The distance between two points, a and b, on a number line is expressed as la-bl where a and b are rational numbers. Think about locating a point halfway
between a and b on a number line. How can you find the coordinate for such a point?

Develop a formula in terms of a and b that you can use to find the coordinate. Your
formula must work for positive and negative values of a and b. Does absolute value
play a role in your formula? Why or why not? Under what circumstances might your
formula be used in the real world? Explain
Discuss how you can find the coordinate of a point located other fractional distances
from a to b (or from b to a) For example locate a point three-fourths of the distance
from a to b. What kind or calculation is involved?

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

or

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
