Answer:
30 pencils
Step-by-step explanation:
Given :
Number of pencils shared = 40
Sharing ratio = 2 : 6
Nimah's share = (2 / sum of ratio) * number of pencils
Nimah's share = (2 / 8) * 40
Nimah's share = 80 / 8
Nimah's share = 10 pencils
Jack's share = total number - Nimah's share
Jack's share = 40 - 10
Jack's share = 30
Answer:
61.12 units²
Step-by-step explanation:
(½ × pi × r²) + (½ × b × h)

Answer:</h2>
<u>The balance after 21 months is </u><u>$9960</u><u>.</u>
<h2>
Step-by-step explanation:</h2>
Let a₁ = 14760, a₂ = 14520, and a₂₁ be the balance after 21 months:
So we apply the given values to get the missing values:
First, we get the common difference, That is,
d = a₂ - a₁
d = 14520 - 14760
d = -240
So, we substitute the value of common difference and the known values,
a₂₁ = a₁ + (n-1)d
a₂₁ = 14760 + (21-1)(-240)
a₂₁ = 14760 + (20)(-240)
a₂₁ = 14760+(-4800)
a₂₁ = 9960
Therefore, the balance after 21 months is $9960.
B, With communtative property; you can switch the numbers around and the answer stays the same.
Example , 2 + 3 = 5 and 3 + 2 = 5.
They’re just in a different order
