Answer: years of equal population are 1995 and 2022.
in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.
Step-by-step explanation: Baskinville: y = x2 - 22x + 350
Cryersport: y = 55x - 950
Note that x2 is xsquare not x2
Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.
Answer:
4.47100222
Step-by-step explanation:
157/2.5=62.8
62.8/pi= 19.98986085
square root the answer above and you get 4.47100222 for the radius
The greatest possible temperature is
and least possible temperature is 
<u>Solution:</u>
Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”
Need to determine greatest possible temperature and least possible temperature.
Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees
So greatest possible temperature will be 
Least possible temperature will be 
Hence according to weather forecaster, greatest possible temperature =
and least possible temperature = 
Answer:
90 g of water should be added and he will make 900 g of solution.
Step-by-step explanation:
Let x g be the amount of salt Ilya add to 810g of water to make 10% solution. Then 810+x g is the amount of new solution. Thus,
810+x - 100%,
x - 10%.
Mathematically,

So 90 g of water should be added and he will make 810+90=900 g of solution.
Answer:
87 grade
Step-by-step explanation:
if yo add a 10% overall grade to you 79.43 you will get an 87.373
79.43 x 10% = 7.943 (points added bc of your 10%added)
79.43 + 7.943 = 87.373
round it and you'll have 87 overall grade
