0.12 cubic meters of silver which she needs to make into 9.9e4 coins of thickness 2 mm. If she uses all of the silver, what is the diameter in centimeters of each coin

The diameter of each coin is approximately 2.778 centimeters.

Step-by-step explanation:

According to the statement, 0.12 cubic meters () were used to produce 99000 coins. First, we calculate the volume of each coin (), measured in cubic meters, by dividing the total volume by the number of coins. That is:

Then, diameter (), measured in milimeters, can be derived from the following volume formula:

(1)

Where is the thickness of the coin, measured in milimeters.

If we know that and , then the diameter of each coin is:

The diameter of each coin is approximately 2.778 centimeters.

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)
