You have to divide the numerator by the denominator and exclude the possibility that the initial denominator be zero.
When you divide [2x - 3x^2] / 5x^3 you simply must simplify an x and obtain:
[2 - 3x] / 5x^2, and x ≠ 0.
So the answer is the option d. but you must use ≠ instead of =.
Probably most likely 1.25% because in the question it doesn't say there is any blue marbles.
Answer:
It will take 3.6 hours to wax a car if they work together.
Step-by-step explanation:
Calvin one hour work = 
Alvin one hour work = 
To find out how much they can do together per hour,
We have to add and
= 
= 
--------------(1)
They can do of the job per hour.
If "t" is the time taken to finish the job together, then one hour work
------------------------(2)
Now we have to find the value of "t" by setting the expression (1) and (2) equal.
It can solve by flipping the equation;
t = 3.6 hours
It will take 3.6 hours to wax a car if they work together.
Answer:
8
Step-by-step explanation:
There are 15 -9 = 6 that are peanut and not small. Adding the 2 that are peanut and small, there are a total of 8 peanut M&Ms.
Answer: 310.3° or 5.41 radians.
Step-by-step explanation:
The area of a circle of radius R is calculated as:
A = pi*R^2
Now, if we have a sector of an angle θ degrees, the area of that sector is:
A = (θ/360°)*pi*R^2
In this case, we know that:
R = 15yd
And the area of the sector is 609 yd^2
Then we can replace these two values in the equation to get:
609yd^2 =(θ/360°)*3.14*(15yd)^2
(609yd^2)*360°/(3.14*(15yd)^2) = θ = 310.3°
And we want the angle also in radians.
We know that:
3.14 rad = 180°
(3.14 rad/180°) = 1
Then:
310.3° = 310.3°*(3.14 rad/180°) = (310.3°/180°)*3.14 rad = 5.41 radians.
