What is the measure, in degrees, of the acute angle formed by the hour hand and the minute hand of a 12-hour clock at 6:48

KiRa [710]

Answer:

We know that at 6:00 they are 180 degrees from each other. Every minute, the hour hand moves 1/2 of a degree, and the minute hand moves 6 degrees. So in 48 minutes, the hour hand moves 24 degrees and the minute hand moves 288 degrees. 288-180-24=84. So, 84 degrees.

Write and solve an equation based off the verbal phrase. The sum of x and 9 is divided by 2. That quantity is equal to 3x.

mariarad [96]

Start with the sum of x and 9, giving the expression
$x + 9$
This is divided by 2 so
$\frac{x + 9}{2}$
This equals 3x so the equation is
$\frac{x + 9}{2} = 3x$
This can the be solved.
Multiply both sides by 2 to get
$x + 9 = 6x$
Then take x from both sides
$9 = 5x$
Divide by 5 to get the value for x
$1.8 = x$

Is the relationship between the temperature scales proportional?Why or why not?

zhannawk [14.2K]

Answer: No, see explanation below

Step-by-step explanation:

For the relationship between the temperature scales to be proportional, the ratio (the number we get when dividing the given temperature in Celsius by the temperature in Fahrenheit) has to be constant.

$\frac{0}{32}=0\\\frac{10}{50}=0.2\\\frac{20}{68}=0.29$

In the example, I give, we can see that is not the case. It applies to any value as well, therefore the relationship between the temperature scales is NOT proportional
