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.

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.

Answer:

tens

Step-by-step explanation:

The first thing we need to do is calculate the quotient. This would be the answer of dividing the number of coupons by the number of total stores.

769 / 9 = 85.4

If we count the first digit from the left as the first digit then that would mean 8 is the first digit and it is in the tens spot while the 5 is in the Ones spot.

(x-4)(3x+2) is your answer

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:

A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.

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:

n>-5

Step-by-step explanation:

We have to distribute the -7 first, so:

-105<-7(5-2n) becomes:

-105<-35+14n

To find n, we have to add 35, so:

-105<-35+14n

+35   +35

We get 14n>-70. Now, we have to divide each side by 14 to find n.

14n/14>-70/14.

So, the solution becomes n>-5.

JKL = 108 degrees

KLJ = 27 degrees

LJK = 45 degrees

Step-by-step explanation:

Add all the values of the triangle angles together to get 20. Then divide 180 by  20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).

JKL = 12x = 12(9) = 108

KLJ = 3x = 3(9) = 27

LJK = 5x = 5(9) = 45

1. use sin

inverse of sin(44/57) = 50.5 ---> 51°

2. use tan

inverse of tan(6/8) = 36.8 ---> 37°

3. use cos

inverse of cos(20/31) = 49.8 ---> 50°

4. use sin

inverse of sin(37/58) = 39.6 ---> 40°

55,000 milliliters

Step-by-step explanation:

So if washing machine uses 5 times more than dishwasher

Dishwasher: 11 litters of each cycle

Washing machine: 11 x 5= 55 litters for each machine in litters

If 1 litter is equal to 1000 milliliter then 55 x 1000 = 55,000 milliliters

FORMULA for milliliter: multiply the volume value by 1000

Answer: Your answer is 30 percent

Answer:

30%

Step-by-step explanation:

Make a fraction

6/20

There a few different ways to find a percentage, but in this case, I will change the fraction to be out of 100

20 × what = 100?

20 × 5 = 100

Multiply the denoninator by 5

6 / 20 × 5

What we do to the denominator, we must also do to the numerator

6 × 5 / 20 × 5

30/100

Percentages are out of 100, meaning if the fraction has the denominator "100," the numerator is the answer

30%

Gwen had 27 bites altogether. She had 15 on her legs and 12 on her arm

An equation shows the relationship between two or more numbers and variables.

Let x represent the mosquito bites on leg and y represent the bites on arms.  She counted 5 mosquito bites on her legs for every 4 bites on her arms, hence:

x/y = 5/4

4x = 5y

4x - 5y = 0     (1)

Also,  Gwen had 3 more mosquito bites on her legs than on her arms, hence:

x = y + 3    (2)

From both equations:

x = 15, y = 12

x + y = 15 + 12 = 27

Gwen had 27 bites altogether
