Answer: 1/12 or 0.083 the 3 is repeating
Step-by-step explanation:
Answer: angle Q = 75 degrees
--------------------------------------------
The tickmarks on segments PR and PQ indicate they are congruent, ie PR = PQ. Because of this, the base angles R and Q (opposite the segments mentioned) are congruent
Angle R = Angle Q
Since angle R is (2x+15) degrees, so is angle Q
Now use the idea that adding three angles of a triangle leads to 180 degrees
P+Q+R = 180
x+(2x+15)+(2x+15) = 180
5x+30 = 180
5x = 180-30
5x = 150
x = 150/5
x = 30
If x = 30, then angle Q is
angle Q = (2x+15) degrees
angle Q = (2*x+15) degrees
angle Q = (2*30+15) degrees
angle Q = (60+15) degrees
angle Q = 75 degrees
That would be A. because 75*74 because he had 75 students to pick the first time and 74 to pick the second student. So in short the answer is A.
ANSWER

EXPLANATION
The given expression is

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.
This means that, we need to isolate d on one side of the equation while all other terms are on the other side.
We subtract from both sides of the equation to obtain,

We now divide through by -1, to get,

Or

Answer:
216 cm²
Step-by-step explanation:
The shape has six faces of the 11 cm height triangles and 6 faces of the 7 cm height triangles.
The base for all of the triangles is 4
4(11)/2=22
4(7)/2=14
6(22+14)=216
