Try this option:
1. Odd numbers, which are multiple of 15 and less then 100, are: 15, 45 and 75.
2. the sums of digits are: for 15 is 6, for 45 is 9, for 75 is 12.
3. this number is 75.
Answer:
Probability that there will be a seat available for every passenger who shows up is 50/50 or 49/50
Step-by-step explanation:
Since it is known that 5percent of people who make reservations would not show up.
Therefore 5% of 52 sold ticket is
5/100 x 52 = 2.6
That is 2 or 3 people who make reservations would not show up.
Which means 52 - 2 or 52 - 3 people would show up
50 or 49 people would show up
Since the flight can hold just 50 people
The probability that everyone that shows up would have a seat is therefore =
50/ 50 or 49/50
Answer:
I think (A is the answer
Step-by-step explanation:
srry if this is wrong
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
• Expand (2a + b)²:
(2a + b)²
= (2a + b) · (2a + b)
Multiply out the brackets by applying the distributive property of multiplication:
= (2a + b) · 2a + (2a + b) · b
= 2a · 2a + b · 2a + 2a · b + b · b
= 2²a² + 2ab + 2ab + b²
Now, group like terms together, and you get
= 2²a² + 4ab + b²
= 4a² + 4ab + b² <——— expanded form (this is the answer).
I hope this helps. =)
