Answer:
121.9
Step-by-step explanation:
1 lb = .453kg, so you can multiple 268.8 and .453 to get your answer.
You already have all you need. Just put in it the slope-intercept form: y=mx+b where m is the slope and b is the y-intercept so
y=7x-4
The 105 per hour mechanic worked for 10 hours and the other worked for 15. here's the math.
so we know that each m&m weighs about 2g.
the next line says to write a direct variation equation.
(definition: mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other)
we then make the equation ( w=xm), then we use that equation to figure out the next line, which is to find the amount of m&ms that would fit in a bag of 1000.
(my head cant really process part a cause of a recent headache, so sorry if its wrong)
the answer to part b would be 500, which you can provide evidence based off of your part a equation.
i think the answer is 1.6*10^-3
