Answer:1/4

Step-by-step explanation:

I got it right.

Fraction of time that the Snowy Pines get at least 14 inches of snow is 1/4.

Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.

Given is a box and whisker plot.

We know that box plot represents the first quartile, median and third quartile of the data set.

First quartile is where the 25% of the data points lie.

Median is where the 50% of the data points lie.

Third quartile is where 75% of the data points lie.

Above 14 inches lie the third or upper quartile.

75% of the data points lies below 14.

Data points which are at least 14 inches is 14 or more than 14.

Snowy Pines get at least 14 inches of snow for 100% - 75% = 25% of data points.

Fraction = 25/100 = 1/4

Hence the required fraction of time is 1/4.

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]

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.

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:

Step-by-step explanation:

Simplify this problem by dividing all three terms by 2:

x^2 + 20 = -4x

Rewrite this in standard form:

x^2 + 4x + 20

Take the coefficient of the x term and divide it by 2:  4/2 = 2

Square this result:  2^2 = 4

Between x^2 + 4x  and  20  add this 4, then subtract it:

x^2 + 4x + 4 - 4

Rewrite x^2 + 4x + 4 as the square of a binomial:

(x + 2)^2 - 4, or (x + 2)^2 = 4

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 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

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

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 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%.
