Step-by-step explanation:
Arc PQ is 60°
Answer:
(-239.4, 657.8) km/h
Step-by-step explanation:
Measured CCW from the +x axis, the angle at which the airplane is traveling is 110°. Then the (x, y) components of the velocity vector are ...
(700 km/h)(cos(110°), sin(110°)) ≈ (-239.4, 657.8) km/h
Answer:
A: 360
Step-by-step explanation:
Split the trapezoid into 2 shapes
Then find the area of the rectangle on the left:
18 × 15 = 270 square yards
Now for the triangle, first find the base by subtracting the 2 parallel lines:
25 - 15 = 10 yards
0.5(10 × 18) = 90 square yards
Add both areas to find total area:
270 + 90 = 360 square yards
All this can be seen in the figure below:
Answer:
Number of chaperones = 9
Step-by-step explanation:
Given:
Total number of teacher = 2
Total people attend = 54
Find:
Number of chaperones
Computation:
Assume;
Number of chaperones = x
So,
x = [54-x] / 5
5x = 54 - x
6x = 54
x = 9
Number of chaperones = 9
