Answer:
49.95
Step-by-step explanation:
I got this answer by rounding 9.99 to 10 and I remembered I rounded it up by 1 cent. Then I multiplied 10 by 5 which is 50. then I multiplied 1 (cent) by 5 which is 5 cents and subtracted it from 50 which is 49.95
The correct answer is 6 × (7 + 2) - 1 = 53. This is because in the Order of Operations, multiplying comes first. So to make sure you get the right answer, you have to put the 7 + 2 in parentheses to get 6 × 9 - 1 and not 6 × 7 + 1.

Answer:
D. 
Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

Answer:
Explanation:
The first figure attached is the sketch of the property mentioned on the question, where all the lengths listed are in meters.
The second figure attached identifies a right triangle whose hypotenuse, c, is the smallest length that the clothesline can measure; and the legs measure 20m, and 20m - 10m = 15m.
Now, you can use the Pythagorean theorem to find the smallest length of the clothesline:
