Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
0.5t = 0.2 + 0.4t
<u>Step 2: Solve for </u><em><u>t</u></em>
- [Subtraction Property of Equality] Subtract 0.4t on both sides: 0.1t = 0.2
- [Division Property of Equality] Divide 0.1 on both sides: t = 2
Answer:
Actual length of ship is 150 meters.
Step-by-step explanation:
As model ship is built to a scale of
1 centimeter : 5 meters and
length of model ship is 30 centimeters
Actual length of ship is 30
×
5
=
150 meters.
So 4 hours
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600seconds
4 hours=3600 seconds times 4=14400seconds
so 8 out of 14400
8/14400=2/3600=1/1800
percent means parts out of100 so
x%=x/100
the reatios are equal to
1/1800=x/100
mulitply both sides by 100
100/1800=x
1/18=x
divide out
0.055555555=x
round
0.06%
