Answer:

Approximately 62 gallons of water will be used by Lee County by the year 2025.

Step-by-step explanation:

The amount, in millions gallons of water, spent by Lee County, in t years after 2019, is given by the following equation:

$P(t) = P(0)(1 + r)^{t}$

In which P(0) is the amount spent on 2019 and r is the increse rate, as a decimal.

In the year 2019, Lee County used approximately 55 million gallons of water.

This means that $P(0) = 55$

Historical trends show that each year the water demand is increasing by a rate of approximately 2.1%.

This means that $r = 0.021$

$P(t) = P(0)(1 + r)^{t}$

$P(t) = 55(1 + 0.021)^{t}$

$P(t) = 55(1.021)^{t}$

Approximately how many million gallons of water will be used by Lee County by the year 2025?

2025 is 2025 - 2019 = 6 years after 2019. So this is P(6).

$P(t) = 55(1.021)^{t}$

$P(6) = 55(1.021)^{6}$

$P(6) = 62.3$

Rounded to the nearest millions

Approximately 62 gallons of water will be used by Lee County by the year 2025.

A brick is 5/7 of a foot tall. If you need to build a brick wall that is 10 feet tall, how many bricks tall will the wall be?

svlad2 [7]

Answer:

7 1/7

Step-by-step explanation:

For the problem:

5 /7 × 10 = ?

Convert any mixed numbers to fractions:

10 = 10

Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

5 × 10

7 × 1

50 /7

50 ÷ 7 = 7R1, therefore:

50 /7 = 7 1/7

The result is:

× 10 = 7 1/7
