iVinArrow [24]

She can make 4.

Explanation:

First you gotta find the circumference of the circle which is 37.68

Circumference=Diameter•pi

Pi is 3.14 in case you didn’t know.

Now divide the amount of ribbon she has by the circumference and you get 4.77…

So to make it simple we just say 4 because she wont want to make 4 and a half invitations.

Lee works at a job where her pay varies directly with the number of hours she works. Her pay for 6.5 hours is 49.40. Write a dir

puteri [66]

X = pay and y = hours worked
direct variation equations are of the form:
dependent variable = k(independent variable)
we need to find k, the constant of variation
x = ky
49.40 = 6.5k
7.6 = k
EQUATION: x = 7.6y
PAY for 25 hours: x = 7.6(25) = 190 or $190
