The environmental club is selling indoor herb gardens for $8 each for Earth Day. The goal is to raise at least $500 during the fundraiser. So far the club has raised $256 toward the goal. How many herb gardens must they sell in order to reach or exceed the $500 goal? Write and solve an inequality that models this situation, then enter the value the completes the statement "At least _______ herb gardens".
At least 16 more herb gardens must be sold in order to meet the fundraising goal
It is given that the environmental club is selling indoor herb gardens for $8 each for Earth Day.
The goal for the club is to raise at least $500 during the fundraiser.
So far the club has raised $256 toward the goal.
Let the number of herb gardens yet to be sold be 'x'
Thus total amount raised by 'x' herb garden sold= 8x
Thus, the equation for fundraising will be
8x+256=500
8x=500-256
8x=244
x= 244/8=31/2=15.5
Hence at least 16 more herb gardens must be sold in order to meet the fundraising goal

Main Answer :16
Concept and definitions should be there:
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value.
a ≠ b says that a is not equal to b
a < b says that a is less than b
a > b says that a is greater than b
(those two are known as strict inequality)
a ≤ b means that a is less than or equal to b
a ≥ b means that a is greater than or equal to b.
Given that:
It is given that the environmental club is selling indoor herb gardens for $8 each for Earth Day.
The goal for the club is to raise at least $500 during the fundraiser.
So far the club has raised $256 toward the goal.
Solving Part:
Let the number of herb gardens yet to be sold be 'x'
Thus total amount raised by 'x' herb garden sold= 8x
I can match an inequality to a situation it represents, solve it, and then explain what the solution means in the situation.
If I have a situation and an inequality that represents it, I can explain what the parts of the inequality mean in the situation.
We know that
$256≥ $500 → inequality that represent the situation
Thus, the equation for fundraising will be
8x+256=500
8x=500-256
8x=244
x= 244/8=31/2=15.5
Hence at least 16 more herb gardens must be sold in order to meet the fundraising goal.

The midpoint of segment EF is M(4, -1). Find endpoint F if the other endpoint E is at E(2, 3).
The x and y coordinates of the endpoint F are (6,-5)
The midpoint of a line segment is a point that is situated exactly at the middle from the two ends of the line segment
The coordinate of the mid-point or any other point can be found using the section formula.
For a point P with coordinates, the section formula is as follows: (x,y)
which divides the line segment A(x1,y1), B(x2,y2) in the ratio m:n, is given by the equation
Px=mx2+nx1/m+n Py=my2+ny1/m+n
Because the midpoint divides the line segment equally, m and n are both 1 in the midpoint case.
Thus the formula becomes
Px=1*x2+1*x1/1+1 Py = 1*y2+1*y1/1+1
where Px and Py are x and y co-ordinates of the point x and y
It is now assumed that midpoint M has coordinates (4,-1)
Point E is given by (2,3)
We are required to find F
Thus using section formula,
Mx=2+x/2 My=-3+y/2
4=2+x/2 -1=1+y/2
8-2=x -2-3=y
x=6 -5=y
Therefore, the coordinates of x and y of the endpoint F are(6,-5)

Chang wants to plant grass in his backyard. His backyard is in the shape of a rectangle. Its length is 32 feet and its width is 21 feet. Suppose each pack of seed covers 12 square feet. How many packs of seed will he need to cover the backyard?
Answer:
56 packs of seeds
Step-by-step explanation:
To find the area of Chang's backyard, we can use the formula for an area of a rectangle.
Area = length·width or A = lw
32·21 = 672 sq ft.
To find how many packets of seed he will need to cover the backyard, we can take the area of Chang's yard and divide it by how many square feet each pack of seed covers.
672/12 = 56
Chang will need 56 packs of seeds to cover the backyard.

