Answer:
Yes, No, Yes
Step-by-step explanation:
Yes for m/s which is meters per second.
No for min/ft which is reversed and should be feet per minute.
Yes for km/h which is kilometers per hour.
The correct unit for speed is distance per time.
Answer:
0.91.
Step-by-step explanation:
We use the formula:
P(a U b) = p(a) + p(b) - p (a ∩ b) where P(a U b) is p(a or b) and p (a ∩ b) is p (a and b).
So p(a or b) = 0.78 + 0.66 - 0.53
= 0.91.
<span>Suppose a Cartesian plane where the positive x-axis represents 0°. An angle measuring 92° would have a terminal side that lies in Quadrant II. This is because quadrants are counted counterclockwise from the positive x-axis. An angle of 92° would have a terminal side just past the positive y-axis, therefore being in quadrant II.</span>
<u>Solution</u><u>:</u> 9:x = x:4
⇛9/x = x/4
By doing cross multiplication, we get
⇛9(4) = x(x)
⇛36 = x²
⇛x² = 36
⇛x = √(36)
⇛x = √(6*6)
∴ x = 6 Ans.
