Answer: Many researchers, engineers and environmentalists are expressing deep concerns about changes in the overall climate of the planet. Fossil fuels are being continuously used to produce electricity. The burning of these fuels produces gases like carbon dioxide, methane and nitrous oxides which lead to global warming. Deforestation is also leading to warmer temperatures. The hazard of global warming is continuously causing major damage to the Earth's environment. Most people are still unaware of global warming and do not consider it to be a big problem in years to come. What most people do not understand is that global warming is currently happening, and we are already experiencing some of its withering effects. It is and will severely affect ecosystems and disturb ecological balance. Because of the treacherous effects of global warming, some solutions must be devised. The paper introduces global warming, elaborates its causes and hazards and presents some solutions to solve this hot issue. Above all, alternative energy sources (solar, wind, hydro, geothermal, bio mass) need to be seriously pursued. Finding and using renewable sources of energy is one of the methods to combat the ever increasing global warming effectively.

Step-by-step explanation:
Answer:
160 inches

1. 20 does not equal 4/5
2. 6x=48 divide 6 on both sides
x=8
Answer:
No and 8
Step-by-step explanation:
The first one is No
4/5 is 0.8, not 20
The second one
6x =48
Divide both sides by 6
6x/6 =48/6
x = 8

Step-by-step explanation:
it takes 2.60 to buy 4 therefore 2.60÷4=.65cents and .65×7= 4.55
Answer:
H. $4.55
Step-by-step explanation:
If 4 croissants costs $2.60
then 1 croissant costs $0.65 (2.6 divided by 4)
Multiply 0.65 by 7 to get how much 7 croissants costs.
Which would give you $4.55.

Which expression is equivalent

Tony writes an equation to represent the distance he walks in meters, d, in relation to the number of minutes he walks, m.
d = 108m
Mark has created a table to record the number of minutes it took him to walk different distances in meters.
Time
(minutes)
Distance
(meters)
10
1,100
20
2,200
40
4,400
Assuming that Tony and Mark both walk at a constant rate, the unit rate for Tony is
meters per minute and the unit rate for Mark is
meters per minute.
On a graph, the line representing Tony’s distance covered with respect to time would be
Mark’s line. So, Tony’s walking speed is
Mark’s.
Answer:
Tony: d = 108m
Tony walks 108 meters per minute
Mark:
(10,1100),(20,2200)
m = (2200 - 1100) / (20 - 10) = 1100/10 = 110 meters per mins
Step-by-step explanation:
So Tony's walk speed is 2 meters per minute slower then Tony's walk speed
Tony : d = 108m.....so Tony walks 108 meters per minute

The points (2, 4) and (-2, -4) are plotted on the coordinate plane using the equation y = a × x. How can you use the coordinates to find the value of a?
Answer:
you can replace the y in the equation with 4 or -4 and the x with 2 or -2.
then make like all equations you want to get a by itself
right now the equation should look like 4= 2a
now you divide 4/2= 2a/2
now the equation looks like this 2=a or a=2
The value of a is 2.
Given that,
The points (2, 4) and (-2, -4) are plotted on the coordinate plane.
Based on the above information, the calculation is as follows:
Here we have to replace the y with 4 or -4 and the x with 2 or -2
So, it should be like
4= 2a
So, a = 2

Which shows the use of the commutative property?
3 (7 + n) = 21 + 3 n
7 + (3 + n) = (7 + 3) + n
3 n + 7 = 7 + 3 n
(7 + 3) + n = 10 + n
Answer:
[tex]3n + 7 = 7 + 3n[/tex]
Step-by-step explanation:
Given
Options (a) to (d)
Required
Determine which uses commutative property
Commutative property states that:
[tex]A + B = B + A[/tex]
From the list of options, only option (c) obeys this property.
[tex]3n + 7 = 7 + 3n[/tex]
Your answer is C.
3n+7=7+3n.

which question can be answered by solving the inequality 8d > 200
answers above
It is the bottom right one because the amount he walked has to be greater than 200
Answer:
Bottom left corner (C)
Step-by-step explanation:
I believe it is C because 8d>200 equals 25. It's hard to explain, but simply because if it wasn't exactly 200, the answer would be different. Let me know if I am incorrect, if I am I am truly sorry.

Hey!! Please solve all CORRECTLY, I'm counting on you guys (i will also give brainliest and 20 points)
Step-by-step explanation:
The first one is B
x < 6 means that x cannot be 6, so only B or D works. But D is x > 6, so it's B
The second one is B
here, a filled circle means that x can be -6, so it's B or D again.
note that for these types of problems, choose a random number and see if it works. Let x = 0. Obviously, it's on the number line blue part, and it is greater than -6, so it's B
The third one is C
she has less than or equal to 45, but 45 is possible, so at most.
The last one is A. h > 4.5 means that h cannot be 4.5
So it's more, not at least.
So it's A
