A city’s population is 12,800. It is predicted that the population will increase by 3% each year.
Part a: Write a function that can be used to find the city’s population after t years.
Part b: If the city’s population, p, continues to grow 3% per year, what will the approximate population be in 15 years. Round to the nearest integer.
Answer:
18,560
Step-by-step explanation:
3 percent *12800 =
(3:100)*12800 =
(3*12800):100 =
38400:100 = 384
384*15 = 5760
12800 + 5760 = 18560
there 8 books in a series. the number of pages in each book are: 173, 205, 195, 215, 219, 184, 211, and 400.
Which measure of center best describes the typical number of pages in the books in this series? a. mean b. median
What is the value of measure of center that best describes the typical number of pages in the books in this series?
Answer:225.25 or Mean
Step-by-step explanation: Put the sequence of numbers in order: 173,184,195,205,211,215,219,400
Cross of the end number each side until you have only 2 numbers:205,211
Add these numbers then divide them by 2: 205+211=416 416\2= 208
208 is the median
To find the mean is all of the numbers added together divided by the number of numbers: 173+205+195+215+219+184+211+400=1,802/8+225.25
Now compare the median:208 and the mean:225.25 to the sequence of numbers and see which one best describes the typical number of pages in the books. To do that you can subtract 173 from 400: 227
So the answer that's closest to 227 is 225.25.
I think anyway.
The mean and median of the given observation are 225.25 and 208 respectively and the value of the measure of the center would be 227 that best describes the typical number of pages in the books in this series.
What is arithmetic mean?Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the set of observations as :
173, 205, 195, 215, 219, 184, 211, and 400
Arrange the data in ascending order.
173, 184, 195, 205, 211, 215, 219, 400
Here n = 8 which is an even number
For finding the median we have to calculate the average of 205 and 211
Thus, the median is 208
When all the numbers are added up and divided by the total number of numbers, the mean is obtained:
⇒ 173 + 205 + 195 + 215 + 219 + 184 + 211 + 400
⇒ 1,802
⇒ mean = 1,802/8
⇒ mean = 225.25
In order to determine which figure accurately represents the median value of 208 to the mean value of 225.25.
To achieve it, divide 400 by 173, which equals 227.
Therefore, 225.25 is the answer that is closest to 227.
Hence, the mean and median of the given observation are 225.25 and 208 respectively and the value of the measure of the center would be 227 that best describes the typical number of pages in the books in this series.

Subtract 5 from 20 to get 15.
3x=15
Divide both sides by 3.
x= 15/3
Divide 15 by 3 to get 5.

First, complete the sentence to show how the figure can be decomposed into triangles and rectangles with the fewest number of pieces.
Then find the area of the divisions.
The figure can be divided into a triangle and a rectangle.
The area of a triangle is 10 sq inches.
The area of a rectangle is 80 sq inches.
The total area of the figure is 90 sq inches.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
The figure can be divided into a triangle and a rectangle.
The height of the triangle is 2 inches and the base is 10 inches.
We know the area of a triangle is (1/2)×base×heiht.
∴ Area = (1/2)×10×2 sq inches.
Area = 10 sq inches.
We know the area of a rectangle is length×width.
∴ Area = (10×8) sq inches.
Area = 80 sq inches.
The total area of the figure is (10 + 80) sq inches = 90 sq inches.

Graph a rectangle with an area of 12 square units. State the lengths of each of the sides. Write your answer LxW (length of one side X length of the other side) please help
A rectangle with area of 12 square units would have sides of length 4 units and 3 units. Area would therefore be 4 x 5.
What are the side lengths of this rectangle?A rectangle must be such that one side is longer than the other side.
The area of a rectangle is found as:
= Length x Width
As the area is 12, the length and width have to be numbers that when multiplied, will give you 12.
The factors of 12 which allow this to happen are:

What is the area of the patio if the yard is 12 feet on each side?
How do I do this?
144 feet squared
Step-by-step explanation:Squares are 4 sided shapes that have an equal length on each side.
Area Formula
The area of a square (or rectangle) is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width. Due to the fact that squares have four equal sides, the formula can be rewritten as [tex]l^2[/tex].
Solving For Area
Plug the length value into the formula.
[tex]12^2=144[/tex]Then, add the units to the answer. Because the length is multiplied by itself and the original unit is feet, the units are feet squared.

Volume?
Answer: i'm pretty sure the base is 14cm, the height is 7cm, and the volume is 49 cm2
Step-by-step explanation:
for the base, i just added up 6cm and 8cm to get 14cm, the height was already 7cm, and for the volume, its (b*h)/2, since its a triangular 3d object, so (7*14)/2=49cm2
base=?
height=7
volume=?
Answer:
The area of the base is 24 [tex]cm^{2}[/tex]
The volume is 168 [tex]cm^{3}[/tex]
Step-by-step explanation:
The area of the base is found by solving [tex]0.5*6*8[/tex], because that is the formula for the area of a triangle.
The volume is found by multiplying the area of the base by the height: [tex]24*7=168[/tex]
I know the measure of angle m is 100 degrees. I did this multiple times and J and L are not 80 degrees so what are the measures of angles L and J?
Answer:
[tex]m\angle L = 100^{\circ}[/tex].
[tex]m\angle J = 80^{\circ}[/tex].
[tex]m\angle M = 100^{\circ}[/tex].
Step-by-step explanation:
Since segment [tex]JM[/tex] is parallel to segment [tex]KL[/tex], quadrilateral [tex]JKLM[/tex] is a trapezoid.
Segment [tex]JK[/tex] and segment [tex]LM[/tex] (the two legs of this trapezoid) are equal in length. Hence, trapezoid [tex]JKLM[/tex] would be an isoscele trapezoid. By symmetry, [tex]m\angle L = m \angle K = 100^{\circ}[/tex].
Line [tex]JK[/tex] traverses line [tex]JM[/tex] and line [tex]KL[/tex]. [tex]\angle J[/tex] and [tex]\angle K[/tex] are a pair of consecutive interior angles as they are both between [tex]JM\![/tex] and [tex]KL\![/tex] and are on the same side of the traversal, [tex]JK\![/tex].
Since line [tex]JM[/tex] is parallel to line [tex]KL[/tex], any pair of consecutive interior angles between these two lines would add up to [tex]180^{\circ}[/tex] (supplementary angles.) Thus, [tex]\angle J[/tex] and [tex]\angle K[/tex] are supplementary angles; [tex]m\angle J + m\angle K = 180^{\circ}[/tex].
Since [tex]m\angle K = 100^{\circ}[/tex], [tex]m\angle J = 180^{\circ} - m\angle K = 180^{\circ} - 100^{\circ} = 80^{\circ}[/tex].
