First convert 14 gallons to grams (52,995.76g), all chemical reactions are related to molecular weights, in this case, 112 atomic weight units for gasoline, 32 for oxygen, 44 for carbon dioxide, and 18 for every mole of octane, 8 moles of CO2 are produced. The proportion will be (52,995.76g x 8 x 44 atomic weight units) / 112 atomic weight units. This equates to 166558.103g. Next, we convert grams to pounds. 367.19776172602 pounds.
Answer:
4.5%
Step-by-step explanation:
We know she made 21/22. That means she miss 1 so subtract 21 from 22. We get 1. then divide 22 by 1. So the equation is
which is about 0.454. Then multiply by 100 to get the percent which is 4.54. Round to nearest tenth and we get 4.5%
The answer To this question is X=15/4 - y/4
Answer:
∠ QRS = 100°
Step-by-step explanation:
Since RU bisects ∠ QRS , then
∠ QRU = ∠ SRU , that is
x + 10 = 50 ( subtract 10 from both sides )
x = 40 ( multiply both sides by 2 )
x = 80
Then
∠ QRU = x + 10 = 0.5 × 80 + 10 = 40 + 10 = 50°
∠ QRS = 50° + 50° = 100°
Answer:
x = 47 degrees
Step-by-step explanation:
First, find the supplementary angle by subtracting 180 from 103, which you get 77 degrees.
Then, add 77 and 56 to get 133 degrees.
Subtract 180 from 133 and you get 47 degrees.
