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 .

Researchers at Manchester Metropolitan University in England determined experimentally that if a piece of toast is dropped from a 2.5 foot high table, the probability that it lands butter side down is 0.81.
A) Explain what this probability means.
B) If you dropped 100 pieces of toast, will exactly 81 of them land butter side down? Explain
C) Maria decides to test this probability and drops 10 pieces of toast from a 2.5 foot table. Only 4 of them land butter side down. Should she be surprised? Describe how you would carry out a simulation to answer this question, assuming the probability that the toast lands butter side down is 0.81. Do not perform the simulation.
D) The dot plot displays the results of 50 simulated trials of dropping 10 pieces of toast. Does the simulation suggest that Maria should be surprised? Explain.

12x + 15y = 9
−12x − 18y = −6
PLEASE I NEED EXPLANATION THANKS
Answers
Answer:
x = 2
y = –1
Step-by-step explanation:
We need to solve this system of equations for the point where the two linear equations intersect. That means solving for one variable, then using that to solve for the other. But, I'm looking at this, and...
Well, I see an easy way to isolate y right now! See how one equation has 12x and the other has –12x? Adding the two equations together will cancel them out!
That gives us this equation:
12x – 12x + 15y – 18y = 9 – 6 — adding the expressions together
15y – 18y = 9 – 6 — cancel out the 12x
–3y = 3 — simplify the equation
–3y ÷ 3 = 3 ÷ 3 — divide by 3 to isolate y
y = –1 — simplify the equation
Now that we have our y-value, we can substitute into the equation and solve for x. I'm substituting into both to make sure y = –1 is part of the solution point (on a coordinate plane, this is where the functions intersect).
12x + 15y = 9 — original equation
12x + 15(–1) = 9 — substitute –1 for y
12x – 15 = 9 — simplify
12x – 15 + 15 = 9 + 15 — add 15 on both sides to isolate 12x
12x = 24 — simplify
12x ÷ 12 = 24 ÷ 12 — divide by 12 on both sides to isolate x
x = 2 — simplify
That's one equation. Let's check the other with these values to make sure (2, –1) is the solution point.
–12x – 18y = –6
–12(2) – 18(–1) ≟ –6
18 – 24 ≟ –6
–6 = –6 ✓
Yep, this is the solution we're looking for!
Hope this helps you understand the concept! Have a great day!

9. Jamie ha ahorrado $ 42 del dinero de su asignación para comprar libros. Si compra 5 libros a d dólares por libro, le quedarán 42 5d de su asignación. ¿Cuánto le queda si los libros cuestan $ 3.50 cada uno?
Answers
Answer:
$24.50
Step-by-step explanation:
Jamie has saved $ 42 of his allowance money to buy books. If you buy 5 books at d dollars per book, you will have 42- 5d left of your allowance. How much is left if the books cost $ 3.50 each?
We have the equation
42 - 5d = Amount of Allowance left
d = 3.50
Hence:.42 - 5 × 3.50
= $42 - 17.5
= 24.5

Answers
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.
