200
  • 0.1x + 0.2y = 0.16z

<u>Substitute 0.1x + 0.2y in the second equation:</u>

  • 0.16z + 0.16z = 3200
  • 0.32z = 3200
  • z = 3200/0.32
  • z = 10000

<u>Now we have:</u>

  • x + y + 10000 = 25000 ⇒ x + y = 15000

and

  • 0.1x + 0.12y + 0.16*10000 = 3200 ⇒ 0.1x + 0.12y = 1600

<u>Multiply the second equation and then subtract the first one:</u>

  • 10(0.1x + 0.12y) = 10(1600) ⇒ x + 1.2y = 16000
  • x + 1.2y - (x + y) = 16000 - 15000
  • 0.2y = 1000
  • y = 10000

Then

  • x = 15000 - 10000 = 5000

<u>So the parts are:</u>

  • $5000 at 10%, $10000 at 12% and 10000 at 16%
