Answer:

Part a) [tex]y=0.05x+1.50[/tex]

Part b) [tex]y=0.50x+0.50[/tex]

Part c) The graph in the attached figure

Part d) see the explanation

Step-by-step explanation:

The complete question is

A restaurant sells tea for $1.50 plus $0.05 per refill. A gas station store sells tea for $0.50 plus $0.50 per refill.

Part a) Write a linear function for the price of tea at restaurant

Part b) Write a linear function for the price of tea at gas station store

Part c) Graph both equations

Part c) Compare the lines in terms of slope and y-intercept

Let

y -----> the price of tea in dollars

x -----> the number of refills

we know that

The linear equation in slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value (value of y when the value o x is equal to zero)

Part a)

At restaurant

we have that

The slope or unit rate is equal to

[tex]m=\$0.05\ per\ refill[/tex]

The initial value or y-intercept is equal to

[tex]b=\$1.50[/tex]

substitute

[tex]y=0.05x+1.50[/tex]

Part b)

At gas station store

we have that

The slope or unit rate is equal to

[tex]m=\$0.50\ per\ refill[/tex]

The initial value or y-intercept is equal to

[tex]b=\$0.50[/tex]

substitute

[tex]y=0.50x+0.50[/tex]

Part c) Graph both equations

we know that

The easiest way to graph a line is with two points

Find the intercepts of the line

At restaurant

[tex]y=0.05x+1.50[/tex]

The y-intercept is the point (0,1.50)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

[tex]0=0.05x+1.50[/tex]

[tex]x=-30[/tex]

The x-intercept is the point (-30,0)

Plot the points and join to graph the line

see the attached figure

At gas station store

[tex]y=0.50x+0.50[/tex]

The y-intercept is the point (0,0.50)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

[tex]0=0.50x+0.50[/tex]

[tex]x=-1[/tex]

The x-intercept is the point (-1,0)

Plot the points and join to graph the line

see the attached figure

Part c) Compare the lines in terms of slope and y-intercept

The slope or unit rate at the restaurant is less than the slope at the gas station store

[tex]\$0.05\ per\ refill < \$0.50\ per\ refill[/tex]

The initial value or y-intercept at the restaurant is greater than the initial value at the gas station store

[tex]\$1.50 > \$0.50[/tex]

The solutions to the equation 9x^2 - 54x = 0 are x = 0 and x = 6, found by factoring and setting each factor equal to zero.

To find the solution(s) to the equation 9x2 - 54x = 0, we can start by factoring out the greatest common factor, which is 9x. This gives us:

9x(x - 6) = 0

Now, we set each factor equal to zero:

From the first equation, we divide by 9 to isolate x:

x = 0

From the second equation, we add 6 to both sides:

x = 6

Thus, the solutions to the equation are:

_______

Alice earned $39,188 last year.

_______

Best Regards,

Wolfyy :)

Answer:

The correct answer is 39,188.

Step-by-step explanation:

Alice Swanson's current earnings for this year are 40,400. Her earnings were 3% less than this last year. To find her earnings for last year, we will use the "Percent • Whole = Part" formula. But first, we must put 3% into a decimal form: 3 ÷ 100 = 0.03. Now let's solve:

40,400 • 0.03 = 1,212

1,212 is 3% of 40,400. To find Alice's earnings for last year, we will subtract her raise from her current earnings:

