An unknown fraction is between 0 and 1. Which is true about the equivalent percent and decimal?
horsena [70]
Its equivalent percent is less than 100% and its equivalent decimal is less than 0.99 or less.

For example, 1/2 is a fraction between 0 and 1. Its percentage is 50%, which is less than 100%. Its decimal is 0.50, which is less than 1 or 0.99

PLEASE HELP ASAP THIS IS THE LAST QUESTION AND I AM STUCK!!

<h3>Answer:  B) 7 units</h3>

===========================================================

Explanation:

The y coordinates of the two points are the same, so we can subtract the x coordinates and apply absolute value

|R - T| = |-6 - 1| = |-7| = 7

Or we can say

|T - R| = |1 - (-6)| = |1 + 6| = |7| = 7

Either way, the two points are 7 units apart.

You could use the distance formula to get the same answer, but that's definitely overkill in my opinion. The trick mentioned above also could work if the x coordinates were the same, but the y coordinates were different. In any other case, you would have to use the distance formula.

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only
White raven [17]
To find the area of a triangle, use 1/2 x b x h.  3 x 4 = 12    1/2 of 12 = 6

There are two triangles, each of these are 6      6 x 2 = 12

The bottom shape is 3.5 x 3      3.5 x 3 = 10.5

The front shape is 3.5 x 5      3.5 x 5 = 17.5

The back shape is 3.5 x 4        3.5 x 4 = 14

Add them all together: 14 + 17.5 + 10.5 + 12 = 54

Your answer is 54!
