Answer: 145 cans
Step-by-step explanation:
arithmetic sequence
aₙ = a₁ + (n-1).r
aₙ → last term
a₁ → 1st term
n → quantity of terms
r → common difference
a₁ = 1 (one can at the top)
aₙ₋₁ = 25
aₙ = 28
To find out How many cans are in the entire display, we need the SUM of the arithmetic sequence: S = (a₁+aₙ)n/2
∴
S = (1+28).n/2
n = ?
aₙ = a₁ + (n - 1).r
r = 28 - 25 = 3
28 = 1 + (n - 1).3
27 = (n - 1).3
27/3 = (n - 1)
9 = n - 1
n = 9 + 1 = 10
S = (1+28).n/2
S = (1+28).10/2 = 29.10/2 = 29.5 = 145
Answer:
1/2 divided by 3 = 1/6
Step-by-step explanation:
I have half of a pizza and me and my 2 friend want to cut it equal between the 3 of us. How much do each of us get?
1/2 of a pizza cut into 3 equal pieces=1/6.
The value of 1/2 divided by 3 is 1/6. Let us find 1/2 divided by 3.
Explanation: Mathematically, we can write 1/2 divided by 3 as, 1/2 ÷ 3 = 1/2 × 1/3.
