Answer:
Ground speed is 61.67 km /h.
Step-by-step explanation:
Ground speed of aircraft is obtained b the sum of aircraft speed minus the current speed and direction.
For this the given formula is
81-27 cos (255 - 81 )
53.704 km/h
27 sin ( 225 - 81 ) = 2.822 km /h
so ground speed =
= 61.67 km /h
Answer:
Step-by-step explanation:
9) P(A and B) = 0.3 + 0.2 = 0.5
10) P(A and B) = 0.11 + 0.33 = 0.44
Answer:
Step-by-step explanation:
Get the perimeter of the each shape and add it all up to get the total fencing material required.
2 square flower beds = 2 x 4a = 8a
1 rectangular play ground = 2l + 2w
total fencing material = 8a + 2l + 2w
Answer:
C. x + 1 < 5; x < 4
Step-by-step explanation:
Since he already got 1 C, he can only have 3 more. Since x has to be <em>less than 4</em>, that rules out B and D instantly. A is ruled out because x can't be equal to 4 since you need less than 5 C's to get into UGA.
Hope this helps. :)
