I'll give brainliest to whoever shows their work. plz answer fast.
jana is ordering a list of numbers from least to greatest.
which statement can be used to create her list?
a) the square root of 0.8 is less than 4/5 because 0.8= 4/5 and the square root of a number less than 1 is less than the number itself.
b) the square root of 7 is greater than the square root of 7^2 because the square root of 7^2=7 and the square root of a number greater than 1 is greater than the number itself.
c) (the square root of 5)^2 is less than the square root of 7 because (the square root of 5)^2= 5 and the square root of 7 is between 6 and 8.
d) the square root of 7 is greater than 4/5 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.

Lets check the validity of each one of our statements:

Statement A is false. The square root of a number less than 1 is greater than the number itself. In fact, . Since  is greater than ,  is greater than ; therefore, statement A is false.

Statement B is false. The square root of a number greater than 1 is less than the number itself. in fact, , whereas . Since 2.64 is less than 7,  is less than ; therefore statement B is false.

Statement C is false.  is actually less than 7 divided by two, so there is no way that  is between 6 and 8. In fact . Since 5 is greater than 2.64,  is greater than ; therefore, statement C is false.

Statement D is true. . Since 2.64 is greater than 0.8,  is greater than .

We can conclude that Jana should use statement D to create her list; also the correct order from least to greatest is: , ,, , 

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
