I am a part of a whole I am greater than 3/4 but less than 9/10. I am a decimal with 3 in the hundredths place. What number am I
Alborosie

Answer:

"You" are 0.83.

(Alternative fraction version: 83/100)

Step-by-step explanation:

First, let's turn 3/4 and 9/10 into decimals.

3/4 becomes 0.75, and 9/10 becomes 0.9.


We know that it has to be a decimal, and we also know it must be greater than 0.75 but less that 0.9.


It can't be 0.73, since that's less than 0.75. It also can't be 0.93, since that's over 0.9. That means we're left with 0.83.

Our final answer is 0.83, AKA 83/100.

Apply the Pythagorean Theorem to find the distance between points A and C.
Burka [1]

the horizontal distance ( x direction) from A to C is 7 units and

the vertical distance ( y direction) is 5 units

Applying Pythagoras' Theorem to the right triangle

AC² = 7² + 5² = 49 + 25 = 74, hence

AC = \sqrt{74} = 8.6 units ( to 1 dec. place )
