Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are:<em> 7, 14, 21, 28, 35. </em>You can get these by multiplying 7 to any integer.
- 7x1 = 7
- 7x2 = 14
- 7x3 = 21
- 7x4 = 28
- 7x5 = 35
In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21
<em>The answer is 21.</em>
Ok so, I assume this is 6 times 501
501
x 6
-------------
3006
5 x 6 = 30
6 x 0 = 0
6 x 1 = 6
move the decimal point to the right to have 1 real number to the left of the decimal point,
since you are moving it to the right the exponent would be negative
so you get 8.43 x 10^-6
