This is a 20% increase. If we divvy up the 25 into 5 groups, we can say that each group is 20%. since we added another group of 5, we can go off of our known values and say that this was a 20% increase.
I answered C for that question.
F(x) = 2(x)^2 + 5 * sqrt(x + 2)
f(2) = 2(2)^2 + 5 * sqrt(2 + 2)
f(2) = 2 * 4 + 5 * sqrt(4)
f(2) = 8 + 5 * 2
f(2) = 8 + 10
f(2) = 18
1)85%
2)8/9
3).92
There is the answers
Step-by-step explanation:
the number divisible by 3 is the digit add together can divisible by 3.
778 is 7+7+8=22 (can't divisible by 3)
339 is 3+3+9=15 (can)
483 is 4+8+3=15 (can)
2747 is 2+7+4+7=20 (can't)
829 is 8+2+9=19 (can't)
438 is 4+3+8=15 (can)
51.979 (can't) because it isn't intiger number.
1116 is 1+1+1+6=9 (can)
...
So 339 483 438 1116 1857 57 3417 divisible by 3.
