Answer: 1/4
Step-by-step explanation:
We can actually write an equation to find what should be added to get -1.

We get this equaiton because the problem asks what should be added to -5/4 to get -1. We put x in place to see what number fits. X is being added to the -5/4.



Answer:
B :
Step-by-step explanation:
If you divide a rhombus using its diagonals, you get 4 right triangles, whose legs are both 1/2 the length of the diagonals.
This means that the legs of one of those 4 triangles have lengths of 2x/2, and 8x/2, so the legs of one of those triangles x and 4x. This makes the length of one side equal to
. Because all 4 sides are the same length, you multiply this value by 4, and get
, which is B.
Well, if they are six sided cubes, there are 36 possible variations.
In order to achieve 10, you can either have 6,4 5,5 or 4,6 which is three.
so the probability is 3/36
X + 10 = -13
-13 - 10 = x
-23 = x
CHECK
-23 + 10 = -13
-13 = -13!
Answer:
a) YES. Repeating decimal
b) YES. Repeating decimal
c) NO. Decimal neither terminates nor repeats
d) YES. Terminating decimal
Step-by-step explanation:
Any rational number can be written as a fraction, that is, a division of integers.
a) The number
has a repetitive period of 54. It can be expressed as a fraction because its decimal are repeating forever
b) The number 0.16666... (expressed as a repeating 6) can also be converted to a fraction because it's a repeating decimal
c) The number 0.5473... cannot be expressed as a fraction because the ellipsis (...) means the decimals continue with no limit and no pattern can be found (no repetitive decimal)
d) The number 0.378 can be easily expressed as a fraction because it has a finite number of decimals (no ellipsis) or a terminating decimal
