We have x = (2/5)y and x + y = 35;
then, (2/5)y + y = 35;
2y + 5y = 175;
7y = 175;
y = 27;
x = 35 - 27;
x = 8;
Answer:
as two semicircles and a rectangle
Step-by-step explanation:
If you extend the radii shown, each becomes an end of the rectangle, and also a boundary for a semicircle. The result is two semicircles and a rectangle.
_____
Of course, two semicircles make a circle, so you could also decompose this to a circle and a rectangle.
Answer:
answer is 362,880
Step-by-step explanation:
9!= 9×8×7×6×5×4×3×2×1=362,880
I believe the 4th one
an=145+an-1 and a1=20
They will ring again together at 10:15am. Because the common factor for 40, 48 and 60 is 240, which means 240 minutes, that equals to 4 hours. Hence 4 hours after 6.15am is 10.15am.
Hope this helps.
