find the measure of angle L this is the last question mark brainest ty so much xx
Answers
Answer:
∠L = 50°
Step-by-step explanation:
∠R = 109°
∠U is supplementary to ∠R
This means ∠R + ∠U = 180°
109° + ∠U = 180°
Subtract ∠R from 180° to get ∠U
∠U = 81°
A triangle's angles must add up to 180, so if we take ∠U + ∠E, we figure out what 2 of the 3 angles add up to, we can then subtract this sum from 180 to figure out ∠L
81° (This is ∠U) + 49° (This is ∠E) = 130°
180° (Sum of all of a triangle's angles) - 130° (Sum of ∠U and ∠E) = 50° (∠L)
Answer:
∠L = 60°Step-by-step explanation:
see attached image.
add all internal angles and equal to 180
∠U + ∠L + ∠E = 180
∠U = 180 - 109
= 71
plug in values from equation:
∠U + ∠L + ∠E = 180
71 + ∠L + 49 = 180
∠L = 180 - 49 - 71
∠L = 60

"a" varies directly as the square of "b" and inversely as the cube of "c". If a=171 when b=8 and c=9, find a if b=9 and c=6. Round your answer to two decimal places if necessary.
Answers
Answer:
a = 730.43
Step-by-step explanation:
The formula for this type of problem is [ a = kb²/c³ ].
We are given a = 171, b = 8 and c = 9.
Solve for k.
171 = k(8)²/(9)³
k = 1947.80
Solve for a since we found k using b = 9 and c = 6.
a = (1947.80)(9)²/6³
a = 730.425
Round to the nearest hundredth.
730.425 → 730.43
Best of Luck!
Answer:
730.42
Step-by-step explanation:
a varies directly with the square of b, and inversely with the cube of c. Therefore:
a = k b² / c³
where k is the constant of proportionality.
a = 171 when b = 8 and c = 9. So the value of k is:
171 = k (8)² / (9)³
k ≈ 1947.8
So the value of a when b = 9 and c = 6 is:
a = 1947.8 (9)² / (6)³
a ≈ 730.42

Answers
Answer:
2 quartz of the blue paint for every 10 quartz of yellow paint
Step-by-step explanation:
The graph shows the possible different amount of yellow paint and blue paint, in quartz, that can be mixed to obtain a shade of green paint.
On the graph, at the point with the coordinates pair of (2, 10), it means for we would require 2 quartz of blue paints to be mixed with every 10 quartz of yellow paint in order to get the shade of the green paint that we are looking for.

What are the coordinates of the point (−1, 6) after a reflection across the x-axis
Answers
Answer:
(-1,-6)
Step-by-step explanation:
Because it is reflecting across the x-axis, the x value remains the same but the y value moves down the axis the same distance it was, meaning that the y part of the coordinate becomes the opposite.
For example, if (1,2) was reflected across the x-axis, it becomes (1,-2).
If an investment account starts with $3900, and grows with 2.1% interest, compounded continuously. How much is the account worth after 10 years? Round your answer to the nearest dollar. Do NOT round until you have calculated the final answer.
Answers
Answer:
If they are asking amount it is $4800.893013; $4800 (nearest dollar)
If they are asking the amount for interest is $900.8930129; $900 (nearest dollar)
Step-by-step explanation:
Compound interest Formula:
Amount = principle( 1+ rate/100)^n
Information from the question.
-So how you put it is the principle is $3900; the rate is 2.1%; the n is 10.
How to apply it?
- Just substitute in the values;
Amount=3900(1+2.1/100)^10
=4800.893013
~4800 ( nearest dollar)
》That is for amount.
Interest=4800.893013-3900
=900.893013
~900 ( nearest dollar)
》That is for interest.

