Answer: D. 
Step-by-step explanation:
1. You have the following expression given in the problem above:
÷5
2. By definition, two expression are equivalent when they are the same even though they they are written in a different form.
3. Keeping this on mind, you can rewrite the division of those two numbers as a fraction, as you can see below:

3. Then,
is the equivalent expression to 4h ÷ 5.

Hello!</h2>
The answer is: 33.33%
<h2>Why?</h2>
Since we have the average number of accidents that occurs in 1 month, and it's equal to 3, we can calculate the probability of 1 accident occurs by dividing it into the average number of accidents, using the following formula:

Where,
Favorable outcomes are the occurrence of the event, for this case, it's equal to 1.
Outcomes are the possible occurrence of the event, for this case, it's equal to 3.
So, by substituting we have:


So, the probability will be equal to 33.33%
Have a nice day!
M is equal to the value m
The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
<h3>
Answer:</h3>
8/13
<h3>
Step-by-step explanation:</h3>
Given in the question
Ratio of sandwiches white bread to brown bread is 10 : 3
white bread fraction = 10/13
brown bread fraction = 3/13
It is also provided that
2/3 white are vegetarian
1/2 brown are vegetarian
So
for white bread vegetables sandwich we will find 2/3 of 10
20/3/13
for brown bread vegetable sandwich we will find 1/2 of 3
3/2/13
adding both
20/3/13 + 3/2/13
8/13 (approximate)
