The slant length of each cable can be calculated using Pythagoras Theorem,
L= √ (8^2+3^2)
= √ (64+9)
= √ (73)
Total length of each cable
T = L + 8/12 + 8/12
= √ (73) + 4/3
Total length of cables required
= 3T
= 3 ( √ 73 + 4/3)
=( 3 √ 73 + 4 ) feet
Answer:
4.6 hours
Step-by-step explanation:
we first need to calculate the total distance he covered and total time taken whole for the journey.
Distance= speed X time
time = Distance/speed
let the total distance be X. he covers 2/5 if the journey first.
2/5 = 0.4
Time = 0.4x/45 hours
the remaining journey is 3/5x
he covers 1/3 X 3/5= 0.2x
time taken = 0.2/90 X hours
the remaining distance = 100× 1.2 = 120km
we add 0.4x + 0.2x to get the fraction he had covered
0.6x.
the remaining distance was X - 0.6x = 0.4 X
thus 120 km represents 0.4x of the journey
we calculate now the value of X
0.4x = 120
X = 300km
Total time taken = 0.4x/45 + 0.2/90 + 1.2 hours
replace X to get time
2.7 hours + 0.7 hours + 1.2 hours
= 4.6 hours
To find the volume of a rectangular prism, you just multiply the length x width x height.
So
1 1/4 x 4 x 3 1/4 = volume (and since they are all centimeters you don't have to worry about converting units)
You can also use decimals instead. So either the above equation or 1.25 x 4 x 3.25 = volume
and if you don't know the decimal for a fraction just pop it into a calculator if you have one, so to find 1/4 as a decimal just do 1 divided by 4 in the calculator. There are ways you can do it without a calculator but it's easier if you have one.
So the volume of this cube would be
16.25
or
16 1/4
