Answer:
A.The prism sliced by a plane parallel to the base will take the shape of the base.
D. The prism sliced by a plane perpendicular to the base will take the shape of the side face.
Step-by-step explanation:
A slice is a section of a plane that consists of all points where the plane meets the figure.In a right rectangular prism, the opposite faces are parallel, this means that they do not meet.Any two adjacent faces in a right rectangular prism are perpendicular, to mean one plane will contain a line that is perpendicular to the other plane.If the slice is done by a plane parallel to one face of the prism, the formed slice is a rectangular face identical to the parallel face like in option A. If the slice is done by a plane perpendicular to the base, the slice formed is a rectangular region,with a height similar to that of the prism and a shape of the side face.
Cos 30 = A/H
cos 30 = √3 / 2
answer is D.√3 / 2
Answer:
The speed of the private airplane is 770 mph, the speed of the commercial airplane is 980 mph.
Step-by-step explanation:
Let x mph be the speed of private airplane. If the speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane, then the speed of commercial airplane is (x+210) mph.
It takes the commercial jet 1.1 hours for the flight, then it covered the distance of
It takes the private airplane 1.8 hours for the flight, then it covered the distance of
The distances are the same, so
The speed of the private airplane is 770 mph, the speed of the commercial airplane is 770 + 210 = 980 mph.
Answer:
No answer is applicable for this question
Step-by-step explanation:
Start off by moving the singular numbers to one side. This can be done by subtracting 5 from both sides. Then you are left with |x-1|=-3.
After reaching this point, you must know what whatever number, negative or not, within the lines will always come out to be positive. If those lines were not there, the answer would be -2. But if -2 was inserted at this point, you would find yourself with the answer of 3=-3. Hope this helps, comment a question below if you do not understand
