Answer:
Sales tax is $4.20
Step-by-step explanation:
70*6/100=4.2
Answer:66.6 but if round 67%
Step-by-step explanation:
Because 52 ÷78 =66.6
So it's 67%
Answer:
The equation of line is shown below.
Step-by-step explanation:
The equation of line is

It is the point slope form of a line, therefore the slope of the line is
and the line passing through (4,-1).
Rewrite the above equation in slope intercept form.



The point slope form of a line is

Where m is the slope and b is y-intercept.
Therefore the slope of the line is
and the y-intercept of the line is
.
Slope is defined as

Since the slope is negative, therefore the run of the line is considered on the left side. The line rise by 3 and run by 5, therefore we will add 7 in y and subtract 5 from x.
The y-intercept is
.

Therefore we have three points (4,-1), (-5,4.4) and (0,1.4). Plot the point on the coordinate plane and connect them be a straight line.
3x+75=180( cause supplementary angles)
-75 -75
3x=105
3x/3= 105/3
x=35
Answer:
121°
Step-by-step explanation:
- We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°
- We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.
Therefore; ∠ x = 1/2 mABC
- We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Thus;<em> 360° - 118° = 242°</em>
<em>Using the formula; ∠ x = 1/2 mABC</em>
<em>Then; d = 242/2</em>
= 121°
