Answer:
32.1 pounds
Step-by-step explanation:
Given data
Percentage of body fat= 19.8%
Weight= 162pounds
Let us find 19.8% of the persons weight
=19.8/100*162
=0.198*162
=32.076
Therefore, 32.1 pounds of the weight is fat
70 laps in 40 hours
1/2+1/2=4
35+35=70
I think
2x+3=3x-4
try to isolate the x term
you must do the same thing to both sides or else it won't be equal anymore
2x+3=3x-4
add 4 to both sides
2x+3+4=3x+4-4
2x+7=3x+0
subtract 2x from both sides
2x-2x+7=3x-2x
0+7=x
7=x
the answer is x=7
Answer:
The total volume of the pieces of fruit in the can is ![640\ cm^{3}](https://tex.z-dn.net/?f=640%5C%20cm%5E%7B3%7D)
Step-by-step explanation:
step 1
Find the volume of the cylindrical can
The volume of the can is equal to
![V=BH](https://tex.z-dn.net/?f=V%3DBH)
where
B is the area of the base of the can
H is the height of the can
we have
![B=75\ cm^{2}](https://tex.z-dn.net/?f=B%3D75%5C%20cm%5E%7B2%7D)
![H=10\ cm](https://tex.z-dn.net/?f=H%3D10%5C%20cm)
substitute
![V=(75)(10)=750\ cm^{3}](https://tex.z-dn.net/?f=V%3D%2875%29%2810%29%3D750%5C%20cm%5E%7B3%7D)
step 2
Find the volume of the pieces of fruit in the can
The volume of the pieces of fruit in the can is equal to subtract the volume of syrup from the volume of the can
![750\ cm^{3}-110\ cm^{3}=640\ cm^{3}](https://tex.z-dn.net/?f=750%5C%20cm%5E%7B3%7D-110%5C%20cm%5E%7B3%7D%3D640%5C%20cm%5E%7B3%7D)
Of means multiply.
30%=0.3
30*0.3=9
