Acheetah runs 300 feet in 2.29 seconds. how would you convert the cheetahs speed to miles per hour?

plain and short, an hour has 60 minutes, and a minute has 60 seconds, therefore an hour has 60*60 or 3600 seconds, and we can express that  rate as hr/3600s or the other way around 3600s/hr, depending on which version we need.

a mile has 5280 feet, again, we can use that rate as mile/5280ft or 5280ft/mile, as needed.

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
