Okay, to find the ratio, add up all the numbers of DVDs.
You should end up with 36 DVDs.
The question states that you need to find the ratio between the action DVDs and the total amount of DVDs.
The amount of action DVDs is 12.
Now take 32 and 12, the ratio of the action DVDs and the total amount of DVDs to get your ratio.
The ratio is 12 out of 31, or 12:32
Using the slope concept, it is found that the thundercloud is 6.43 miles above the ground.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem, we have that:
- The vertical distance is the height h.
- The horizontal distance is of 3 miles, as the sound takes 5 seconds to travel 1 mile, and it took 15 seconds.
Hence:
tan(65º) = h/3.
h = 3 x tan(65º)
h = 6.43 miles.
The thundercloud is 6.43 miles above the ground.

Add the 5 amounts:
-10 + -23 = -33
-33 + 8 + 7 + 3 = -15 cents
now divide by the number of changes (5)
-15 / 5 = -3 cents
the mean change is -3 cents
From the given, there are 5 toppings available. If the pizza is to contain only two toppings, that is one of the five toppings and one of either tomato and cheese then, there will be 10 ways to prepare the pizza. Lastly, if we include the pizza with no toppings then, we have 11 types of pizza.
