- 514 + 13 + 47 - 16
- 501 + 47 - 16
- 454 - 16
- 470.
C. This is because if it is an equiangular triangle this means that all the angles have the same angle. You know that all the angles in a triangle add up to 180 degrees? You just divided 180 by 3 as there are three angles in a triangle. Which gives you 60 degrees.
Answer:
±3/5
Step-by-step explanation:
±sqrt(9/25)
We can separate this into
± sqrt(9) / sqrt(25)
Since these are perfect squares
±3/5
We need to find the probability of picked out each color. The are 4 red, 7 white, and 3 blue marbles. There are 14 marbles total.
So there are 4 red marbles out of the 14 marbles total. As fraction it is
which simplifies to
. To convert to a decimal, divide 2 by 7 to get about 0.2857. To convert a decimal to a percent, move the decimal point 2 spaces down to get 28.57%
There are 7 white marbles out of 14 marbles total. As fraction it is
which simplifies to
. This is 0.5 or 50%.
There are 3 blue marbles out of 14 marbles total. As fraction it is
which can't simplify. Divide 3 by 14 to get the decimal which is about 0.2143. Move the decimal 2 spaces down (basically dividing it by 100) to get 21.43%.
