Answer:
the answer is C: 1932 sq. cm
Step-by-step explanation:
You want to break down the sections (which is double for each)
there are 6 rectangles but you will only need to calculate for 3
1st rectangle
a = (25) (12)
a = 300 sq. cm
**then multiply by 2 = 600 sq. cm**
2nd rectangle
a = (12) (18)
a = 216 sq. cm
then 216 * 2 = 432 sq. cm
3rd rectangle
a = (25) (18)
a = 450 sq. cm
then 450 * 2 = 900 sq. cm
Total Surface Area
SA = 600 sq. cm + 432 sq. cm + 900 sq. cm
SA = 1932 sq. cm
Answer: 1.83
Step-by-step explanation:
Z = (x - mean) / standard deviation
= (97-75) / 12
= 22/12 = 11/6 = 1.83
The airplane's speed in the direction of its heading is
.. 410 mph +r*cos(θ)
where θ is the angle between the plane's heading and the direction the wind is moving toward.
That is, if the plane is moving "with the wind," its speed is (410 +r) mph.
If the plane is moving "against the wind", its speed is (410 -r) mph.
