Around half of the electricity used in the United States is powered by burning coal. The United States is a developed country with a high level of carbon emissions. Select TWO realistic actions that could help to provide energy for the United States and also help to lower carbon emissions.
A
Create more fossil fuels.
B
Build additional power plants.
C
Reduce the demand for energy.
D
Use renewable sources of energy.
E
Make products that are more efficient.
F
Develop technology to better harvest fossil fuels.
Answers
The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.
How to reduce carbon emissionThe burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.
In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.
Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.
By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.
Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.

A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 6 members of the team are hard at work in their separate households, preparing their presentations. What is the probability that none of them has lost electricity in his/her household? Assume that their locations are spread out so that loss of electricity is independent among their households.
Round your response to at least three decimal places.
Answers
The probability that none of them has lost electricity in his/her household is 64.7%.
ProbabilityGiven:
Electricity wiped =P=7%
Team members= n=6 members
Hence;
P(x = 0) = (6C0)(0.07^0)(1-0.07)^6
P(x = 0)= (1)(1)(0.93)^6

A store clerk is paid $10.75/ hour and a store assistant manager is paid $16.25/ hour. How long would it take the store managerto make $500 or more than the store clerk? Round to the nearest hour. Show all work.
Answers
10.75x + 500 = 16.25
500 = 5.5x
x = 91 hours
Check:
10.75 * 91 = 978.25
16.25 * 91 = 1478.75
1478.75 - 978.25 = 500.5 :)
It will take approximately 91 hours for the store manager to make $500 or more than the store clerk.
If the store clerk is paid $10.75/ hour and the store assistant manager is paid $16.25/ hour, the difference in their pay per hour will be expressed as:
The difference in the amount earned per hour = 16.25 - 10.75
The difference in the amount earned per hour = $5.5
This means that the store assistant manager will collect $5.5 more than the store clerk in one hour. This can be expressed as:
$5.5 = 1 hour
To determine how long it will take the store manager to make $500 or more than the store clerk, we can write:
$500 = x
Divide both expressions:
[tex]\dfrac{5.5}{500} =\dfrac{1}{x} \\Cross \ multiply\\5.5x = 500 \times 1\\5.5x = 500\\x=\frac{500}{5.5}\\x= 90.9 \ hours[/tex]
This means that it will take approximately 91 hours for the store manager to make $500 or more than the store clerk.

The length of CE is 3.6 and the radius of the circle is 2
The length of CEStart by calculating the length of AD using:
AD^2 = AC^2 - CD^2
This gives
AD^2 = 10^2 - 6^2
AD^2 = 64
Take the square roots
AD = 8
Represent CE with x.
So:
AE = 10 - x
Calculate ED using:
ED^2 = CD^2 - CE^2
ED^2 = AD^2 - AE^2
So, we have:
AD^2 - AE^2 = CD^2 - CE^2
This gives
8^2 - (10 - x)^2 = 6^2 - x^2
Expand
64 - 100 + 20x - x^2 = 36 - x^2
Add x^2 to both sides
64 - 100 + 20x = 36
Evaluate the like terms
20x = 72
Divide by 20
x = 3.6
Hence, the length of CE is 3.6
The radius of the circleThe equation is given as:
x^2 + y^2 + 6x + 5y = -45/4
Rewrite as:
x^2 + 6x + y^2 + 5y = -45/4
Take the coefficients of x and y
Divide them by 2, square the result and add the result to both sides.
So, we have:
x^2 + 6x + (6/2)^2 + y^2 + 5y + (5/2)^2= -45/4+ (6/2)^2 + (5/2)^2
This gives
x^2 + 6x + (6/2)^2 + y^2 + 5y + (5/2)^2= 4
Express as perfect squares
(x + 3)^2 + (y + 5/2)^2 = 4
The circle equation is represented as:
(x - a)^2 + (y - b)^2 = r^2
Where r represents the radius
By comparison, we have:
r^2 = 4
This gives
r = 2
Hence, the radius of the circle is 2

How many liters each of a 50% acid solution and a 75% acid solution must be used to produce 90 liters of a 60% acid solution? (Round to two decimal places if necessary.)
Answers
The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
What is the litters about?Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.

A
Glacial runoff will begin earlier in the year, and as a result, streams will also warm earlier. Warmer streams will affect native fish populations.
B
Glacial melt and warmer temperatures will increase humidity levels in the ecosystem. This will decrease fish populations that thrive in colder climates.
C
Glacial loss will cool parts of the ecosystem, but because overall temperatures are warmer, precipitation will increase. Increased rain will raise stream and lake levels and increase fish populations.
D
Glaciers will melt into nearby bodies of water. The water levels will rise and create an overall cooling effect on the ecosystem, resulting in a net zero temperature change. The fish population will be unaffected.
E
Glaciers will melt into nearby oceans, causing the salt levels of the ocean to go down. This will increase the available habitat for fish and cause an increase in the nearby population.
