Which of these sequences shows the flow of energy from the sun through organisms on Earth?
1 sun → producer → consumer → decomposer
2 sun → consumer-producer → decomposer
Answer:
I'm pretty sure it's number 1. The sun goes to plants and the plants get consumed. I don't think that the consumer eats the sun... just kidding. But yeah it's the first one.
1 sun → producer → consumer → decomposer
The art club is designing a rectangular mural for the school hallway. Three corners are located at (-1, -1), (-1, 1), and (4, 1) on teh coordinate plane. What would be the forth vertex on the coordinate plane below?
Answer:
The fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex]. The graph of the figure is included below.
Step-by-step explanation:
Let be [tex]X(x,y)[/tex], [tex]Y(x,y)[/tex], [tex]Z(x,y)[/tex] and [tex]W(x,y)[/tex] so that a rectangle is formed. Hence, we must satisfy the following conditions:
[tex]X(x,y) = (a, c)[/tex] (1)
[tex]Y(x,y) = (a, d)[/tex] (2)
[tex]Z(x,y) = (b, c)[/tex] (3)
[tex]W(x,y) = (b, d)[/tex] (4)
[tex]a < b[/tex] (5)
[tex]c < d[/tex] (6)
If we know that [tex]a = -1[/tex], [tex]b = 4[/tex], [tex]c = -1[/tex], [tex]d = 1[/tex], then we have the following points:
[tex]X(x,y) = (-1, -1)[/tex]
[tex]Y(x,y) = (-1, 1)[/tex]
[tex]Z(x,y) = (4, -1)[/tex]
[tex]W(x,y) = (4,1)[/tex]
Then, the fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex].

Find the volume of the rectangular prism?
Write your answer in simplest form.
what is the product of 4n/4n-4 * n-1/n+1
Answer:
x/x+1
Step-by-step explanation:
[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]
start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)
So the fraction would be 4n/4(x-1)
Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses
The new equation would be
n*n-1/n+1
Now just multiply:
x/x+1
Answer:
B.) n/(n+1)

Theresa rolls a 12-sided dice and flips a
coin. What is the probability that she will
roll a 7 and land on heads?
Answer:
The probability is 1/24
Step-by-step explanation:
For a 12-sided dice, there are 12 different possible results
so the possibility of rolling a 7 is just one of the results
The probability of this is simply 1/12
For landing on head, the probability is 1/2
So the probability of the event occurring is the product of these two events
We have this as;
1/2 * 1/12 = 1/24
f(x)= x^2 - 7x +12
The above equation is in standard form. Write the above equation in factored form
f(x) = (x-r1)(x-r2)
r1 represents first root, r2 represetnts second root
What are the roots?
Remember, x-r1 = 0 and x-r2=0
Answer:
f(x) = (x - 3)(x - 4)
Step-by-step explanation:
f(x)= x^2 - 7x +12 factors immediately into f(x) = (x - 3)(x - 4).
The roots are {3, 4}
The point (–3,2,–2) lies in the VI octant.

Answer:
m<A=94
Step-by-step explanation:
(2x+10)+(2x+2)=180
4x+12=180
-12 -12
4x=168
/4 /4
x=42
m<A= 2x+10
m<A=2(42)+10
m<A=84+10
m<A=94
Check:
Add m<A and m<B which should equal 180.
m<B=2x+2
m<B=2(42)+2
m<B=84+2
m<B=86
94+86=180
Find the perimeter of a regular octagon with an apothem of 6 feet and an area of 120 square feet
Step-by-step explanation:
A = (n × s × a)2 A = ( n × s × a ) 2
(120×6)2
240×12
2880
The perimeter of the Octagon is P = 30 feet
What is the perimeter of a polygon?The perimeter of the regular polygon with apothem and area is given by the equation
Perimeter of Polygon P = ( Area x 2 ) / Apothem
where apothem is a line from the center of a regular polygon at right angles to any of its sides
Given data ,
Let the perimeter of the octagon be represented as P
Now , the apothem a = 6 feet
The area of octagon A = 120 feet²
where Perimeter of Polygon P = ( Area x 2 ) / Apothem
P = ( 120 x 2 ) / 6
P = 30 feet
Therefore , the value of P is 30 feet
Hence , the perimeter of polygon is 30 feet

Math 8th Grade
Answer:
B = -1
Your answer would be C
Answer:
b = -1
Step-by-step explanation:
-3(2x - 3) + 5x = bx + 9
-3 x 2x = -6x
-3 x -3 = 9
-6x + 9 + 5x = bx + 9
-6x + 5x = -1x
-1x + 9 = bx + 9
(cancel out everything except -1 and b)

A plumber charges $75 for the service call and $25 per hour (h) for repairs. Write an algebraic expression to represent the total bill for all plumbing services.
A.
(75 + 25)h
B.
75 + 25h
C.
75h + 25
D.
75 + 25 + h
Answer:B i think if wrong im so sorry
Step-by-step explanation:
Answer:
B 75+25h
Step-by-step explanation:
$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.
Angel has a bag that contains orange chews, cherry chews, and lime chews. He performs an experiment. Angel randomly removes a chew from the bag, records the result, and returns the chew to the bag. Angel performs the experiment 52 times. The results are shown below:
A orange chew was selected 10 times.
A cherry chew was selected 20 times.
A lime chew was selected 22 times.
Based on these results, express the probability that the next chew Angel removes from the bag will be a flavor other than lime as a percent to the nearest whole number.

what is 2.1 times 3.2 find the missing partial products HELP.
Given:
The area model for [tex]2.1\times 3.2[/tex].
To find:
The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
[tex]2\times 3=6[/tex]
[tex]2\times 0.2=0.4[/tex]
[tex]0.1\times 3=0.3[/tex]
[tex]0.1\times 0.2=0.02[/tex]
The complete area model is shown below.
After adding all areas of the area model, we get
[tex]6+0.4+0.3+0.02=6.72[/tex]
Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
Consider the line shown on the graph below. Enter the equation of the line in the form y = mx + b where m is the slope and b is the y-intercept. Enter the equation of the line in the form y=mx + b where m is the slope.

A rectangular city lot has an area of 1000 square meters. If the length of the lot is 10 meters more than twice its width, find its length and width.
Answer: l=50 m, w=20 m
Step-by-step explanation:
Given
A rectangular city has an area of [tex]1000\ m^2[/tex]
Also, length is 10 m more than twice its width
suppose width is w
So, length is given by
[tex]\Rightarrow l=10+2w[/tex]
The area is given by
[tex]\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m[/tex]

Josh is going to the store with $60 to buy candy. bags of candy corn cost $3 & bags of chocolate cost $5 he needs to buy at least 20 bags of candy.
What do I put for the blank space? 3x+5y_60
Answer:
3a+5b
Step-by-step explanation:
Variable 1: a = candy corn
Variable 2: b = chocolate
Inequality 1: 60 ≥ 3a + 5b
Inequality 2: 20 ≤ 3a + 5b
The inequalities are as such because Josh needs to spend no greater than $60. He must also buy at least 20 bags of candy. The candy corn costs $3, while the chocolate costs $5. An expression for the total cost of the candy would be 3a + 5b.
