Answer:
5 and 5
Step-by-step explanation:
Pentagon has 5 rotational and reflectional symmetries. Hope this helps. :'-)
Let r represent the radius of the smaller circle and R the radius of the larger
circle.
Apply ratios: the radius of the smaller circle to the radius of the larger circle.
r: R = 3 : 7.
I complete rotation = 360 degrees.
1st:
For one complete rotation of the smaller circle, the larger circle is rotated through (3/7)*(360) = 154.3 degrees
2nd:For one complete rotation of the larger circle, the larger circle is rotated through (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios: The number of rotations = R/r = 7/3 = 2.3 rotations
Hope this helped☺☺
Answer:
Dimensions of box
Length is 12 feet
Width is 3 feet
Step-by-step explanation:
Let's assume length of sandbox is L
width of box is W
we are given
A rectangular sandbox has a width that's 1⁄4 of its length
so, we can write as

we know that
area = length*width
so, we get

now, we can plug back W

we can set Area=36

now, we can solve for L


now, we can find W


So, dimensions of box
Length is 12 feet
Width is 3 feet
