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 :)
The formula for area of a triangle is 1/2 x base x height.
Using the given information we can solve for the height:
494 = 1/2 x 38 x height
Divide both sides by 38:
13 = 1/2 x height
Multiply each side by 2:
26 = height.
The height is 26 cm.
Answer:
y =8.7
Step-by-step explanation:
y + 8.5 = 17.2
Subtract 8.5 from each side
y +8.5-8.5 = 17.2 -8.5
y =8.7
Answer:
8.7
Step-by-step explanation:
y + 8.5 = 17.2
combine the like terms
y = 17.2-8.5
y=8.7
verify
y + 8.5 = 17.2
8.7+8.5=17.2
17.2=17.2
