Answer:
Step-by-step explanation:
To solve each of these all you have to do is multiply 60kg which is the whole mass of a human body times the percentage so..
Oxygen = (0.65)(60) = 39kg
Carbon = (0.18)(60) = 10.8kg
Hydrogen = (0.10)(60) = 6
Nitrogen = (0.03)(60) = 1.8kg
Calcium = (0.015)(60) = 0.9kg
Phosphorus = (0.01)(60) = 0.6kg
These numbers dont exactly add up to 60 because the percentages gives dont add up to 100%, but this is how to do it.

4.5
Answer:
(first and brainliest??) 27 degrees
Step-by-step explanation:
The top triangle's missing angle is 75 degrees because 85+20=105 and 180-105=75. Knowing this, we know that the angle that's connecting the two triangles is also 75 degrees. 78+75=153 and 180-153=27
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
