Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
Answer:
a. 29
Step-by-step explanation:
4 thousands = 4000
7 hundreds = 700
16 tens = 160
9 ones = 9
Then you add them all together:
4000 + 700 + 160 + 9
Your answer is 4869.
For this case we have the following variables, let:
x: The greater integer
y: The minor integer
We have to:

Thus, we have a system of two equations with two unknowns. To solve, we follow the steps below:
Step 1:
We add both equations:


Thus, the smallest integer is 
Step 2:
We substitute "y" in any of the equations and clear x:

Thus, the largest integer is 
So:

Anwer:
Integer minor, 
Integer greater,
