Answer:

Average speed is calculated by dividing distance by time (e.g. miles/hour). Okay we're going to talk about average speed, instantaneous speed is the distance that you're covering at a specific time. So 100 kilometers an hour, average speed is the total distance you're going to cover over a period of time.

Solve –2 + x > 10 using the properties of inequalities.

lys-0071 [83]

Using the properties of inequalities:
Subtract -2 from each side of the inequality    -2 + x > 10
Remember -2 - -2 becomes -2 + 2 = 0         <u>- -2 + x > --2
</u>10 - -2 becomes 10 + 2 =12<u />                             0 + x > 12
So the final solution would be x > 12.
Therefore x would have to be all numbers greater than 12.

A fencing company charges $22per foot to install a wood fence around a rectangular pool area that is 20 feet wide and 38 feet lo

pantera1 [17]

We will need to find the perimeter here, since in this context we’re talking about fencing around a rectangular pool. The formula for perimeter is P = 2L + 2W. The L and W can stand for length/width which is the same as wide/long in this problem. I will now plug in the numbers. P = 2(38) + 2(20) which gives us 76 + 40. 76 + 40 is 116. Therefore, the perimeter is 116 ft.

I know that the fencing company charges $22 per foot. I can multiply 116 x 22 to give me $2552. The answer is $2552.

A book publisher found that the cost to produce 1000 calculus textbooks is $26,300, while the cost to produce 2000 calculus text

andrew-mc [135]

Answer:

$26.60

Step-by-step explanation:

Calculation for the marginal cost of a calculus textbook

Marginal cost =($52,900-$26,300)/(2,000-1,000)

Marginal cost=$26,600/1,000

Marginal cost=$26.60

First step

$52,900=2,000x +c equation (1)

$26,300= 1,000x+c equations (2)

Second step is to subtract equation (1) from equation (2)

$52,900=2,000x +c equation (1)

-$26,300= 1000x+c equations (2)

$26,600=1,000x

Third step is to find the marginal cost

$26,600=1,000x

x=26,600/1,000

x=$26.60

Therefore the marginal cost of a calculus textbook will be $26.60
