Answer:
Point D and It is equivalent to 75%
Step-by-step explanation:
Velocity
Formula wise:
1/2 x mass x velocity^2
1. To solve this exercise, you must make a system of equations.
2. You have that f<span>our times a number minus twice another number is -8:
</span>
4x-2y=-8
3. And t<span>he sum of the two number is 19:
</span>
x+y=19
4. As you can see, you have two equations:
4x-2y=-8 (i)
x+y=19 (ii)
5. Let's clear the "x" from the equation (ii):
x=19-y
6. Now, you need to susbtitute x=19-y into the equation (i):
4x-2y=-8
4(19-y)-2y=-8
76-4y-2y=-8
76-6y=-8
-6y=-8-76
-6y=-84
y=-84/-6
y=14
7. You must susbstitute y=14 into the equation (ii) and clear "x":
x+y=19
x+14=19
x=19-14
x=5
The answer is: 5 and 14
Answer:
a) 0.2 L
b) 4800 ml
c) 2400 ml
Step-by-step explanation:
Total volume of water = 5 litres
Since 1000 milliliters make 1 L
5L = 5000 ml
a) litres of water spilt = 200/1000 = 0.2 L
b) milliliters of water remaining = 5000 - 200 = 4800 ml
c) since it was expressly stated in the question that the remaining water was divided evenly; 4800/2 = 2400 ml in each bowl
