Answer: ok heres an example 
 5÷50
first you say to yourself what times what is 5 then you know 1x5=5 so in the = you put 1 for now. then you see what times 5 is 0 its 0×5. then you subtract 0-0 and it gives you 0. then in the  = sign you have =5 then you add a 0 wich makes =50 so 50 is the anwer

The one cost DVD is 16.98, and the cost of another DVD is 9.29. Ed estimated the cost of the two DVD to be about 27. Is his estimate higher or lower than the actual cost? Explain

Answers

Answer:

Higher

Step-by-step explanation:

16.98 + 9.29 = 26.27 < 27.00

26.27 is rounded to 26.10 or 26.00 so Ed's estimate is higher

Hope this helps

What is 480 increased by 25%.
what is the new number?

Answers

The new number is 600.How do we get 600? Here’s how:
 1. First, we have to get the 25% of 480.
      Multiply 480to 25%.
                   480x 25%= n
Change 25% to decimal form.
                   25/100(as per value of % symbol)
                   25% is 0.25So, 480 x 25% = n is:
                 480x 0.25 = 120
  2.  Add 25% of 480 (120)and 480.
                480 + 120 =600
 Therefore, when 480 is increased by 25%, it is 600.  


480 * 25%480 * 0.25480 * 0.25 = 120480 + 120 = 600.480 increased by 25% is 600

The function y=3.5x+2.8 represents the cost in y ( dollars ) of a taxi ride of x miles. You have enough money to travel at most 20 miles in the taxi. Find the domain and range of the function. I don't understand how to get both the domain and range at the same time.

Answers

Answer:

Step-by-step explanation:

The domain of a function is the set of elements for which the function is defined. In other words, the domain is the range of values ​​of x for which the function exists, that is, it has a result.

"x" in this case represents the number of miles traveled by taxi. If the passenger has enough money to travel a maximum of 20 miles, the domain will be:

Domain = {0 ≤ x ≤ 20}

On the other hand, the image is the range of values ​​of the function for which there is a value of x. In other words, it is the set of values ​​of the variable "y" that is obtained when evaluating in the function all the possible values ​​of x.

In this case the function "y" is evaluated at both ends to determine the range of variation of the image:

In x=0 → y=3.5*0 + 2.8 → y= 2.8

In x=20 → y=3.5*20 + 2.8 → y= 72.8

So,the range of the function is between $2.8 and $72.8

Range = {2.8 ≤ y ≤ 72.8}

A plane at an altitude of 20000 feet starts to descend for landing after flying for six hours. The entire flight time was 6 hours 40 minutes. Determine the average rate of descent of the plane

Answers

Check the picture below.

so, let's see, the plane departs from (0, 0), the origin, goes up to 20000 feet, sticks around flying for 6 hours, 6hrs = 3600 minutes, (6*60).

so the plane's descent starts off at the point (3600, 20000) down to (3640, 0) as you see in the picture, keeping in mind that average rate of change = slope.

\bf (\stackrel{x_1}{3600}~,~\stackrel{y_1}{20000})\qquad (\stackrel{x_2}{3640}~,~\stackrel{y_2}{0}) \n\n\n slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{0-20000}{3640-3600}\implies \cfrac{-20000}{40} \n\n\n \cfrac{-5000}{1}\cfrac{ft}{minute}\implies -5000(ft)/(min)

the slope is negative, since it's a descent, the plane is coming down, not going up over the minutes axis.

Answer: 500 feet per minute

Step-by-step explanation:

Landing time 40min with an altitude of 20000 remaining

40=20000 | both sides /40

1=500

Complete the square x^2+x+8x

Answers

Answer:

x^2+x+8x=(x+(9)/(2) )^2-(81)/(4)

Step-by-step explanation:

The given expression is x^2+x+8x

To complete the square, we first simplify the function to get:

x^2+9x

Add and subtract the square of half the coefficient of x

x^2+9x+((9)/(2) )^2-((9)/(2) )^2

The first three term is a perfect square (x+(9)/(2) )^2-(81)/(4)
