Solve: S = n/2 (a+b) for b

Mathematics
1 answer:
IgorC [24]4 years ago
4 0

Answer:

b = -n/(2-S) -a

Step-by-step explanation:

S = n/2 (a+b)

divide both sides by (a+b)

S/(a+b) = n/2

flip the equation on the left (it is the same equation just negative)

-(a+b)/-S = n/2

divide both sides by -S

-a-b = n/(2-S)

add a to both sides

-b = n/(2-S) +a

flip the sign (multiply/divide by -1)

b = -n/(2-S) -a

Which is greater, 4.87 x 10^9 or 9.212 x 10^8? <br> please helpp
STatiana [176]

Answer: 4.87 x 10^9  is greater than 9.212 *10^8

Step-by-step explanation:

4.87 x 10^9  is greater than 9.212 *10^8 because it has the greater exponent.

4.87 * 10^9 =  4,870,000,000

9.212 *10^8= 921,200,000

4,870,000,000 > 921,200,000

If the temperature at which a certain compound melts is a random variable with mean value 120 ???? ???? and standard deviation 2
bogdanovich [222]
Answer:
Temperature is measured in units of temperature.
In SI units,  it is K (degrees Kelvin).
In CGS units, it is °C (degrees Celsius)
In English units, it is °F (degrees Fahrenheit)

Therefore the mean and standard deviation will be measured in the selected units for temperature.

12. Write the first five terms of two different sequences that have 10 as the
kodGreya [7K]

Answer:

a)  The arithmetic sequence with common difference 2 that has 8 as the first term.

b) The arithmetic sequence of common difference -5 and first term 15.

Step-by-step explanation:

Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:

8, and (8+2) = 10 Therefore the second term is 10.

Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:

15, and  (15 - 5)  = 10. Therefore again a 10 as second term.

Nick's dad wanted to measure the length of his backyard and asked Nick to do this with his footsteps. Since it was winter, they
Lerok [7]

Answer:

2244 cm

Step-by-step explanation:

The first first thing we must do is find the LCM of the following numbers

(51; 68) = 204.

This means that the first time they coincide is at 204.

Now, since his steps always coincide after 204

In Nick's case

Nick's 204 ÷ 51 = 4th step

and in the case of the father

204 ÷ 68 of his father = 3rd step.

Which means that in the 204 cm distance, there will be a total of 6 foot steps, except in the first 204 cm when your "initial" step is counted.

Replacing these values we have that the total distance will be:

67-1 (initial step) / (6 * 204) = 2244 cm
