Answer:
The depth of the lake last year was 52 feet
Step-by-step explanation:
Given as :
This year depth of lake = 39 feet
Let the last year depth of lake = x feet
Now,
According to question :
The depth this year is 25% less than that of last year
I.e 39 feet = x - 25% of x
Or, 39 feet = 
or, x = 
∴ x = 52 feet
Hence The depth of the lake last year was 52 feet Answer
25% x 4 = 100%
So,
150 x 4 = 600.

1000 grams = 1 kilogram
2000 grams = 2 kilograms
4000 grams = 4 kilograms
7000 grams = 7 kilograms
8000 grams = 8 kilograms

Answer:
B. (13√2)/2
Step-by-step explanation:
Let L represent the length of one leg of the triangle. We note that the triangle is isosceles, so both legs are the same length. Then the Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs:
13² = L² + L²
13² = 2L²
13 = (√2)L
L = 13/√2 = (13√2)/2 . . . length of one leg
_____
To "rationalize the denominator", we multiply the fraction 13/√2 by (√2)/(√2). The result is (13√2)/2.
