He has worked for 5 hours. 8 and 1/3 is equal to 24/3. Multiply that by 3/5 to get 75/15 which simplifies to 5.
The polar coordinate of any point can be written as:
(r, θ) = (r, θ + 2nπ) when positive
(r, θ) = [ - r, θ + (2n + 1)π ] when negative
The polar coordinates of this given point P is: P = (r, θ) = (5, π/3).
When the value of r is positive, the polar coordinate is written as P= (5, π/3) = (5, π/3 + 2nπ)
When the value of r is negative, the polar coordinate is written as P = (5, π/3) = [ - 5, π/3 + (2n + 1)π] where n is any integer.
Therefore all polar coordinates of point P are (5, π/3 + 2nπ) and [ - 5, π/3 + (2n + 1)π ].
Answer:
16 lamps
Step-by-step explanation:
we know that
96 lamps represent the 100%
so
using proportion
Find out how many lamps represent 16 2/3%
but first convert to an improper fraction
Apply proportion
Answer:
If there is no tax involved, it is $2.08.
Step-by-step explanation:
First, you add together the costs of the pen and the hat.
Then, you subtract that from 20.
20-17.92=2.08
Answer:
This is the concept of financial mathematics;
Break even point is defined mathematically as:
Cost=Revenue
At this point the organization doesn't make any profits because the cost is equal to the revenue. Therefore , to solve our expression we proceed as follows;
The question requires us to find the number of units of products that must be sold in order to break even, to solve this we proceed as follows;
At break even;
C=R
but;
C=13x+80
R=18x
hence;
18x=13x+80
putting the like terms together we get:
18x-13x=80
5x=80
dividing both sides by 5 we get:
(5x)/5=80/5
x=16
Therefore the number of units that must be sold in order to break even is:
x=16 units
Step-by-step explanation:
Hope this helps! (:
