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:

Step-by-step explanation:

1) multiply the three dimension

V = 7 x 2 x 4 = 56 cm^3

2)  find the base area

base area = (9 x 3)/2 = 13,5 km^2

multiply the base area for the height

V = 13,5 x 5 = 67,5 km^3

3) find the trapezoid area

trapezoid area = [(base 1 + base 2) x h]/2 = [(4+6) x 1.7]/2 = 8.5 cm^2

mutiply the trapezoid area for the height that the priam would assume if the base will touch the ground

V = 8.5 x 4 = 34 cm^3

4) find the base area

base area = radius^2 x pi = 2^2 x pi = 12,57 yd^2

multiply the base area for the height

V= 12.57 x 6 = 75.40 yd^3

5) find the base area

base area = 9^2 x pi = 81 x pi = 254.47 ft^2

multiply the base area for the height

V = 254.47 x 5 = 1272.35 ft^3

6)  multiply the three dimensions

V = 12 x 11 x 9 = 1188 yd^3

7) find the trapezoid area

trapezoid area = [(12+6) x 6.3]/2 = [20 x 6,3]/2 = 63 in^2

mutiply the trapezoid area for the height that the priam would assume if the base will touch the ground

V = 63 x 16 = 1008 in^3

8) find the base area

base area = (leg1 x leg 2)/2 = (4 x 3)/2 = 6 m^2

multiply the base area for the height

V = 6 x 9 = 54 m^3

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:

Pay for 40 hours would be [tex]\geq 40 * 148[/tex]

Step-by-step explanation:

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

Pay for 40 hours would be [tex]\geq 40 * 148[/tex]

Answer: 1/12

Step-by-step explanation:

1. Add up the 3 parts making 12

3:4:5 = 3+4+5=12

2. Out of the ratio we know that Colin gets 5 parts which is 5/12

3. If we subtract 5/12 from 1/3 we should get an answer of 1/12

5/12-1/3 =1/12

Step-by-step explanation:

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:

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

Answer:

x = 44
