Answer:
20 fifths
Explanation:
One rope is 1 m. This can be written as 5/5 meters. One rope will be cut into fifths. Assume that the number of fifths is x, therefore:
x * 1/5 = 5/5
x = 5
This means that each rope will be cut into 5 fifth
Now, for four rope, the number of fifths can be calculated as follows:
number of fifths = 5 * 4 = 20 fifths
Hope this helps :)
Answer:
Your travel time will be 32.71 secs.
Step-by-step explanation:
Let the total distance be x feet.
Speed while walking = feet per second
Speed on the sidewalk = feet per second
Therefore, total speed while walking on moving sidewalk =
=
=
=
Hence, your travel time will be 32.71 secs.
Answer:
10.4 to nearest tenth.
Step-by-step explanation:
If we draw lines from the centre of the circle to each vertex of the hexagon we get 6 equilateral triangles of side length 2.
Altitude of each triangle = sqrt(2^2 - 1^2)
= sqrt3.
So the area of 1 triangle = 1/2 * 2 * sqrt3
= sqrt3
Therefore the area of the hexagon = 6 * sqrt3
= 6sqrt3
= 10.3923
They equal to 180 because they are supplementary angles
I think it would either be c or b