40,400 - 1,212 = 39,188

Hope this helps,

♥A.W.E.S.W.A.N.♥

Let's begin by understanding your initial position, which is the school, located at coordinates (2, -1). The school is 2 blocks east and 1 block south of the center of town. This means that if you were to go to the center of town, you would travel 2 blocks west and 1 block north from the school. Now, to find out where your house is in relation to the school, we can reverse the steps you take to get from your house to the school. You’ve said you walk 5 blocks west and 2 blocks north to reach the school. Since you walk west to reach school, your house must be to the east of the school. Similarly, since you walk north to reach school, your house must be to the south of the school. To get back to your house from the school, then, you'd need to reverse both of these movements. To find the house’s position, we start with the school's position at (2, -1): 1. Since you walk 5 blocks west to get to school, let's go 5 blocks east from the school to get back to your house. Moving east means increasing the x-coordinate. So, starting from the x-coordinate of the school, which is 2, we add 5 to find the x-coordinate of your house. This gives us 2 + (-5) = -3. 2. Next, since you walk 2 blocks north to get to school, let's go 2 blocks south from the school to reach your house. Moving south means decreasing the y-coordinate. So, starting from the y-coordinate of the school, which is -1, we subtract 2 to find the y-coordinate of your house. This gives us -1 + 2 = 1. Therefore, the coordinates of your house are (-3, 1), which means your house is 3 blocks west and 1 block north of the center of town.

Final answer:

To locate the student's house on a grid, you need to reverse the movements made from the school to the house. By subtracting 5 blocks west and adding 2 blocks north from the school's coordinates (2, -1), the house's coordinates are determined to be (-3, 1).

Explanation:

The question involves a two-dimensional path on a grid, similar to the coordinates and movements given in the examples provided. To solve the problem, imagine that you start at the center of town, move 2 blocks east and 1 block south to reach the school at (2, -1), and then move from your house to the school by walking 5 blocks west and 2 blocks north.

To find your house's coordinates, you need to reverse the movements. Starting from the school's location at (2, -1), moving 5 blocks west means subtracting 5 from the x-coordinate, and moving 2 blocks north means adding 2 to the y-coordinate. Thus, the coordinates of your house would be (2 - 5, -1 + 2) which simplifies to (-3, 1).

Answer:

in 2hrs =  -6°C

in 5hrs = -15°C

in half an hr = -1.5°C

Step-by-step explanation:

in an hr, the temperature falls by 3°C = 0 -3 = -3°C

in 2hrs = 2*-3°C = -6°C

in 5hrs = 5*-3°C = -15°C

in half an hr = 0.5 * -3°C = -1.5°C

The required continues to fall at this rate of the temperature in 2 hours -6°C ,5hours in -15°C and in half an hour -1.5°C.

Given that,

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour.

We have to find,

If it continues to fall at this rate, what will the temperature be in 2 hours 5 hours and in half an hour.

According to the question,

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour.

In an hour the temperature falls by 3°C = 0 - 3 = -3°C

The temperature fall in 2hrs = (2)(-3°C) = -6°C

The temperature fall in 5hrs = (5)(-3°C) = -15°C

The temperature fall in half an hour = (0.5)(-3°C) = -1.5°C

Hence, The required continues to fall at this rate of the temperature in 2 hours -6°C ,5hours in -15°C and in half an hour -1.5°C.

Answer:

  x = 2

Step-by-step explanation:

The equation shown is a perfectly good equation.

___

Look at what is being done to the variable. It is multiplied by 2, and 4 is added to the product.

To find the value of the variable, we reverse these operations, in reverse order. We undo the addition by adding the opposite of 4 (to both sides of the equation).

  2x +4 -4 = 8 -4

  2x = 4 . . . . . simplify

We undo the multiplication by multiplying by the inverse value, 1/2 (to both sides of the equation).

Answer:

$2.50

Step-by-step explanation:

Let the original monthly expenses be 'x'.

Given:

Reduced monthly expenses = $2.125

Reduction in monthly expenses = 15%

Therefore, remaining percentage of monthly expenses = 100 - 15 = 85%

Now, as per question:

[tex]85\%\ of\ x=2.125\\\frac{85}{100}\times x=2.125\\0.85x=2.125\\x=\frac{2.125}{0.85}=\$2.50[/tex]

Therefore, the original monthly expenses of Mr. Wood was $2.50.

Also, we can find his monthly income using the value of 'x'.

As per question, his monthly expenses is 80% of his income.

