First, let x or any variable represent the number of paintings Kate initially has. After selling 12 of it, her paintings now becomes only x - 12. Then, she purchased 7 more making the number of her paintings become x - 12 + 7 = x - 5. This number tantamount to 21. 

                                           x - 5 = 21      ; x = 26

Thus, Kate initially had 26 paintings.

Answer: \dfrac{15}{64}

Step-by-step explanation:

Given

Inside radius of figure r_1=\frac{14}{2}=7\ ft

Outside radius of figure r_2=\frac{16}{2}=8\ ft

Area of outside region is A_1=\pi (8^2)

Area of inside region A_2=\pi (7)^2

Area of shaded region A_1-A_2

Probability that point lies inside the shaded region is

\Rightarrow P=\dfrac{A_1-A_2}{A_1}\\\\\Rightarrow P=\dfrac{\pi (8^2-7^2)}{\pi 8^2}\\\\\Rightarrow P=\dfrac{64-49}{64}\\\\\Rightarrow P=\dfrac{15}{64}

An isosceles triangle always has three interior angles that measure 60° each.
Nataly [62]

Answer:

False

Step-by-step explanation:

The definition given is that of an equilateral triangle, NOT that of an isosceles triangle. An isosceles triangle has <em>at least</em> two angles that are equal by definiton. They need not be 60 degrees. For example, a triangle with angle measures of 140, 20, and 20 is an isosceles triangle because two of the angles are equal. Hope this helped!
