Which linear equation can be derived from this proportion?

Answer:

1 and 7/8 is the change.

Step-by-step explanation:

First, make the bottom to fractions have the same denominator so we can figure out the length of the other route. 2 and 3/8 will become 2 and 9/24.

Then 3 and 5/6 will become 3 and 20/24. Add them both to get 6 and 5/24. since we cant simplify it stays the same. so now we convert the other number for the new road so it can match the old route. 4 and 1/3 become 4 and 8/24. Now we finish off by subtracting our two numbers to get 1 and 21/24. Since we can simplify the number now becomes 1 and 7/8.

Hope this helped.

No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.

Answer:

  no

Step-by-step explanation:

A triangle is scalene when its sides have three different lengths. Your triangle has two sides with the same measure, so it is isosceles, not scalene.

Answer:

no

Step-by-step explanation:

Parallelograms have zero lines of symmetry because it is impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other.

Answer:

Technical answer no

BUT

if you are in a college/postgraduate level group theory class yes

Step-by-step explanation:

Imagine a square, and imagine 4 lines across the top, the side, and the two diagonal ones. Because the two diagonal lines of symmetry are technically the same, there are only three possible lines.

if you are in the group theory class,  comment and ill give a lengthy answer on that.

Answer:

1.41 x 10^-2

Step-by-step explanation:

1.8 x 10^-2 - 3.9 x 10^-33 = 18 x 10^-3 - 3.9 x 10^-3

                                        = (18-3.9) x 10^-3

                                        = 14.1 x 10^-3

                                        = 1.41 x 10^-2

Step-by-step explanation:

[tex]a = \sqrt{b - a} [/tex]

firstly square

[tex] \sqrt{b- a} [/tex]

to get a-b on it's own

it's now

[tex]a = b - a[/tex]

now plus the a to cancel out the minus a to get

[tex]a {}^{2} = b[/tex]

which can also be written as

[tex]b = a {}^{2} [/tex]

Answer

720

Step-by-step explanation:

10 x 18 = 180

2 x 2 = 4

180 x 4 = 720

We can identify the sides of a right triangle by describing their location in relation to a given angle.

There are three basic trigonometric ratios:

We use theta (θ) to represent an angle.

We are asked to find [tex]\cos(\beta)[/tex] in the triangle.

[tex]\cos\theta=\dfrac{adjacent}{hypotenuse}[/tex]

The side adjacent to β measures 8 units.

The hypotenuse of the right triangle measures 17 units.

[tex]\cos\beta=\dfrac{8}{17}[/tex]

Therefore, [tex]\cos\beta=\dfrac{8}{17}[/tex].

Triangle formula bxh/2

3x6/2=9

Answer: Shown below

Step-by-step explanation:

Since it's a square, we will refer to its values as x. Using that, we can make an equation for the rectangle.
(x + 15) * ( x - 13) = 60

We can expand it and simplify so that we get a zero on one side and a polynomial on the other.

(x + 15)(x - 13) - 60 = 0

x² + 2x - 225 = 0

We simplify the binomial so we get two answers for x.

(x - 15)(x + 17) = 0

x = 15 and -17

Now we have two answers. So which one is right? Well, the sides cannot be negative, therefore we must use 15 and not -17.

15² = 225

Our answer is 225

Answer:

270°

Step-by-step explanation:

Answer:

f(h(-1)) = - 11 or D

Step-by-step explanation:

h(-1) = -2(-1)^2 - 3(-1) + 1

h(-1) = -2(1) + 3 + 1

h(-1) = 2

f(2) = (2t + 7)/(t - 3)

f(2) = (2*2 + 7) / (2 - 3)

f(2) = 11/-1

f(2) = - 11

Be very careful how you handle this. The way I have done it will work, but it does not work all the time.

The sure way to handle this is to put(h(n)) every place you can on the right side of f(t)

f(h(n)) = (2(h(n) + 7)) /  (h(n) - 3)

When we rationalise the expression 5 / 2√2, the result obtained is 5√2 / 4

a / √b  = (a / √b) × (√b / √b)

5 / 2√2 = (5 / 2√2) × (√2 / √2)

Clear bracket

5 / 2√2 = 5√2 / (2×2)

Simplify

5 / 2√2 = 5√2 / 4

Thus, we can conclude that the value of 5 / 2√2 is equivalent to 5√2 / 4

Answer:

[tex](5-7y)(y+8)[/tex]

Step-by-step explanation:

Factoring out y + 8:

[tex]5(y+8) - 7y (y + 8)=(5-7y)(y+8)[/tex]

Answer:

Since the total population will be 9.4B people

W + A+ A =9.4B

W = 0.6B + A/4  

A+ 2.9B = As

A - 2.9B + As + 0.6 + A/4 = 9.4B

(9/4)*A= 11.7B

A = (4/9)*11.7B=5.2B

W = 0.6B + (5.2B/4) = 1.9B

A = 5.2B - 2.9B = 2.3B

Answer:

  4w+8 feet

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of its sides. Since opposite sides are identical in length, it can be computed as double the sum of adjacent side lengths. Here, the lengths are in feet.

  P = 2(L+W)

  P = 2((w+4) +w)

  P = 4w +8

The perimeter of the patio is 4w+8 feet.

Answer:

(C) -7x - 5y = -48

Step by step explanation:

We look for the equation of the line AB

We have then:

y-yo = m (x-x0)

m = (y2-y1) / (x2-x1)

m = (4 - (- 1)) / (4 - (- 3))

m = 5/7

We choose an ordered pair:

(xo, yo) = (4, 4)

Substituting:

y-4 = (5/7) (x-4)

y = (5/7) x-20/7 + 4

7y = 5x - 20 + 28

7y = 5x + 8

y = (5/7) x + 8/7

The equation of the perpendicular line is:

-7x - 5y = -48
