Answer:
the company must buy 22 gallons to paint this entire area
Step-by-step explanation:
The circumference of the tank is given and is C = 2(pi)r, where r is the area.
118 ft
Here the circumference is C = 2(pi)(r) = 118 ft, which leads to r = ------------ ≈
18.79 ft ≈ r 2(pi)
The area of the sides is A = (circumference)(height), or approximately
(118 ft)(50 ft) = 5900 ft², and the area of the top is A = πr², which here comes to (π)(18.79 ft)² ≈ 1109 ft². Combining these two sub-areas, we get:
A(total) = 1109 ft² + 5900 ft² ≈ 7009 ft²
To determine how many gallons of paint will be needed to paint only the top and sides, we divide 7009 ft² by the coverage rate, which is
320 ft²
-----------
1 gallon
which results in:
7009 ft²
---------------------- ≈ 21.9 gallons
320 ft² / gallon
Since the paint comes only in full gallon cans, the company must buy 22 gallons to paint this entire area.
Answer:
The Y intercept would be 1. The slope would be 2.
Step-by-step explanation:
The Y intercept is where a line intercepts, or crosses the Y axis. As you can see in the graph, the line crosses the Y axis at point 1.
To find slope here, you can do the rise divided by the run.
To find this, choose two points. We can use point (0, 1) and point (1, 3)
Next, find the rise, or the vertical distance between the two points. In this case, it would be 2.
Then, find the run, or the horizontal distance between the two points. In this case, it would be 1.
Finally, divide the rise by the run, and create the fraction rise over run, or in this case 2/1.
