Answer:
5 ft
Step-by-step explanation:
The previous jumper jumped p
The new jumper jumped p*1.1 and that was 5.5 ft
1.1p = 5
Divide each side by 1.1
1.1p/1.1 = 5.5/1.1
p = 5
The previous jumper jumped 5 ft
Answer:
5 ft
Step-by-step explanation:
Let the height of the previous jump be represented by j. Then 1.1j = 5.5 ft.
Dividing both sides by 1.1, we get j = 5 ft. This was the height of the previous jump.
Answer:
She is 1.5 meters below the sea level
Explanation:
The sea level is indicated by the number 0
What's above the sea level is indicated by +ve numbers
What's below the sea level is indicated by -ve numbers
We know that:
originally, her depth was 1 meter below the sea level
This means that her original depth is -1
Now, she dives an extra 0.5 meters, to get her final depth, we would add -0.5 to the original -1 meters
This means that:
her depth = -1 + (-0.5) = -1.5 meters
where the negative sign indicates that she is below the sea level
Hope this helps :)
