The key term here is inverse variation - that is, two or more variables must multiply to a certain product.
So, let's multiply 12 and 8. We get 96.
The correct pair must contain factors of 96.
16 and 6 are factors of 96, so the answer is (D).

A bus went halfway from a village to a city at a certain speed. Then it stopped in traffic for an hour. In order to catch up the

k0ka [10]

We have to assume that the speed before being stuck was sufficient to get to the destination on time had there been no delay. Call that speed "s" in km/h.

Since 200 km is "halfway", the total distance must be 400 km.

time = distance / speed
total time = (time for first half) + (delay) + (time for second half)

400/s = 200/s + 1 + 200/(s+10) . . . .times are in hours, distances in km
200/s = 1 + 200/(s+10) . . . . . . . . . . subtract 200/s
200(s+10) = s(s+10) +200s . . . . . . .multiply by s(s+10)
0 = s² +10s - 2000 . . . . . . . . . . . . . .subtract the left side
(s+50)(s-40) = 0
Solutions are s = -50, s = 40

The speed of the bus before the traffic holdup was 40 km/h.

<h2>For the number 1..</h2>

<h2>angle at center = 2×angle at circumference</h2><h2>the angle at center (o) is equal to 141</h2>

therefore:

<h2>141 = 2x</h2><h2>divide both sides by 2</h2><h2>x = 70.5</h2>

option (A).

( the number 2 and 3 questions aren't correct )

If angle a and angle b are complementary angles, they they share a common side.

Snezhnost [94]

Answer:

False.

Step-by-step explanation:

A complementary angle is an angle where two seperate angles add together for a 90 degree angle. They usually share a side, but not always.
