Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A
The level of the sea's surface, used in reckoning the height of things such as hills and as a barometric standard.
If you are looking for the exact height of the sea just google it it's different all over the world.
Hope that's what you're looking for.
We know there are 8 equal slices. There are 4 parts to the pie.
8 ÷ 4 = 2
We now know each part of the pie has 2 slices
Ruben ate 3/4 of the slices so,
2 x 3 = 6
6 is your numerator (top) (standing for how much Ruben ate)
8 is your denominator (bottom) (standing for total slices)
6 slices was eaten by Ruben
If you want to check your work, divide the numerator and denominator by 2 - since there are 2 equal slices per part
6 ÷ 2 = 3
8 ÷ 2 = 4
3/4 of the pie has been eaten.
The simplified expression is the one in option B.

How to simplify the expression?</h3>
Remember that:
With these two, we can rewrite the numerator as:
Replacing that in the given expression, we have:
Now, if we multiply and divide by cos(-x), we get:
Now remember that:
With these two properties:
Then the correct option is B.

Answer:
Mean time and 13
Step-by-step explanation:
Given that
here is a five people and they spend the work in 7,10,13,20,15 hours respectively
Therefore here the concept i.e. used is average time or the meantime
And, this can be determined below:
= Sum of observations ÷ number of observations
= (7 + 10 + 13 + 20 + 15) ÷ 5
= 13
