Answer:

[tex]MN = 18[/tex]  

Step-by-step explanation:

Given

[tex]AB = 9[/tex]

[tex]BD = x + 1[/tex]

[tex]MB = x - 1[/tex]

[tex]BN = 15[/tex]

See attachment

Required

Determine MN

The products of the segments of two chords that intersect are always, equal.

So, we have:

[tex]AB * BD = MB * BN[/tex]

[tex]9 * (x + 1) = (x - 1) * 15[/tex]

Open bracket

[tex]9x + 9 = 15x - 15[/tex]

Collect like terms

[tex]15x - 9x = 9 + 15[/tex]

[tex]6x = 24[/tex]

Solve for x

[tex]x = \frac{24}{6}[/tex]

[tex]x = 4[/tex]

The length of MN is calculated as:

[tex]MN = MB + BN[/tex]

[tex]MN = x - 1 + 15[/tex]

Substitute [tex]x = 4[/tex]

[tex]MN = 4 - 1 + 15[/tex]

[tex]MN = 18[/tex]

Answer:

a=76 b=83

Step-by-step explanation:

for a. we divide 6688(area) by 88 to find the width bc 88*w=6688

6688/88 is 76 so a=76

Since 312 is perimeter we have to subtract 73 twice and then divide that by 2 bc 73+73+L+L=312

(312-73-73)/2=83 so b=83

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:

[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: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:

5/2 cm

Step-by-step explanation:

Given that:

Area of triangle = 25/12 cm

Height of triangle = 5/3 cm

Let,

Length of the base = b

Recall :

Area of a triangle = 1/2 * base * height

Substitute the values above into the equation :

25 /12 = 1/2 * b * 5/3

25 /12 = 5b/ 6

Using cross multiplication

25 * 6 = 12 * 5b

150 = 60b

Divide both sides by 60 to isolate b

150/60 = 60b / 60

b = 5/2 cm

Gabe works for 4 hours and earns $ 1,120

Pay for one hour is [tex]\frac{1120}{4} = 280[/tex]

When he works for 10 hours, he earns $1480.

Pay for one hour is

[tex]\frac{1480}{10} = 148[/tex]

Thus the per hours pay must be greater than or equal to 148 dollars
