On a piano, a key has a frequency, say f0. each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). given an initial key frequency, output that frequency and the next 4 higher key frequencies. ex: if the input is 440 (the a key near the middle of a piano keyboard), the output is: 440 466.1637615180899 493.8833012561241 523.2511306011974 554.3652619537443 note: use one statement to compute r = 2(1/12). then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4. note: import the math module as part of your code to you compute r = 2(1/12)

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

the answer is 5/14.

hope this .
