Answer:B
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
First, make an expression. If it states that 200 people and 25 tables, we can assume that its a division problem. So,
200/25=?
200/25=8
8 people can sit at a table.
Let's the name the first number x and the consecutive number x + 1. The sum of both of these numbers equals to 53.
We now have our equation:
x + x + 1 = 53
Now solve for x.
x + x + 1 = 53
2x + 1 = 53 <-- Combine like terms
2x = 52 <-- Subtract 1 from each side
x = 26
So, the first number is 26 and the second number is 27.
The number would be greater. if you think about normal multiplication, when you multiply a number by 1 the number stays the same, but when you multiple the number by less then one, i.e. a fraction you get a fraction of what you had. while a number greater then one, i.e. 2, the number increases. so 1.23 is greater then one so it would increase
Height of each floor = 5 meters
time to travel from the first floor to 68th floor = ?
Speed of elevator = 7.5m/s
While an elevator travels from 1st floor to 68th floor, we will multiply the height of floor with 67 to get the distance covered by the elevator form 1st floor to 68th floor, the height of 68th floor will not be counted in the distance because an elevator reaches the 68th floor not covered the height of that floor.
Distance = 5 x 67 = 335m
Now calculate the time by using the formula;
time = distance / speed
= 335m / 7.5m/s
= 44.667 seconds
Thus, an elevator will take 44.667 seconds to reach 68th floor.
