Nimfa-mama [501]

Answer:

In year 2030 the population is predicted to be 71.75 million

Step-by-step explanation:

* Lets explain how to solve the problem

- Using data from 2010 and projected to 2020, the population of

the United Kingdom (y, in millions) can be approximated by the

equation 10.0 y − 4.55 x = 581

- x is the number of years after 2000

- We need to know in what year the population is predicted to be

71.75 million

* Lets substitute the value of y in the equation by 71,75

∵ The equation of the population is 10.0 y - 4.55 x = 581

∵ y = 71.75

∴ 10.0(71.75) - 4.55 x = 581

∴ 717.5 - 4.55 x = 581

- Subtract 717.5 from both sides

∴ - 4.55 x = - 136.5

- Divide both sides by - 4.55

∴ x = 30

∵ x represents the number of years after 2000

∵ 2000 + 30 = 2030

∴ In year 2030 the population is predicted to be 71.75 million

Answer:

a y = 2

b.y = 14

c. y =56

Step-by-step explanation:

a .6 (1)- 4=2

y=2

b. 6 (3)- 4

=18-4

y=14

c. 6 (10) - 4

= 60 - 4 =56

What shows the volume

Svetllana [295]

Answer:

654 1/2 cm³

Step-by-step explanation:

First the volume of the cylinder, the formula for that is πr²h

Radius is half of diameter so 7/2=3.5

3.5^2=12.25

12.25x22/7=38.5

38.5x15=577.5

Now the cone, the formula for this is πr²h/3

It has the same radius as the cylinder so 3.5^2=12.25

12.25x22/7=38.5

38.5x6=231

231/3=77

Now we add them together to find total volume.

577.5+77=654.5
