Answer:
45 degrees
Step-by-step explanation:
Ok I think it is 45 degrees try that if not super sorry
527,519 = (5 x 10^6) + (2 x 10^5) +
(7 x 10^4) + (5 x 10^2) + (1 x 10^1) +
(9 x 10^0)
Answer:
1. F (the row has 1164, the four-digit number with the least value)
2.
3. K (985 is the greatest 3-digit number)
4. J (67176 is the palindrome with the greatest number of digits)
5. K (3579 is the greatest number of odd numbers in counting order)
Step-by-step explanation:
I couldn't find an answer to number 2, sorry! You should probably go over it one more time and check that all these answers are correct. You might catch something I missed :)
Hope this helps!
The 24 pack. The 6 pack would be 41 cents per unit, the 12 would be 33, but the 24 would be 22.
Answer:
- train: 40 kph
- plane: 140 kph
Step-by-step explanation:
Let t represent the speed of the train in km/h. Then 4t-20 is the speed of the plane. Travel times are the same, so we can use the formula ...
time = distance/speed
and equate the travel times.
110/t = 385/(4t-20)
Cross multiplying gives ...
110(4t -20) = 385t
440t -2200 = 385t . . . . . eliminate parentheses
55t -2200 = 0 . . . . . . . . . subtract 385t
t -40 = 0 . . . . . . . . . divide by 55
t = 40 . . . . . . . . . . . add 40; train's speed is 40 kph
4t -20 = 140 . . . . . . find plane's speed; 140 kph
The train's speed is 40 km/h; the plane's speed is 140 km/h.
_____
<em>Check</em>
Train's travel time = 110 km/(40 km/h) = 2.75 h.
Plane's travel time = 385 km/(140 km/h) = 2.75 h.
