A. multiply through by the L.C.M (4).

Answer:

2x +2y= 123, or

8a +2x +2y= 191

Step-by-step explanation:

Perimeter of rectangle= 2(length) +2(width)

Let the length and the width of the picture be x and y respectively.

Perimeter of the picture= 2x +2y

2x +2y= 123 -----(1)

Let the width of the border be a.

Length of picture frame= a +x +a= 2a +x

Width of the picture frame= a +y +a= 2a +y

Outer perimeter of the frame= 191

2(2a +x) +2(2a +y)= 191

Expand:

4a +2x +4a +2y= 191

8a +2x +2y= 191 -----(2)

Substitute (1) into (2):

8a +123= 191

8a= 191 -123

8a= 68

a= 68 ÷8

a= 8.5 cm

Thus the width of the border is 8.5 cm.

Answer:

Step-by-step explanation:

This is a proportional question. If you learn how to keep things together, they are not only easy to do, they are mechanical: they are all done exactly the same way.

tanks of gas             different tanks of gas          

==========     =         ================

hours                                  different hours.

initial tank of gas = 3/4 tank

initial hours = 9/2 = 4.5 hours

final tanks of gas = X

final time = 12 hours.

Solution

3/4                            x

====         =      ==============

4.5                           12

Cross multiply

4.5x = 12*3/4                      Combine the right

4.5x = 36/4                        Simplify  

4.5x = 9                              Divide both sides by 4.5

x = 9/4.5

x = 2

So she will need 2 tankfuls.

The relationship between p(n) and n is given by p(n) = 0.0005n

An equation is an expression used to show the relationship between two or more numbers and variables.

Let p represent the weight in pounds and n represent the weight in tons.

1 pound = 0.0005 ton, hence:

p(n) = 0.0005n

The relationship between p(n) and n is given by p(n) = 0.0005n

Answer:

If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .

Consider the sum of the measures of the exterior angles for an n -gon.

N=180n−180(n−2)

Distribute 180 .

N=180n−180n+360 =360.

Answer:

10.8 on hostas

Step-by-step explanation:

I don't know exact answer

Using the dot product:

For any vector x, we have

||x|| = √(x • x)

This means that

||w|| = √(w • w)

… = √((u + z) • (u + z))

… = √((u • u) + (u • z) + (z • u) + (z • z))

… = √(||u||² + 2 (u • z) + ||z||²)

We have

u = ⟨2, 12⟩   ⇒   ||u|| = √(2² + 12²) = 2√37

z = ⟨-7, 5⟩   ⇒   ||z|| = √((-7)² + 5²) = √74

u • z = ⟨2, 12⟩ • ⟨-7, 5⟩ = -14 + 60 = 46

and so

||w|| = √((2√37)² + 2•46 + (√74)²)

… = √(4•37 + 2•46 + 74)

… = √314 ≈ 17.720

Alternatively, without mentioning the dot product,

w = u + z = ⟨2, 12⟩ + ⟨-7, 5⟩ = ⟨-5, 17⟩

and so

||w|| = √((-5)² + 17²) = √314 ≈ 17.720

  -1701

Step-by-step explanation:

The recursion relation tells you each term of the sequence is -3 times the previous term. Then the first 6 terms are ...

  7, -21, 63, -189, 567, -1701

The value of f(6) is -1701.

The explicit formula for a geometric sequence with first term 7 and common ratio -3 is ...

  f(n) = 7×(-3)^(n-1)

Then f(6) is ...

  f(6) = 7×(-3)^5 = 7×(-243) = -1701

Answer:

Step-by-step explanation:

Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC

Recall the Law of Cosines

[tex]a^2=b^2+c^2-2bc\cdot cos(A)[/tex]

Identify angles and sides

[tex]m\angle A=23^\circ\\a=BC=?\\b=AC=14\\c=AB=6[/tex]

Solve for side "a"

[tex]a^2=b^2+c^2-2bc\cdot cos(A)\\\\a^2=14^2+6^2-2(14)(6)\cdot cos(23^\circ)\\\\a^2=196+36-168cos(23^\circ)\\\\a^2=222-168cos(23^\circ)\\\\a=\sqrt{222-168cos(23^\circ)}\\ \\a\approx8.2[/tex]
