What is the slope OF THE GRAPH, not what is A slope, what is THE slope
Oksanka [162]

Answer:

-3/1

Step-by-step explanation:

The slope can be found by putting the rise over the run.  

Pick 2 points on the graph that intercept the line.

I'll pick (0,2), and (1,-1)

Look at the rise.(How many places it goes up or down)

The rise vertical distance(rise), between the two points is -3.

Now look at the run(the horizontal distance.)  It's 1.

Rise/Run =  -3/1  AKA -3

A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product. How many gallons were made
iVinArrow [24]

Answer:

So, total gallons were made in all =9.31 gallons

Step-by-step explanation:

We are given

A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product

so,

first experiment =1.42 gallons

Second experiment =3.81 gallons

Third experiment =4.08 gallons

now, we can find total gallons

total gallons = first experiment + second experiment + third experiment

total gallons =1.42 gallons + 3.81 gallons +4.08 gallons

total gallons =9.31 gallons

Find the area of a circle with a circumference of 12.56 units
ElenaW [278]

Answer:

12.56 square units

Step-by-step explanation:

The formula for circumference is

C = 2πr

Our circumference is 12.56.  Using 3.14 for π, we have

12.56 = 2(3.14)r

12.56 = 6.28r

Divide both sides by 6.28:

12.56/6.28 = 6.28r/6.28

2 = r

The area of a circle is given by the formula

A = πr²

Using 3.14 for π and our radius of 2, we have

A = 3.14(2²) = 3.14(4) = 12.56.
