Answer:
50 employees
Step-by-step explanation:
We can set up a proportion which would be
4/x = 8/100
This shows 4 out of x people is the same as 8% of 100.
We divide 100 by 8, and then multiply by 4 to get 50.
We can check this by plugging 50 into the proportion.
4/50 = 0.08
8/100= 0.08
There are 50 total employees at the shop.
Answer:
0.531 > 0.456
0.63 > 0.47
0.267 < 0.539
0.07 < 0.7
Step-by-step explanation:
a. 0.531 _____ 0.456
compare the numbers from left to right
5 is greater than 4 so 0.531 greater than 0.456
0.531 > 0.456
b. 0.63 _____ 0.47
6 is greater than 4. 0.63 > 0.47
c. 0.267 _____ 0.539
2 is less than 5 . so 0.267 less than 0.539
0.267 < 0.539
d. 0.07 _____ 0.7
0 is less than 7
0.07 < 0.7
Answer:
The correct answer is diagonals are equal and bisect each other.
Step-by-step explanation:
A rectangle is a quadrilateral with opposites sides equal in length and all interior angles equal to 90°. Opposite sides are parallel and adjacent sides are perpendicular. Diagonals in a rectangle are equal in length and they bisect each other. If we want to draw a circumcircle, then the point of intersection of these diagonals give the circumcenter.
Answer:
(A)
Step-by-step explanation:
Point A is at (-2,4)
Rule of a 180° rotation about the origin: (x,y) --> (-x,-y)
Using the rule, (-2,4) will become (2,-4).
A' should be (2,-4) or Option A.
