Answer:
Step-by-step explanation:
The most significant digits are three in 13.8. So one should round to the nearest tenth. In this case 17.3
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
Answer:
Sharika needs 2.5 days to finish the remaining work
Step-by-step explanation:
Sharika can do a work in 6 days palkey can do it in 8 days
Then the amount of work sharika can do in 1 day = 1/6
And the amount of work palkey can do in 1 day = 1/8
The amount of work both of them can do together in 1 day = 1/6 + 1/8
= 7/24
The amount of work both of them can do together in 2 day = (2× 7/24)
= 7/12
Since Palkey left the work,the amount of
work remaining for Sharika to do alone = (1 - 7/12 )
= 5/12
The number of days Sharika take to finish the remainig work. = (5/12 ÷ 1/6 )
= 5/2 days
Therefore, Sharika needs 2.5 days to finish the remaining work.
