One species of fish in a fishery had an initial population of 255 fish and grew by 25 fish each season. A second species that was being overfished started with an initial population of 450 fish, and then decreased by 40 fish each season. Assuming a linear change, write equations for the populations of each species. When will the two populations have the same amount of fish? After how many seasons will the second species be eliminated?
Answer:
they intersect at 3.5 seasons, 312 fish. the second gets elimed at 11 seasons
Step-by-step explanation:
equations:
first:
amount of fish = 225 + 25*season
second:
amount of fish = 450 - 40*season

Convert 2 inches into centimeters. Round your answer to the nearest tenth.
Please answer quick if you get it right I will mark you a Brainliest
Answer:
5.1
Step-by-step explanation:
multiply the length value by 2.54
2x2.54=5.08, which rounds to 5.1
if the given length is 2 inches. The obtained length in the centimeter will be 5.1 cm to the nearest tenth.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
It is given that, the length is 2 inches.
We have to convert the given length is in centimeters,
As we know,1 inch consists of 2.54 cm.
1 inches = 2.54 cm
So for 2 inches, we have to multiply the obtained data by 2 as,
2 inches = 2.54 × 2
2 inches = 5.08 cm
The obtained value to the nearest tenth will be 5.1 cm.
Thus, if the given length is 2 inches. The obtained length in the centimeter will be 5.1 cm to the nearest tenth.

1. Howard's CD House sells new CDs for $15 each and used CDs for $6 each. Bre'anna bought 51 CDs and spent a
total of $576 on the CDs. If n represents the number of new CDs, and u represents the number of used CDs, how
many of each type of CD did she buy?
The numbers of new CDs is 30 and the old CDs is 21.
To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.
System of EquationsThis is used to solve a series or complex of word problems in which we can represent in a mathematical statements;
Let n represents numbers of new CDsLet u represents numbers of old CDsThe equations can be represented as
[tex]n + u = 51 ...equation(i)\\15n + 6u = 576 ... equation(ii)[/tex]
Let's take equation (i)
Making n the subject of formula
[tex]n + u = 51\\n = 51 - u...equation(iii)[/tex]
we can put equation (iii) into equation (ii)
[tex]15n + 6u =576\\n = 51 - u\\15(51 - u) + 6u = 576\\765-15u + 6u = 576\\collect like terms\\765-576=15u - 6u\\189=9u\\9u/9 = 189/9\\u = 21[/tex]
Let's put the value of u into equation (i)
[tex]n + u = 51\\u = 21\\n + 21 = 51\\n = 51 - 21\\n = 30[/tex]
From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.

simultaneous equations find x and y
2x/ y + y/ x =3
3x-y=2
Answer:
x = 1 and y = 1
Step-by-step explanation:
2x/y + y/x = 3
3x - y = 2
we first of all get the simple equation from the two equations and in this case we will use substitution method
3x - y = 2
then we make y the subject of the formula
y = 3x - 2
let's use y on the top equation to substitute
2x/y + y/x = 3
2x/3x - 2 + 3x - 2/x
like terms cancel
thus:
2x/1 + 1/x = 3
3x -2x = 1
x = 1
ANDAND since we have x, we still use substitution method to find y
3x - 2 = y
3 (1) - 2 = y
3 - 2 = y
y = 1

Arun bought a pair of skates at the sale where the discount given was 20%. If the amount he pays is 1600 find the marked price
Answer:
2000
Step-by-step explanation:
1600 is 100% - 20% = 80% of the original price.
So it is 4/5 of the original price.
So, the marked price is 1600 * 5/4 = 2000

we looking for distance
Answer:
240 m
Step-by-step explanation:
Figure is attached.
The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min. The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).
What's the area under the graph?
The red outline forms a trapezoid. The area of a trapezoid is [tex]A=\frac{1}{2}h(b_1+b_2)[/tex] where the b's are the lengths of the two parallel base and h is the height (the distance between the bases).
Reading the graph carefully (notice the scales!)...
[tex]A=\frac{1}{2}(4)(30+90)=(2)(120)=240 \text{m}[/tex]

A bag contains 7 green marbles,2 white marble s, 5 orange marbles,9 blue marbles, and 7 red marbles. a marble will be drawn from the bag and replaced 180 times what is a reasonable prediction for the number of times a white or red marble will be drawn?
The reasonable probability that a white or red marble will be drawn all 180 times is; (3/10)¹⁸⁰.
Probability with replacementSince the probability is with replacement;
First, the total number of marbles in the bag is; 7+2+9+5+7 = 30.Hence, the probability that a white or red ball is drawn each time is; 2+7 = 9 possible outcomes.
Hence, it follows that the probability for white or red each time is; 9/30 = 3/10
Hence, when drawn 180 times, the probability is;
P = (3/10)¹⁸⁰.Read more on probability;
