Answer:
x = 30 degrees
Step-by-step explanation:
Since the lines are parallel, these angles can be seen as vertical angles, which are always the same as their opposite. Therefore,
75 = 2x + 15
To solve this, you would subtract 15 from both sides, getting you closer to finding x.
75 = 2x + 15
-15 - 15
60 = 2x
Lastly, you would divide both sides to get your value for x.
60 = 2x
/2 /2
30 = x

Answer:
14.8 pounds
Step-by-step explanation:
Here, we want to get the actual value made of fat from the body weight
What we have to do here is to multiply the percentage by the body weight
Mathematically, we have this as;
18.8% of 127 pounds
= 18.8/100 * 127 = 14.80 pounds
Answer:
4 hours
Step-by-step explanation:
5000 divided by 1135
8.2 grams = 1 mol
Na ________
22.99 grams
First multiply the value of 8.2 to 1. Then divide by the value of 22.99 to determine the number of moles of sodium present in the 8.2 gram sample.
Then use the following equation to solve for sodium atoms.
Number of moles of Na • Avogadro Number = Number of sodium atoms.
0.3566782 • (6.02 X 10^23). = 2.1472 X 10 ^ 23. Or 2.15 X 10 ^ 23.
The answer is the second option - 2.15 X 10 ^ 23.
