How many pennies would be in a tower that is 10 miles<br> high?
Rufina [12.5K]
Just measure the width (or height, if you'll be stacking the pennies
a mile high) of a penny, then divide 5280 feet by whatever you find.
This is a great activity for a class, and in fact a good way to start
the project. First take one penny, and work out an answer. Then get
100 pennies, and measure them; do the same calculation to see how many
pennies it will take to make a mile. There will probably be a
difference, because you can measure 100 pennies more accurately than a
single penny. Or maybe you have a micrometer that will measure one
penny precisely. Which is better can be a good discussion starter. And
don't forget to try it in metric, too.

Just to illustrate, using a very rough estimate of a penny's width,
let's say a penny is about 3/4 inch wide. The number of pennies in a
mile will be

5280 ft 12 in 1 penny
1 mile * ------- * ----- * ------- = 5280 * 12 * 4/3 pennies
1 mi 1 ft 3/4 in

This gives about 84,480 pennies. (This method of doing calculations
with units is very helpful, and would be worth teaching.)

If we measure 100 pennies as 6 ft 1 in, we will get

5280 ft 100 pennies
1 mile * ------- * ----------- = 5280 * 100 * 12 / 73 pennies
1 mi 6 1/12 ft

This gives us 86794.5205 pennies in a mile.

What is the missing constant term in the perfect square that starts with x2 + 10x ?
kirza4 [7]

Answer:

Okay so I am assuming you mean the third part?

Step-by-step explanation:

Pretty simple. So you see that the varible x^2 does not have a number in front of it, so there is no extra dividing.

A formula for a perfect square is (x^2)+2xy+y^2

Take 10 and divide it by 2.

10/2=5

You have Y. Finding the third part is squaring Y.

5^2=25

Therefore, the third part of the perfect square is 25. If you want to find Y, look at the stuff above.
