There are 600 people on a cruise ship.The over 30s and the 30 and unders are in the ratio 4:1.
30% of the over 30s are female.
Work out how many of the over 30s are male.
Submit Answer
males over 30

Answers

Step-by-step explanation:

600 people is the total number of people.

with a given ratio of 4:1 we know that this total number of people is basically split into 5 (4 + 1) equal units.

each of the 5 units is therefore

600 / 5 = 120 people.

the "over 30s" are 4 of these units = 4 × 120 = 480 people.

the "30 and under" are 1 unit = 120 people.

30% of these 480 "over 30" people are female.

that leaves under normal circumstances 100 - 30 = 70% of these 480 "over 30" people to be male.

100% = 480

1% = 100%/100 = 480/100 = 4.8

70% = 1% × 70 = 4.8×70 = 48×7 = 336 people.

there are 336 males over 30 on that ship.

in sound and harmonics, the frequency of a vibrating string varies inversely to its length. A guitar string 20 inches long vibrates at a frequency of 400 cycles per second. Find the frequency of a 35- inch string.

Answers

20 inches is 400
10 inches is 200
5 iches is 100

So 20+10+5=35
Which means 400+200+100= 700

So the frequency of a 35 inch string is 700 cycles per second

What is the domain of the relation {(2, 8), (0, 8), (–1, 5), (–1, 3), (–2, 3)}?

Answers

The domain is simply all of the x values.

We have a 2, 0, -1, -1, and -2.

Get rid of duplicates, so 2, 0, -1, and -2.

We're going to want to order those, so -2, -1, 0, and 2.

And put some fancy brackets on that. {-2, -1, 0, 2}

Domain Range
    -1 3
   0 5
   2 8
   3

The domain of the relation {(2, 8), (0, 8), (-1, 5), (-1, 3), (-2, 3)} is {-1, 0, 2, 3}.
