The <u>correct answer</u> is:
0.08.
Explanation:
To calculate the BAC, we first find the amount of alcohol (in grams) of the drinks. In the US, a standard drink has 14 g of alcohol. The man has 2 beers and 1 shot; this is 3 standard drinks:
3*14 = 42
This has 42 g of alcohol.
Next we convert the weight in pounds to grams. We do this by multiplying by 454:
140*454 = 63560
Next we multiply by the gender constant. For men, this is 0.68:
63560(0.68) = 43220.8
We divide the grams of alcohol by this number:
42/43220.8 = 0.000972
Multiply this by 100:
0.000972(100) = 0.0972
This is the BAC right after drinking. To account for the time that has passed, we multiply the number of hours by 0.015:
1(0.015) = 0.015
We subtract this from our immediate BAC:
0.0972-0.015 = 0.0822 ≈ 0.08
Answer:
advantage equals 0.1, mate
1) advantage of plane: 5 divided by 25 = 0.2
2) advantage of fixed pulleys = 0
3) advantage of movable pulley = 0.5
4) and you multiply 0.2 and 0.5 = 0.1
to lift 1kg you don't need force 10N, you will just need 1N
Step-by-step explanation:
The answer would be C because it is 7, then a number minus 3 which equals 35.
