Answer:
W(2W-19)
Step-by-step explanation:
let length = L
length= L feet
let Width= W
from the question,
twice the width = 2W
then L = 2W-19
the area of the rectangle
Area= length × width
Area= 2W-19×W
Area= 2W^2-19W
Area= W(2W-19)

the area of the triangle below is 1/4 square meters. what is the length of the base. express your answer in simplest form
Answer:
4/5
Step-by-step explanation:
Given,
Area of the triangle = 1/4 square meters
From the diagram,
Height = 2/5 m
To find : Length of the base
Formula : -
A = bh/2
Here,
A denotes Area
b denotes Base
h denotes Height
A = 1/4
h = 2/5
A = bh/2
Cross multiply,
A * 2 = bh
2A = bh
2 * (1/4) = b * (2/5)
(1 * 2)/4 = (b * 2)/5
2/4 = 2b/5
1/2 = 2b/5
Cross multiply,
1 * 5 = 2 * 2b
5 = 4b
b = 4/5 meters
Hence,
The length of the base is 4/5 meters.
The length of the base of the triangle is 5/4 meters.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
The formula to find the area of the triangle is,
Area = [tex]\frac{1}{2}[/tex] × base × height
Given,
Area of the given triangle = 1/4 square meters
Height = 2/5 meters
Substituting in to the formula,
[tex]\frac{1}{2}[/tex] × base × 2/5 = 1/4
1/5 × base = 1/4
Base = 5/4 meters
Hence the base of the triangle is 5/4 meters.

Starting with blue balls, in each of sequential rounds, we remove a random ball and replace it with a new red ball. for example, after the first round we have 9 blue balls and one red ball, after the second round, with probability we have 8 blue balls and 2 red balls, and with probability we have 9 blue balls and one red ball, etc. what is the probability that the ball we remove at the 11th round is blue
The probability that the ball we remove at the 11th round is blue will be 0.6.
How to calculate probability?From the information given, we remove a random ball and replace it with a new red ball. for example, after the first round we have 9 blue balls and one red ball.
Since we have 9 blue balls and remove one every round. Let's assume that the number of blue and red balls will be 6 and 4 respectively in the 11 the round
Therefore, the probability that the ball we remove at the 11th round is blue will be:
= 6/(6 + 4)

Answer:
(a)no mode
(b)mean= 4
(c)median= 4
Step-by-step explanation:
the measure of centre are the mode, mean and median
mode: this is the heighest occuring number or the number with the heighest frequency.
mean: this is the average number. it's obtained by adding the data values in a set of numbers and dividing the sum by the number of data items.
meadian: this is the middle number when the data is ordered or when the data is arranged in ascending or descending order.
from the data,
mode: no number occured more than the other. therefore, there is no mode
mean = 1+2+3+4+5+6+7 = 28/7= 4
median= 1,2,3,4,5,6,7
the middle numbers is 4

Use the parabola tool to graph the quadratic function.
f(x)=3x^2+6x−24
Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.
Answer:
See below
Step-by-step explanation:
[tex]f(x)=3x^2+6x-24\\\\f(x)=3(x^2+2x-8)\\\\f(x)+3(9)=3(x^2+2x-8+9)\\\\f(x)+27=3(x^2+2x+1)\\\\f(x)=3(x+1)^2-27[/tex]
Here, we can see that the vertex of the parabola is [tex](-1,-27)[/tex] when we compare to the equation [tex]y=(x-h)^2+k[/tex] with vertex [tex](h,k)[/tex].
A second point you could plot is the y-intercept, when [tex]x=0[/tex]:
[tex]f(0)=3(0+1)^2-27\\\\f(0)=3-27\\\\f(0)=-24[/tex]
So, your y-intercept is [tex](0,-24)[/tex].
Solve the inequality for x and identify the graph of its solution (picture added)
The inequality that is correctly graphed is the one in option B.
Which graph correctly describes the inequality?Remember that if we have symbols like ≤ or ≥, we graph a solid circle, while if we use symbols like > or <, we need to use an open circle.
If we write:
x < -3
Then we must have an orange line to the left of x < -3
Finally, the option that you marked is wrong.
Why?
There it says that:
"x < -3 and x > 1"
The "and" means that x meets both properties at the same time, which is impossible.
The correct option is the one that says:
"x < -3 or x > 1".
The "or" means that x needs to meet only one of the two conditions, not both at the same time.

Despite control measures, the pigeon population in Winchester is increasing by 10% each year. If there are currently 9,520 pigeons, how many pigeons will there be in 13 years?
If necessary, round your answer to the nearest whole number.
Using an exponential function, it is found that there will be 32,866 pigeons in 13 years.

In which:
A(0) is the initial value.r is the decay rate, as a decimal.The initial value and the growth rate are given by:
A(0) = 9520, r = 0.1.

Francine has a picture with a length its width. She wants to enlarge the picture to have an area of 375 in2. What will the dimensions of the enlarged picture be? Model the scenario and solve. Then, explain in at least one sentence your solution and include the reasonableness of your solution.
Answer:
25 in x 15 in
Step-by-step explanation:
Given:
Length = 3/5 the widthArea = 375 in²Let width = [tex]x[/tex]
Therefore, length = 3/5 [tex]x[/tex]
First create an equation for the area of the picture based on the given information for its width and length:
[tex]\begin{aligned} \implies \textsf{Area of original picture} & = \sf width \times length\\& = x\left(\dfrac{3}{5}x\right)\\& = \dfrac{3}{5}x^2\end{aligned}[/tex]
We are told the area of the enlarged picture is 375 in². Therefore, substitute this into the equation and solve for [tex]x[/tex] to find the width of the enlarged picture:
[tex]\begin{aligned}\textsf{Area} & = 375\\ \implies \dfrac{3}{5}x^2 & = 375\\ x^2 & =375 \cdot \dfrac{5}{3}\\ x^2 & =625\\ x & = \sqrt{625}\\ x& = 25\end{aligned}[/tex]
Therefore, the width of the enlarged picture is 25 in.
Substitute the found value of [tex]x[/tex] into the expression for length to find the length of the enlarged picture:
[tex]\begin{aligned}\sf Length & = \dfrac{3}{5}x\\\\\implies \sf Length & = \dfrac{3}{5}(25)\\\\& = 15\: \sf in\end{aligned}[/tex]
Therefore, the dimensions of the enlarged picture are 25 in x 15 in. The width is 25 in and the length is 15 in, as the length is 3/5 of the width.
