Answer:
x = y
Step-by-step explanation:
x/3 + x/6 = 7/2
2x + x = 21
3x = 21
(divide 3 on both sides)
x = 7
1/25 of a minute is 2,4 secs.
1/5 = 2,4s
5/5 = 12 secs
Answer: 1326 students won't come to school
Step-by-step explanation:
All you have to do is find out 85% of 1560 which is 1326 students!
Because the polynomial has degree 2, we can assume that there are 2 solutions (roots), whether real or imaginary.
You can subtract 60 in order to put this in standard form
48x^2+44x-60 = 0
From there, just put a,b, and c into the quadratic formula and you're good to solve for your answers.
(-b+-sqrt(b^2-4ac))/2a
(-44+-sqrt(44^2-4(48)(-60)))/2(48)
Then solve.
There is probably a better way, but this should give you the two roots/solutions.
Formula for volue of cylinder is area time height. Lets find area
A=
diameter=2r
8=2r
r=4
Now substitute r to
A=
Now we have formula
V=
- its the result, so B
