First you have to find how much each stamp costs. So u take 2.20 ÷ 5 = 0.44.
Next you take 0.44 x 7 and you should get $3.08

First, divide 2.20 by 5 to find the price of a single stamp.
2.20 ÷ 5 = 0.44
One stamp cost $0.44
Now, you multiply this by 7 to find the cost of seven stamps.
0.44 × 7 = 3.08
In 2012, seven stamps cost $3.08

Is the statement (3^5)^4 equal to (3^4)^5 ? explain the reasoning, DUE TOMORROW
Shkiper50 [21]

Note that both 5 and 4 are exponents, and their product is 5*4=20, or 4*5=20. Thus,

(3^5)^4 is equal to (3^4)^5

Review:

(a to the power b)to the power c = a to the power bc.

Thus, (3 to the power 5)^4 = 3^20; the same is true if you reverse the positions of the 5 and the 4.

drek231 [11]

Answer:

3/10

Step-by-step explanation:

Let's assume;

30 ml of Orange Juice + 45 ml of Apple Juice + 25 ml of Coconut milk = 1 glass of Cocktail

30 ml : 45 ml : 25 ml = 1

30 + 45 + 25 = 100 ml = 1 glass of Cocktail

Orange juice proportion = Amount of Orange Juice in ml ÷ 1 glass of Cocktail in ml

Orange Juice proportion = 30 ml ÷ 100 ml

= 3/10
