What are 8 consecutive numbers with a sum of 108

Answers

10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 = 108

When solving a problem about consecutive numbers, an easy trick is to divide the final sum by the amount of consecutive numbers.
In this case, 108 / 8 = 13.5. This number is your center.
If you have an even amount of consecutive numbers, you will actually have two centers, with the divided answer being halfway between them.
In this case, 13 and 14.
Your consecutive numbers for this problem are 10, 11, 12, 13, 14, 15, 16, and 17. As you can see, there are an equal amount of numbers on each side of the center.

What is the percent of increase for a population that changed from 438,000 to 561,000?

Answers

To get the answer we can use proportion. We know that 438000 its 100% and we want to know how much its 561000.
438000 ------------ 100%
561000 ------------ x
Crossmultiply now
438000*x=561000*100%
438000x=56100000 /:438000 (divide both sides by 438000)
x=128%
Finally we have to subtract 128%-100%=28% to get percent of increase.
The answer is 28%.

find out how much 561000 goes over 438000, which would be 123000. then you divide to find out the ratio or percentage of the increase from 438000 would be. 123000/438000=.2808219178 so .28 so 28%.

How many ml of 1:4 solution and how many ml of sterile water are needed to prepare 600 ml of 1:20 solution ?

Answers

Answer:

Approximately 143 mL of 1:4 solution and 457 mL of water

Step-by-step explanation:

A 1:4 solution has a concentration of 1/(1+4) = 1/5 or 20%.

Similarly, a 1:20 solution has a concentration of 1/(1+20) = 1/21 or 4.76%.

If x is the mL of 20% solution and y is the mL of water, then:

x + y = 600

1/5 x = 1/21 (600)

Solve:

x = 5/21 (600)

x ≈ 143

y ≈ 457

You need approximately 143 mL of 1:4 solution and 457 mL of water.
