Answer:

60 milligrams

Step-by-step explanation:

just cross multiply! percentages are just fractions of 100. so you can say that $\frac{45}{x} =\frac{75}{100}$

multiple 75 by x and 45 by 100 and you get

4500=75x

divide both sides by 75 and you get 60

Rhombus ABCD with vertices A(2, 6), B(6, 7),<br> C(5, 3), and D(1, 2): 180°

Korvikt [17]

Answer:

Step-by-step explanation:

Rule for the rotation of a point 180° about the origin is,

(x, y) → (-x, -y)

Therefore, images of the points after the rotation of 180° will be,

A(2, 6) → A'(-2, -6)

B(6, 7) → B'(-6, -7)

C(5, 3) → C'(-5, -3)

D(1, 2) → D'(-1, -2)

Now we can plot these points on the graph as attached.
