Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees none of the other lines add up to 180 degrees and are also part of a vertical pair
Answer:
60%
Step-by-step explanation:
First subtract Maria's answer by the actual, 40-25= 15
Next you would divide 15 by the actual. 15÷25= .6
times that by 100 to get .60×100= 60%
Answer:
y= -4/3x - 1/2 is the perpendicular line to y= 3/4x -1/2
Step-by-step explanation:
The slope would be the negative reciprocal of your current slope :)
+3/4 would turn into -4/3 and you wouldnt change the y intercept
hope this helps
Answer: 3/2
Step-by-step explanation: the answer would be 3/2 as an improper fraction or 1 and 1/2 as a mixed number
Answer:
Step-by-step explanation:
pool tables are rectanglar
Perimeter = 2L + 2W = 2(L+W) ---->>> Perimeter/2 = L + W =
Perimeter/2 - W = L
Area = L×W
Two equations and two unknowns and L is substituted into the area equation
---->> Area = (Perimeter/2 - W) x W
Area = (Perimeter x W)/2 - W² solve for W
Area = 36 and Perimeter = 26
36 ft² = (26)( W)/2 ft - W² ft²
36 ft² = 13W ft - W² ft²
W² - 13W + 36 = 0 quadratic equation factor solve for W
(W - 4)(W - 9) = 0
There are two roots
W - 4 = 0 and W - 9 = 0
W = 4 and 9 W = 9 it doesn't make sense needs to be < L
Perimeter/2 - W = L
L = 26/2 - W
= 13 - 4
L = 9 ft and W = 4 ft
