Answer:

Both Law of Sines and Cosines can be used to determine the angle Q.

Step-by-step explanation:.

Since from Law of Sines with one angle and three sides we can find other angles using the ratio obtained with the given angle and side length opposite side if angle P is not given we couldn't use this.

Law of Cosines can be used to find any angle of triangle with all three side lengths given and angle P is also not required to find angle Q.

Alison has three times as many dimes as quarters in her purse. She has $9.35 altogether. How many coins of each type does she ha
azamat
<h3>Answers:  17 quarters and 51 dimes</h3>

========================================================

Work Shown:

x = number of quarters

3x = number of dimes

0.25x = value of just the quarters, in dollars

0.10(3x) = 0.30x = value of just the dimes, in dollars

0.25x+0.30x = 0.55x = total value in dollars

0.55x = 9.35

x = (9.35)/(0.55)

x = 17

Alison has <u>17 quarters</u> and 3x = 3*17 = <u>51 dimes</u>

17 quarters = 17*0.25 = $4.25

51 dimes = 51*0.10 = $5.10

17 quarters + 51 dimes = $4.25 + $5.10 = $9.35

The answers are confirmed.

Amarathon is about 26 miles long. Which of these shows how to convert 26 miles to feet?
Vesna [10]

Answer: the third one down

26 miles times 5,280 feet

Step-by-step explanation:

Look at the units. Miles over miles will cancel, leaving feet... 1 mile is 5,280 feet, because a mile is bigger than a foot, and there are 5,280 feet per 1 mile.
