Answer:
3boxes
Step-by-step explanation:
1st we should know the number of cookies
7*5=35
Divide the total of cookies to cookies per box 35/12=2 11/12
2 boxes and 11 cookies remaning (they need an extra box)= 3 boxes
Answer: a) 490.91 mph
b) 540 mph
c) speed of the wind = 49.1 mph
Step-by-step explanation:
Given that flight between Joppetown and Jawsburgh took 5 hours and 30 minutes.
Time t = 5.5hours
Distance = 2700 miles
Speed = distance/ time
Speed = 2700/5.5
Speed = 490.91 mph
The return flight took 5 hours of the same distance from = 2700 miles
Speed = 2700/5 = 540 mph
speed of the wind = the difference in the two speed
speed of the wind = 450 - 490.91
speed of the wind = 49.1 mph
Speed = 540m/s
17.549 is 17.54 rounded to the nearest hundredth
Remark
As long as the representation shows the numbers come one after another, you can get x to be anything.
Givens
x Can be the second number
x - 1 Can be the first number
x + 1 Can be the third number
x + 2 Can be the fourth number
Equation
x + x + 2= 132
Solution
2x + 2 = 132
2x = 130
x = 65
So the 4 numbers are 64 65 66 67
Check
The second and fourth numbers added together = 65 + 67 = 132
Because the zero is in both equations but just not written as a zero, there is an invisible zero in 4.73.
