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.

We can conclude that -

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

Given is a parallelogram ABCD.

Now, we can state that -

∠A = ∠C

(y + 10) = (2y - 40)

y + 10 = 2y - 40

y = 50

{Opposite angles are congruent}

(4x) + (2y - 40) = 180

4x = 180 - 60

4x = 120

x = 30

{Consecutive angles are supplementary}

Therefore, we can conclude that -

Answer:

Steps to find the equation of a line from two points:

Find the slope using the slope formula

Use the slope and one of the points to solve for the y-intercept (b).

One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.

Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

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:

8.2 units

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]

Therefore, the length of line segment BC is about 8.2 units

Answer:

No, it can exceed 3

Step-by-step explanation:

the variable could be anything from 600 to 600 million and when you double it's only going to get bigger.

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
