4.8

Step-by-step explanation:

6 / (5/4) = 4.8

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

6 x 4 /5 = 24 /5

Thus, the answer to 6 divided by 5/4 in fraction form is:

24/5

To make the answer to 6 divided by 5/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

24 / 5 = 4.8

The answer is rounded to the nearest two decimal points if necessary.

24/5 is an improper fraction and should be written as 4 4/5.

answer: it's d

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
