Answer:
f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)
Step-by-step explanation:
Profit is the difference between revenue (17.12c +5.40(.5c)) and cost(14.56c+1.20(0.5c)). That difference is expressed by the function shown above.
In order to find the unit rate of acres per day, or in other words, how many acres can they plant in one day, you must divide 5/8, the number of acres planted, by 4/5, the number of days it took to plant. When you divide the two fractions, first set up an expression:
5/8<span>÷4/5
Then, to make things simpler, turn the division expression into a multiplication statement so that you have 5/8*5/4. Then multiply straight across and you get your answer as 25/32. This means that the workers can plant 25/32 acres per day.</span>
Answer:
Option C.
Step-by-step explanation:
Given information: The hypotenuse of a 45°-45°-90° triangle measures 22√2 units.
Let x be the length of one leg.
From the given figure it is clear that length of both legs are same.
According to the Pythagoras theorem, in a right angled triangle
Substitute 
in the above formula.
Divide both sides by 2.
Taking square root on both sides.
The length of one leg is 22 units.
Therefore, the correct option is C.
Answer:
Question 1: $115
Question 2: 40 + 25x
Step-by-step explanation:
Question 1: 40 + 25*3 = $115
Answer:
see explanation
Step-by-step explanation:
They are collinear if the have the same slope
(2 - -1)/(5 - 1) = 3/4
(5 - 2)/(9 - 5) = 3/4
(5 - -1)/(9 - 1) = 6/8 = 3/4
