What are 2 points on the graph for 6x-5y=25
zepelin [54]
To find any two random point on the graph of 6x-5y=25, we can just plug in any two values for x and solve for y, and find the 2 points in the form of (x,y).

So lets plug in x=0.

\sf 6x-5y=25
\sf 6(0)-5y=25
\sf -5y=25
\sf y=-5
So one point is (0,-5)

And to find another point, we can plug in x=1

\sf 6x-5y=25
\sf 6(1)-5y=25
\sf 6-5y=25
\sf -5y=25-6
\sf -5y=19
\sf y=19/-5
\sf y=-3.8
So another point is (1,-3.8)

A cylinder has height of 10 millimeters and radius 12 millimeters.Find the a.volume and b. surface area.
Sholpan [36]

Answer:

A. <u>Volume = 4,523.9 mm³ (cubic mm)</u>

B. <u>Surface area = 1,658.76 mm² (square mm)</u>

Step-by-step explanation:

A. Lest's calculate the volume of the cylinder:

r = 12 mm, h = 10 mm

Volume = π * r² * h

Volume = 3.1416 * 12² * 10

Volume = 3.1416 * 144 * 10

<u>Volume = 4,523.9 mm³</u>

B. Let's calculate the surface area of the cylinder:

Surface area = 2π * r * h +2π * r²

Surface area =2π * 12 * 10 + 2π * 12²

Surface area = 6.2832 * 120 + 6.2832 * 144

<u>Surface area = 753.98 + 904.78 = 1,658.76 mm²</u>

How high would a 2 story building be?
masha68 [24]
This would definitely vary but if I were to say I would probably think each story would be about 10 feet so it so 2 stories should be about 20 feet. but keep in mind that every building is unique.
