4 + 12 + 36... etc
is a sum that can be rewritten in form
4 ( 1, 3, 9, 27, 81, etc) this can further be written in sigma notation:
4 Sigma [ 3 ^ ( i - 1)]
The sum of the indefinite summation will be the limit as i goes to infinity = infinity
You mean 23 is what percent of 16 right?
Well let's divide and multiply by 100.
23 / 16 = 1.4375 ≈ 1.440
1.440 * 100 = 144.0
Therefore 23 is approximately 144% (exact. 143.75%) of 16.
You can confirm by answer by multiplying 16 by 1.4375.
Answer:
c. 11
Step-by-step explanation:
3p + 10 = 2p + 21
Subtract 2p from both sides.
3p - 2p + 10 = 2p - 2p + 21
Simplify.
p + 10 = 21
Subtract 10 from both sides.
p + 10 - 10 = 21 - 10
Simplify.
p = 11
Answer: c. 11
Answer:
Rational
Step-by-step explanation:
The square root of 16 is 4, and 4 + 1.5 is = to 5.5. An irrational number is defined as infinite and never-ending. Since 5.5 is not infinite, we can conclude that it isn't irrational.
Answer:
4 is even; 4 can be divided by 2 and the quotient is whole.
Step-by-step explanation:
If a number is even, it can be divided by 2 and the quotient is a whole number. 4 can be divided by 2 and the quotient is whole, so we can say 4 is even.
