Step-by-step explanation:
For the current reaction, 2NO2 ↔ N2O4, we have:
Kc = [tex]\frac{[N_{2} O_{4}]}{[NO_{2}]^{2} }[/tex]
Concentration of NO2 = 11.95
Concebtration of N2O4 = 6.05
Based on the current concentrations of NO2 and N2O4, what is Kc?

Which recursive formula fits the following pattern? 50, 25, 12.5, 6.25, 3.125...
Answer:
1.5625
Step-by-step explanation:
Find the ratio (r) between adjacent members: 50,25,12.5,6.25,3.125
a_2/a_1=25/50=0.5
a_3/a_2=12.5/25=0.5
a_4/a_3=6.25/12.5=0.5
a_5/a_4=3.125/6.25=0.5
The ration (r) between every two adjacent members of the series is constant and equal to 0.5 thus:
a_6 =a_1×(^r6-1) =a_1×r^5 =50×0.5^5 =1.5625

find the value of x..
Answer:
B x = 7
Step-by-step explanation:
You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.
So if you go the side that matches the one you need to solve, it's 2.5.
2.5 times 4 = 10 so that bigger pentagon side should equal 10.
The equation x-3 = 10
which means x is 7

Solve the following:
a) 2(5x – 3) = 24
b) 5(2x + 1) = 50
Answer:
x = 3 and x = [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
(a)
2(5x - 3) = 24 ( divide both sides by 2 )
5x - 3 = 12 ( add 3 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
(b)
5(2x + 1) = 50 ( divide both sides by 5 )
2x + 1 = 10 ( subtract 1 from both sides )
2x = 9 ( divide both sides by 2 )
x = [tex]\frac{9}{2}[/tex]

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
a. -4 and 4b + 4
b. 3x and 1 -3x
Answer:
Does this problem have a picture, I just need to make sure I am seeing everything correctly thanks!
Step-by-step explanation:
a. -4 and 4b + 4 = 4b
-4 and 4b + 4 = -4 + (4b + 4) = 4b + (4 - 4) = 4b + 0 = 4b
b. 3x and 1 - 3x = 1
3x and 1 - 3x = 3x + (1 - 3x) = 1 + (3x - 3x) = 1 + 0 = 1

given mtw=bgk find the values of x and y
Answer:
x = 12
y = 8
Step-by-step explanation:
to solve for x you would set up your equation:
4x - 3 = 45
then solve using algebra:
4x - 3 = 45
4x = 48
x = 12
to solve for y set up your equation as:
11y + 6 = 94
TO GET 94: you will need to subtract 41 and 45 from 180 to get 94.
(each triangle equals 180 and we need the 3rd measure)
solve the equation:
11y + 6 = 94
11y = 88
y = 8

What's at stake?
Forests are cradles of life—around four-fifths of all land species live in tropical forests. They play a vital role in regulating our climate by absorbing carbon dioxide, and help maintain our soil and water.
Forests directly support around 1.6 billion people—nearly a quarter of the world's population. And we all rely on them for the air we breathe and the countless products they provide.
But over the last half-century, people have destroyed forests at an alarming rate. We've already lost around half of the world's original forests.
The story so far
In the early 1990s, we campaigned to stop the timber industry destroying and degrading the world's forests.
At the time, few businesses believed they were responsible for where their timber came from. Those that did claim to sell products from well-managed forests had no way of proving it.
"Businesses didn't think the environment was their concern," recalls Jean-Paul Jeanrenaud, who led WWF-UK's work on forests at the time.
"We had chief executives slamming the phone down on us. I even had people threaten to punch me."
How things have changed… In September 1991, British DIY chain B&Q committed to working with us to buy only legal, sustainable timber. By the end of that year, 16 large UK companies had committed to sourcing their timber products from well-managed forests.
That was the beginning of our Global Forest & Trade Network. Today, it's a global partnership of some 275 retailers, producers, community groups and other organizations from across the forest industry supply chain. Members are committed to safeguarding the world's forests and the communities, economies and ecosystems that depend on them.
But we needed a way to turn those commitments into reality. So in 1993, we helped form the Forest Stewardship Council (FSC) to certify timber and wood-based products that meet high environmental and social standards.
For a forest to be FSC certified, independent inspectors check that it meets the FSC's strict criteria. All trees that are cut down have to be replaced or allowed to re-grow naturally, and parts of the forest are left untouched. The rights of indigenous people are respected, and local workers are employed on a decent salary. Often, companies support other social services, such as schools and clinics.
Inspectors also check every stage along the supply chain, so you can be sure that any product that bears the FSC logo is good for forests, people and wildlife.
Did you know?
Just 10 years ago, only 300 sq km of forest in Russia was FSC-certified. Today, it's 260,000 sq km—a quarter of its commercial forests.
Facts and stats
1.4 million sq km—area of forest certified by the FSC. That's an area more than twice the size of France
81—number of countries with FSC-certified forests
40 percent—forest area of Europe and North America certified by the FSC
US$73bn—annual sales of forest-based products by members of our Global Forest & Trade Network
What next?
Almost a tenth of forest products traded now meet FSC standards. That's a phenomenal rate of growth—but it means nine-tenths of products are still uncertified.
We believe some areas of forest need to be protected from any commercial logging. But we're supporting responsible forestry alongside protected areas to help conserve the world's most important forests:
In the Congo Basin, the largest area of tropical forest after the Amazon, 45,000 sq km is now FSC certified—and we're working with everyone from heads of state on down to increase this. As well as protecting important habitats for elephants, great apes and many other species, sustainable forestry is improving livelihoods for some of the poorest people on the planet.
In Borneo, we're working to conserve and restore the "Heart of Borneo," a 220,000 sq km area of the island's species-rich rainforest. Responsible forestry is a vital aspect of this: some 20,000 sq km is already FSC certified or in the process of certification. By 2020, we want the entire Heart of Borneo area to be protected or managed sustainably.
In the western Mediterranean, people have sustainably harvested cork for centuries. Cork oak forests provide a haven for rare plants, birds and other wildlife, including the Iberian lynx, the world's most endangered wild cat. We're promoting FSC certification to keep sustainable cork harvesting economically viable and help protect this unique landscape.
What you can do
You can help secure a future for the world's forests, and the people and animals that depend upon them next time you buy a table—or any other wood-based product.
Only buy products with the FSC label—it's the only credible certification scheme.
If you don't see the logo, ask the store or manufacturer why not. Make sure they realize that you as a customer want to know that the products you buy don't destroy forests. This message will swiftly get back to their suppliers.

Allison lives 380 miles from her grandmother. She plans to drive to her grandmother's house for the weekend. She will drive an average of 60 miles per hour. Which equation represents the distance (d) Allison has left to drive after h hours?
A. D=380+60h
B. D=(380-60)h
C. D=380-60h
D. D=380h-60
Answer:
its b
Step-by-step explanation:
The equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're given that:
Allison lives 380 miles from her grandmotherShe will drive an average of 60 miles per hour. Distance that Allison has left to drive represented by 'd' (in miles) after h hours.In 1 hour, she averagely covers 60 miles.
In h hours, she averagely covers [tex]60 \times h[/tex] hours
d = distance remaining for her to reach to her grandmother's home after h hours of driving
d = Total distance - distance traveled in h hours
d = 380 - 60×h
(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, so 60×h can be simply written 60h)
Thus, the equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h
