Answer:
V=πr2h
/3
V=πr2h
/3=π·2.52·8
/3≈52.35988
so the volume is 52.36 inches
Answer: No, he is not correct
The number of combinations is 190
============================================================
Work Shown:
We have 10 shirts, 6 hats, and 4 scarves. This is 10+6+4 = 20 items total.
If we randomly pick out an item, then we have 20 to choose from. After selecting that first item, we have 20-1 = 19 items left to choose from.
So there are 20*19 = 380 different permutations. Order matters with permutations.
Since we aren't worried about order, this means that we've double counted so we have to divide by 2 to fix it.
So there are 380/2 = 190 combinations.
You can use the nCr combination formula with n = 20 and r = 2 to get the same result.
Red line
slope m = 1/4
y=(1/4)x+b
b is y-intercept, b=1
y=(1/4)x+1
To get it the for that are given in the problem multiply both sides by 4.
4y=x+4, or x-4y=-4 red line
blue line
slope m=-3/4
y-intercept b= 9
y=-(3/4)x+9
4y=-3x+36
3x+4y=36 blue line
x-4y=-4 red line
3x+4y=36 blue line

We are given statement : The distance between Pittsburgh, Pennsylvania, and St. Louis, Missouri, is 17 miles less than 5 times the distance between Pittsburgh and Cleveland, Ohio.
The distance between Pittsburgh and Cleveland = d.
We need to write an expression for distance between Pittsburgh and St. Louis.
And it's "17 miles less than 5 times the d".
5 times of d is = 5d.
17 miles less than 5d = 5d -17.
Therefore, 5d -17 expression can you use to represent the distance between Pittsburgh and St. Louis.
