Answer:

The sales tax percentage is 2%.

Step-by-step explanation:

With the information provided, you can find the sales tax percentage by subtracting the retail price from the amount the customer paid and dividing that by the retail price. Then, you have to multiply the result by 100.

((58.14-57)/57)*100= (1.14/57)*100=0.02*100= 2%

According to this, the answer is that the sales tax percentage is 2%.

Answer:

Brian's rate is 15 km/hr

Adrian's rate is 16 km/hr

Step-by-step explanation:

Let r = Brian's rate

   r + 1 = Adrian's rate

4/r = Brian's time

4/(r + 1) = Adrian's time

The difference in times is 1 min = 1/60 hr

[tex]\frac{4}{r} - \frac{4}{r + 1} = \frac{1}{60}[/tex]     LCD = 60r(r + 1)

4(60)(r + 1) - 4(60)r = r(r + 1)

240r + 240 - 240r = [tex]r^{2}[/tex] + r

[tex]r^{2}[/tex] + r - 240 = 0

(r - 15)(r + 16) = 0

r = 15    or   r = -16

Since the rate cannot be negative, Brian's rate is 15 km/hr and Adrian's rate is 16 km/hr

answer: C is the answer for your the question

Given statement solution is :- The set of ordered pairs (-1, -3) and (5, 5) determine a line with a slope of 4/3, according to the given statement's answer.

To determine the slope of a line given two ordered pairs (x1, y1) and (x2, y2), we use the formula:

slope is equal to y2 - y1 / x2 - x1.

Let's calculate the slopes for each set of ordered pairs:

A. (5, -3) (2, 3)

slope = (3 - (-3)) / (2 - 5)

= 6 / (-3)

= -2

B. (3, 10) (-3, -2)

slope = (-2 - 10) / (-3 - 3)

= -12 / (-6)

= 2

C. (3, -5) (-3, -7)

slope = (-7 - (-5)) / (-3 - 3)

= (-2) / (-6)

= 1/3

D. (-1, -3) (5, 5)

slope = (5 - (-3)) / (5 - (-1))

= 8 / 6

= 4/3

Option D's set of ordered pairs, (-1, -3) and (5, 5), results in a line with a slope of 4/3.

The correct answer to the exercise is:

Step-by-step explanation:

To obtain the surface area of a circle, you can use the formula:

Where:

How you can see, in the picture gives you a straight line that passes through the circle side by side, the circle radius is half of that value, then:

Now, we can replace the values in the first formula:

Answer:

[tex]Area = 216\pi[/tex]

Step-by-step explanation:

Given

See attachment for semicircles

Required

The area of the paper

First, calculate the area of each petal.

The petal is made up of:

1. Semicircle of diameter 12cm

2. Semicircle of diameter 18cm (i.e. 12cm + 6cm)

3. A hole semicircle of diameter 6cm

The area of each semicircle is calculated as follows:

[tex]Area = \frac{\pi r^2}{2}[/tex]

For (1):

[tex]d = 12cm[/tex] --- diameter

[tex]r = 0.5 * d = 0.5* 12cm = 6cm[/tex] --- radius

So:

[tex]A_1 = \frac{\pi * 6^2}{2}[/tex]

Evaluate the exponent

[tex]A_1 = \frac{\pi * 36}{2}[/tex]

Divide 36 by 2

[tex]A_1 = 18\pi[/tex]

For (2):

[tex]d = 18cm[/tex]

[tex]r = 0.5* 18cm = 9cm[/tex]

So:

[tex]A_2 = \frac{\pi * 9^2}{2}[/tex]

[tex]A_2 = \frac{\pi * 81}{2}[/tex]

[tex]A_2 = 40.5\pi[/tex]

For (3):

[tex]d = 6cm[/tex]

[tex]r = 0.5* 6cm = 3cm[/tex]

So:

[tex]A_3 = \frac{\pi * 3^2}{2}[/tex]

[tex]A_3 = \frac{\pi * 9}{2}[/tex]

[tex]A_3 = 4.5\pi[/tex]

Recall that (3) is a hole.

So, the area (A) of a petal is:

[tex]A = A_1 + A_2 - A_3[/tex]

[tex]A = 18\pi + 40.5\pi - 4.5\pi[/tex]

[tex]A = 54\pi[/tex]

The paper uses 4 petals.

So:

[tex]Area = 4 * A[/tex]

[tex]Area = 4 * 54\pi[/tex]

[tex]Area = 216\pi[/tex]

Answer:

750 systems are  needed in 20 years to clean 150 million tons wastes.

Step-by-step explanation:

Total waste = 150 million tons

Waste cleaned each year by 1 machine = 10,000 tons

No of years from 2020 to 2040 =  20 years

Waste cleaned in 20 years by 1 machine = 20* 10,000= 200,000 tons

Machines needed in 20 years to clean 150 million tons wastes using

y= mx      ( where m= number of machines)

and x is the waste cleaned in 20 years by 1 machine

150,000,000 = m 200,000

or m = 150,000,000 /200,000

m= 750

Answer: the answer is B

Step-by-step explanation:

Answer:

Step-by-step explanation:

Vertical angles are equal.  Thus, 3x + 14 = 5x, and 14 = 2x.

Then x must be 7.

The first angle, 3x + 14, is 3(7) + 14, or 35.

The second, 5x, is 5(7) = 35

As expected, the two angles are equal.

Answer:

Both angles are 35°

Step-by-step explanation:

Vertical angles are when they equal each other so:

3x + 14 = 5x

5x - 3x = 14

2x = 14

x = 7

5x

5(7) = 35

3x + 14

3(7) + 14

21 + 14 = 35

Answer:

The proportionality constant is 2/5

Step-by-step explanation:

Here, we want to get the proportionality constant

Let us view the two points as being points on a line

The constant of proportionality will be the slope of the line that connects the two points

Mathematically, we can use the formula for the slope of a line

We have this as;

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

(x1,y1) = (20,8)

(x2,y2)= (25,10)

m = (10-8)/(25-20) = 2/5
