Answer:

Step-by-step explanation:
When there is a lot of repetitive calculation, I like to let a spreadsheet do it.
Of course, the quantities are ...
- bread: 12/16 loaf
- onions: 4/16 pound
- milk: 1/4 gallon
- salt: 1/16 pound
You can enter the fractions directly in the spreadsheet (=12/16, for example), and it will do the calculation. The recipe cost is the product of recipe quantity and unit cost.
The total recipe cost and per-portion calculations should be obvious: the total is the sum of ingredient costs; the per-portion cost is that total divided by 50 portions. The spreadsheet has been set to round to 2 decimal places (cents).
Answer:
21.42
Step-by-step explanation:
Imagine it as a full circle. 3 x 4 will give you the diameter of a full circle, which is 12. circumference = pi x diameter. so 12 pi (we can work that out later). now for the quater circle, divide it by 4, so 3 pi. Then you have the 2 extra edges which are both 2r, so 6 each. finally, you have 3 pi plus 12 which = 21.42
Let's try all the answers with the above equation
a) 4 as p and -4 as q
4 - 4 = 8? INCORRECT
b) 10 as p and 1 as q
10 - 1 = 8? INCORRECT
c) -4 as p and 4 as q
-4 - 4 = 8? INCORRECT
d) 11 as p and 3 as q
11 - 3 = 8? correct
To calculate time at t= 2 minutes. We substitute at t = 2.
h = 10.5 + 6.5 sin(850t)
h = 10.5 + 6.5 sin (850 * 2)
h = 10.5 - 6.4012 = 4.1 feet
Hence at time t = 2, height = 4.1 feet.
2.36 is the answer because if you subtract 24.75 from 53.07 and then divide your answer by 12 is how you get your answer
