Answer:
V = lwh
/lw /lw
<h2><em><u>
h = V/lw</u></em></h2>
First isolate the variable by seperating lw from the side that h is on. You do this by dividing both sides by lw. This will result in h being volume over lenght and width.
Answer:
Option (c) is correct.
Step-by-step explanation:
See the attached figure.
Here, x + y = 10 cm. ............ (1)
The height h divides the whole right triangle into two different right triangles.
If we consider the height as h, then applying Pythagoras Theorem,
h² = 6² - x² {From small triangle} ........... (2)
Again, from large triangle we can write,
h² = 8² - y² .............. (3)
Now, from equation (2) and (3) we can write
6² - x² = 8² - y²
⇒ 36 - x² = 64 - (10 - x)² {From equation (1)}
⇒ 36 - x² = 64 - 100 - x² + 20x
⇒20x = 72
⇒ x = 3.6 cm.
So, from equation (1) we get, y = 10 - 3.6 = 6.4 cm.
Therefore, option (c) is correct. (Answer)

Step-by-step explanation:
Let S be the sum of the times for all winning team.
Given:
leg 1. 32 minutes 56 seconds.
leg 2. 42 minutes 28 seconds.
leg 3. 34 minutes 34 seconds.
leg 4. 39 minutes 2 seconds
We need to find the total time to run all four legs of the marathon.
Solution:
Sum of the times for all winning team.

Substitute running times for all legs.

Now, we write the minutes and seconds separately.





Therefore, Total time taken by all four legs
