Answer:

5 hours

Step-by-step explanation:

because every hour she runs 4 miles so in 3 hours she will run 12 miles.

so 20 she would run 5 miles.

4 miles=1 hour

8 miles=2 hours

12 miles=3 hours

16 miles=4 hours

20 miles=5 hours.

Hope this helps have a great day:)

Answer:

Tom will take 5 hours

Step-by-step explanation:

Unit Rate

Tom runs 12 miles in 3 hours. We can calculate two different unit rates:

12 miles / 3 hours = 4 miles/hour

3 hours / 12 miles = 0.25 hours/mile

The first rate measures how many miles Tom runs per hour. The second rate measures how long it takes to Tom to run one mile.

We are asked to find the time needed for Tom to run 20 miles, thus the second rate will be useful:

0.25 hours/mile * 20 miles = 5 hours

To run 20 miles, Tom will take 5 hours

Which is the most economic way to lessen electric consumption?

AysviL [449]

Answer:

1) c. Use only appliances to do the most important task in the house.

2) b. 112kwh

3) b. 111kwh

Step-by-step explanation:

Energy can be defined as the ability (capacity) to do work and it's measured in Joules. The various forms of energy are solar energy, chemical energy, thermal energy, wind energy, nuclear energy, electrical energy, etc.

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

$Power = \frac {Energy}{time}$

Energy consumption is the total amount of power used by an electronic device per unit time and it's measured in Watt-hour or Kilowatt-hour.

Mathematically, it is given by the formula;

$Energy = power * time$

Generally, the most economic way to lessen electric consumption is by ensuring only the important electrical appliances are used at all times.

2. Given the following data;

Previous reading = 2156 KWh

Present reading = 2268 KWh

To find how many kilowatt-hour was consumed;

Energy consumption = present reading - previous reading

Energy consumption = 2268 - 2156

Energy consumption = 112 KWh

3. Given the following data;

Previous reading = 5512 KWh

Present reading = 5623 KWh

To find the electrical consumption of Falogme Family;

Electrical consumption = present reading - previous reading

Electrical consumption = 5623 - 5512

Electrical consumption = 111 KWh

Find all solutions of the equation in the interval [0, 2π). cotθ+ √3= 0

Ilia_Sergeevich [38]

Answer:

{5π/6, 11π/6}

Step-by-step explanation:

Since you have memorized the trig values of common angles, you know tan(π/6) = 1/√3, so cot(π/6) = √3.

The solution to this equation is ...

cot(θ) = -√3

so θ = -π/6 or, in the domain of interest, 11π/6. There is a corresponding quadrant II angle, 5π/6.

Consider 8x2 - 48x = -104.

ki77a [65]

Answer:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

Step-by-step explanation:

Quadratic Equation Solving

We have the equation:

$8x^2-48x=-104$

Divide by 8:

$x^2-6x=-13$

Now complete the squares so the left side is a perfect square of a binomial:

$x^2-6x+9=-13+9=-4$

Factoring the perfect square:

$(x-3)^2=-4$

Taking the square root:

$x-3=\sqrt{-4}$

The square root of a negative number is an imaginary number:

$x-3=\pm 2\mathbf{i}$

Solving for x:

$x=3\pm 2\mathbf{i}$

The solutions are:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$
