The ratio of cassette to compact disc is 10 to 3 and the number of cassettes is 10 less than 5 times the number of compact discs

OlgaM077 [116]

There are 20 cassettes.

Step-by-step explanation:

Given,

Ratio of cassette to compact disc = 10:3

Let,

the number of cassettes = 10x

Number of compact disc = 3x

According to given statement;

the number of cassettes is 10 less than 5 times the number of compact discs.

10x = 5(Number of CD) - 10

$10x=3(5x)-10 \\10x=15x-10\\10=15x-10x\\10=5x\\5x=10$

Dividing both sides by 5

$\frac{5x}{5}=\frac{10}{5}\\x=2$

Number of cassettes= 10x = 10(2) = 20

There are 20 cassettes.

How can i find the missing angle of this shape?

Nostrana [21]

The missing angle is 130 degrees.

The sum of all the angles of a hexagon equal 720 degrees. So, you'd add all the known angles together (this gives you 590), then subtract that from 720. Thus getting 130 degrees as a final answer.

I hope this helps!

A Honda Element with a dealer invoice price of $19,700 was retail priced at $23,000 how much is the approximate percent markup b

-BARSIC- [3]

So the mark up is 23,000-19,700 = 3,300

To figure of what the percent of markup is based on the SELLING price:

3,300/23,000 = x/100; now cross multiply and you have:
23,000x = 3,300(100)
23,000x = 330,000; isolate x by dividing both sides by 23,000, and you get x= 14.35

To check your work multiply 23,000 x 0.1435 = 3000.05, which was the approximate amount of markup
