So this is a coordinate system so put it into y=mx+b format so 3y+2y=19 3y=19-2x Y=(-2x+19)/3 Y=-2/3x+19/3 19/3=6 and 1/3 So y=-2/3x+19/3 Put in values for x and y and get answers exg If you put in 3 For x then Y=-2+19/3 19/3=6 and1/3 -2+6 and 1/3=4 and 1/3 X=3 and y=4 and 1/3 (or 13/3)

A construction company is moving large rocks. It takes 3/4 hour to move 12 rocks. The construction company has already moved 60

Luden [163]

First divide the rocks per 3/4 of an hour by 3 and multiply by 4 to get the production per hour. then subtract the already moved rocks from the total job and divide the answer by 16 (the rocks moved per hour) getting the time needed to move the rest

A cylinder has a height of 12 inches and a radius of 1.5 inches. What is its voulme? Round your answer to the nearest tenth. Use

Lerok [7]

Answer:

It's volume is of 84.78 cubic inches.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder with radius r and height h is given by:

$V = \pi r^2h$

A cylinder has a height of 12 inches and a radius of 1.5 inches.

This means that $h = 12, r = 1.5$

What is its volume?

$V = \pi r^2h = 3.14(1.5)^2(12) = 84.78$

It's volume is of 84.78 cubic inches.

At sea level, earths atmosphere exerts a pressure of 1 atmosphere. Atmospheric pressure P (in atmospheres) decreases with altitu

PtichkaEL [24]

Answer:

Initial Amount=1

Decay Factor=0.99987

Decay Rate=0.013%

Step-by-step explanation:

If P = 0.99987ᵃ

I. Initial amount

The initial amount is when a=0

P = 0.99987⁰ = 1

The Pressure at Sea Level=1

II. Decay factor

This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.

III. Decay Rate = 1-0.99987 = 0.00013

Expressed in Percentage = 0.013%
