Arthur is organising his collection of DVDs. He has 112 altogether.The ratio of comedy films to
action to horror is 6 : 7 : 3
How many of each type of DVD does he have?
Comedy
Action
Horror
​

Answers

Answer:

42 Comedy, 49 Action, 21 Horror

Step-by-step explanation:

6 comedy : 7 action : 3 horror = 16 parts or if you think of it as a fraction, 16 is the denominator and the numbers for each ratios are the numerators

112 (the total)/16 = 7 movies per part

6 parts of comedy = 6 x 7 = 42

7 parts action = 7 x 7 =49

3 parts horror = 3 x 7 = 21

Another way to think of it is:

(ex. comedy)

6/16=x/112

(CROSS MULTIPLY HERE)

16x=672

x=42

An angle measures 64° more than the measure of a complementary angle. What is the measure of each angle?

Answers

Complementary angles are 90 degrees,so if the angle is 64 degrees more,you just only have to add 90+64=154.

The measure of the angle is 154 degrees

Hope i helped.

Remember:complimentary angles add up to 90 while supplementary angles add up to 180.

Final answer:

The two angles are 13 degrees and 77 degrees respectively. Since they are complementary, they add together to make a total of 90 degrees.

Explanation:

In this question, we are seeking the measure of two angles. These angles are complementary, meaning together they add up to 90 degrees. Let's denote the first angle as 'x' and the second angle (which is 64 degrees more than the first) as 'x+64'.

Since they are complementary, this indicates that:

x + (x + 64) = 90

This simplifies into:

2x + 64 = 90

We can then subtract 64 from both sides, giving:

2x = 90 - 64, so 2x = 26

Therefore, if we divide both sides by 2 to isolate 'x', we get:

x = 13

So, the first angle measures 13 degrees. The second angle, as specified in the question, is 64 more than the first angle, so it measures:

x + 64 = 13 + 64 = 77 degrees

Result:

The first angle measures 13 degrees and the second angle measures 77 degrees.
