In 10 seconds -radius is 0.5 inches

in y seconds - radius is 1.25 inches

now using cross multiplication method

10 x 1.25 =0.5 x y

y= (10 x 1.25)/0.5

y = 25 seconds

hailstone should be 25 seconds long in the cloud to have a radius of 1.25 inches.

Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify points

Point (0, 2)

Point (3, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{2 + 3}{0 - 3}$
Simplify: $\displaystyle m = \frac{-5}{3}$

A bicycle store costs $2250 per month to operate. The store pays an average of $40 per bike. The average selling price of each

lesantik [10]

Answer:

Step-by-step explanation:

Given That :

Operation cost = $2250 per month

Purchase price per bike = $40

Average selling price per bike = $70

How many bicycles must the store sell each month to break even ;

Break even point = point at which there is net profit / loss = 0

Let number of bicycles store must sell = x

Operation cost + (purchase price * Number of bicycles) = selling price * Number of bicycles

2250 + 40x = 70x

2250 = 70x - 40x

2250 = 30x

x = 2250 / 30

x = 75

To break even 75 bicycles must be sold
