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 
.
Using the values of frequency of D and A. So,
In decimal form,
In integer form,
Answer:
y-95=-83/8(x-3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(12-95)/(11-3)
m=-83/8
y-95=-83/8(x-3)
Answer:
Step-by-step explanation:
∠5 + ∠4 = 180°
4x° + 2x° = 180°
6x° = 180°
x = 30
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
Use the Pythagorean theorem.
x^2 + 5^2 = 13^2
x^2 + 25 = 169
x^2 = 144
x = 12
