Answer:
The length is 7.3m
Step-by-step explanation:
The end of the ladder touches the top of the tree when kept at 2.8m away from the tree.
The Tree is 4.5m tall
The length of the ladder will be: 2.8+4.5 = 7.3
3 x 10 = 5 x 621 + 11 = 9 + 2336 div 9 = 12 div 330 - 5 = 40 - 15
2 x 8 = 4 x 423 + 20= 2 + 4190 - 80 = 20 - 10
To get the volume of water in gallons we proceed as follows:
volume=length*width*height
the dimension of the pool is:
50m by 25m by 1.5 m
thus the volume will be:
50×25×1.5
=1,875 m^3
but 1 m^3= 1000 liters
therefore:
1,875 m^3=(1875x1000)=1,875,000 liters
converting the above into gallons we get:
1 gallon= 3.786 L
therefore:
1,875,000 L=1,875,000/3.786 gallons
=495,245.6418 gallons
8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
