Step-by-step explanation:
First you need to calculate the entire length (in meters) of the metal used in the gate, then multiple the length by 2.5 kg per meter
Break it into parts.......
four pieces on along the outside is just the perimeter of a rectangle
P = 2( L + H) both sides and the top and bottom
the two crossing metal pieces are just the hypotenuse of a right triangle and since we have two pieces of metal
a² + b² = c² or L² + H² = Hyp² solving for the htpotenuse
Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]
so the total length of the gate metal is
P = 2( L + H) plus 2 Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]
= 2( 12 + 5) + 2 [ √(12² + 5²) ]
= 34 + 2 [ √( 144 + 25) ]
= 34 + 2 ( √169)
= 34 + 2( 13)
= 34 + 26
= 60 meters of gate metal metal weighs 2.5 kg per meter
Total weight equals 60 meters times 2.5 kg per meter
Total weight = 60 (2.5) = 150 kg

Explanation: The dimensions of Ellie's boxes in meters are: 0.45m by 0.40m by 0.35 ( to convert from centimeters to meters we just divide by 100, because 1m =100cm). therefore the volume of each box is 0.063 m3
Now the dimensions of the empty van are 3.6m by 1.6m by 2.1 m, therefore its volume is: 12.096 m3
So the amount of boxes that Ellie can put in the van is equal to the volume of the van divided by the volume of each box: 192 boxes
So 192 boxes can be put into the van.
Now Ellie can put 3 boxes in the van in 1 minute, therefore the amount of time it will take her to put 192 boxes into the van will be: 64 minutes
So it takes Ellie 64 minutes to put as many boxes into the van as she can.

If necessary, round your answer to 222 decimal places.
Answers
Answer:
1/4
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
