Answer:
Step-by-step explanation:
The heat absorbed by the ice cube is calculated by the following formula:
![Q = (10\,g)\cdot[(2.090\,\frac{J}{kg\cdot ^{\textdegree}C} )\cdot (0^{\textdegree}C +12.2^{\textdegree}C)+334\,\frac{J}{g} + (4.186\,\frac{J}{kg\cdot ^{\textdegree}C})\cdot (30.2^{\textdegree}C-0^{\textdegree}C)]](https://tex.z-dn.net/?f=Q%20%3D%20%2810%5C%2Cg%29%5Ccdot%5B%282.090%5C%2C%5Cfrac%7BJ%7D%7Bkg%5Ccdot%20%5E%7B%5Ctextdegree%7DC%7D%20%29%5Ccdot%20%280%5E%7B%5Ctextdegree%7DC%20%2B12.2%5E%7B%5Ctextdegree%7DC%29%2B334%5C%2C%5Cfrac%7BJ%7D%7Bg%7D%20%2B%20%284.186%5C%2C%5Cfrac%7BJ%7D%7Bkg%5Ccdot%20%5E%7B%5Ctextdegree%7DC%7D%29%5Ccdot%20%2830.2%5E%7B%5Ctextdegree%7DC-0%5E%7B%5Ctextdegree%7DC%29%5D)
Answer:
3125
Step-by-step explanation:
The model has three options, each one of which you can either take or not take.
Let us represent taking an option with 1 and not taking an option with 0
1. 0 0 0 ( taking none of the options)
2. 0 0 1
3. 0 1 0
4. 0 1 1
5. 1 0 0
6. 1 0 1
7. 1 1 0
8. 1 1 1 ( taking all three options)
Also you have a choice of four different colors, therefore, total number of possible combinations are
8*4= 32
Hence the largest number of cars having same options and colors is
100,000/32
3125 cars
speed of plane flying east = x
speed of plane flying west = x+75
total speed = 2x+75
distance after 4 hours ( 7-3) = 8x+300
8x+300 = 5460
8x = 5160
x = 5160/8 = 645
speed of plane flying east = 645 km/h
Answer:
#6 = 1; #7 = A (5 gallons)
Step-by-step explanation:
#6 it is 1 because you are suppose to divide 10% of 50 which gave yuu $5 and then divide 5 by 20% which is 1
