Answer:
The answer is in the explaination
Step-by-step explanation:
A + B = 180 degrees
14x - 72 = 180
14x = 108
x = 8
A = 5 times 8 plus 20
A = 60
Answer:
110 degrees.
Step-by-step explanation:
Angle A + Angle B = 180 degrees.
Therefore, 5x+20+9x-92=180
When you solve you get 14x=252 or x=18
When you plug that into A you get 5(18)+20=110
Therefore, A=110 degrees

6) Two coastguard stations P and Q are 17km apart, with due East of P. A ship S is observed in distress on a bearing 048° fromP and 324 from Q. How far is the ship from each of the coastguard stations?
Answers
Answer:
The ship S is at 10.05 km to coastguard P, and 12.70 km to coastguard Q.
Step-by-step explanation:
Let the distance of the ship to coastguard P be represented by x, and its distance to coastguard Q be represented by y.
But,
<P = 048°
<Q = [tex]360^{o}[/tex] - [tex]324^{o}[/tex]
= 0[tex]36^{o}[/tex]
Sum of angles in a triangle = [tex]180^{o}[/tex]
<P + <Q + <S = [tex]180^{o}[/tex]
048° + 0[tex]36^{o}[/tex] + <S = [tex]180^{o}[/tex]
[tex]84^{o}[/tex] + <S = [tex]180^{o}[/tex]
<S = [tex]180^{o}[/tex] - [tex]84^{o}[/tex]
= [tex]96^{o}[/tex]
<S = [tex]96^{o}[/tex]
Applying the Sine rule,
[tex]\frac{y}{Sin P}[/tex] = [tex]\frac{x}{Sin Q}[/tex] = [tex]\frac{z}{Sin S}[/tex]
[tex]\frac{y}{Sin P}[/tex] = [tex]\frac{z}{Sin S}[/tex]
[tex]\frac{y}{Sin 48^{o} }[/tex] = [tex]\frac{17}{Sin 96^{o} }[/tex]
[tex]\frac{y}{0.74314}[/tex] = [tex]\frac{17}{0.99452}[/tex]
⇒ y = [tex]\frac{12.63338}{0.99452}[/tex]
= 12.703
y = 12.70 km
[tex]\frac{x}{Sin Q}[/tex] = [tex]\frac{z}{Sin S}[/tex]
[tex]\frac{x}{Sin 36^{o} }[/tex] = [tex]\frac{17}{Sin 96^{o} }[/tex]
[tex]\frac{x}{0.58779}[/tex] = [tex]\frac{17}{0.99452}[/tex]
⇒ x = [tex]\frac{9.992430}{0.99452}[/tex]
= 10.0475
x = 10.05 km
Thus,
the ship S is at a distance of 10.05 km to coastguard P, and 12.70 km to coastguard Q.

Step-by-step explanation:
A contractor hires 4 workers for a construction project. Each worker is paid $12 per hour. The contractor also buys 20 cubic yards of concrete for the project, at a price of $160 per cubic yard. Which equation best describes the contractor’s total cost, C, if the project takes h hours to complete?
C = (4 x 12)h + (20 x 160)
C = 4(12 + 160)h + 20
C = (20 x 160)h + (4 x 12)
C = 12h + (20 x 160)
Answers
Answer:
The answer is C.
Step-by-step explanation:
4 x 12 is how much money per worker per hour. 20 x 160 is how much the cost for the concrete. Adding them gets you the total cost.
Hope this helped!
The equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)
Given:
Number of workers = 4
Earnings of each work = $12
Yards of concrete = 20 cubic yards
Cost per cubic yards = $160
let
C = total cost
h = number of hours needed to complete the project
C = (Number of workers + Earnings of each work)number of hours + (Yards of concrete + Cost per cubic yards)
C = (4 × 12)h + (20 + 160)
Therefore, the equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)

Here,
p = 10000
r = 5% = 5/100 = 0.05
n = 1
t = 2
[tex]a = 10000(1 + \frac{0.05}{1} ) {}^{1 \times 2} [/tex]
[tex]a = 10000(1.05) {}^{2} [/tex]
[tex]a = 10000(1.1025)[/tex]

add stuff
6x+126=180
subtract 126 from both sides
6x=54
divide 6 from both sides
