Answer:
1:4; C
Step-by-step explanation:
If you roll two cubes, they have 6 sides meaning 6 is the highest number. That's 2 more then 4 so I will subtract to two from each which makes it certain I will roll two dice less then 4. Removing two from each is 4 ergo the answer is 1:4
I think the answer is A. (7)(5x)(10)
Answer:
y=–8, x=–1
Step-by-step explanation:
I don't have time to explain
The answer is 55.4 L<span>
x - liters of</span>the 6.35% mixture needed
6.35% = 0.0635
11.28% = 0.1128
8% = 0.08
Liters of alcohol in 6.35% mixture is 0.0635x.
Liters of alcohol in 11.28% mixture is: 0.1128 * 27.9 L = 3.147 L
We need to get 8.00% mixture:
(0.0635x + 3.147)/(27.9 + x) = 0.08
0.0635x + 3.147 = 0.8 * (27.9 + x)
0.0635x + 3.147 = 2.232 + 0.08x
3.147 - 2.232 = 0.08x - 0.0635x
0.915 = 0.0165x
x = 0.915/0.0165
x = 55.4 L
