For the given right angled triangle, the base of the triangle is 10 units and perpendicular side is 9 units then its side length x is equal to 13.45 units (nearest hundredth).
As given in the question,
Given right angled triangle,
Base of the triangle is equal to 10 units
Perpendicular side of a triangle is equal to 9 units
Side length 'x' is the hypotenuse of the right angled triangle.
Using Pythagoras theorem we get,
(Hypotenuse)² = ( Base)² + ( Perpendicular side)²
⇒ x² = (10)² + (9)²
⇒ x² = 100 + 81
⇒ x² = 181
⇒ x = √181
⇒ x = 13.4536...
⇒ x = 13.45 units ( nearest hundredth)
Therefore, for the given right angled triangle, the base of the triangle is 10 units and perpendicular side is 9 units then its side length x is equal to 13.45 units (nearest hundredth).

2 step equation:12. Amy wants to start taking gymnastics. There is a one-time fee of $35 to sign up, then it costs $85 per month. If Amy saves up $225, how many months of gymnastics can she take?
Answers
The number of months Amy can take the Gymnastic = 2 months.
Amy wants to start taking gymnastics.
The fee structure of the gymnastics is divided into two parts.
There is a one time fee payment of 35$ 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 .

Answers
If Robin says, "I can find 6 × 9 by multiplying 4 X 9 and doubling it, her statement didn't make any sense because it is not possible.
What is distributive property?
The same outcome will be obtained by multiplying the sum of two or more addends by a number as it is by multiplying each addend separately by the number and then adding the resulting products.
A × (B + C) = AB + AC
A (B - C) = AB - AC
Here,
we can write 6 × 9 as,
= 6 × 9 = 6 × (6 + 3) = (6 × 6) + (6 × 3), by applying distributive property

Answers
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).

In the given question,
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 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
What is an Equation?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

Answers
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.

undergraduate students and male undergraduate students who were enrolled.
The number of female undergraduate students was
thousand.
Answers
Answer: 231 thousand
Step-by-step explanation:
given,
total number of undergraduate students enrolled = 414000
let us take number of total number of male students as, X
then, total number of female students will be X + 48000
now we get,
total number of male students + total number of female students = total number of students enrolled.
X + (X + 48000) = 414000
X + X + 48000 = 414000
2X = 414000 - 48000
X = 366000/2
X = 183000
total number of male students is 183000
total number of female students is
X + 48000
183000 + 48000 = 231000
A study was commissioned to find the mean weight of the residents in certain town. The study found the mean weight to be 193 pounds with a margin of error of 9 pounds. Which of the following is not a reasonable value for the true mean weight of the residents of the town?
Answers
Considering the confidence interval, the non-reasonable value for the true mean weight of the residents of the town is:
A value that is less than 184 or more than 202.
How to obtain the confidence interval?The confidence interval for a population mean is given by the point estimate of this mean, which is the sample mean, plus/minus the margin of error.
For the context of this problem, these parameters are given as follows:
Point estimate: 193 pounds.Margin of error: 9 pounds.Hence the lower bound of the interval is:
193 pounds - 9 pounds = 174 pounds.
The upper bound of the interval is:
193 pounds + 9 pounds = 202 pounds.
All the values that are in the interval are reasonable values for the population mean, hence, in the context of this problem, the not reasonable values are given as follows:
A value that is less than 184 or more than 202.

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)

What is the Present Value of Annuity?
An annuity is defined as a fixed amount of cash that is received or paid periodically over a certain period of time. This would mean that the amount in each cash flow of the annuity would be equal and occur for a specific period of time.
The formula for present value is;
PV = P[1 - (1 + r)⁻ⁿ)/r]
where;
PV is present value
P is periodic cash flow
r is interest rate
n is time
We are given the following;
Periodic cash flow (P) = $2525 /Year
Interest rate (r) = 10% /Year = 0.1
Time (n) = 16 Year (from 9 years to 24 years)
Thus;
PV = 2525[1 - (1 + 0.1)⁻¹⁶)/0.1]
PV = $19754.86
This is the present value in 9 years
Thus, the present value in 24 years which is now will be expressed by the formula;
PV = FV/(1 + i)^(t)
where;
PV is present value
FV is future value
i is interest rate
t is time
Thus;
PV = 19754.86/(1 + 0.1)^(8)
PV = $9215.77
