Help Fast Please!!!!!!!!! How can you tell if three positive numbers form a Pythagorean triple?

Answers

Answer/Step-by-step explanation:

Square all three numbers. If the largest number squared is equal to the sum of the squares of the other two, then the numbers form a Pythagorean triple.

or

Since a Pythagorean triple is three positive integers a, b, and c such that (a^2)+(b^2)=(c^2), first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25

either one works

Answers

Answer:

4.) y=x-16

Step-by-step explanation:

Here,

y=4,

x=20

Now,

putting the value of x and y.

or, 4=20-16

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Answers

Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches

f(4)= (3(4)+2)/5

f(4)= (12+2)/5

f(4)= (14)/5

f(4)=14/5

Step-by-step explanation:

Two observers simultaneously see an airplane overhead and between them. They measure
their angle of elevation to the airplane and obtain 48° and 73º. The airplane is 1.7 miles
directly above the point shown in the figure below. How far are the two observers from each
other? Round your answer to the nearest hundreth of a mile.

Answers

Answer:

2.05 mi

Step-by-step explanation:

I don't see a figure, so I am guessing that the plane is 1.7 miles above the ground.

Let x = distance of observer 1 from that point

     y =  distance of observer 2 from that point

Tan 48 = 1.7/x           and    tan 73 = 1.7/y

x tan 48 = 1.7                       y tan 73 = 1.7

x = 1.7/tan 48                         y = 1.7/tan 73

x + y = distance between the observers

x + y = 1.7/tan 48 + 1.7/tan 73

       = 2.05 mi

Na casa de Isabel, a leitura do hidrômetro, feita no dia 20 de março, indicava 2431 metros cúbicos. Uma nova leitura, feita um mês depois, indicou 2 590 metros cúbicos. Quantos metros cúbicos de água Isabel e seus familiares consumiram nesse período?

Answers

Answer:

159 metros cúbicos

Step-by-step explanation:

Os metros cúbicos de água que Isabel e sua família consumiram durante este período são calculados como:

Nova leitura - primeira leitura

Primeira leitura = 2.431 metros cúbicos

Nova leitura = 2590 metros cúbicos

Conseqüentemente:

2.590 metros cúbicos - 2.431 metros cúbicos

= 159 metros cúbicos
