Answer: 1/2
Step-by-step explanation:
The equation given is simplified into y= -2x-3. The slope being -2. When a line is perpendicular you find the opposite inverse. That being -1/2. You flip the top and bottem and top numbers of the fraction. Then make it (positive or negative) opposite of the original slope value. Making it now positive 1/2
Answer:
100 degrees
Step-by-step explanation:
Angle 1 + Angle 2 = 180 degrees (linear pair theorem)
Angle 2 = Angle 6 (verticle angles theorem)
Thus, we can substitute the given values of angle one and angle six into the following equation:
Angle 1 + Angle 6 = 180
4x - 20 + 5x - 25 = 180
9x - 45 = 180
9x = 225
x = 25 degrees
Angle 2 = Angle 6
5x - 25 = Angle 6, so 5x - 25 = Angle 2
5(25) - 25 = Angle 2
100 degrees = Angle 2
Answer:
18 x 9 = 162
Step-by-step explanation:
Machine can make 114 copies in 4 minutes and 45 seconds. So first convert 45 seconds into minutes. We will use ratio and proportion for that using 1 minute = 60 seconds. So let say X minutes = 45 seconds.
solve for X as shown
= X
0.75 = X
So 45 seconds =0.75 minutes
So it takes 4 minutes +0.75 minutes = 4.75 minutes for machine to make 114 copies. We have to find copies made in 1 minute. So lets say it makes C copies in 1 minute. Again we will use ratio and proportion
=
Now solve for C as shown
=
24 = C
So machine can make 24 copies in 1 minute. So thats the final answer.
