A rotation is a turn of a shape. A rotation is described by the centre of rotation, the angle of rotation, and the direction of the turn. The centre of rotation is the point that a shape rotates around. ... The direction of rotation can be described as clockwise (CW) or counterclockwise
(4) 64 tiles, (5) 
, (6) 
Step-by-step explanation:
Given data: Side length of square tile = 1 ft
(4) Side length of square pool = 8 ft
= 64
Hence 64 tiles needed for the border.
(5) Suppose number of square tiles be N and side of square tub is s ft.
So, N = 
So, the expression is .
(6) The equivalent expression is 
.
Answer:
x = 0.36
Step-by-step explanation:
22.5x − 4.6 = 3.5
first, add the -4.6 over
22.5x = 8.1
then, divide 8.1 by 22.5
x = 0.36
best of luck!
By their angles, as in a right triangle all the angles have the same degree.
Answer:
7.56 km²
Step-by-step explanation:
Given data:
Width of the fjord, w = 6.3 km
Retreated terminus of the glacier between may 2001 and June 2005, d = 7.5 km
thus, the length lost , y = 7.5 - 6.3 = 1.2 km
now, the area is given as:
A = Length × width
on substituting the values, we get
A = 1.2 × 6.3
or
A = 7.56 km²
Hence, the surface area lost by the glacier in the fjord is 7.56 km²
