Answer:
33.33 mL of 50%
66.67 of 80%
Step-by-step explanation:
Let x = quantity of 50% methane.
Then,
0.50x + 0.80(100 - x) = 100 × 0.70
⇒ 0.50 x + 80 - 0.80 x = 70
⇒ -0.30 x = 70 - 80
⇒ -0.30 x = -10
⇒ 
⇒ x = 33.33 mL of 50%
and, 100 - 33.33 = 66.67 of 80%
ax-bx+y=z the formula that could be used to find x
Answer:
<h2>x=z−y/a−b</h2>
To find the probability of the statistic class that it could be done at the period at 50.5 and 51.25 minutes and not their usual duration of 49 and 49 minutes so to get the probability you must subtract the time and would come up with 0.75 minutes and then divide it by 10 so the probability is 0.075
Because this is an isosceles triangle, both of the bottom angles are the same. Every triangle has a total degree of angles of 180.
56 + 56 + x = 180
112 + x = 180
-112 -112
x = 68
