Gina's mother bought 200 lollipops and 150 pencils for goody bags for Gina's birthday. What is the largest number of goody bags

SpyIntel [72]

Answer:

In total maximum 50 goodies bags can be made, such that:

Step-by-step explanation:

Here, the total number of lollipops = 200

The total number of pencils = 150

Now, let us find the Highest Common Factor (HCF) of 200 and 150,

Here, 200 = 2 x 2 x 2 x 5 x 5

and, 150 = 2 x 3 x 5 x 5

SO, HCF of 200 and 150 = 2 x 5 x 5 = 50

Hence, in total 50 goodies bags can be made, such that:

1 bag = 200 ÷ 50 = 4 lollipops

and 1 bag = 150 ÷ 50 = 3 pencils

⇒ 1 bag = 4 lollipop + 3 pencil =7 items.

Ede4ka [16]

Answer:

1, 4, 9, <u>16, 25, 36, 49, 64, 81, 100......</u>

Step-by-step explanation:

This is a list of perfect squares.

1 is the square of 1. ( 1 x 1 = 2)

4 is the square of 2. (2 x 2 = 4)

9 is the square of 3. (3 x 3 = 9)

So, the next number would be the square of 4 which is 16 ( 4 x 4)

And so on.
