Which of these statements are true? Which statements are not true?

5<8

9/2>4 1/2

4=3/2

1/3<1/2

the first statement is true Because 5 is less than 8 the second statement is not true because when you change 4 and 1/2 into an improper fraction it becomes 9/2 and 9/2 is equal to 9/2 so the second statement is not true the third statement is also not true because when you change 3/2 into a proper fraction that is mixed number it becomes 1 and 1/2 and 4 is greater than 1 and 1/2 the last statement is true you can use lcm that is by comparing them

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
