Answer:
a. 40000pi ft^3
b. 5 times
Step-by-step explanation:
a. the volume of a cylinder is pi * h * r^2
r = 20ft, h = 100ft
so V = pi * 100 * 20^2 = 40,000pi or around 125663.7 ft^3
b. to find the number of times, divide the volume by the amount of salt needed per storm then round down:
40000pi/21000 = 5.98 so 5 times. notes: depending on the teacher you might just round to the nearest integer
Answer: 
Step-by-step explanation:
For a line to be parallel to another, it must have an equivalent slope. The equation, 
, is in slope-intercept form. Thus, the slope of both lines must be -1/7. Then, using the slope-intercept formula, plug in 7 for x and 21 for y to get:
Thus, the slope of the line is: .
Hope it helps :D
Answer:
0.375
Step-by-step explanation:
Here, we want to write the fraction given in its decimal form
What we have is 3/8 and we want to make it a decimal
Mathematically, that would be;
3/8 = 0.375
= 0 [ apply 
rule ] as 0 divided by any number will equal to 0 and has meaning.
= undefined. [ apply 
= undefined rule ] as the expression has no meaning. any number divided by 0 is undefined.
