Answer:
71
Step-by-step explanation:
in a triangle all the angles together equal 180°. So all you have to do is add 43 + 66=109 and then subtract that from 180
(D) 408.04 is the correct answer. If you divide 2,727 miles by 27 miles per gallon you will get the number of gallons: = 101. Then, multiply the number of gallons by the cost per gallon: 101(4.04) = 408.04. This gives the cost of gas for this car to travel 2,727 typical miles. Hope this helps!
Actually Welcome to the Concept of the Angles.
Applying, angle sum Property of a triangle and linear pair, we get as,
180°-107 = 73°
, now angle sum property,
=> 31+73+p = 180
=> p = 180-104
=> p = 76°
here, angle p = angle x, they are vertically opposite angles, hence,
x = 76°
hence
Answer:
(4.75, 2.25)
Step-by-step explanation:
Given the coordinate (x,y). If this coordinate is reflected over the x axis, the resulting coordinate will be (x, -y)
Note that the y coordinate was negated.
Let the original point needed be (x, y)
If the new point is located at (4.75, -2.25)
Since the y coordinate was negated, then;
-y = -2.25
y = 2.25
x = 4,75 (x coordinate remains the same)
Hence the original point is (4.75, 2.25)
Answer:
Step-by-step explanation:
Given that line passes through (0,0) and (2,1)
(Note that any two points are sufficient to determine the equation of the line)
The slope = change in y/change in x = (1-0)/(2-0) = 1/2
Hence answers are:
Variable y varies directly with x. (if x increases y also increases and vice versa)
The constant of variation = slope of line = 1/2
The constant of variation is 2 is wrong since slope = 1/2
The variable y does not vary directly with x is wrong since when x increases by 1 unit y increases by 1/2 unit for all real x.
