Answer:

Q1:

150 pages is the answer

2 hours= 60+60minutes

So 120/40 =3

Answer= 50×3= 150.

Q2:

Using Work=men×days we get

Work=20×20

Work=400

Now, work is same and number of days are to be calculated

400=25×days

days= 16

400 = 25 x 16

so it will take 16 days

Step-by-step explanation:

Which of these division problems have the same quotient as 12.3 divided by 0.4? Check all that apply.

Orlov [11]

Answer:

The answer is A and C

Step-by-step explanation:

The answer is A because 12.3 multiplied by 10 is 123, and 0.4 multiplied by 10 is 4.

12.3 * 10 = 123

0.4 * 10 = 4

So, this shows that this equation is the same as 12.3 divided by 0.4

The answer is C because 12.3 multiplied by 100 is equal to 1230, this is the same for 0.4

12.3 * 100 = 1230

0.4 * 100 = 40

So, the answer is both A and C.

Hope this helps! :)

The graph of the revenue function f(x) = –0.07x2 + 3.5x is used to determine revenue in hundreds of thousands of dollars, where

Stells [14]

Answer:

$f(x) = -0.07x^2 +3.5x$

For this case since w ehave a quadratic function the mathematical domain would be:

$D =[x| x\in R]$

Where R represent the set of the reals. Now if we analze the reasonable domain we need to see that is impossible sold negative numbers of items so then the reasonable domain would be:

$D =[x \geq 0| x\in R]$

And the difference is that the reasonable domain takes all the positive values but the mathematical takes all the possible numbers

Step-by-step explanation:

For this case we have the following function given:

$f(x) = -0.07x^2 +3.5x$

For this case since w ehave a quadratic function the mathematical domain would be:

$D =[x| x\in R]$

Where R represent the set of the reals. Now if we analze the reasonable domain we need to see that is impossible sold negative numbers of items so then the reasonable domain would be:
