Answer:
can you translate it to English ?
Step-by-step explanation:
You would use the Pythagorem Theory which is a^2 + b^2 = c^2
the diagonal being c and it doesn't matter how you substitute tho other either a or b. the answer is 15.588 or 15.6 inches
Yes they are equivalent because their ratio is 9
81/9= 9
63/7=9
4*25=100
The glacier was 100 feet shorter than it was originally by the end of the 25 day period.
Hope this helps :)
Okay this is how I would figure this out:
I would take 9 divided by 3 and get 3, so he can tile abut 3 square ft. in 15 minutes.
Then, I would multiply 3 by 4 because there are 4 15 in an hour. I would get 12.
So it takes Jakob 1 hour to tile 12 square feet.
Your answer is: He can tile about 12 square feet per hour.
Hope this helped :)
