Answer:
x = 51
Step-by-step explanation:
The figure shown is a pentagon
The angles in a pentagon add up to equal 540
Which means that 77 + 107 + 156 + 149 + x = 540
^ ( note that we just created an equation that we can
use to solve for x )
We then solve for x using that equation
77 + 107 + 156 + 149 + x = 540
step 1 combine like terms
77 + 107 + 156 + 149 = 489
we now have 489 + x = 540
step 2 subtract 489 from each side
489 - 489 cancels out
540 - 489 = 51
we're left with x = 51

Answers
Answer:
17.205 miles
Step-by-step explanation:
Since these directions form a 90-degree angle, we can use the Pythagorean Theorem.
14^2 + 10^2 = c^2
196 + 100 = c^2
296 = c^2
It doesn't have a perfect square root, you can either say that it is [tex]\sqrt{296}[/tex] or approximately 17.205 miles.

why is solar power a renewable energy source
Answers
Answer:
Solar energy is a renewable resource, meaning it won't ever run out or be in short supply. ... Solar energy reaches us via the sun's rays, while fossil fuels come from ancient carbon-rich remains on earth. So, as long as the sun is shining, solar energy will be around.
Step-by-step explanation:
Explanation:
A renewable energy source is simply one that won't run out. This means that you can consistently use it to produce energy and unlike fossil fuels, it won't use up supplies. For this reason, renewable energy often comes from cycles (like that of the tides) or from a constant in the environment. An example of a non-renewable energy source is fossil fuels. We will one day (in the not so far future) run out of fossil fuels as they take millions of years to produce, and we use so much of them up.
Renewable energy sources are getting more and more in demand as we run out of fossil fuels and realise their effect on the atmosphere. Here are a few well known examples.
Solar energy - this is where the energy from the sun is harnessed to produce electricity, or directly heat houses. By creating a panel with a large surface area and heat absorbent surface, it can absorb a large amount of the suns thermal and light energy to either heat up water in pipes (which will then heat houses), or to create electricity by "exciting" electrons (small particles which play a large part in transporting energy) in silicon using the sun's rays (or photons). However, solar energy can be a little unreliable as it requires clear skies and sunlight.
Wind - you may have seen large wind turbines along coastlines. This is because coasts receive a lot of wind, which can provide a force strong enough to turn a large turbine - then connected to a generator allowing us to harness the energy of the wind and turn it into electricity. Again, due to it relying on the weather, this is not a method that will 100% produce energy all the time.
Tidal - this is perhaps one of the most reliable methods, as we can rely on the tide coming in and out each day. It works by building a large dam across an water body affected by the tide. In order for the water to move in the direction it wants to, it has to push it's way through a turbine. The turbine is moved by the water and in turn drives a generator.
This is similar to hydroelectric, where instead of the tide, the energy of water flowing downhill is used to turn the turbine.
I hope this helped, let me know if you need any more information or something explained a bit better:)

There are 363 students at Meadowbrook High School. There are 10 more
freshmen than sophomores, 20 more juniors than sophomores, and seven more
seniors than freshmen. How many seniors are there at the school?
Answers
Freshmen = x + 10
Sophomores = x
Juniors = x + 20
Seniors = (x + 10) + 7 = x + 17
Then, the total number of students = 363, so we’ll make an equation that adds them all up in terms of x to equal 363
(x + 10) + x + (x + 20) + (x + 17) = 363
Combine like terms:
4x + 47 = 363
Subtract 47 from both sides:
4x = 316
Divide both sides by 4:
x = 79
The question was how many seniors there are. Seniors were x + 17, so 79 + 17 = 96

100 students are interviewed to see which of biology, chemistry or physics they prefer.
39 of the students are girls. 21 of the girls like biology best.
16 of the boys prefer physics.
11 out of the 34 who prefer chemistry are girls.
What percentage of the students prefer biology?
Answers
Answer:
43% of the students prefer biology
Step-by-step explanation:
Among girls:
39 of the students are girls.
21 of the girls like biology best.
Boys:
100 - 39 = 61 are boys.
16 prefer physics
11 out of the 34 who prefer chemistry are girls, so 34 - 11 = 23 are boys.
61 - (16 + 23) = 22 prefer biology.
What percentage of the students prefer biology?
21 boys and 22 boys, that is, 43 students out of 100. So
43*100%/100 = 43%
43% of the students prefer biology

Step-by-step explanation:
Most people complain that they gain weight during the December holidays. To find out how much, we sample the weights of 23 adults in mid-November and again in early to mid-January. The mean weight change for the sample was a gain of 1.64 lbs., with a standard deviation of the differences of 8.73 lbs. Find a 88% confidence level for the average weight gain.
Answers
Answer:
The 88% confidence level for the average weight gain if between -1.30 lbs and 4.58 lbs.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 23 - 1 = 22
88% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 22 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.88}{2} = 0.94[/tex]. So we have T = 1.6176
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.6176\frac{8.73}{\sqrt{23}} = 2.94[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 1.64 - 2.94 = -1.30 lbs
The upper end of the interval is the sample mean added to M. So it is 1.64 + 2.94 = 4.58 lbs
The 88% confidence level for the average weight gain if between -1.30 lbs and 4.58 lbs.
Answer: CANNOT DO
Step-by-step explanation:
The sample size is less than 30 and it does not specifically state that it is normally distributed, so you cannot compute the answer.
