You must earn 243 points to have earned 93% of all possible points.
We first multiply each percentage on the previous tests by 150:
0.88*150 = 132
0.94*150 = 141
0.9*150 = 135
The total number of points possible is given by adding up the possible points for the three previous tests and the 250 for the last test:
150+150+150+250 = 700
93% of the 700 points would be 0.93(700) = 651 points.
Now we have 132+141+135+x (last test) = 651
408 + x = 651
Subtract 408 from both sides:
408+x-408 = 651-408
x = 243
To figure this out you first find the difference between -18 and 60, which is 78 you then just divide, 78/4.5 which is approximately 17.55 mins or 17.6 rounded.
To construct a perpendicular bisector, we have to draw two arcs using each of the endpoints as centers
<h3>What is a perpendicular bisector?</h3>
A perpendicular bisector is said to be a line that intersects the segment of another line perpendicularly and also divides it into two equal parts.
The properties of a perpendicular bisector include:
- It divides a line segment into two equal parts
- It makes right angles with the line segment.
- Points in the perpendicular bisector are equal from the line of the segment.
Hence, all the mentioned properties are correct except that to construct it, we have to draw two arcs using each of the endpoints as centers.
