"The correct answer is that diagrams showing how matter moves through organisms and the environment are called cycles because they depict continuous, circular pathways.
In ecosystems, matter is not created or destroyed but is continuously recycled. This recycling process occurs in a loop or cycle, where matter moves from the environment to organisms and then back to the environment. For example, in the carbon cycle, carbon dioxide is taken in by plants during photosynthesis, then passed on to animals that consume the plants, and eventually returned to the environment through processes like respiration and decomposition.
These cycles are essential for the sustainability of ecosystems because they ensure that nutrients and other materials are reused and not depleted. The term ""cycle"" reflects the repeating and ongoing nature of these processes, highlighting the interconnectedness and interdependence of organisms and their environment. By using diagrams to represent these cycles, we can visualize and better understand the complex interactions and pathways that matter follows in ecosystems."

(a) 2x + 3x - 6 = 10 + 4x
(b) 17 + 5x = 23 + 4x - 6 + x
(c) 7x + 4 = 5x + 8 + 2x - 10
a. 2x+3x-6=10+4x
5x-6=10+4x

infinite number of solutions
c. 7x+4=5x+8+2x-10
7x+4=7x-2
no solution
(a) 2x + 3x - 6 = 10 + 4x ---> Answer: x = 16, it has one solution, it is an identity.
Adding the like terms on the same side of the equation to solve for x:
2x + 3x - 4x = 10 + 6
x = 16
(b) 17 + 5x = 23 + 4x - 6 + x ---> Answer: it has infinite number of solutions, it is a contradiction
Adding the like terms on the same side of the equation to solve for x:
5x - 4x - x = 23 - 17 - 6
5x - 5x = 6 - 6 (this equation is cancelling everything on each side so it can not be true no matter what value we assign, therefore it has infinite number of solution)
(c) 7x + 4 = 5x + 8 + 2x - 10 ---> Answer: no solution, its a contradiction.
Adding the like terms on the same side of the equation to solve for x:
7x - 5x - 2x = -10 + 8 - 4
7x - 7x = -6 (the terms of x are cancelled by each other, therefore no solution.

Which of the following is an example of a chemical change?
Select one:
a. The shell of an egg breaks when it is struck against a hard surface.
b. A mixture of flour, sugar, eggs, and butter is baked to become a cake.
c. Flour and sugar are sifted together into a measuring cup.
d. Chocolate squares are melted to make cake icing.
The answer is B.
To find the answer you can immediately cross out A and C. You're left with a mixture of ingredients that turn into a cake or choclate melting. Chocolate melting is a physical change so by using the process of elimination you can conclude that B is the correct answer.
Answer:
The correct answer is option B.
Step-by-step explanation:
We call chemical change to the process where two or more substances are transformed into other substances.
During this change, the substances will have a modification in the structure of their molecules and their bonds.
In the case of the example we can see how different substances (flour, sugar, eggs and butter) will change the shape of their structure to form another substance: the cake. This cake will receive the name of product.
Given this information, we can say that the correct answer is option B.

The sum of two numbers is 12 the difference of the same is -4 formulate a system of equation and find the number
Answer:
The numbers are a= 4 and b= 8.
Step-by-step explanation:
Let the unknowns number be a and b.
assume a>b.
As per the given condition: The sum of two number is 12 and the difference of the same is -4.
from the above conditions we have:
[tex]a+b =12[/tex] ......[1]
[tex]a-b=-4[/tex] ......[2]
Now, adding equations, we will eliminate b leaving an equation in a that we can solve:
⇒ [1]+[2] gives;
[tex](a+b)+(a-b)=12+(-4)[/tex] or
[tex]a+b+a-b=12-4[/tex]
Simplify:
[tex]2a=8[/tex]
Divide by 2 on both sides, we get
[tex]\frac{2a}{2}= \frac{8}{2}[/tex]
Simplify:
a=4
Substitute the value of a= 4 in equation [1] . to solve for b;
[tex]4+b=12[/tex] or
b= 12-4 =8
Therefore, the numbers a and b are 4 and 8

Find a number whose product with six is the same as its sum with 45
1. Make the equation. The product of the number and 6 equals the sum of the number and 45, so the equation would be 6x = x + 45.
2. Subtract x from both sides. You'll get 6x - x = 45.
3. You can combine like-terms by subtracting 6x - x. This is the same as 6x - 1x, which is 5x. You'll get 5x = 45.
4. Divide both sides by 5 to get x = 9.
Therefore, the number is 9.

Sonny Siebert earned $485,000 a year as a rookie pitcher for the Cleveland Indians. Assuming a tax rate of 6.2% for Social Security up to $118,500 and Medicare tax of 1.45%, how much did Sonny pay in FICA taxes as a rookie pitcher?
Answer:
14379.50
Step-by-step explanation:
If I remember correctly, the Medicare tax is taken on Gross Income. The question has already limited the base amount for Social Security.
Social Security: 118,500 * 6.2/100 = 7347
Medicare Tax: 485,000*1.45/100 = 7032.50 Add
Add 14379.50
Sonny paid 14370 in taxes for these 2 items.
Answer:
$14,379.50
Step-by-step explanation:
Given that:
Sonny Siebert Income: $485,000Social Security tax rate: 6.2% up to $118,500Medicare tax of 1.45%As we know that, the Federal Insurance Contributions Act (FICA) is made up of two items, Social Security and Medicare taxes.
So
Social Security tax: $118,500*6.2% = $7347
Medicare tax: $485,000*1.45% = $732.5
=> the amount of FICA taxes as a rookie pitcher she needs to pay is:
= $7347 + $732.5
= $14,379.50

John played a note on his tuba that vibrated the air 120 times per second. If you play the note for 4 seconds, how many times in the air vibrate?
480
This is this awnser because its 120 a second, for 4 seconds so 4 times 120 = 480.
Well the equation is rate*time=work/distance(in this case total vibrations)
Now we plug in the numbers:
(we know that 120 times per second is the rate because it uses the word per)
(4 seconds is the time because the unit is just seconds)
12*4=48*10=480
120*4=480
The answer is 480 vibrations

Use traditional algorithm to find the quotient 3 ) 137
Using the traditional division algorithm, 137 divided by 3 equals 45 with a remainder of 2.
Explanation:To find the quotient of 3 divided into 137 using the traditional divisor algorithm, we take it step by step. Starting from the left, we see if 3 fits into the first digit, 1. It does not, so we look at the next digit, making it 13. 3 fits into 13 four times. Write this 4 on top of the division line. Then you subtract the value of 4 times 3, or 12, from 13 to get a remainder of 1. Bring down the next digit from the dividend, so now we're dividing 3 into 17. 3 fits into 17, five times. Write this 5 on top of the division line. Therefore, 137 divided by 3 using traditional division algorithm equals 45 remainder 2.

What is 2.26 (26 repeating)as a fraction
The repeating decimal 2.26 (with 26 repeating) is converted to a fraction by setting it as 'x', scaling by 100, subtracting the original x, and then simplifying to get the fraction 224/99.
To convert the repeating decimal 2.26 (with 26 repeating) to a fraction, we use the following steps:
Let x = 2.262626..., which is the number we want to express as a fraction.Multiply x by 100 (since the repeating part is two digits long), so 100x = 226.262626....Subtract the original number x from this new number, so 100x - x = 226.262626... - 2.262626..., which gives us 99x = 224.Now, divide both sides by 99 to solve for x. Therefore, x = 224 / 99.We now have our fraction, which is 224/99.
