Answer:
about 130 hp
Step-by-step explanation:
The displacement is smaller by a factor of 220/390, so we expect the horsepower to be smaller than 230 hp by the same factor:
(220/390)(230 hp) ≈ 129.74 hp ≈ 130 hp
Answer:
385 counters
Step-by-step explanation:
Since 1/6 of the counters are red and 1/4 of the counters are blue, there are:
1 - (1 / 6) - (1 / 4) = 7 / 12
Multiply it to find green:
660 x (7 / 12) = 385 counters
Well, you would have to mutiply the length and width and then divide that by 2 to get your area for the triangle
P(Hugh) = 1/10
P(Stu) = 1/9
P(Lou) = 1/8
Required probability = 1/10 * 1/9 * 1/8 = 1/720
