Step-by-step explanation:

Answer: D. The fungus and bacteria organisms are obtaining the energy they need by decomposing organic matter like dead trees and old apples.

Fungi is the primary decomposer of biological waste in forest ecosystem. Fungi grows on the branching network of hyphae which provide it more penetration potential towards the litter. Wood decaying fungi has enzymes required for decomposition of lignin, a chemical substance found in wood. Fungi decompose organic matter by releasing enzymes which breaks down the decaying matter, after that they absorb the nutrients in the decaying material. The left residue in the organic matter includes sugars and amino acids are degraded and decomposed by the bacteria.

Final answer:

The range of a relation is the set of all possible y-values. For the given table, the range is -3, 0, 1, 2, and 3, which corresponds to answer D.

Explanation:

You're asking to identify the set of numbers that makes up the range in the given relation. The range of a relation refers to all the possible values of y that you can get when you input various values of x. For your table, the y-values are -3, 0, 1, 2, and 3. So, the range is the set of these y-values. Therefore, the correct answer is D. -3, 0, 1, 2, 3.

In general, to find the range, you look at all the second numbers in the ordered pairs of a relation or function. When plotted on a graph, this shows the dependence of y on x.

Answer:

3.31 pounds of eggs will be required to prepare the recipe.

Step-by-step explanation:

Since 1 kilogram = 2.205 pounds is the scale by which we can convert the unit kilograms into pounds

∵ 1 kilogram = 2.205 pounds

∴ 1.5 kilograms = 1.5 × 2.205

                         = 3.3069 pounds

                         ≈ 3.31 pounds

Therefore, 3.31 pounds of eggs will be required to prepare the recipe.

Answer:When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). ... Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure.

Step-by-step explanation:

Answer:

The properties of reflection are used when we want to reflect a figure across a specific line, it can be across y-axis, x-axis, y = x or y = -x.

In either case, the result is a reflection, that is, those lines will work as a mirror, having the same shape and size but reflected across the line.

It's important to say that a reflection is a rigid transformation, which means the shape or size of the figure won't chance.

If we want to reflect across the y-axis, the transformation is:

[tex](x,y) \implies (-x,y)[/tex]

Across the x-axis: [tex](x,y) \implies (x,-y)[/tex]

Across the line y = x: [tex](x,y) \implies (y,x)[/tex]

Across the line y = -x: [tex](x,y) \implies (-y,-x)[/tex].

Answer:

40 and 0.5

Step-by-step explanation:

48 and 1/2 metres = 48.5 metres

1 and 1/5 metres = 1.2 metres

Take 48.5 and divide it by 1.2 and you will get 40.41666667...

Since the maximum whole number you can get is 40, you can cut 40 pieces of 1.2 metres of ribbon off.

Remainder = 48.5 - (40 x 1.2) = 0.5 metres left

The number of pieces of ribbon can be cut from roll is 40 and 0.5 m of ribbon left.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Karen had a roll of ribbon 48 1/2 m long.

= 48.5 m long

and, 1 and 1/5 m = 1.2 m

Now, the number of pieces of ribbon can be cut from roll is

= (48.5) / (1.2)

= 40.416

and, the amount of ribbon left

= 48.5 - (40 x 1.2)

=  0.5 m

∠4 = ∠7 ( vertical angles )

The angles are opposite angles of the vertex with the same straight lines

Angle 4 and 7 are vertically opposite angle.

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal.

in the given systems of line,

Angle 1, 2, 3, 4, 5, 6, 7, and angle 8 are given.

Answer:

A = {MOPN, MPON, PMON, POMN}

Step-by-step explanation:

Everyone has already agreed that Naim would be the last skater, so we have to make sure that the result has 'N' in each last place. As we can see, they all have this.

Now, we also have to make sure Oliver not first, because although they're trying to decide, the problem asks for the complement in which "Oliver is the first skater in the race."

A complement is all the values that are NOT in the set, so it cannot be A = {OPMN, OMPN) or A = {MOPN,MPON, OPMN, POMN), because they both have at least one case where 'O' is first.

A complement is ALL other values of the set, so it cannot be A = {MOPN, PMON}, because that set only shows two possible values.

Therefore, A = {MOPN, MPON, PMON, POMN} is your answer.

Answer:A=OPMN,OMPN

Answer:

30 Pages.

Step-by-step explanation:

We know that there are 60 minutes in an hour, and that 3 goes into 60 20 times (3/60 = 20). Multiply 1 1/2 x 20, and that equals 30 pages.

You can also set it up in fraction form - multiply 1.5/3 times x/60. cross multiply and solve for x. in this case x = 30.

The required solution is -63/4.

The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications

Given :

Step 1: Write down the question as an algebra problem, with the unknown as X

The unknown is a number plus 17, so we write it as (X+17). The product is four times (X+17), so we write it as 4(X+17). Set it equal to 5, as per the question,

4(X+17)=5

Step 2: Divide both sides by 4

4(X+17)/4=5/4

X+17=5/4

Step 3: Isolate X by subtracting 17 from both sides

X= 5/4-17

X= 5/4- (17*4)/4

X= 5/4-68/4

X=-63/4

Therefore, the required solution is -63/4.

Answer:

#17 Complementary

#18 Neither

Step-by-step explanation:

Complementary Angle: If sum of two angles is right angle then both angles are complementary to each other.

Supplementary Angle: If sum of two angles is straight angle then both angles are supplementary to each other.

#17 In figure 1

∠1 + ∠2 = 90°

Sum of ∠1 and ∠2 is 90° which is right angle.

Therefore, ∠1 and ∠2  are complementary angles.

#18 In figure 1

Sum of ∠1 and ∠2 neither 90° not 180°

Therefore, ∠1 and ∠2  neither complementary angles nor supplementary angles.

The simplest form of '18' is '18'. In relation to the field trip, '18' represents the number of third-grade students who attended, which is half of the total group of 36 students.

This question is asking for us to simplify the number '18'. The simplest form of a number is itself when it cannot be divided evenly by any other numbers except for 1 and itself. In this case, the number '18' can be divided by 1, 2, 3, 6, 9, and 18. It cannot be simplified further because it does not have any other divisors aside from these. Therefore, the simplest form of '18' is '18'.

In the context of this question, if '18' represents the number of students in the third grade who went for the field trip, that refers to exactly half of the total group since there were 36 students in total.

Geometric

an=an-1₋(.25);a₁=192

an=192(.25)^n-1

7.32421875*10^−4

Step-by-step explanation:

Answer:

The sequence shown is geometric

Recursive function:

[tex]a_{n} = a_{n-1}\times r[/tex]

with [tex]a_1 = 192[/tex]          

Explicit function: [tex]a_n = 192 \times 0.25^{n-1} [/tex]

10th term: 0.000732421876

Step-by-step explanation:

In a geometric sequence the n+1 term divide by the n term is constant

48/192 = 0.25

12/48 = 0.25

3/12 = 0.25

From this result we can deduce the recursive function:

[tex]a_{n} = a_{n-1}\times r[/tex]

with [tex]a_1 = 192[/tex]          

Explicit function:

[tex]a_n = a \times r^{n-1} [/tex]

where a is the first term in the sequence (= 192) and r is the common ratio (= 0.25). Replacing:

[tex]a_n = 192 \times 0.25^{n-1} [/tex]

The 10th term is:

[tex]a_{10} = 192 \times 0.25^9 = 0.000732421876 [/tex]
