Answer:
Step-by-step explanation:
1. volum of half cylinder + volume of the prism= (4.5*4.5*314)/2 + 9*11*6 = 31.7925 * 594 = 625.792
2. are or base (hex) * height =height* perimete* apothem /2 = 5*(8*6*6.9)/2 = 828
Answer:
= 18
Step-by-step explanation:
= 
Cross multiply
5 * c = 30 * 3
5c = 90
Divide both sides by 5
c = 90/5
c = 18
Answer:
b. 8
Step-by-step explanation:
12/30 = x/20
x = 12/30 × 20
x = 8
Your first point should always be shown in the y-intercept following the standard form for slope-intercept form
Y = mx + b
b = y - intercept
In this case your first point would be (0,1)
You next point would be following the slope which is -2x. When you graph a equation always know that it is rise over run. For this line, it would be going from left to right since it is a negative line.
Your second point would go down 2 points from your starting point (0,1) and run 1 to the right in the x-axis, which is also called, (1,-3)
