On a map 1/2 of an inch represents 4/5 of a mile. What distance on the map represents 1 mile?
valentinak56 [21]
<h2><u>Here is the reference No funny stuff XD</u></h2>

Since it is given that 4/5 mile is equal to 1/2 inch, what we will be looking for how many inches will there be for 1 mile. 5/5 mile = 1 mile. 

This is how it would look like.

1/2 inch....       x inch

-----           =      ----- 

..4/5 mile ...... 1 mile 

Next, we cross multiply:

(1/2)1 = (4/5)x

Then divide both sides by 4/5. so we get

x = 0.025 inch

and that is 1/40 inch. Therefore, 1 mile is 1/40 inch. Hope this helps.

If a sample of pure sodium has a mass of 8.2 grams and sodium has an average atomic mass of 22.99 g/mol, how many sodium atoms a
Nonamiya [84]
8.2 grams = 1 mol
Na ________
22.99 grams

First multiply the value of 8.2 to 1. Then divide by the value of 22.99 to determine the number of moles of sodium present in the 8.2 gram sample.

Then use the following equation to solve for sodium atoms.

Number of moles of Na • Avogadro Number = Number of sodium atoms.

0.3566782 • (6.02 X 10^23). = 2.1472 X 10 ^ 23. Or 2.15 X 10 ^ 23.

The answer is the second option - 2.15 X 10 ^ 23.

How do i measure the diameter of a circle?
trapecia [35]

Answer:

Step-by-step explanation:

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

hope that helps!
