If you mean as a fraction it's 40/100.
Answer:
y = 16.5 ft
Step-by-step explanation:
• in the right triangle BCD :
cos(∠BCD) = 8/14
________
• In the right triangle ABC :
cos(∠BCA) = 14/(8+y)
________
Since ∠BCD and ∠BCA are the same one
then
cos(∠BCD) = cos(∠BCA)
Therefore
Time is the independent variable and cost is the dependent variable because cost of renting depends on the number of hours rented.
Step-by-step explanation:
The answer for the first box is independent variable because the independent variable is a constant value and is usually of x-coordinate.
The cost is the dependent variable because the y-value depends on the change in x-value. It is given that the cost varies as the time increases. Hence, cost is a dependent variable.
Also, the costing of renting depends on the number of hours rented, since cost is a dependent variable and the the cost raises if the time rented increases.
Thus, Time is the independent variable and cost is the dependent variable because cost of renting depends on the number of hours rented.
Answer:
Jeff's Popcorn 130^3
Step-by-step explanation
(Jeff's 130^3) .
First 20.5*10^2 which is 20.5*100 which equals 2050.
Then find the volume for the other box of popcorn.
30*8^2 which is 1920.
subtract 2050 by 1920 and you get 130.
