Answer:
reflexive property
Step-by-step explanation:
reflexive property states that a number equals itself, a = a, so since 16 = 16, or 16 equals itself, it's reflexive.
x = 4
A line with an undefined slope is a vertical line parallel to the y-axis and passing through all points with the same x-coordinate. For this reason it's equation is x = c where c is the value of the x-coordinate it passes through.
line passes through (4, 3 )
Hence equation is x = 4
Answer:
Step-by-step explanation:
3a+20=2a+26
-3a -3a
20= -1a + 26
-26 -26
-6= -1a
__ ___
-1a -1a
a=6
Answer:
21 minutes divided by 7 walls = 3 minutes per wall for 5 people.
Assuming each worker has the same exact productivity, one person would take 15 minutes to paint a single wall (3 minutes x 5 people to get the amount of time for 1 worker per wall).
15 minutes for one worker multiplied by 5 walls = 75 minutes for one worker. Divide 75 minutes by 3 people = 25 minutes to paint all 5 walls with 3 people.
Step-by-step explanation:
Triangle is equilateral with sides of 6.
Therefore all angles = 60°
Ht of 30-60-90 is 3sr3 = 5.196
Area of 30-60-90 = 1/2×b×h = 3×5.196
Area = 15.59
Pie slice from each corner = 60/360×pi×r^2, with r = 3
1/6×pi×9 = 4.71 × 3 pie slices = 14.13
So, shaded inner region = area triangle - 3 pie corners = 15.59-14.13
= 1.46
