What is the law of sines ?
he Law of Sines (or Sine Rule) is very useful for solving triangles.
According to the law ,
When we divide side a by the sine of angle A
it is equal to side b divided by the sine of angle B
and also equal to side c divided by the sine of angle C
[tex]\rm \dfrac{a}{sinA} = \dfrac{b}{sinB} = \dfrac{c}{sinC}[/tex]
It is given that in Δ PQR
r = 4.9 cm
angle R = 21
angle P =104
Length of p needs to be found
Therefore by using above equation
[tex]\rm \dfrac{r}{sinR} = \dfrac{p}{sinP}[/tex]
[tex]\rm \dfrac{4.9}{sin21^{0}} = \dfrac{p}{sin104^{0}}[/tex]
p= 13.3 cm
Therefore the length of p, to the nearest 10th of a centimeter is 13.3 cm .

Answer: yes y=12 is a solution to y over -6
Step-by-step explanation: you simply have to put 12 in for y. 12 divided by -6 = -2.
[tex] \frac{12}{ - 6} = - 2 [/tex]
[tex] - \frac{2}{1} = - 2[/tex]
Therefore, y = 12 is the correct solution.
We get -2/1 from 12/-6 by diving the top and bottom by 6.

John needs a computer for his summer class. The computer costs 385 but since he is still in school, he gets a 30% discount. What is the total amount he will spend on his computer?
Answer:
269.50, you could search it up
The total amount that he will spend on his computer will be $269.5.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
For his summer course, John has to have a computer. Since he is still enrolled in school, he receives a 30% discount off the computer's $385 price.
The amount of discount is calculated as,
⇒ 0.30 x 385
⇒ 115.5
Then the amount spent on the computer is calculated as,
⇒ 385 - 115.5
⇒ 269.5
The total amount that he will spend on his computer will be $269.5.

In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the
new price for a total of $5.88.
Answer:
original price per pound = $1.21
Step-by-step explanation:
In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the new price for a total of 5.88
write an equation to determine the original price per pound (p)
find the original price per pound
Let
p = original price per pound
3p = original price for 3 pounds
Additional increase = 0.75
Number of pounds = 3
3p + 0.75(3) = 5.88
3p + 2.25 = 5.88
3p = 5.88 - 2.25
3p = 3.63
p = 3.63/3
p = 1.21
original price per pound = $1.21
