Answer: 756
Step-by-step explanation:
The president can be elected in 28 different ways. After a student is elected president, there are 27 students left to elect a vice president from. So there are 28 x 27 = 756 different arrangements.
I agree I think the answer is 1715
Explanation:
Let M be the midpoint of AB. Then CM is the perpendicular bisector of AB. As such, center O is on CM, and OC is a radius (and CM). The tangent is perpendicular to that radius (and CM), so is parallel to AB, which is also perpendicular to CM.
If you need to go any further, you can show that triangles CMA and CMB are congruent, so (linear) angles CMA and CMB are congruent, hence both 90°.
Answer:
B
Step-by-step explanation:
For the three rectangles:
30x17=510
30x10=300
30x21=630
REMEMBER: the formula for solving triangles are Area = 1/2 base x height
For the 2 triangles:
1/2x21x8 = 84
And since there are 2 triangles that are both the exact same, you do 84x2, which equals 168
Finally, you add all the numbers together:
510+300+630+168 = 1,608
Which looks like is letter B on your paper
