1/2 = 1/a + b/c make b the subject​

Answers

Answer 1

Answer:

b = [tex]\frac{ac-2c}{2a}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]

Multiply through by 2ac to clear the fractions

ac = 2c + 2ab ( subtract 2c from both sides )

ac- 2c = 2ab ( divide both sides by 2a )

[tex]\frac{ac-2c}{2a}[/tex] = b

A fair con is tossed 80 times in an experiment. If the coin is fair, what would be a reasonable number of times tails should appear
based on your knowledge of the theoretical probability of this event?

Answers

Answer: 40 would be a reasonable number of times tails should appear if the coin is fair. Fair means 50/50 chance.

So, divide 80 by 2. 80/2 = 40.


Mrs. Kemp began the school year with 20 students in her kindergarten class. She had 23 students at the end of the year. What was the
percent of increase in the number of students from the beginning of the year to the end of the year?

Answers

First, we’re going to use this formula:

2nd number - 1st number
————————————— x 100%
1st number


If we plug in the numbers to this equation:

23-20
———- x 100%
20

And subtract 23 to 20, the answer to this equation is:

3
—- x 100% = 15%

In this case, the percent of increase is 15%.

Answers

Answer:

7 inches

Step-by-step explanation:

The perimeter of a rectangle = 2 x ( length + breadth)

26 = 2 x (6 + breadth)

Divide both sides of the equation by 2

26/2 = 6 + width

13 = 6 + width

Collect like terms

13 - 6 = width

What is the slope of points (2,-15) and (-3,10).

Answers

Answer:

m = 5

Step-by-step explanation:

I believe you are asking, "What is the slope of the line passing through the points (2, -15) and (-3, 10)?"

As we go from (-3, 10) to (2, -15), x (the horizontal leg of a right triangle) increases by 5 (this is the 'run'), and y (the vertical leg) increases by 25 (the 'rise').  Thus, the slope of this line is

m = rise / run = 25/5, or just 5.  m = 5
