Answer:
6x^5 - 5x^4 + 6x^3 - x^2 + 12x = 31

Explanation:

(-5x^4+6x^3- 43) + (6x^5 -x^2+ 12x+12)= 0
-5x^4 +6x^3-43 + 6x^5 - x^2 + 12x + 12=0
6x^5 - 5x^4 + 6x^3 - x^2 + 12x - 31 = 0
6x^5 - 5x^4 + 6x^3 - x^2 + 12x = 31

The note A has a frequency of 880 hertz. The note D has a frequency of 1,175 hertz. Find the ratio of D to A to two decimal plac
Trava [24]

Step-by-step explanation:

We have,

The frequency of note A is 880 Hz and the frequency of note D is 1175 Hz. It is required to find the ratio of D to A.

It means \dfrac{f_D}{f_A}.

Using the values of frequency of D and A. So,

\dfrac{f_D}{f_A}=\dfrac{1175}{880}

In decimal form,

\dfrac{f_D}{f_A}=1.33

In integer form,

\dfrac{f_D}{f_A}=\dfrac{1175 }{880}\\\\\dfrac{f_D}{f_A}=\dfrac{235}{176}

Mrs. Téllez has a roll of wrapping paper in her gift shop. She uses 1/4 yard to wrap each gift. If there are 20 yards of wrappin
Novay_Z [31]

Answer: She would wrap 80 gifts

Step-by-step explanation: Mrs Tellez has a roll of wrapping paper that is 20 yards long. For each gift she wraps she uses up one-quarter of a yard (1/4).

If she were to wrap gifts of the same size as stated, that means every gift will require the same measurement which is 1/4 of a yard. To find out how many gifts of the same size she can wrap before she uses up the entire roll, we solve as follows;

Total gifts = Total measurement/(1/4)

Total gifts = 20/(1/4)

Total gifts = 20 x 4/1

(When dividing with a fraction, the division sign turns into multiplication and the fraction is turned upside down, that is, 1/4 becomes 4/1)

Total gifts = 80

Therefore she can wrap 80 gifts of the same size from the entire roll
