Answer:
A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636
as a fraction it would be 36/99, divide both numbers by 9 to get 4/11
B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666
as a fraction that would be 33/90 , divide both by 3 to get 11/30
C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Answer:
a. =11+ 1
b. =4x+ (-7y) + (-5z) +6
c. (-3x) + (-8y) +(-4)+(-8/7z)
Step-by-step explanation:
a. 20 - 9 + 8 -7
=11+ 1 ( this is obtained by solving)
b. 4x - 7y - 5z + 6
=4x+ (-7y) + (-5z) +6
We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.
c. -3x - 8y - 4 - 8/7z
-[ 3x+8y+4+8/7z]
or
(-3x) + (-8y) +(-4) +(-8/7z)
The minus sign is taken as common leaving the expression with the plus only.
It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.
The law of cosines :
A^2 = B^2 + C^2 - 2BC cos A
2^2 = 3^2 + 4^2 - 2 . 3. 4 cos theta
= 21

Answer:
Step-by-step explanation:
8^2+5^2=c^2
64+25=c^2
89=c^2
c=
<-- this is the length of the rectangle at the bottom
2^2+()^2=c^2
4+89=c^2
c= <-- length of dotted line (diagonal)
