aluminum production from bauxite ore costs $2000 per ton, whereas aluminum recycling costs $800 per ton. what is the percent saved by recycling?

The value of w is 54 degrees

From the figure, we can see that:

The angle w intercepts the arc that has a measure of 108 degrees

This means that:

w = 0.5 * 108

Evaluate the product

w = 54

Hence, the value of w is 54

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: 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

Answer:

A. 9,006

Step-by-step explanation:

First we need to find 25% of 4,000

4,000/4 = 1000

So we know there are 1,000 mosquitoes a month.

So In 4 months it would be 4,000 more mosquitoes.

That would be 8,000 but i don't see that so I would say A.

Let me know if I'm correct.

.5 × 3.75 1.875

Answer:

-16.875

Step-by-step explanation:

This equation is quite simple and will only require one equation to solve. This is the equation,

-3.75×4.5=-16.875

The final answer is -16.875

[tex] \bf \: Circumference \: of \: a \: circle = 2\pi \: r[/tex]

Area of rectangle = 38.5 cm².

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:

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:

[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
