Answer:
156.5
Step-by-step explanation:
Thinking process:
The area can be calculated using the formula:
We let the substitution take place.
Therefore, we let 
Thus, 
So,
Also, the interval of the integration changes to [ 37, 65]
Thus,
= 
= 156.5 units²
5 times 1/10 is 5/10 or 1/2 of a kg. This equals 0.5 kg. You can do 3 experiments (use up until 4.5 kg)
21/50 is 42 percent of the students. You will have to find 42 percent of 350 to know. 42 percent of 350 is 147.
The second answer is right
<h3>
Answer: x = 
</h3>
Step-by-step explanation:
- Subtract 6kx from 30kx to get 24kx = 8.
- divide both sides by 24kx:
= 
- That leaves us with .
