Addison is making Caramel apples. She has 2 1/2 bags of apples. One bag has 8 apples, and each apple weighs 5 ounces
andrey2020 [161]

Answer:

The expression that can be used is :

Number of bags x Number of apples in a bag x Weight of 1 apple

The total weight of apples in 2 1/2 bags of apples   = 100 ounces.

Step-by-step explanation:

The given question is INCOMPLETE.

Addison is making caramel apples. She has 2 1/2 bags of apples. One full bag has 8 apples, and each apple weighs 5 ounces. Write an expression that could be used to find the total number of ounces of apples Addison has. Then find the total number of ounces.

Now, here the weight of 1 apple  = 5 ounces

1 bag = 8 apples

⇒ Weight of 8 apples  = 8 x ( weight of 1 apple)  = 8 x (5 oz)  = 40 oz

⇒ Total weight of 1 bag of apples  = 40 oz

Now, the total bags of Apples Addison has  = 2 1/2 bag  

=  2 +  1/2 bag = 2. 5 bag

So, the weight of apples in 2.5 such bags = 2.5 x ( Weight in 1 bag)

=  2.5 ( 40 oz)  = 100 oz

Hence, the total weight of apples in 2 1/2 bag  = 100 ounces.

The expression that can be used

= Number of bags x Number of apples in a bag x Weight of 1 apple

= 2 1/2 x 8 x (5 oz)

Find the dimensions of a rectangle with perimeter 84 m whose area is as large as possible. (If both values are the same number,
dsp73

Answer:

m=21 and n=21

Step-by-step explanation:

In order to maximize the area of the rectangle, you want the two side lengths to be as equal to each other as possible.

In this case, we get that 2m+2n=84, so m+n=42. In our case, m and n can equal each other, so that gives us the maximum area of 441

Proof that this works:

If we had other dimensions, like m=20 and n=22, the area would be 440, slightly less than 442. If m=19 and n=23, the area becomes 437, which is even further off from 441.
