Sine Rule
[tex]\sf \dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Question 1
The interior angles of a triangle sum to 180°

Given:
A = 55°B = 35°C = 90°c = 20[tex]\implies \sf \dfrac{a}{\sin 55}=\dfrac{b}{\sin 35}=\dfrac{20}{\sin 90}[/tex]

Answer:
The answer is 192.33
Step-by-step explanation:
A coaster measures 7 cm in diameter. The total area of five roller coasters must be determined.
The diameter of the coaster is d = 7 cm
The radius is:
[tex]r =[/tex] [tex]\frac{d}{2}[/tex]
[tex]=[/tex] [tex]\frac{7}{2}[/tex] [tex]cm[/tex]
[tex]= 3.5[/tex] [tex]cm[/tex]
The area of the circle is:
[tex]A =[/tex] [tex]\pi r^{2}[/tex]
= (3.14 x 3.5^2) [tex]cm^{2}[/tex]
[tex]= 38.465[/tex] [tex]cm^{2}[/tex]
We now know that the area required for five coasters is 5 x 38.465 [tex]cm^{2}[/tex]
[tex]= 192.325[/tex] [tex]cm^{2}[/tex]
Round 192.325 to the nearest hundredth and you'll get 192.33 as the correct answer.

Given l\parallel m\parallel nl∥m∥n, find the value of x.
Answers
Answer:
x = 57
Step-by-step explanation:
x - 5 and 2x + 14 are angles on the same side of the transversal between two parallel linesThey are supplementary [add up to 180°]x - 5 + 2x + 14 = 1803x + 9 = 1803x = 171x = 57The value of x is 57.
What are properties of parallel lines?Properties of Parallel Lines
The pairs of corresponding angles are equal.The pairs of vertically opposite angles are equal.The pairs of alternate interior angles are equal.The pairs of alternate exterior angles are equal.Given:
lime m || n
So, using the property of parallel lines we have the angles on the same side of transversal are supplementary
x- 5 + 2x +14= 180
3x + 9 = 180
3x = 171
x= 171/3
x= 57
Hence, the value of x is 57.

Eddie purchased 15 boxes of paper clips and 7 packages of index cards for a total of $55.40. Finn bought 12 boxes of paper clips and 10 packages of index cards for $61.70. Find the cost of one box of paper clips and one package of index cards
Answers
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
Step-by-step explanation:
Eldora and Finn went to an office supply store together
Eldora bought 15 boxes of paper clips and 7 packages of index cards for a total cost of $55.40
Finn bought 12 boxes of paper clips and 10 packages of index cards for a total cost of $61.70
We need to find the cost of one box of paper clips and the cost of one package of index cards
Assume that the cost of one box of paper clips is $x and the cost of one package of index cards is $y
∵ x represents the cost of one box of paper clips
∵ y represents the cost of one package of index cards
∵ Eldora bought 15 boxes of paper clips and 7 packages of
index cards for a total cost of $55.40
∴ 15x + 7y = 55.4 ⇒ (1)
∵ Finn bought 12 boxes of paper clips and 10 packages of
index cards for a total cost of $61.70
∴ 12x + 10y = 61.7 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -10 and equation (2) by 7 to eliminate y
∵ -10(15x) + -10(7y) = -10(55.4)
∴ -150x - 70y = -554 ⇒ (3)
∵ 7(12x) + 7(10y) = 7(61.7)
∴ 84x + 70y = 431.9 ⇒ (4)
Add equations (3) and (4)
∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)
∴ -66x = -122.1
- Divide both sides by -66
∴ x = 1.85
Substitute the value of x in equation (1) or (2) to find y
∵ 12(1.85) + 10y = 61.7
∴ 22.2 + 10y = 61.7
- Subtract 22.2 from both sides
∴ 10y = 39.5
- Divide both sides by 10
∴ y = 3.95
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

Answer:
Reflected along x axis
Translated 7 units to the right
A transformation of a point is the movement of the point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.
Figure ABCD has A at (- 4, 4), B at (- 2, 2), C at (- 2, - 1), D at (- 4, 1).
If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)
If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:
It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)
It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Question 7 options:
x > −3
x < −3
x > 3

Answers
Answer:
[tex]\boxed{\sf{D. \quad x < 3}}[/tex]Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
-4x-8>-20First, add by 8 from both sides.
[tex]\sf{-4x-8+8 > -20+8}[/tex]
Solve.
-20+8=-12
Rewrite the problem down.
[tex]\sf{-4x > -12}[/tex]
Multiply by -1 from both sides.
(-4x)(-1)<(-12)(-1)
Solve.
Multiply the numbers from left to right.
(-12)(-1)=12
4x<12
Divide by 4 from both sides.
4x/4<12/4
Solve.
Divide the numbers from left to right.
12/4=3
x<3
Therefore, the correct answer is D. x<3 (last option).I hope this helps you! Let me know if my answer is wrong or not.

Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.

slope = (50 - 0) / (2 - 0) = 50/2 = 25
y = mx + b
slope(m) = 25
and since u have point (0,0), ur y int (b) = 0
so ur equation is y = 25x + 0 which is written as y = 25x...which is basically saying that he travels 25 miles per hr
how far will he travel in 24 hrs.....so sub in 24 for x
y = 25(24)
y = 600 miles
in summary : The dependent variable is distance, the equation is y = 25x and the dragonfly will fly 600 miles.
