11/4 hours 19/8 hours 2.6 hours witch is closest to 2 hours?

ExtremeBDS [4]

Answer:

$\frac{19}{8}$ hours is closest to 2 hours.

Step-by-step explanation:

We have been given three numbers and we need to decide which of the three numbers is closest to 2.

In order to decide that, we will convert each of the given numbers into decimals and then we will compare.

$\frac{11}{4} =2.750\\\frac{19}{8}=2.375\\2.6=2.600$

Upon comparing 2.750, 2.375 and 2.600 we know that 2.375 is closest to 2. Therefore, out of the given three numbers, $\frac{19}{8}$ is closest to 2.

Find the value of the variable.

Zielflug [23.3K]

Answer:

x = 8, y = $8\sqrt{2}$

Step-by-step explanation:

$a^2+b^2=c^2$

$8^2+8^2=c^2$ Both 8 and x sides are congruent so they're equal.

$64+64=c^2$ Add 64 + 64.

$c^2=128$ Square root 128

$c^2=8\sqrt{2}$

Final answers: x = 8, y = $8\sqrt{2}$
