A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies: C - 262 Hz
E - 330 Hz
G - 392 Hz

Determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. (Due to rounding the ratio will be approximate.) How many E waves will fit in the length of four C waves?
a.
2
b.
3
c.
4
d.
5

the answer is a

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
