Y α 1/x
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.
The square root of 100 is 10. The drawing must be 10 cm by 10 cm.
1 cm = 2 ft, so 10 cm must equal 20 feet.
20 * 20 = 400 square feet

A is the correct answer because it is the only one that shows the angles that add up to 180 degrees on a line since a supplementary angle is on the line and will add up to 180. D would be correct if angles 6,4,and7 were placed together as those angles together wake a line but no, this means A is the correct answer
I believe the correct answer is D ; 124.63ft^3. i apologize if it’s wrong!
The number 43 has 4 tens and 3 ones.
Now we have 43 ones given, in order to regroup them, we need to group 4 rows of 10 each and 3 rows of 1 each.
By this, we will be having:
4 rows of 10 each = 4*10 = 40
3 rows of 1 each = 3*1 = 3
which is the needed 43.
