Answer:

6x+42

Step-by-step explanation:

So by, "5x+9 , 3x+12" I'm assuming you mean the length and the width.

The perimeter of a rectangle is 2(l+w), so if you put the values in, you get...

2(5x+9+3x+12)

2(8x+21)

6x+42, which is your answer.

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).

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.

Answer: 2 quartz of the blue paint for every 10 quartz of yellow paint

Relation

Step-by-step explanation:

The rule that relates elements of one set to elements of another set is called "Relation". Functions are special types of Relations.

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:

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

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

Step-by-step explanation:

Answer:

Step-by-step explanation:

add all internal angles

∠H + ∠I + ∠J = 180

equation: 3x - 2 + 4x - 9 + 3x - 9 = 180

combine similar terms: 3x + 3x + 4x = 180 + 2 + 9 + 9

simplify: 10x = 200

divide 10 both sides: x = 20

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:

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].

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.
