-- Start with 86.
-- Subtract 9 the first time. You have 77 left.
-- Subtract 9 the 2nd time. You have 68 left.
-- Subtract 9 the 3rd time. You have 59 left.
-- Subtract 9 the 4th time. You have 50 left.
-- Subtract 9 the 5th time. You have 41 left.
-- Subtract 9 the 6th time. You have 32 left.
-- Subtract 9 the 7th time. You have 23 left.
-- Subtract 9 the 8th time. You have 14 left.
-- Subtract 9 the 9th time. You only have 5 left, so you can't subtract 9 again.
You subtracted it 9 times, and you have 5 left.
So 86 divided by 9 is (9 with remainder 5) .
Let's say the numbers are "a" and "b"
thus
set the derivative to 0, and check the critical points, there's only one anyway
and do a first-derivative test, to see if it's a maximum
Answer:
68.6 Trips
Step-by-step explanation:
2.5m+1.5m+1.0=5
5m per trip
7m^3=343
divide the amount that can fit in each trip (5m)
by the amount of sand needed for the sculpture. (343m)
343 /5=68.6
Answer:
x= -3/5
Step-by-step explanation:
4x-2y=14
y=12x-1
4x-2(12x-1)=14
4x-24x+2=14
4x-24x=12
-20x=12
×= -12/20
x= -3/5
Answer:
n(B') = 15
Step-by-step explanation:
Assumunin U is the universal set.
B = { 7,11,17,19}
B' = natural numbers different form 7,11,17 and 19 = {1,2,3,4,5,6,8,9,10,12,13,14,15,16,18}
