Answer: 68,819 rabbits
Step-by-step explanation:
First find the annual rate of growth that took the number of rabbits from 9,400 in 1998 to 32,000 in 2006.
Use the future value formula:
Number of years = 2006 - 1998 = 8 years
Future value formula:
Future value = Current value * ( 1 + rate) ^ number of years
Assume 2006 is the future and 1998 is present.
32,000 = 9,400 * (1 + r) ⁸
32,000 / 9,400 = (1 + r)⁸
(1 + r)⁸ = 3.404255319
1 + r = ⁸√3.404255319
r = ⁸√3.404255319 - 1
r = 16.55%
Use that rate to find the number of rabbits in 2011:
= Current value * (1 + rate) ^ number of years
Number of years = 2011 - 2006 = 5 years
= 32,000 * ( 1 + 16.55%)⁵
= 68,819 rabbits

Our school is selling t-shirts and sweatshirts as a fundraiser . One student buys 2 t-shirts and 2 sweatshirts for $26 . Another student buys 1 t-shirt and 3 sweatshirts for $33 . This situation can be modeled by the system of equations below .
Answer:
The value of each T-shirt is $ 3 and the value of each sweatshirt is $ 10.
Step-by-step explanation:
Given that our school is selling T-shirts and sweatshirts as a fundraiser, and one student buys 2 Tt-shirts and 2 sweatshirts for $ 26, while another student buys 1 T-shirt and 3 sweatshirts for $ 33, to determine the value of the T-shirts and sweatshirts the following calculation must be made:
2X + 2Y = 26
X + 3Y = 33
Y - X = 7
2 x 3 + 2 x 10 = X
6 + 20 = X
26 = X
Therefore, the value of each T-shirt is $ 3 and the value of each sweatshirt is $ 10.

Martha has two jobs. One pays $15 per hour, and she works at that job 10 hours per week. The other job pays $13 per hour, and she works at that job 30 hours per week. How much money does she make per year?
.
Answer:
$28080 per year
Step-by-step explanation:
15$ per hour for the first job and she does it for 10 hours each week, this means, 15*10 which is 150. So we have 150 for the 1st job every week.
2nd job, 13$ per hour. She does that for 30 hours a week so we have 13*30 which is 390$ per week.
The two jobs together are 150 per week and 390 per week which means 540$ per week. Now` if we want to find how much she makes in a year, the are 52 weeks in a year, so multiply 540$ *52=$28080
So she makes $28080 per year

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB=3 and AD=1, what is the length of AC?
========================================================
Explanation:
For now, focus on triangle ABD. This is a right triangle due to BD being an altitude.
Use the pythagorean theorem to find that...
(AD)^2 + (BD)^2 = (AB)^2
(1)^2 + (BD)^2 = (3)^2
1 + (BD)^2 = 9
(BD)^2 = 9-1
(BD)^2 = 8
Normally we would isolate BD itself, but I'll stop short and use that last line instead.
------------------
The triangles ABD and BCD are similar triangles (we can prove this using the AA similarity theorem).
Since we have similar triangles, we can form the proportion shown below
AD/BD = BD/CD
This cross multiplies to
AD*CD = (BD)^2
We know that AD = 1 and (BD)^2 = 8, so,
AD*CD = (BD)^2
1*CD = 8
CD = 8
This then means,
x = CD+DA
x = 8+1
x = 9
AC is 9 units long.

find the height of a right cylinder with surface area 160pie square units and radius 5 units
Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder = [tex]160\pi[/tex]
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:
[tex]A=2\pi rh+2\pi r^2[/tex]
Where, r is radius and h is the height of the cylinder.
Putting [tex]r=5, A=160\pi[/tex] in the above formula, we get
[tex]160\pi =2\pi (5)(h)+2\pi (5)^2[/tex]
[tex]160\pi =10\pi h+2\pi (25)[/tex]
[tex]160\pi =10\pi h+50\pi [/tex]
Subtract [tex]50\pi[/tex] from both sides.
[tex]160\pi -50\pi=10\pi h [/tex]
[tex]110\pi=10\pi h [/tex]
Divide both sides by [tex]10\pi[/tex].
[tex]\dfrac{110\pi}{10\pi}=h[/tex]
[tex]11=h[/tex]
Therefore, the height of the cylinder is 11 units.

