Since the 1800s, fossil fuels have been used to meet the energy needs of many human activities.

Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.

Group of answer choices

There is more available space for carbon to become fossil fuels.

There is less carbon in storage.

There will be less carbon in the water.

There is more carbon in the atmosphere.

There will be more carbon respired by organisms.

There will be less carbon released through decomposition.

Answers

Answer:

Below.

Step-by-step explanation:

There will be more carbon in the atmosphere.

There is less carbon in storage.

Answer:

1. There is more carbon in the atmosphere.

2. There is more available space for carbon to become fossil fuels.

Step-by-step explanation:

When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign. How many social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2% (ME=0.02)?

Answers

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

Step(i):-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that [tex]\sqrt{p(1-p}\leq \frac{1}{2}[/tex]

Step(ii):-

Given margin of error  = 2 % =0.02

The margin of error is determined by

          [tex]M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }[/tex]

         [tex]0.02 = \frac{\frac{1}{2} }{\sqrt{n} }[/tex]

        [tex]\sqrt{n} =\frac{1}{2 X0.02}[/tex]

        √n = 25

squaring on both sides, we get

       n = 625

The ratio of the side lengths of a triangle is 2:3:4. The shortest side is 15 inches. What is the perimeter? Explain. Pleas show your work. I will give brainiest to the best and first answer

Answers

Ratio of the sides of the triangles,

2 : 3 : 4

Let's consider each side to be

2x,3x and 4x

Therefore the perimeter of the triangle is,

2x + 3x + 4 x = 9x

The shortest side is 15 inches.

We know that the smallest value in the above ratio is 2

Therefore,

2x = 15 inches

x = 7.5 inches

Perimeter of the triangle

= 9x

= 9 * 7.5 inches

= 67.5 inches

the scale on a blueprint for a new apartment is 1 in equals 4 feet if the length of the living room on the blueprint is 6 in, what is going to be the actual length of the living room?

Answers

Answer:

The actual length of the living room is 24 feet.

Step-by-step explanation:

Scaling

The scaling on a blueprint for an apartment is:

1 inch = 4 feet

This means every 1 inch measured on the blueprint corresponds to 4 feet on the real length of the apartment.

We know the length of the living room in the blueprint is 6 inches, thus the real dimension of the living rooms is:

6 * 4 = 24 feet

The actual length of the living room is 24 feet.

Nancy Boone’s new automobile had an MSRP of $27,853.00. The dealer prep charge was $278.50 and the title fee was $25.00. Options totaled $2,375.50. Find the sales tax rate, to nearest hundredth percent, if the total cost was $32,591.22 and the sales tax applied to everything but the title fee.

Answers

Answer:

The sales tax included in the sale of the car is 15.76%.

Step-by-step explanation:

Given that the MSRP of the car bought by Nancy Boone is $ 27,853, and the total cost of the car was $ 32,591.22, including sales tax, plus a dealer prep charge of $ 278.50 and a title fee of $ 25, to find out the percentage of sales tax ( which does not include the title fee) it is necessary to perform the following calculation:

32,591.22 - 25 = 32,566.22

27,853 + 278.5 = 100

32,566.22 = X

28,131.5 = 100

32,566.22 = X

(32,566.22 x 100) / 28,131.5 = X

3,256,622 / 28,131.5 = X

115.76 = X

115.76 - 100 = 15.76

Thus, the sales tax included in the sale of the car is 15.76%.

Answer:

C. middle school grades

Step-by-step explanation:

Colleges want to see if students challenged themselves by taking rigorous courses, and they also want to know what kind of grades students were able to maintain. They also like to take into account the scores you get on standardized tests because these tests can give a relatively accurate idea of a student's mastery of certain subjects. The only thing they don't pay attention to are the grades you earned in middle school. Since these grades aren't very recent, they don't serve as an accurate measure of a student's academic ability, which is why colleges prefer to look at the grades a student earns during their time in high school.

They share the tips in the ratio 2:1:5.
How much more does Brian get over Colin?

Answers

Let 2x = Paul

Let x = Colin

Let 5x = Brian

2x + x + 5x = 78.40

8x = 78.40

x = 78.40 ÷ 8

x = 9.8

Brian gets 5(9.8) which is 49.

Colin gets 9.8.

Brain over Colin means 49/9.8 = 5.

Brain gets £5 more than Colin in terms of a tip.