So, 80% of income = 2.5

Income = [tex]\frac{2.5}{0.80}=\$3.125[/tex]

So, his monthly income is $ 3.125

The solution involves calculating the average speed for each driver (distance travelled divided by time). Deena's average speed was 65 mph and Kristen's was 55 mph, therefore, Deena drove at a faster rate.

To solve this question, we need to compute each driver's average speed. Average speed is calculated by dividing the total distance traveled by the total time taken to cover that distance. Mathematically, average speed = total distance/total time.

For Deena, we calculate her average speed by dividing her total distance traveled (585 miles) by the time she took to cover this distance (9 hours). Doing the division, we find Deena's average speed to be about 65 mph.

Similarly, for Kristen, we divide her total distance traveled (605 miles) by the time she took to cover this distance (11 hours). Kristen's average speed comes out to be approximately 55 mph.

By comparing the average speeds, we find Deena drove at a faster rate than Kristen.

Also, [tex]P(-2)=0[/tex]

Since, for [tex]x=-2[/tex], [tex]P(x)[/tex] is 0, therefore, [tex]x+2[/tex] is a factor of the polynomial.

Now, let us divide the given polynomial by [tex]x+2[/tex] using long division method. Therefore,

Answer:

The time taken by ball to hit the ground is 5.10 seconds .

Step-by-step explanation:

Given as :

The height cover by ball to move upward = 7 feet

The initial velocity = u = 50 feet per sec

Let the time taken by ball to hit the ground = t sec

Let the deacceleration rate = - 9.8 m/s²

The final velocity of the ball = v=  0 at the top

So, From equation

v = u + at

I.e v = u + a × t

Or, 0 = 50 + ( - 9.8) × t

Or, 9.8 t = 50

∴ t = [tex]\frac{50}{9.8}[/tex]

I.e t = 5.10 seconds

So, time taken = 5.10 sec

Hence The time taken by ball to hit the ground is 5.10 seconds . Answer

A 1:4 solution has a concentration of 1/(1+4) = 1/5 or 20%.

Similarly, a 1:20 solution has a concentration of 1/(1+20) = 1/21 or 4.76%.

If x is the mL of 20% solution and y is the mL of water, then:

x + y = 600

1/5 x = 1/21 (600)

Solve:

x = 5/21 (600)

x ≈ 143

y ≈ 457

Answer:

the third side is 40 m long

Step-by-step explanation:

The perimeter of the triangle is the sum of its three sides, and they give you what that value in meters is (120 m)

Your are given the length of two of them: 30 m and 50 m, and need to find the third one (let's call it "x" for this unknown side)

Now set the following equation:

Perimeter = side 1 + side 2 + side 3   --> replace these with the info you know

120 m = 30 m + 50 m + x   --> add 30 m and 50 m obtaining 80 m

120 m = 80 m + x  --> now solve for x (isolate the x on one side) by subtracting 80 m from both sides

120 m - 80 m = x  --> perform the subtraction 120 m - 80 m = 40 m

40 m = x

Which tells us that the third unknown side has a length of 40 m

Answer:

The third side is 40 meters long

Step-by-step explanation:

From the question, we were told that a triangular courtyard has a perimeter of 120 meters, we are to find the length of the third side if the other two sides are 30 and 50 meters.

First, we need to know that perimeter is the distance around a polygon.

Let the third side = side c, let the two sides be side A and side B

Perimeter = side A + side B + side c

side A = 30 meters

side B = 50 meters

side C = ?

Perimeter = 120 meters

We can now proceed to insert the values in the equation above

Perimeter = side A + side B + side c

      120    = 30 + 50 + side c

      120 = 80 + side c

Subtract 80 from both-side of the equation

120 - 80 = 80 - 80 + side c

40 = side c

side c = 40 meters

Therefore, the third side is 40 meters long

Now,  d = 4.5 - L  = 4.5  - (-12)  = 16.5

 or,  d = 16.5

Hence, the solution of the given system is given as  L = -12, d =16.5
