Let x liters of water is lost in a month.

2.5ₓ10⁻⁴ liters of water is lost in = 1 minute

∴ x liters of water will be lost in = 3×10⁵ minutes.
∴ x = 2.5×10⁻⁴ × 3×10⁵ = 75
∴ x = 7.5 × 10¹

Find the interval on the real number line for which the radicand is nonnegative (greater than or equal to zero)</span><span> so that the radical sqrt(8 x - 8) defines a real number. Leave answer in interval notation.

</span>
sqrt(8 x - 8) is definite function if <span>8 x - 8 ≥0, </span>
8 x <span><span> ≥ 8</span> and x </span>≥ 8/ 8 = 1, x <span>≥  1, so the interval solution is [1, infinity[</span>

The admission fee at an amusement park is $12, and each ride costs $3.50. The park also offers an all-day pass with unlimited ri
gavmur [86]
Solve using system of equations.
y=total money spent, x=amount of rides
y=12+3.5x
y=33
Solve! Set them equal to each other
12+3.5x=33
-12 -12
3.5x=21
x=6
After six rides the all day pass would be cheaper. ;)

In 1950, Town A had a population of 200 people and the population increased by 200 people each year. In 1950, Town B had a popul
schepotkina [342]

Answer:

Town B will eventually overtake Town A

in 1990 Town B will have a larger population

Step-by-step explanation:

To work out how big town A will be in 1990 you need to do 200 + (200x40) because you add 40 years worth of increased population onto the starting population

To work out how big town B will be in 1990 you need to use the equation 200 X 1.1^40 because to work out plus 10 percent you need to do 1.1 and do it to the power of 40 for how many years

in 1990 town a will have a population of 8200 and town B will have a population of 9051.85
