Simple...what fun!

To solve for this type of problem...it's real simple!

I will show you the easiest and fastest way to solve...

so..you have...

\frac{2}{5} = \frac{x}{35}

Just..CROSS MULTIPLY!!

2*35=70
and
5*x=5x

Leaving you with....

5x=70

Easy...now divide!!

\frac{5x}{5} = \frac{70}{5}

x=14

To check your work...plug it in....

\frac{2}{5} = \frac{14}{35}

simplify...

14/7=2

and

35/7=5

Thus, your answer.

An element has 2 isotopes: 6X at 7.59% and 7X at 92.41%.<br> What is the average atomic mass?
crimeas [40]

The average atomic mass is 6.92X

How do we compute the average atomic mass?

In a bid to  calculate the average atomic mass, we  multiply the fraction of each isotope by the mass number , then add them together.

This is more like weighted average, as shown below:

average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)

average atomic mass=(6X*7.59%)+(7X*92.41%)

average atomic mass= 6.92X

A 6-yard piece of ribbon costs $36.72. What is the price per foot?
djyliett [7]

Answer:

$2.04

Step-by-step explanation:

Note that: 1 yard = 3 feet.

First, change the amount of yard (6) to feet:

6 x 3 = 18

6 yard = 18 feet.

Note: 18 feet = $36.72

Find the cost per foot (1 feet). Note the equal sign, what you do to one side, you do to the other. Divide 18 from both sides.

(18 ft)/18 = ($36.72)/18

1 ft = 36.72/18

1 ft = 2.04/1

1 ft = $2.04
