Two rabbits land on deserted Salt Island; they breed,and the number of rabbits on the island doubles every 4 weeks. Two other rabbits arrive on deserted Pepper Island; these rabbits triple every 4 weeks. At the end of the 12 weeks, one python arrives on each island. As each python grows, the number of rabbits it can eat each week doubles. The first week, each eats 1 rabbit, the second week, 2, and so forth. How long will it take the python to wipe out the rabbits on each island?

Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.

In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6

2 In eln2x - In eln 10x = In 30
X = 30
X= 75
X = 150
X=300
Answer:
x = 75 hope this helped
Step-by-step explanation:
The true solution to the equation is,
⇒ x = 75
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
Now, We can simply as;
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
⇒ 2 ln 2x - ln 10x = ln 30
⇒ ln (2x)² - ln 10x = ln 30
⇒ ln (2x)² / 10x = ln 30
⇒ 4x² / 10x = 30
⇒ 4x = 300
⇒ x = 75
Thus, The true solution to the equation is,
⇒ x = 75

what is the volume.
(pls hurry cause i have to turn in soon.)
which three statements are true about the line segment CB
it's the radius of the circle
it is the circumference of the circle
it is a cord
it is 6cm long
it is diameter of the circle
it is 7cm long
it is 1.75cm long
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45

how do i solve? the help video doesnt actually help
Answer:
y = 5x - 8
Step-by-step explanation:
The linear equation in slope intercept form :
y = mx + c
m = slope ; c = intercept
m = Rise / Run = (y2 - y1) / (x2 - x 1)
Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20
Run = (x2 - x1) = (4 - 0) = 4
Slope, m = Rise / Run = 20 /4 = 5
Hence,
y = 5x + c
For the points ; y = 12 ; x = 4 ; we could obtain c
12 = 5(4) + c
12 = 20 + c
12 - 20 = c
-8 = c
The equation becomes :
y = 5x - 8
Kade has $45 in savings and wants to purchase a video game console for $250. He has a coupon for 10% off, and sales tax is 8.25%. In order to be financially responsible, Kade wants to wait until he has enough in savings to not have to borrow money. If Kade is able to save $45 each week, what is the minimum number of weeks Kade should save before making his purchase?
Answer:
5 weeks
Step-by-step explanation:
First, solve for the total cost of the game console after tax and a coupon
Solve for tax:
$250 × 8.25%
Convert percentage into a decimal
250 × 0.0825
20.625
Round up to nearest hundredths place (because the unit is dollars)
20.63
Add this tax onto the original cost
250 + 20.63
270.63
Subtract the coupon from the total
270.63 - 10
260.63
Total cost is $260.63
Now let's find how much Kade needs to save so set up an equation
Variable x = number of weeks
45 + 45x = 260.63
Subtract 45 from both sides to isolate the variable
45x = 215.63
Divide both sides by 45
x = 4.791777...
Round up to nearest whole number (because units are weeks)
x = 5 weeks
