1/4 foot every 3/4 hour how many feet in one hour
RUDIKE [14]

For this case we propose a rule of three:

\frac {1} {4} foot -------------> \frac {3} {4} hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}

So, we have\frac {1} {3} foot every hour.

Answer:

\frac {1} {3}foot every hour

Draw a line graph that represents the relationship between mass and kinetic energy in Experiment 2. Make sure to give the graph
Leya [2.2K]

The linear function that maps the relation between kinetic energy and mass is given at the end of the question.

<h3>What is the kinetic energy of an object?</h3>

The kinetic energy of an object is given by the following formula:

E = 0.5mv².

In which:

  • m is the mass of the object.
  • v is the velocity of the object.

In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:

E = 0.5m(2.5)² = 3.125m.

Hence the graph is plotted at the end of the answer.

What are the factors of x2 – 100?
Molodets [167]

Answer:

(x - 10)(x + 10)

Step-by-step explanation:

x² - 100 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - 100

= x² - 10²

= (x - 10)(x + 10)