Step-by-step explanation:
Determine the area of a parallelogram if
its base is 16 cm and its height is 7 cm.
=====================================
Work Shown:
area = base*height
area = 16*7
area = 112 square cm
----------------
Extra info (optional section):
The area formula for a parallelogram is the same as the formula for a rectangle. Imagine tilting a rectangle so that it's slanted. The area has not changed.
Or another thing to imagine is that let's say we had a stack of 2 by 4s. If the stack is perfectly vertical, aka forming a rectangle, then we can nudge the beams so that we can form a slanted parallelogram instead. Both configurations involve the same amount of wood, and therefore would lead to the same frontal surface area.
1) Find 5 points on the line y = 3/5 x - 4 by picking 5 x values, plugging in, and getting 5 y values. You must pick x
values that result in INTEGER values for y. Show every step of the process, working vertically.
2) Graph the line from problem 1. You must use a straightedge on axes and line. Each line on the graph paper is one
unit. Put arrowheads on the line. Do NOT put numbers or hash marks on your graph. Show your 5 points clearly
3) Using the formula and working vertically, firid the slope between the points (-2,5) and (6,-7).
4) Identify the slope and y-intercept of the line y = -4/3 x + 4
5) Graph the line from problem #4 by plotting the y-intercept, and then using the slope to get a second point. All rules
from problem 2 apply here as well.

Answer:
[tex]482.5\:\mathrm{in^2}[/tex]
Step-by-step explanation:
The area of the figure consists of a rectangle with a triangle removed from the corner of it. Therefore, the area of the composite of the figure can be found by subtracting the area of the triangle from the area of the rectangle.
Area of the rectangle: [tex]25\cdot 20=500\:\mathrm{in^2}[/tex]
Area of the triangle: [tex]\frac{1}{2}\cdot 5\cdot 7=17.5\:\mathrm{in^2}[/tex]
Thus, the area of the figure is [tex]500-17.5=\boxed{482.5\:\mathrm{in^2}}[/tex]

Hey can someone help me with these I will give a lot of points and brainliest!!!
Answer:
6) 62.5%
7) 54
8) B
Step-by-step explanation:
For number 6, just add 96 and 160 and then do 160/(96+160), which is equal to 0. 625, or 62.5%.
for number 7, x is always equal to 1/3 of y, so if x is 18, we know that 18 is 1/3 of y. 18x3 is equal to 54, which is your answer.
For number 8, you can see that B is right because it uses the greatest common factor of 32 and 48, which is 16. All the other answers can be simplified more.
Answer:
6. C) 62.5%
7. D) 54
8. B) 16(2c + 3d)
Step-by-step explanation:
160 + 96 = 256
[tex]\frac{160}{256}=\frac{160/32}{256/32}=\frac{5}{8}[/tex]
5 ÷ 8 = 0.625
0.625 × 100
62.5%
GCF = 32
The factors of 160: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
The factors of 256: 1, 2, 4, 8, 16, 32, 64, 128, 256
The GCF is 32.
1:3 = 7:21 = 9:27 = 13:39 = 18:y
[tex]\frac{1}{3}: \frac{18}{y}[/tex]
1 × y = 18 × 3
y = 54
GCF(32, 48)
32 = 2 × 2 × 2 × 2 × 2
48 = 2 × 2 × 2 × 2 × 3
GCF = 2 × 2 × 2 × 2
GCF = 16

x^2+7x+6
Step-by-step explanation:
The length of a rectangular plot is 9/2 times that of it's breadth. If the area of the plot is 200
square meters, then what is it's length?
Answer:
The length of the rectangular plot is 30 m
Step-by-step explanation:
Mathematically, the area of a rectangle is the product of its length and width
Let us have the length as x m ; for the length to be 9/2 of the breadth, it means the breadth is 2/9 of the length
so we have the breadth as 2/9 * x = 2x/9
The product of the two equals the area which is 200 square meters
thus, we have it that;
x * 2x/9 = 200
2x^2 = 9 * 200
x^2 = 1800/2
x^2 = 900
x = √900
x = 30 m
Substitute the given side lengths into the equation for the Pythagorean Theorem.

Write an explicit formula for a_n, the nth term of the sequence 4, -20, 100, ...
Answer:
[tex]a_{n}[/tex] = 4 [tex](-5)^{n-1}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms , that is
r = - 20 ÷ 4 = 100 ÷ - 20 = - 5
This indicates the sequence is geometric with nth term ( explicit formula )
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 4 and r = - 5 , then
[tex]a_{n}[/tex] = 4 [tex](-5)^{n-1}[/tex]
