Answer: Choice B</h3>
Positive, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is positive
=======================================================
Explanation:
Recall we have these rules
- positive times positive = positive
- positive times negative = negative
- negative times negative = positive
Here is one example for each rule
- 8*7 = 56
- 5*(-9) = -45
- -2*(-4) = 8
So based on that, we know that (-5)(-3) is positive. The two negatives cancel each other out so to speak. The same goes for (-8)(-6). Then multiplying any two positive numbers produces another positive outcome.

ΔABC ~ ΔFED
, this because
∠A=∠D
∠B=∠E
∠C=∠F
Answer:
16.3420
Step-by-step explanation:
here is what I got
The volume of a cylinder is pir^2h. So the answer is pi*4^2 times 4. 64 pi.
What are the theorems we can use?
Probably the most relevant is the angle at a point on the circle subtended by a chord has a measure equal to half the arc indicated by the chord.
By the theorem,
angle AEB = angle ADB = (1/2) arc AC = (1/2) 110 = 55 deg
angle BAE = angle DBE = (1/2) arc DE = (1/2) 130 = 65 deg
angle BKD + angle KDB + angle DBK = 180 deg
angle BKD + angle ADB + angle DBE = 180 deg
angle BKD = 180 - 55 - 65 = 60 degrees
Answer: 60 degrees
