a stack of cards is placed next to a ruler, and the height of stack measured to be 3/4inches. how thick is one card
4vir4ik [10]

Total thickness of the stack of cards = 3/4 inch or 0.75 inch

In a full stack of cards, there are 52 cards.

Hence, the thickness of 52 cards = 0.75 inch.

To find the thickness of one card, we divide the total thickness with the total number of cards.

Thickness of one card = \frac{0.75}{52} = 0.014423 inch

1 inch = 2.54 cm

0.014423 inch is approximately equal to 0.34 cm.

Answer = 0.34 cm

I wanted to know what 22/7 • 1/4 and then when you multiply it what will the answer be please help me gotta turn this in tomorro
MissTica

Answer:11/14

Step-by-step explanation:

Let's multiply the numerators first. 22 x 1 is 22, so your numerator is 22.

The denominator: 7 x 4= 28, your denominator is 28.

Your answer <u><em>would</em></u> be 22/28.

However, we can simplify this.

22 and 28 are both divisible by 2.

22/2=11

28/2=14

Your final answer is <u><em>11/14</em></u>
