Answer:
- 3/4
- 4/13
- 7/26
- 2/13
- 5.52
Step-by-step explanation:
<u>(a)</u>
- Probability (A heart or a black card) = 13 + 26 / 52
- Probability (A heart or a black card) = 39/52
- Probability (A heart or a black card) = 3/4
<u>(b)</u>
- Probability (A heart or a jack) = 13 + 3 / 52
- Probability (A heart or a jack) = 16/52
- Probability (A heart or a jack) = 4/13
<u>(c)</u>
- Probability (A heart and the ace of clubs) = 13 + 1 / 52
- Probability (A heart and the ace of clubs) = 14/52
- Probability (A heart and the ace of clubs) = 7/26
<u>(d)</u>
- Probability (A 9 or a jack) = 4 + 4 / 52
- Probability (A 9 or a jack) = 8/52
- Probability (A 9 or a jack) = 2/13
<u>(e)</u>
- Probability (The 9 of hearts or a jack) = 1 + 4 / 52
- Probability (The 9 of hearts or a jack) = 5/52
We know that one yard is equivalent to 0.9144 meters.
We are given the number of yards = 5 (1/4) yards. To know the equivalent number of meters, all we have to do is cross multiplication as follows:
number of meters = (5 1/4 * 0.9144) / 1 = 4.8006 meters
Rounding the answer to the nearest tenth, we would get 4.8 meters
Answer:
从 1 到 20 有 8 个素数。它们列在下面：2、3、5、7、11、13、17 和 19。
The equation is: 1/2h - 2 = 17
The total length of Josh's hike is: 38 km
1/2h - 2 = 17
1/2h = 19
h = 38
Answer:
L1 and L2 are parallel
BAC = 58° as it is given in the question that AB bisects DAC
similarly BCE = y°
angle B = 90° ( from figure)
Y + 58° + 90° = 180 ( angle Sum property of a triangle).
Y + 148° = 180°
Y = 180 - 148
Y = 32°
