Answer:
C. 20
Step-by-step explanation:
p -4 = 16
p -4 + 4 = 16 + 4
p = 20
The slope is Y=5/3x.
A good trick to use to find the slope is count how high and how far you must go from one point to another to find the slope. (Rise over Run)
Answer:
About 12 minutes
Step-by-step explanation:
2/3 = 0.666666667
0.67/1 = 8 min/x min
Cross multiply:
8•1=8
8 divided by 0.6666667 = 11.9999994
Answer:A cylinder is a simple geometric shape with two equally-sized and parallel circular bases. Calculating the volume of a cylinder is simple once you know the formula.
Step-by-step explanation:
Answer:
If we have a cone-shape candle with r=2 cm and h=3 cm, then the amount of paper needed is 18.84 cm^2 and the amount of plastic needed is 12.56 cm^2.
Step-by-step explanation:
<em>The question is incomplete: no numerical values for the dimensions of the cone are given.</em>
<em />
A right cone is defined by the radius r of the base and the height h.
The base area is the area of a circle with radius r:
![A_b=\pi r^2](https://tex.z-dn.net/?f=A_b%3D%5Cpi%20r%5E2)
The lateral area is calculated as:
![A_l=\pi \cdot r\cdot l](https://tex.z-dn.net/?f=A_l%3D%5Cpi%20%5Ccdot%20r%5Ccdot%20%20l)
As the values for r and h are not given, we will use an example with r=2 and h=3.
Then, the amount of paper needed is:
![A_l=\pi \cdot r\cdot l=3.14\cdot (2\,cm)\cdot (3\, cm)=18.84\,cm^2](https://tex.z-dn.net/?f=A_l%3D%5Cpi%20%5Ccdot%20r%5Ccdot%20%20l%3D3.14%5Ccdot%20%282%5C%2Ccm%29%5Ccdot%20%283%5C%2C%20cm%29%3D18.84%5C%2Ccm%5E2)
The amount of plastic needed is:
![A_b=\pi r^2=3.14\cdot (2\,cm)^2=3.14\cdot 4\,cm^2=12.56\,cm^2](https://tex.z-dn.net/?f=A_b%3D%5Cpi%20r%5E2%3D3.14%5Ccdot%20%282%5C%2Ccm%29%5E2%3D3.14%5Ccdot%204%5C%2Ccm%5E2%3D12.56%5C%2Ccm%5E2)
