Answer:

7/12

Imagine this:

you had a block set with 12 blocks in it

you built a tower with 5 blocks (5/12)

You have 7 blocks left (7/12)

5/12 + 7/12 = 12/12 = 1

dsp73
Okay. so, to find the answer for this, you should set the equation as 10.25x = 8,425. "x" equals the number of hours. What you should do is divide each side by 10.25 to isolate the "x". When you do that 8,425/10.25, you get 821.951 and other numbers or 822 hours when rounded to the nearest whole number. x is approximately 822. You would have to work about 822 hours to earn $8,425.

Find the area of the polygon with E(-3,2), F(1,5), G(5,-1), H(1,-5).
kykrilka [37]

Answer:

40

Step-by-step explanation:

-3   2

               -15  -   2         =      -17

1     5

                 -1    -  25      =     -26

5<em> </em>   -1

                -25    -   (-1)   =     - 24

1   <em> -5</em>

                 2      -   <em>15</em>    =     -13

<em>-3</em>   2

area = |-17 - 26 - 24 - 13|/2 = |-80|/2 = 80/2 = 40

The profit P (in thousands of dollars) for an educational publisher can be modeled by P 52b31 5b21b where b is the number of wor
Anna007 [38]

Answer:

The lesser number of workbooks are 1,000

Step-by-step explanation:

The correct question is

The profit P (in thousands of dollars) for an educational publisher can be modeled by P=-b³+5b²+b where b is the number of workbooks printed (in thousands). Currently, the publisher prints 5000 workbooks and makes a profit of $5000. What lesser number of workbooks could the publisher print and still yield the same profit?

we have

P=-b^3+5b^2+b  

For P=\$5,000

substitute in the equation and solve for b

Remember that the profit and the number of workbooks is in thousands

so

P=5

5=-b^3+5b^2+b

Using a graphing tool

Solve the cubic function

The solutions are

x=-1

x=1

x=5

therefore

The lesser number of workbooks are 1,000

<u><em>Verify</em></u>

For b=1

P=-(1)^3+5(1)^2+1  

P=5  -----> is in thousands

so

P=\$5,000 ----> is ok
