I think it’s $1.35 sorry if I’m not correct
Let x be the width of the train;
50.6ft =6x-5.8ft <--- solve for x
50.6+5.8=6x
56.4 ft=6x
56.4/6=x
9.4 ft = x
Therefore the width of the train is 9.4 ft
Hope I helped :)
Use the law of Cosines where
angle A = 14+22=36 degrees
side b = 6 times 7
side c = 6 times 19
So you have a triangle with 2 legs of 42 and 114 with angle A = 36 degrees between them.
The law of Cosines is then
a^2 = 42^2 + 114^2 - 2(42)(114)Cosine(36)
Solve and take the square root.
= 7012.85 taking the square root of it
= 83.74 km apart
Answer:
Exact: 9.42
Approx: 9
Step-by-step explanation:
The area of a circle is pi*radius^2 (pi=3.14 r=radius ^2= power of 2/squared)
The diameter is two times the radius. So, we need to divide the diameter by two for the first step of solving this.
6/2=3
Now, we know the radius is 3.
Let's square it:
3^2= 3*3
3*3=9
Now, the last step is to multiply it by pi (3.14)
3.14*3=9.42
There we go! The area is 9.42 feet!
