Answer:
24
Step-by-step explanation:
The equations just need to be equal so you multiply 3 by 6 to get 8 and then 4 by 6 to get 24
3 / 4 = 18 / 24

Answer:
2
Step-by-step explanation:
The red line represents the line for women, while the blue line represents the line for men.
Age 45 is the middle of 40 and 45 on the x-axis.
The average number of awakenings during the night for 45 -year-old men ≈ 5
The average number of awakenings during the night for 45 -year-old women = 3
The difference = 5 - 3 = 2 times during the night.
Answer:
2
Step-by-step explanation:
If this product was written as an equation, it would look like this:
16 - 7 * 2
PEMDAS states that multiplication comes before addition. So, the first step in the equation is to multiply 7 and 2.
7 * 2 = 14
Now, the equation looks like:
16 - 14
All we need to do now is subtract 14 from 16.
16 - 14 = 2
So, the final answer is 2.
12P4: 11•5•9=495
11P4: 11 •10•9•8=7920
The sum of the numbers expressed in scientific notations is given by: Option B: 
<h3>How does scientific notations work?</h3>
The number is written in the form
where we have 
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
The given expression is:

Evaluating the multiplication, we get:

It is because of exponent rule that
, and because of commutative property of addition.
Thus, the sum of the numbers expressed in scientific notations is given by: Option B:
