The unit rate of the plant growth is 5cm per hour

The unit rate refers to amount the plant will grow 1 hour

from the relationship

15 cm = 3 hours

? cm = 1 hour

cross multiplying

3 * ? = 15 * 1

? = 15 / 3

? = 5 cm

Answer:

Doesn't make a lot of sense. Can you be more specific.

Step-by-step explanation:

The number of months Amy can take the Gymnastic = 2 months.

Amy wants to start taking gymnastics.

The fee structure of the gymnastics is divided into two parts.

There is a one time fee payment of 35$ and there is a monthly payment that costs 85$ per month.

So the first month fee of the gymnastics = 35 + 85 = 120$

Savings of Amy = 225$

If Amy pays the 1st month fee ,

then the she will be left with the savings  = 225$ - 120$ = 105 $

It means Amy can join the gymnastics for one more month .

Hence the number of months Amy can take the Gymnastic = 2 months .

The length of shortest piece is 4 inches, middle sized piece is 9 inches and that of longest piece is 27 inches.

According to the question,

We have the following information:

A piece of pipe is 40in. long. It is cut in to 3 pieces. The longest piece is 3 times as long as the middle sized piece and the shortest piece is 23 in. shorter than the longest piece.

Let's take the length of middle sized piece to be x inches.

Length of longest piece = 3x inches

Length of shortest piece = (3x-23) inches

Now, we have the following expression:

x+3x+3x-23 = 40

7x-23 = 40

Adding 23 on both the sides:

7x = 40+23

7x = 63

Dividing by 7 on both the sides:

x = 63/7

x = 9 inches

Length of longest piece = 3*9 inches

Length of longest piece = 27 inches

Length of shortest piece = (27-23) inches

Length of shortest piece = 4 inches

Hence, the length of shortest piece is 4 inches, middle sized piece is 9 inches and that of longest piece is 27 inches.

The ordered pairs of the function, h(x) = 3x², are (1,3) and (-1,3).

According to the question,

We have the following information:

h(x) = 3x²

Now, we will look at the options to know the correct option of ordered pairs.

Now, in the options, there are only two values of x (1 and -1). So, we will solve the given function using these two values and we will find the value of h(x).

h(x) = 3x²

h(1) = 3*1*1

h(1) = 3

So, the first ordered pair is (1,3).

When x = -1:

h(x) = 3x²

h(-1) = 3*-1*-1

h(-1) = 3

Now, the second ordered pair of the function is (-1,3).

Hence, the correct options are A and C.

The turning point is at x = 5, and this means that the substance changes from liquid to gas when x = 5.

Here we have the temperature function:

T(x) = (x - 5)^3 + 9

The turning point is the point where the curvature of the function changes,  by differentiating the function two times and finding the zero, we can get the turning points.

T'(x) = 3*(x - 5)^2

T''(x) = 3*2*(x - 5) = 6*(x - 5)

This is zero when x = 5, then:

T''(5) = 6*(5 - 5) = 0

So the turning point is there.

Using the graph, the hourly wage of the employees is: $8 per hour.

Slope of a proportional graph is the unit rate between two variables, x and y, and it is calculated as: k = y/x.

To find the unit rate or slope of the graph, use any point on the graph (x, y).

The unit rate of the graph in the image above is the hourly wage of the employees.

Using any point on the line, say, (13, 104), we can find the slope/unit rate. Therefore:

Unit rate/slope, k = 104/13

Unit rate/slope, k = 8

Answer:

to find the answer you just need to divide 3 out of 141

141÷3=47seeds per each student

3x=141

x=141÷3

x=47

The equation is represented as A = S/3 , where S is the total number of seeds and A is the number of seeds planted by each student and the value of A = 47 seeds

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of seeds by each student be A

Now , the equation will be

The total number of seeds be S = 141 seeds

The number of students be n = 3 students

So , the total number of seeds planted by each student A = total number of seeds S / number of students n

A = S / n

Substituting the values in the equation , we get

Total number of seeds planted by each student A = 141 / 3

Total number of seeds planted by each student A = 47 seeds

Therefore , the value of A is 47 seeds

A medical research study on a new medicine for multiple sclerosis is being conducted with 24 patients.

After the study was concluded, it was concluded it was determined that 15 patients reacted favorably to the medicine, 7 reacted unfavorably, and 2 were unaffected.

If three of the patients are randomly selected, then we have to determine the probability that none of the patients reacted favorable.

Total patient are 24.

The patients reacted favorably to the medicine is 15.

The patients reacted unfavorably to the medicine is 7.

The patients unaffected to the medicine is 2.

Randomly selected patients are 3.

So the probability that none of the patients reacted favorable

P(E) = 9/24 × 8/23 × 7/22

Simplifying

P(E) = 9/3 × 1/23 × 7/22

P(E) = 3 × 1/23 × 7/22

P(E) = 21/506

The simplified form of the expression, 5³.5 will be 625.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that the expression is, 5³.5

=5³.5

The base should remain constant and the exponents added when multiplying like bases. Keep the base constant when raising a base with power to another power, and multiply the exponents instead. Keep the base constant and deduct the exponents in the denominator and numerator when dividing like bases.

Apply the law of exponent as

xᵃ × xᵇ = xᵃ⁺ᵇ

=5³⁺¹

=5⁴

=5x5x5x5

=625

Thus, the simplified form of the expression, 5³.5 will be 625.
