In ΔOPQ, the measure of ∠Q=90°, the measure of ∠O=5°, and PQ = 4.6 feet. Find the length of QO to the nearest tenth of a foot.
Answers
Answer: [tex]\overline{QO} =[/tex] 53.68 ft
Explanation: Since ∠Q is 90°, ΔOPQ is a right triangle. So, there are hypotenuse, opposite side and adjacent side. And there the trigonometric relations: sine, cosine and tangent.
The image of the triangle is below.
Side [tex]\overline{PQ}[/tex] is opposite to the measure of ∠O and the length required is the adjacent side to the m∠O. According to the trigonometric relations:
[tex]tan\theta=\frac{opp}{adj}[/tex]
Substituing:
[tex]tan(5)=\frac{4.6}{\overline{QO}}[/tex]
Using a calculator, tan(5) = 0.0875:
[tex]\overline{QO}=\frac{4.6}{0.0875}[/tex]
[tex]\overline{QO}=53.68[/tex]
The length of [tex]\overline{QO}[/tex] to the nearest tenth of a foot is 53.68 feet.

what are the pros and cons of being a planetary geologist?
Answers
Answer:
Pros include lots of travel, more cool technology, and the sense that you're involved in a field with that could save a lot of lives. Cons are they're tough jobs to get, and if you don't get one your degree isn't broadly applicable to other careers. Probably a good job for an introvert, depending on your ambition.

Which technique is commonly practiced in the rain forest for clearing land for farming? a crop rotation and irrigation b slash and burn farming c terrace farming d ecotourism
Answers
Answer: the correct option is B( slash and burn farming).
Explanation:
The rain forest is dense and made up of many types of broad- leave trees that are mostly evergreen. The trees form three layers or strata. The treetops form a thick canopy that prevents sunlight from reaching the forest floor. As a result, the vegetation on the forest floor is sparse. Therefore, for farmers to achieve a successful crop yield, a practice for clearing land for farming known as slash and burn farming method is used.
The slash and burn method is used in rain forest where an area is selected and the vegetation is cut down and burnt. This is to obtain a field usually called swidden that can be used for farming. After slashing( cutting) down the vegetation, it is allowed to dry and burnt. This method makes the soil fertile only for a short period of time and as a result farmers are forced to allow the farmland to fallow to renew it's fertility. One major disadvantage about this method is that it takes a long period of time(5 -15 years) to allow the land regain its lost nutrients and this can grossly interrupt both the economic and financial benefits of a farmer.
Explain how the relative and absoulate age of rocks and the fossil record provide evidence of earths geological history?
Answers
To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. With absolute age dating, you get a real age in actual years.
The relative and the absolute age of rocks and fossil records provide evidence of the earths geographic history through the use of radiometric dating methods.
The dating methods that the geologists make use of are usually based on radioactive dating.
The natural decay of the elements or the compounds that are found in the objects are used as reliable sources of information to date the history of such happenings.

b. Using oil wealth to increase the standard of living in the United Arab Emirates
c. Iraq invading Kuwait to gain control of the oil fields in the Persian Gulf War
d. Kuwait trades oil for technology with the United States
Answers
Answer:
D. Kuwait trades oil for technology with the United States
Explanation:
This is the best answer since oil is a very useful commodity other countries will trade other resources like technology for it.
C. is incorrect because this isn't using oil as a strategic commodity. this is just using force to get what they want.
A. is incorrect because it clearly doesn't mention trading oil.
B. is incorrect because it's not using oil strategically. Trading oil for other resources that we need is strategic.
So that leaves D which is correct.

Which ponds will have a higher average oxygen concentration, ponds cooler than 20c or ponds hotter than 20c?
Answers
Answer:
ponds cooler than 20 °C
Explanation:
There is great effect of temperature on the dissolved oxygen in a pond water,
When the water is hotter it will hold less oxygen but when the water is cold it will holds more oxygen. Therefore, ponds cooler than 20 °C will will have a higher average oxygen concentration.
A musical concert is scheduled to start in Los Angeles in U.S.A longitude 120° west on Saturday by 4pm. At what time and day should Nigerians switch on their t.V. Sets to watch the concerts live. Longitude of Nigeria 15° east
Answers
Answer: 1 am on Sunday
Explanation:
Every distance of 15° longitude is an hour in time. This means that places that are 15° longitude apart have a time zone difference of an hour, areas that are 30° have a time zone difference of two hours and so on.
The time difference between a location in the U.S.A at longitude 120° west and Nigeria at 15° east would be:
= (120 + 15) / 15
= 9 hours
The 15 was added because Nigeria is east of the Greenwich meridian and the U.S. is west. The lines of longitude count down from the West to the East and get to zero at the Meridian. Then start again as they go east.
Areas east are also further in time than areas west so Nigeria is ahead of the U.S.
Nigeria is therefore ahead of that area by 9 hours. They would be able to watch the show at:
= 4pm + 9 hours
= 1 am on Sunday
