the diameter of a U.S penny is 3/4 inch. how many pennies would it take to make a row 42 inches long?

Answers

Answer 1

Answer:

Answer: 56

Step-by-step explanation:

We are given that ,

The diameter of each U.S. penny = $(3)/(4)$ inch.

The length of the row of pennies = 42 inches

Then , the number of pennies in that row will be :

$=\text{Length of row}/\text{Diameter of each penny}\n\n=42/(3)/(4)\n\n=42*(4)/(3)\ \ \text{[Flip divisor fraction, multiply the original number by its reciprocal.]}\n\n=56$

Hence, the required number of pennies. = 56

Answer 2

Answer: 42 divided by 3/4 equals 56 pennies

This is an unusual way of presenting a set of data.   Usually, when they ask for the mean, it's the mean of a bunch of numbers. In this problem, it's the mean of some property of a bunch of points.

Look at the points on the graph.
There are ten points:

There are 2 points where Variable A is 1.
There are 2 points where Variable A is 2.
There is 1 point where Variable A is 3.
There is 1 point where Variable A is 4.
There are no points where Variable A is 5.
There is 1 point where Variable A is 6.
There is 1 point where Variable A is 7.
There is 1 point where Variable A is 8.
There are no points where Variable A is 9.
and
There is 1 point where Variable A is 10.

So there you have the ten numbers for Variable A :

   1, 1, 2, 2, 3, 4, 6, 7, 8, 10.

To find their mean:

   Addum up:      44

Round each decimal to the nearest whole number. 12.1

Answers

The answer is 12.
This is because 12 is a whole number. 0.1 rounds to 12 because it's closer to that number.
12.5 would round to 13 and 12.4 would round to 12.
