20% is equivalent to the decimal .2

Then multiply .2 x 45

45(.2) = 9

Answer:

Step-by-step explanation:

common difference d = a₂-a₁ = (-2x+7)-(5x+2) = -7x+5

a₁₄ = a₁+13(-7x+5)

 = (5x+2) - 91x + 65

 = -86x + 67

Answer:

6 9 4  7

Step-by-step explanation:

i teach math

Step-by-step explanation:

Given

f(x) = 8x - 9

Then

For a.

f(3y - 1 ) = 8(3y - 1 ) - 9

= 24y - 8 - 9

= 24y - 17

Now for b.

f(x) = - 23

or, 8x - 9 = - 23

8x = - 23 + 9

8x = - 14

x = - 14 / 8

x = - 7 / 4

Hope it will help :)

Step-by-step explanation:

step 1. the difference between x -> x' was 7

step 2. the difference between y -> y' was -2

step 3. the translation was 7 right and -2 down

step 4. the translation can be written (x + 7, y - 2)

step 5. the pre image was located in quadrant II.

The counter example to the assertion given is  Parallel Lines , Option B is the correct answer.

Lines which never meet and the distance between them always remains constant are called Parallel Lines.

The statement given is

Two lines in a plane always intersect in exactly one point.

The counter example of the statement will be the lines that never meet , and such lines are Parallel Lines.

Therefore Option B is the correct answer.

Step-by-step explanation: w=7 btw (if u need it)

Brainliest?

The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30

Where 27w represents the cost of w walks.

Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

Answer:

n = 12 , m = 5

Step-by-step explanation:

since it is said it is a parallelogram so opposite sides are equal

n = 12 (being opposite sides of parallelogram)

m + 1 = 6 (being opposite sides of parallelogram)

m = 6 - 1

m = 5

Given:

One midsegment of an equilateral triangle.

To find:

The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.

Solution:

All sides of an equilateral triangle are same.

Let a be the each side of the equilateral triangle.

Length of the midsegment is equal to the half of the non included side or third side.

[tex]Midsegment=\dfrac{a}{2}[/tex]

The sum of two side is

[tex]a+a=2a[/tex]

Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is

[tex]\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}[/tex]

[tex]\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}[/tex]

[tex]\text{Required ratio}=\dfrac{a}{4a}[/tex]

[tex]\text{Required ratio}=\dfrac{1}{4}[/tex]

[tex]\text{Required ratio}=1:4[/tex]

Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.

Answer:

58.69 gallons is the maximum she can get.

Step-by-step explanation:

165 + 2.3g ≤ 300

subtract 165 from both sides

2.3g ≤ 135

divide by 2.3 on both sides

g ≤ 58.6956521739

Answer:

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Step-by-step explanation:

Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:

[tex]20 = a\cdot b^{0}[/tex] (1)

[tex]720 = a\cdot b^{2}[/tex] (2)

By dividing (2) by (1), we obtain the value for [tex]b[/tex]:

[tex]\frac{720}{20} = b^{2}[/tex]

[tex]b = \sqrt{\frac{720}{20} }[/tex]

[tex]b = 6[/tex]

And the value for [tex]a[/tex] is found by (1):

[tex]a = 20[/tex]

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Answer:

√53

Step-by-step explanation:

hypotenuse (h) = √89

base (b) = 6

perpendicular (p) = ?

we know by using Pythagoras theorem

p = √(h² - b²)

= √(√89)² - 6²

= √ 89 - 36

= √ 53
