Answer: The answer is 
Step-by-step explanation: Given that the penguin nursery is open two times in a day, where the number of hours open at the noon and afternoon are respectively given by
Therefore, the total number of hours 't' penguin nursery open every day is given by
Thus, the answer is
1. These angles are complementary, which means that they add up to 90 degrees.
x + 73 = 90
x = 17 degrees
2. These angles are supplementary, which means that they add up to 180 degrees.
x + 118 = 180
x = 62 degrees
Hope this helps!! :)
N(2x+y) = x +1
Differentiate both sides, using the Chain Rule on the left side.
(1 / (2x + y)) * d(2x + y)/dx = 1
(1 / (2x + y)) * (2 + dy/dx) = 1
<span>Rearrange to isolate dy/dx.

Answer:
Step-by-step explanation:
The total number of workers is our unknown. If 40% of this unknown number are women and the number of women is 1380, then the equation looks like this:
(remember that the word "of" generally means to multiply)
(also remember that we have to use the decimal form of a percent in an equation)
.40(x) = 1380 then divide to get the number of total workers:
x = 3450
