   In an examination, 15% candidates failed in science and 20% in Mathematics. If 10% failed in both the subjects, find percenta
igor_vitrenko [27]

Answer:

75%

Step-by-step explanation:

The 10% that failed both is part of the 15% and 20% that is mentioned. Subtract 10% from each, leaving you with 5% that failed just science, 10% that failed just math, and 10% that failed both. Add them together and you get 25%. Subtract 25% from 100%, and you remain with 75%.

The number p and 2/3 are additive inverses.
vlada-n [284]

By knowing that p and 2/3 are additive inverses, we will see that p = -2/3

So two numbers A and B are additive inverses if:

A + B = 0

Here the two numbers are p and 2/3, so we have:

2/3 + p = 0

Solving this for p gives:

p = -2/3

Then the value of p is just -2/3.

Now, I can't "drag and drop" the labels in the given image, so I will post a little graph of where each point should be:

Find the equation of the line perpendicular to y = -2x + 6 that goes through (2, 10).
neonofarm [45]
If the line is perpendicular, then its slope is the reciprocal of the given line's slope. This new line's slope is 1/2. We plug it into slope-intercept form

y = 1/2x + b

Now plug in the given point of (2, 10) and solve for b. 

10 = 1/2(2) + b
10 = 1 + b
9 = b

So your equation is y = 1/2x + 9
