Answer:
8:16, 8 actions films
Step-by-step explanation:
1:2 = 1x:2x
= 24 / (1x+2x)
= 24 / 3x = 8, x = 8
= 8*1 : 8*2
= 8:16
Proof:
8 + 16 = 24
The merchandise shop sells 80 CDs for every 1 vinyl record. We have to find how many vinyl records they are likely to sell if the merchandise shop sells 760 CDs:
80 CDs -------------------- 1 vinyl record
760 CDs --------------------- x vinyl records
---------------------------------------------------------
80 : 760 = 1 : x
80 x = 760
x = 760 : 80
x = 9.5 or 9 ( we need a whole number )
Answer: They are likely to sell 9 vinyl records.
The answer is 10. 2 and 5 are not divisible by the same number except one, so you multiply it by each other to get 10.
Answer:
$18,424.92
Step-by-step explanation:
Assuming this is compound interest, we'll have to use this formula
A = P(1 + r)ⁿ
A = Final amount (100,000)
P = Starting amount (?)
r = Rate (.07)
n = Years (?)
65 - 40 = 25
This means you will save for 25 years, making n = 25
So far, our equation looks like this: 100,000 = P(1.07)²⁵
To isolate the variable, P, divide both sides by 1.07²⁵
100,000/1.07²⁵ = P(1.07)²⁵/1.07²⁵
P = 18,424.917752223962
You would need to set aside around $18,424.92 if you want to accumulate $100,000 in 25 years with 7% compound interest rate.
