Multiplying 3 by a smaller number gives a smaller product.
1/10 is smaller than 10, so 3·(1/10) is smaller than 3·10.
80x20=1600 costumes
12x90=1080 masks
1600-1080=520
they ordered 520 more costumes than masks. hope this helps!
Answer:
5/19
Step-by-step explanation:
The first one being a man is 10/20, or 1/2, odds. The second being a woman is 10/19 odds. Multiply these together to get 10/38, which is equal to 5/19.
SA = (2 x 3 x 10) + (2 x 3 x 12) + (12 x 10 x 2)
SA = 60 + 72 + 240
SA = 372
So, the surface area of the prism is 372 in².
Add the two angles and set them equal to 180, them solve for x
