Step-by-step explanation:

the length of the hypotenuse is 4 Km, it is probable that you are looking for the value of the cathetus a.

it is a right triangle and we use Pythagoras

a² = 4² - 2²

a² = 16 - 4

a² = 12

a = √12

a = 3.46 (round 3.5)

Find three rational numbers between 1 and 0.

Alex73 [517]

Answer:

1/2, 1/4 & 3/4

Step-by-step explanation:

mean of 0 &1 is $\frac{0+1}{2} =\frac{1}{2} \\$

mean of 0 and 1/2 is $(0+\frac{1}{2} )/2=\frac{1}{2} /2=\frac{1}{2} *\frac{1}{2} =\frac{1}{4}$

mean of 1/2 and 1 is $(\frac{1}{2} +1)/2=\frac{3}{2} /2=\frac{3}{2} *\frac{1}{2} =\frac{3}{4}$

So the three rational numbers are 1/2, 1/4 & 3/4
