Answer:
2/3
Step-by-step explanation:
The first place finishers can be divided into two groups: those who went to Ohio State, and those who did not attend Ohio State.
2/5 of the first place finishers went to Ohio State. 1/2 of these were women, which means 1/2 were men. The fraction of first place finishers who went to Ohio State AND were men is:
1/2 (2/5) = 1/5
3/5 of the first place finishers did not attend Ohio State. 2/9 of these were women, which means 7/9 were men. The fraction of first place finishers who did not attend Ohio State AND were men is:
7/9 (3/5) = 7/15
So the fraction of first place finishers who were men is:
1/5 + 7/15
= 3/15 + 7/15
= 10/15
= 2/3
Answer:
B
Step-by-step explanation:
The 115° angle is adjacent to both unknown angles in the triangles, thus
unknown angles = 180° - 115° = 65°
The sum of the 3 angles in a triangle = 180°, thus
∠ 1 = 180° - (65 + 80)° = 180° - 145° = 35°
∠ 2 = 180° - (65 + 85)° = 180° - 150° = 30°
Answer:
14,368,252.5
Step-by-step explanation:
The full answer is 14,368,252.53. Rounding to the nearest tenth would make the final answer 14,368,252.5, because the 3 would round the number down, not up.
