660 feet

given distance varies directly with time (t) then

d = kt ( k is the constant of variation )

find k using the condition d = 264 when t = 0.5

k = $\frac{d}{t}$ = $\frac{264}{0.5}$ = 528

thus d = 528t

when t = 1.25

d = 528 × 1.25 = 660 feet

Find the measures of the interior angles of the triangle.

jeka94

Answer:

∠A = 30°

∠B = 60°

∠C= 90°

Step-by-step explanation:

This is a right triangle, you can see it mainly by the red square in C, and it is always used to mark 90 degrees.

Knowing that, you now know ∠C is 90°

Now, to find ∠B, you should use the following equation:

A+B+C = 180°

This means that the sum of the three angles of a triangle gives 180. ALWAYS. So to find the missing angle, ∠B, do the following:

Fill the values of the equation with the angles you now know:

30° + B + 90° = 180

Solve the equation, passing the 30° and 90° to the other side of the equal sing with Inverse Operation:

B = 180° - 30° - 90°

B = 60

Hope it helps!!

Using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equ

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
