Answer:
392
Step-by-step explanation:
Triangles XQP and YRS are right triangles because triples 6, 8, 10 are Pythagorean triples.
Extend lines XQ, YR, YS and XP and mark their intersection as A and B.
Quadrilateral XAYB is a square because all right triangles PXQ, QAR, RYS and SBP are congruent (by ASA postulate) and therefore
- all angles of the quadrilateral XAYB are right angles
- all sides of XAYB are congruent and equal to 6 + 8 = 14 units.
Segment XY is the diagonal of the square XAYB, by Pythagorean theorem,
Note: The height of the room must be 3 m instead of 3 cm because 3 cm is too small and it cannot be the height of a room.
Given:
Perimeter of the floor of a room = 18 metre
Height of the room = 3 metre
To find:
The area of 4 walls of the room.
Solution:
We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.
The curved surface area of the cuboid is
Where, h is height, l is length and b is breadth.
Perimeter of the rectangular base is 2(l+b). So,
Putting the given values, we get
Therefore, the area of 4 walls of the room is 54 sq. metres.
Answer:
Percent of strike outs per-bat = 32%
Step-by-step explanation:
Given:
Number of balls strike out = 112
Total number of ball played = 350
Find:
Percent of strike outs per-bat
Computation:
Percent of strike outs per-bat = [112/350]100
Percent of strike outs per-bat = [0.32]100
Percent of strike outs per-bat = 32%
First you have to make 7 a fraction, every fraction with the denominator 1 is a whole number, so 7 should be 7/1,
7/1×2/3
=14/3
=4 2/3
answer=4 2/3
hope this helps....
