Answer:

$2.52

Step-by-step explanation:

Mass of envelope = 10 ounce

Now, it has been given that postage costs $.54 for the first ounce and $.22 for each additional ounce.

Therefore, the cost of first ounce =$ 0.54

Now, we are left with 9 more ounces. hence cost of 9 ounces should be 9×0.22 = $1.98

Therefore, total cost of mailing a 0- ounce envelope is

0.54 + 1.98

= $2.52

First = $ 54 Another postage = $ 22 So the cost is = ($ 54 x 1) + ($ 22 x 9) Cost = $ 54 + $ 198 = $ 252 #brainly.co.id/profil/FadhilPrawira-230178

Peter mixes 4 1/2 cups of orange juice, 2 1/4 of ginger ale and 6 1/3 cups of strawberry lemonade to make some punch. What is th

To add these amounts together, we must first find their least common multiple in order to get common denominators (b/c when you add fractions, the denominators must be the same).

We'll start by listing some of their multiples.
To do this, count by whatever the denominator is:
4 1/2 (denominator is 2): 2 4 6 8 10 12 14
2 1/4 (denominator is 4): 4 8 12 16
6 1/3 (denominator is 3): 3 6 9 12 15

Look and see which is the first multiple that all three denominators have. Circle them if it helps you. In this case, it's 12.

So now we have to multiply the denominators by whatever number it takes to reach 12, and multiply by the same number to the numerator:

4 1/2 (times 6 to both top and bottom) =
4 6/12

2 1/4 (times 3) = 2 3/12

6 1/3 (times 4) = 6 4/12

Add all these fractions together, and you get 12 13/12, which is equal to 13 1/12.

Thus, Peter makes a total of 13 1/2 cups.

Hope this made sense! tell me if anything is confusing/incorrect :))
