A wall is 300 square feet.a gallon of paint covers 110 square feet. What is an appropriate conversion factor to help determine h

saveliy_v [14]

Answer:

(1 gallon)/(100 ft^2)

Step-by-step explanation:

(1 gallon)/(100 ft^2) is a good conversion factor. We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:

(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.

elizabeth buys a circular rug with a lace border. the lace is 12.56 feet long what is the diameter of the rug

vfiekz [6]

We know that the lace is also what we would call the circumference of the circle.

And we also know that the circumference of a circle is represented by the equation: $c= \pi d$ .

We then can use the length of the lace (12.56 ft) to solve for the diameter (d) of the rug. Let us solve for that now:

$12.56=(3.14)d$

$d=4$

We now know that the diameter of the rug is 4 ft.
