Assuming that the traps stay the same, we know that the number of moths they catch will be relative to the size of the population of moths. From this, we can see that the trend in the population of light moths is a steady decrease from year to year, and the trend in the population of the dark moths is a steady increase over the same time period.

Since the trees have been darkened by industrial pollution (they have black smoke on them), we know that the dark moths camouflage better than the light moths. Because of this, the white moths get eaten by predators more often and their population goes down gradually; the dark moths, however, camouflage easily, and their population goes up since they get eaten less often.

If the environment were cleaned up, the light moths' population would increase (since they camouflage better on clean trees), while the dark moths' population would decrease (since they camouflage better on dirty, polluted trees).

How does the volume of a prism change if each dimension of the prism is doubled?

Answers

The prism has 3 dimensions. So, if you double the linear sizes ("dimensions") the volume is multiplied by 2^3=8.
Correct!

V = A*h;
A ---> (2*2)A;
h ---> 2h;

V ---> (2*2*2)V = 8V.

A drawer has some red, green, and blue marbles. There are 33 marbles.There are 4 times as many red marbles as green marbles. There are half
as many blue marbles as green marbles. How many blue marbles are in
the drawer?

Answers

Green marbles = x.
There are 4 times as many red marbles as green marbles, so red marbles = 4x.
There are half as many blue marbles as green marbles, so blue marbles = 0.5x
There are 33 marbles in total, so x+4x+0.5x=33.

x+4x+0.5x=33 \n 5.5x=33 \n x=(33)/(5.5)=(330)/(55)=(30 * 11)/(5 * 11)=(30)/(5)=6 \n \n0.5x=0.5 * 6=3

There are 3 blue marbles.
so number of red is represented by r
number of green is represented by g
number of blue is represented by b

so r+g+b=33

there are 4 times as many red as green or
r=4g
there are half as many blue as green
1/2g=b or g=2b

so r+g+b=33
we can subsitute 1/2g=b for b
r+g+1/2g=33
subsitute r=4g for r in the equation
4g+g+1/2g=33
add like terms
5 1/2g=33
multiply both sides by 2
11g=66
divide both sides by 11
g=6

there are 6 green marbles

subsitute g=6 into r=4g and g=2b

r=4(6)
r=24
there are 24 red marbles

g=2b
6=2b
divide both sides by 2
3=b
threre are 3 blue marbles



there are 24 red marbles, 6 green marbles, and 3 blue marbles and 24+6+3=33
r=24
g=6
b=3

Neil had some olive oil.  He used 1/5 liter to make a salad dressing.  There was 1/2 liter of olive oil remaining in the bottle. What amount of olive oil did Neil have in the bottle before using some for the salad dressing and the steps to calculate it?

Answers

First you have to put the fractions in the same denominator. 1/5 and 1/2, times the denominators together and get 10. To get 5 to 10 you have to times by 2 so you do the same to the top (2/10) and to get 2 to 10 you times by 5 (5/10). So to start he had 7/10 of olive oil.
1/5 + 1/2. Make sure the under number are same. Become 2/10 + 5/10 = 7/10

A builder has bought a plot of land on which he will build a house. The plot is a rectangle with an area of 50,000 square feet. The following coordinates have been marked on a coordinate plane by the builder; (60, 60), (60, 110), and (160, 110). What is the coordinate of the fourth vertex of the rectangle plot?

Answers

The answer (160, 60) because my sister taught me if it is a square or a rectangle like the coordinates that you gave me, take out the numbers that are the same and in the same area as the number is. 
160,60 s the 4th vertex

Jacob wants to make a graph to show the relationship between temperatures in Fahrenheit and degrees Celsius. He plots the following points:(11, −11.7), (15, −9.4), (25, −3.9), (35, 1.7), (45, 7.2) He uses the following steps to plot the graph: 1.Label origin as (0, 0) 2.On x-axis, label Temperature in Fahrenheit. 3.On y-axis, label Temperature in degrees Celsius. 4.The scale on x-axis starts from 0 and goes up to 700 at intervals of 20. 5.The scale on the y-axis starts from −12 and goes up to 12 at intervals of 2. Which of the following best describes the graph? A. It will not be spread out horizontally across the entire coordinate plane because in Step 4, Jacob selected an incorrect scale on the x-axis. B. It will not be spread out vertically across the entire coordinate plane because in Step 5, Jacob selected an incorrect scale on the y-axis. C. It will not be spread out horizontally across the entire coordinate plane because in Step 2, Jacob plotted Fahrenheit instead of Celsius on the x-axis. D. It will not be spread out vertically across the entire coordinate plane because in Step 3, Jacob plotted Celsius instead of Fahrenheit on the y-axis.
