Please i need this done

if Petra uses a scale of 1 in = 50 miles, the distance of 400 miles would fit in the page.

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling.

Scaling is essentially multiplying or dividing by a constant factor. We use scaling when representing geographic locations on a map.

Petra has a piece of paper that is 8.5 inches wide and 11 inches long and she wants to represent a distance of 400 miles by using the scale factor of 1 inch= 20 miles.

a)

Dividing the real distance by the scale factor we get 400/20 = 20 inches. Petra would need 20 inches of paper to represent the scaled distance. That distance won't fit in any direction of the paper, so she actually cannot make the scale drawing.

b)

To make the drawing, the distance of 20 inches should fit into the page in any orientation, let's assume it's done across the paper's width of 8.5 inches.

Dividing 400 / 8,5 = 47

This gives us an idea of the appropriate scale factor. We can use a round number like 50. Thus, if Petra uses a scale of 1 in = 50 miles, the distance of 400 miles would fit in the page.

what does x eaqual

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
