Answer:

$52.80

Step-by-step explanation:

to find the sale price, we need to determine how much is 40% of $88. to do this we multiply 88 x 40%. we need 40% in decimal form, which is .40

88 x .4 = 35.2

now that we have 40% of 88, we subtract 35.2 from 88 in order to get the sale price.

88 - 35.2 = 52.8

the sale price is $52.8

Why does a radical function with an even index only appear on one sode of the x-axis while a radical woth an odd index appears o

Sauron [17]

The right side of the x-axis represents positive domain and the left side of the x-axis represents a negative domain.

So a radical function with an even index could have a domain of x≥0, so that's why they only appear on the right side.

Whereas a radical function with an odd index has a domain of all real numbers, so they appear on both sides.

The easiest scenario to see why this is true is to test square root and cube root.

You can't have a square root (even index) of a negative number, but you can have a cube root (odd index) of a negative number.

Example: $\sqrt{-9}$ = UNDEFINED, ರ_ರ

$\sqrt[3]{-27} = -3$ , ♥‿♥

Someone help find the value of these music notes !!!

Elodia [21]

Answer:

See below

Step-by-step explanation:

1) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

2) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

3) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with a dot)

4) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

5) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 note (eighth note with dot)

6) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

7) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

8) 2/16 + 2/16 = 4/16 = 1/4 note

9) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

10) 1/16 + 1/16 = 2/16 = 1/8 note

11) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with a dot)

12) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

13) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 note (eighth note with dot)

14) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

15) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

16) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

17) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

18) 1/16 + 1/16 = 2/16 = 1/8 note

19) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

20) 2/16 + 2/16 = 4/16 = 1/4 note

21) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

22) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

23) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

24) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

25) 1/16 + 1/16 = 2/16 = 1/8 note

26) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

27) 2/16 + 2/16 = 4/16 = 1/4 note

28) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with dot)

29) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

30) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 (eighth note with dot)

Bonus Question:

1/4 + 1/8 + 1/8 + 1/4 + 1/16 + 2/8 + 1/16 + 1/4 + 1/16 + (2/16+1/8) = 4/16 + 2/16 + 2/16 + 4/16 + 4/16 + 1/16 + 4/16 + 1/16 + 2/16 + 2/16 = 26/16 = 13/8 (whole note with dot tied with eighth note with 2 dots)