3(x+2) = 2x+3
3x + 6 = 2x + 3
3x + 6 - 2x = 2x +3 - 2x
X+6 = 3
X+6 - 6 = 3-6
x = -3
Answers
Answer:
Distribution is used from steps 1-2
They eliminate 2x by subtracting it on both sides (steps 3-4)
They eliminated 6 by subtracting it from both sides (steps 5-6)
(steps 3-6 is eliminating like-terms)
Thus this leaves the answer being x=-3
Step-by-step explanation:
Equation 3(x+2) = 2x+3 solved using distributive property and simplification, final solution is x = -3.
Let's identify the reason for each step in the solution to the equation 3(x+2) = 2x+3:
Distributive Property
The first step applies the Distributive Property,
which states that multiplying a number outside the parentheses by the terms inside the parentheses.
Here, we multiply 3 by (x+2),
3(x+2)
= 3 × x + 3 ×2
= 3x + 6
Combining Like Terms
In the second step, combine like terms on both sides of the equation.
On the left side, we have 3x, and on the right side, we have 2x.
We also have constants 6 on the left side and 3 on the right side.
3x + 6 = 2x + 3
Move Variables to One Side
To solve for 'x', we want all the terms with 'x' on one side of the equation.
Here, move the term with 2x to the left side by subtracting 2x from both sides of the equation:
3x + 6 - 2x = 2x + 3 - 2x
Simplify
On the left side, the term 2x cancels out with the 2x on the right side, leaving us with:
x + 6 = 3
Move Constants to the Other Side
To isolate 'x', we need to get rid of the constant term on the left side.
Subtracting 6 from both sides of the equation:
x + 6 - 6 = 3 - 6
Simplify
On the left side, the +6 and -6 cancel out, leaving us with:
x = -3
Final Solution
After simplifying, find that the value of 'x' that satisfies the original equation is x = -3.
This means that if we replace 'x' with -3 in the equation, it will hold true:
3(-3 + 2) = 2(-3) + 3
-3 = -6 + 3
-3 = -3
And that's why the solution to the equation is x = -3.
Therefore, the reason required for solving the equation are distributive property and simplification which gives solution is x = -3

The midpoint of a line segment is (−3,2). One endpoint of the line segment is (4,−7).
What are the coordinates of the other endpoint of the line segment?
Answers
Answer:
The other endpoint is (9, −6)
Step-by-step explanation:
(x1,y1)=(3,2) and M=(6,−2)
x1+x22=x and y1+y22=y
3+x22=6 and 2+y22=−2 ←×2
3+x2=12 and 2+y2=−4
x2=9 and y2=−6
The coordinates of the other endpoint of the line segment are [tex]Y(x,y) = (-10, 11)[/tex].
Vectorially speaking, the midpoint of a line segment is determined by the following expression:
[tex]M(x,y) = \frac{1}{2}\cdot X(x,y) + \frac{1}{2}\cdot Y(x,y)[/tex] (1)
Where:
[tex]M(x,y)[/tex] - Midpoint.[tex]X(x,y)[/tex], [tex]Y(x,y)[/tex] - Endpoints of the line segment.If we know that [tex]M(x,y) = (-3, 2)[/tex] and [tex]X(x,y) = (4, -7)[/tex], then the coordinates of the other endpoint is:
[tex]\frac{1}{2}\cdot Y(x,y) = M(x,y) -\frac{1}{2}\cdot X(x,y)[/tex]
[tex]Y(x,y) = 2\cdot M(x,y) -X(x,y)[/tex]
[tex]Y(x,y) = 2\cdot (-3,2)-(4,-7)[/tex]
[tex]Y(x,y) = (-6, 4) - (4, -7)[/tex]
[tex]Y(x,y) = (-10, 11)[/tex]
The coordinates of the other endpoint of the line segment are [tex]Y(x,y) = (-10, 11)[/tex].

Emma wants to stain a circular deck that has a diameter of 12 m. The cost of the wood stain is $3.25
per square meter.
To the nearest dollar, how much will it cost Emma to stain the entire deck?
Use 3.14 for
Answers
Answer:
$1469
Step-by-step explanation:
diameter of deck = 12 m
diameter = 2*radius
thus
12 m = 2*radius
radius = 12m / 2 = 6 m
area of circle is given by [tex]\pi r^{2}[/tex]
where r is the radius
thus, area of given deck with radius = 12 m
[tex]\pi r^{2} = 3.14*12^{2} \\=> 3.14*144 = 452.16[/tex]
Thus, area of given deck is 452.16 meter square
given
The cost of the wood stain is $3.25 per square meter
cost of 1 meter square wood stain = $3.25
since we have to find to stain the entire deck which has area 452.16 meter square , we multiply both side of equation by 452.16
cost of 452.16 meter square wood stain = $3.25*452.16 = $1469.25
Thus,
it will cost $1469 to the nearest dollar for Emma to stain the entire deck
