Answer:
The shark are fed of fish during the night.
Step-by-step explanation:
Given:
Weight of fish fed in the morning =
Also Given:
During the afternoon feeding the weight of fish fed will be 1/15 of a ton more than the fish fed during the morning.
Weight of fish fed in the afternoon =
Total fish fed in whole day =
We need to find the Weight of fish fed in the night.
Solution:
Now we can say that;
Weight of fish fed in the night can be calculated by by subtracting Weight of fish fed in the morning and Weight of fish fed in the afternoon from Total fish fed in whole day .
framing in equation form we get;
Weight of fish fed in the night =
Now we will use LCM for making the denominator common we get;
Weight of fish fed in the night =
Now denominator are common so we will solve the numerators.
Weight of fish fed in the night =
Hence The shark are fed of fish during the night.
Answer:
x = 4
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 9²
x² + 1 = 81 ( subtract 1 from both sides )
x² = 80 ( take square root of both sides )
x = =
=
×
= 4
