During the birthday 4/7 of the cake was eaten so it remained 1-4/7=3/7
the next day 1/2 of 3/7 was eaten what remained is 3/7 divide by 1/2
to divide we invert the second fraction (1/2) and multiply 3/7
3/7 x 2/1=6/7
Answer:
Step-by-step explanation:
6x6=30 4x4=16 6x4=24
30+16+24= 70 inches square
Your problem statement is missing the formula Carrie came up with. It should be The one she started with, divided by m.
... G/m = a
For the values given, the acceleration is
... (7.92 N)/(3.6 kg) = 2.2 m/s²
_____
The unit of newtons is abbreviated N.
1 N = 1 kg·m/s² so dividing by kilograms leaves units of m/s², which are the units of acceleration.
Very likely, your question is not concerned with the units, just the number: 2.2. It's a straight division problem, easily handled by hand, by calculator, or in your head (after you realize 7.92 = 7.2×1.1 = 2×3.6×1.1).
Answer:
It is proved that if
is even the n is even.
Step-by-step explanation:
Given n is any integer.
To show
is even then n is even.
Proving by contrapositive suppose
is odd. Then we need to show n is odd.
Then, letting k is a ny integer,
Now since (2k+1) is odd therefore n is odd.
Conversly let n is odd, then,

since 2k+1 is odd so
is odd.
This proves, if n is even then
is even.
I know this is not the answer but how do you add a question
