Answer:

60 (C).

Step-by-step explanation:

FIrst off, the part that's most likely confusing you is the exponents and parenthesis. The exponents, if outside the parenthesis, affect everything inside the parenthesis. If the exponents are inside the parenthesis, however, they only affect the numebr they are attached to.

5+4 = 9, so 9^2 - (5 + 4^2).

4^2 = 16.

9^2 = 81.

81 - (5 + 16) = 81 - 21.

81 - 21 = 60.

Find the midpoint of A(5,3) and B(3,-5). Place your answer in (x,y) notation with no spaces.

Midpoint means 1/2 way 
separate the x's and the y's find the middle of the x length, middle of the y length 
 x: 5 - 3 = 2    1/2 of 2 = 1   from either end  (3 + 1) or (5-1) = 4 
y: 3-(-5) = 8     1/2 of 8 = 4   from either end  (3-4) or (-5 +4) = -1 

midpoint is therefore (4, -1)

Mia uses 1/5 of a bag of gravel in the morning and 11/12 of a bag in the afternoon and how much gravel does she use in one day
wariber [46]

Answer:

She used 67/60 of a bag of gravel in one day.

Step-by-step explanation:

We must get a common denominator so we can add the two fractions.

Let's use 60!

1/5 = 12/60

11/12 = 55/60

Now we can add and get 67/60!

She used 67/60 of a bag of gravel in one day.
