360/45 = x/60

45n = 60

n = 60/45

n = 1.333 or 1 and 1/3

multiply the numerator by the same amount as the denominator

360 multiplied by 1.333 = 480

480parts/hour

Whats an equation for (0,75) (7,40) in slope intercept form

Molodets [167]

The slope-intercept form: y = mx + b.

m - slope, b - y-intercept

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (0, 75) → y-intercept (b = 75), and (7, 40).

Substitute the coordimates of the points to the formula of a slope:

$m=\dfrac{40-75}{7-0}=\dfrac{-35}{7}=-5$

<h3>Answer: y = -5x + 75.</h3>

Answer:

See below

Step-by-step explanation:

So basically the product is the result of mulyplying ---> factor × factor = product. You need to replace the values given so basically

8 ×2/5(0.40) =3.2 which is between 0 and 8, making the first statement true. Hopefully, this gives you an idea on how to answer the rest!!