Part of the proceeds from a garage sale was $330 worth of $5 and 520 bills. If there were 6 more $5 bills than $20 bills, find the number of each denomination.
The number of bills worth $20 is found to be 18 and the number of bills worth $5 is 12.
What is defined as the linear equation in two variables?A linear equation in two variables is one that is written in the form;
ax + by + c=0, where a, b, and c are real numbers and also the coefficients of x and y, i.e. a and b, are not equal to zero.
Now, as per the given question;
Let 'X' be the number of bills worth $20.
Let 'Y' be the number of bills worth $5.
Then, the total cost of the bills $330 is written as;
330 = 20X + 5Y
Now, if 6 more $5 bills is added to than $20 bills.
Y = X + 6, as there are 6 more $5 bills than $20 bills.
Substitute the value of Y in original equation.
330 = 20X + 5(X+6)
330 = 20X + 5X + 30
Further solving the equation.
300 = 25X
X = 300/25
X = 12 (number of bills worth $20)
Substitute the value in Y to find the number of bills worth $5.
Since, there are 6 more $5 bills than $20 bills, Y = 12+6 = 18
Thus, there are 18 number of bills worth $20.

if the pressure in the right tire is found to be 22 psi, what is the probability that the left tire has a pressure of at least 25 psi?
Considering the given probability distribution, we have that there is a 0.349 = 34.9% probability that the left tire has a pressure of at least 25 psi.
What is the probability distribution?The probability distribution for the air pressure of the tires of the car(X right, Y left) is given as follows:
f(x,y) = K(x² + y²), 18 ≤ x ≤ 28, 18 ≤ y ≤ 28.f(x,y) = 0, otherwise.The pressure in the right tire is found to be 22 psi, hence y = 22 and:
f(x,y) = K(x² + 484), 18 ≤ x ≤ 28.f(x,y) = 0, otherwise.The value of K is found considering that the sum of all probabilities has to be 1, hence:
[tex]\int_{18}^{28} K(x^2 + 484) dx = 1[/tex]
[tex]\frac{Kx^3}{3} + 484Kx\lbracket|_{x = 18}^{x = 28} = 1[/tex]
Applying the Fundamental Theorem of Calculus:
7317.33K + 13552K - 8712K - 1944K = 1
10213.33K = 1
K = 1/10213.33
K = 0.000098.
The probability that the left tire has a pressure of at least 25 psi is:
[tex]P(X \geq 25) = \int_{25}^{28} 0.000098(x^2 + 484) dx[/tex]
[tex]P(X \geq 25) = 0.000098\int_{25}^{28} (x^2 + 484) dx[/tex]
[tex]P(X \geq 25) = 0.000098\left(\frac{x^3}{3} + 484x\right)_{x = 25}^{x = 28}[/tex]
[tex]P(X \geq 25) = 0.000098(7317.33 + 13552 - 5208.33 - 12100)[/tex]

Answer:
The number of $5 bills is 6
The number of $1 bills is 8
Step-by-step explanation:
Given the number of $1 bills is x, and of $5 bills is y
Then x + y = 14 or x = 14 - y
And 1(x) + 5(y) = 38
then 1(14 - y) + 5y = 38
14 - y + 5y = 38
4y = 38 - 14
4y =24
y = 6
if the number of $5 bills is 6
then the number of $1 bills is 14 - 6 = 8

What is lateral and total surface area ?The only difference between lateral surface area and total surface area is in lateral surface area we only consider the side views and neglect the top and bottom on the other hand for total surface area we consider all sides.
As a sphere has no side it has only total surface area which is 4πr².
According to the given question Pedro uses cardboard to make a model of a square pyramid.
Also given that the edges of the of the model is 5 in. long and the height of the triangular face is 4 in.
As to make the base of the pyramid with is square we need to form a cube which has sides = height = 5 inches.
We know the total surface area of a cube is 6(side)² which is
= 6(5)² sq inches.
= 6(25) sq inches.
= 150 sq inches.
Now for the upper triangular part we need 4 triangles with height 4 inches and as the base of the cube is 5 inches therefore the base of the triangle will also be of 5 inches.
We know area of a triangles with given height and base is
= (1/2)×base×height.
So for four such triangles the area will be 4 times of this.
= 4[(1/2)×5×4] sq inches.
= 4[10] sq inches.
= 40 sq inches.
So, the total area of the square pyramid model will be (150 + 40) = 190 sq inches.
