Answer:

Can only be simplified through calculator using decimal equivalents.
Step-by-step explanation:
The perimeter of a rectangle is the formula P=2l+2w. Here
and
. So the perimeter is:

Answer:
All except the second one (angle g is not similar to angle r)
Step-by-step explanation:
Just look at the order of the letters. It it's the same, its similar.
Let x be the length of the train.
On the basis of the observer;
Speed of the train = x/6
On the basis of the bridge;
Total distance covered by any point of the train= 350+x
Speed = (350+x)/20
Equating the two expressions of speed;
x/6 = (350+x)/20
20(x) = 6(350+x)
20x = 2100+6x
(20-6)x = 2100
14x = 2100
x= 2100/14 = 150 m
Speed = x/6 = (350+x)/20 = 150/6 = 500/20 = 25 m/s.
Therefore,
Length of train = 150 m
Speed of train = 25 m/s
Answer:
first you write the formula V=l x w x h. is vole is equal to length width height then you check the height on the question and you write then you check the width then you write then you check the height and you write after add all of them together and you will find the volume
Answer:
No Solution.
Step-by-step explanation:
x+y=8
y=3-x
-------------
x+(3-x)=8
x+3-x=8
x-x+3=8
0+3=8
3=8
