Answer:
80°
Step-by-step explanation:
The reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis.
An angle of -440° lies in the fourth quadrant.
For an angle θ in the fourth quadrant, the reference angle is 360° + θ.
The reference angle is
360° - 440° = 80°

Step-by-step explanation:
Given a line: ![y=\dfrac{3}{4}x+3](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B3%7D%7B4%7Dx%2B3)
Comparing with the slope-intercept form y=mx+c
Slope, m ![=\dfrac{3}{4}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B3%7D%7B4%7D)
Definition: Two lines are perpendicular if the product of their slopes equals -1.
Therefore, the slope of a line perpendicular to the given line
![m=-\dfrac{4}{3}](https://tex.z-dn.net/?f=m%3D-%5Cdfrac%7B4%7D%7B3%7D)
Therefore, a line that is perpendicular and passes through the point (3,1) is:
![y-y_1=m(x-x_1)\\y-1=-\dfrac{4}{3}(x-3)\\y-1=-\dfrac{4}{3}x+4\\y=-\dfrac{4}{3}x+4+1\\y=-\dfrac{4}{3}x+5](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5C%5Cy-1%3D-%5Cdfrac%7B4%7D%7B3%7D%28x-3%29%5C%5Cy-1%3D-%5Cdfrac%7B4%7D%7B3%7Dx%2B4%5C%5Cy%3D-%5Cdfrac%7B4%7D%7B3%7Dx%2B4%2B1%5C%5Cy%3D-%5Cdfrac%7B4%7D%7B3%7Dx%2B5)
Comparing with the slope-intercept from: y=mx+c
The y-intercept of the perpendicular line is therefore 5.
The correct option is D.
First, find the increase in charge between the two station. That is:
$4.12-$4.00=$0.12
Then, divide the increase by the price charged by Gas Station X.
$0.12/$4.00=0.03
Lastly, since it is a decimal, transform it to percentage by multiplying 100%
0.03x100%=3%
Hope this is the brainliest answer.
Answer:
1. a square which is 6 × 6in
2. the inside of the prism or cube as it is not seen from the outside
3. the area of the square - 6 × 6 = 36in
4. 6 x 6 = 36 / one face of prism
× 5 = 180
4 × 6/2 = 12 / one face of pyramid
x 5 = 60
60 + 180 = 240
