Answer:
343
Step-by-step explanation:
L×W×H= area
squares have equal L W And H
7×7×7= 343
The equation says
A=p(1+r)^t
A=103(1+0.02)^t
So the interest rate is
0.02*100=2%
You use 1 gallon is equal to 8 pints
Step-by-step explanation:
Initially, there's only 1 letter.
Tania sends the letter to 4 friends.
Each friend sends a letter to 4 more friends (4 × 4 = 16).
Each of those friends sends to 4 more friends (16 × 4 = 64).
The pattern is 1, 4, 16, 64, etc.
This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.
a₁ = 1
aₙ = 4 aₙ₋₁
The explicit formula is:
aₙ = 1 (4)ⁿ⁻¹
