sin R =-- ?----
Answers
Answer:
45/51
Step-by-step explanation:
SOH CAH TOA
Sin x = Opposite/hyp
Cos x = Adjacent/hyp
Tan x = Opposite/Adjac
Here we're looking for Sin R, so we want to find opposite side over the hypotenuse.
Thus, [tex]sin R = \frac{45}{51}[/tex]

The head of a nail is circular, as shown. The head of this nail has a diameter of 6 millimeters. Which measurement is closest to the area of the head of this nail in square millimeters?
Answers
Answer: [tex]\boxed{\ 28.26}[/tex]
My step-by-step explanation:
We would use the formula πr2 (pi x radius x radius)2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2
And so we find: 6mm÷2=3mm3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:
πr2= 3.14 x 3 x 3= 28.26mm2Hope this helps you!

To find:
The value of x and then graph on the number line.
Solution:
We have,
[tex]x+19\leq 23[/tex]
Subtracting 19 from both sides, we get
[tex]x+19-19\leq 23-19[/tex]
[tex]x\leq 4[/tex]
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.

Working at papa rons pizza you make 30 per shoft plus 3 per pizza you deliver. If you worked gor bombinoes you eould make 20?Per shift snd 4 per pizza you delivers. How many pizzas do you have to deliver to earb the same amount of money
Answers
Answer: 10 pizzas
Step-by-step explanation:
To answer this you need to equate the formulas of the money earned from both pizzerias.
Assume number of pizzas is x:
Papa rons:
= 30 + 3x
This is the amount one gets for delivering a certain number of pizzas
Bombinoes
= 20 + 4x
Equate them:
30 + 3x = 20 + 4x
30 - 20 = 4x - 3x
x = 10
10 pizzas would earn you the same amount of money.

In ΔPQR, \overline{PR} PR is extended through point R to point S, \text{m}\angle QRS = (10x-1)^{\circ}m∠QRS=(10x−1) ∘ , \text{m}\angle RPQ = (3x+17)^{\circ}m∠RPQ=(3x+17) ∘ , and \text{m}\angle PQR = (2x+12)^{\circ}m∠PQR=(2x+12) ∘ . Find \text{m}\angle QRS.M∠QRS.
Answers
Answer:
<QRS = 55 degrees
Step-by-step explanation:
Given the following
m∠QRS=(10x−1) ∘
∠RPQ=(3x+17) ∘
m∠PQR=(2x+12)
External angle m<QRS = 10x-1
Interior angles are m∠RPQ=(3x+17) ∘ and m∠PQR=(2x+12)
Using the law that the sum of interior angle is equal to exterior
10x + 1 = 3x+17 + 2x + 12
10x+1 = 5x+29
10x-5x = 29-1
5x = 28
x = 28/5
x = 5.6
Get m<QRS
Recall that <QRS = 10x - 1
<QRS = 10(5.6) - 1
<QRS = 56-1
<QRS = 55 degrees
