Step-by-step explanation:
- 4 & 5 are roots
Therefore, (x + 4) & (x - 5) are factors.
Required quadratic equation is given as:
3/4 = 18/24
7/8 = 21/24
1/6 = 4/24
11/12 = 22/24
The salad = 18/24 + 21/24 + 4/24 = 43/24
43/24 - 22/24 = 21/24
21/24 = 7/8
There are 7/8 cups left
Answer:
- 65 couple tickets
- 50 individual tickets
Step-by-step explanation:
The two equations are for the revenue and the number of attendees.
3p +5c = 475 . . . . . . revenue from ticket sales (dollars)
p +2c = 180 . . . . . . . number of attendees (2 persons per couple)
Substituting (180-2c) for p in the first equation, we get ...
3(180 -2c) +5c = 475
540 -c = 475 . . . . . . . . . simplify
540 -475 = c = 65 . . . . . add c-475
p = 180 -2(65) = 50 . . . . find p from c
65 couple tickets and 50 individual tickets were sold.
You use pi times radius squared. Pi 15 squared=706.858 then take 706.858 and multiply it by the depth of 12. 706.858×12=8482.3 Cm squared. 8482.3 cm to liters is about 8.5 liters
