How many circles, each with a 4-inch radius, can be cut from a rectangular sheet ofpaper, measuring 16 inches x 24 inches?
(A) 6
(B) 7
(C) 8
(D) 12
(E) 24

Answers

Answer 1
Answer: A)6 
the radius is mentioned at four, meaning the length is 8
16/8=2 
24/8=3 
2*3=6 
Answer 2
Answer: Let us find the area of circle first

Area of circle = pi x r x r

= 3.14 x 4 x 4
= 50.24

Area of Rectangular sheet = 16 x 24
= 384

Thus, no. of circles = area of recatngle / area of circle

= 384 / 50.24

= 4.64

Thus, the answer is (A) , because it is the nearest.

Which type of biome is characterized by the following descriptions? moderate temperatures with seasonal changes very high amounts of rainfall thick canopy of trees which filters out a majority of the suns rays, leaving the forest floor mostly shaded. broadleaf or coniferous trees

Answers

The answer is Tropical Rainforest Biome

The tropical rainforest has a moderate temperature with seasonal changes. The amount of rainfall in a tropical rainforest is high. It has a thick canopy of trees which filters out a majority of the sunlight which is why the forest floor is almost shaded. 

It's temperate rainforests...................................................

Contrast the frequency and wavelength of gamma rays with the frequencies and wavelengths of other waves on the electromagnetic spectrum

Answers

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, along  electromagnetic spectrum, wavelength increases, frequency decreases.

What is electromagnetic wave?

Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.

There is a relation between energy of wave. frequency of wave, and wavelength of wave

Mathematically,

E=hc/λ

where,

E = energy of electromagnetic wave

h is planks constant having value 6.67×10⁻³⁴js

c is speed of light that is 3×10⁸m/s

λ is the wavelength of electromagnetic wave

Wavelength is inversely proportional to frequency of wave. From left to right in electromagnetic spectrum, wavelength increases.

Therefore, along  electromagnetic spectrum, wavelength increases, frequency decreases.

What kind of data are these marine biologists and charter trips looking for in terms of the research being done on sharks?

Answers

Answer: Please see answer below

Explanation: The type of data marine biologists and charter trips look for in terms of the research being done on sharks include Shark's habitat, feeding, movement, reproduction, anatomy, communication, evolution and social structure but the most common data being sought is the data on Shark attack.

Today, it is easy for researchers to get many data from sharks by tagging the sharks to record data points.The mostly used tags include

Acoustic tag and Satellite tags others include radio tags etc.

Why does the oxidation of organic compounds by molecular oxygen to produce CO₂ and water release free energy? A) The covalent bonds in organic molecules and molecular oxygen have more kinetic energy than the covalent bonds in water and carbon dioxide. B) Electrons are being moved from atoms that have a lower affinity for electrons (such as C) to atoms with a higher affinity for electrons (such as O). C) The oxidation of organic compounds can be used to make ATP. D) The electrons have a higher potential energy when associated with water and CO₂ than they do in organic compounds. E) The covalent bond in O₂ is unstable and easily broken by electrons from organic molecules.
