The lengths 9, 9 / 2 and 9√3 are not part of a 30 - 60 - 90 right triangles. (Correct choice: A)
What set of measures are associated with a 30 - 60 - 90 right triangles?
Herein we must find what set of lengths are part of a 30 - 60 - 90 right triangle. In accordance with the Euclidean geometry, there are the following relationships for the sides of the 30 - 60 - 90 right triangle:
The longest leg is √3 times the length of the shortest leg.The hypotenuse is 2 times the length of the shortest leg.The hypotenuse is 2√3 / 3 times the length of the longest leg.Now we proceed to check if each set of sides belongs to a 30 - 60 - 90 right triangle:
Case 1
The length of the shortest leg of the triangle is 9 / 2, then the lengths of the longest leg and the hypotenuse are 9√3 / 2 and 9, respectively. (False)
Case 2
The length of the shortest leg of the triangle is 4, then the lengths of the longest leg and the hypotenuse are 4√3 and 8, respectively. (True)
Case 3
The length of the shortest leg of the triangle is 7, then the lengths of the longest leg and the hypotenuse are 7√3 and 14, respectively. (True)
Case 4
The length of the shortest leg of the triangle is 5 / 3, then the lengths of the longest leg and the hypotenuse are 5√3 / 3 and 10 / 3, respectively. (True)

work out the surface area of the prism
The surface area of the prism is 200 cm².
The surface area of the prism is given by the formula:
Surface area (S) = 2 B + p h
where B is the area of base of prism
p = perimeter of base
h = height of the prism.
Perimeter = 2(5 + 3) cm
p = 16 cm
B = 5 cm × 4 cm = 20 cm²
h = 10 cm
Substituting it in the formula, we get that:
S = 2 B + p h
S = 2 (20) + (16) (10)
S = 40 + 160
S = 200 cm²
Therefore, we get that, the surface area of the prism is 200 cm².

a charity benefit is attended by 25 people and three gift certificates are given away as door prizes: one gift certificate is in the amount of $100, the second is worth $25 and the third is worth $10. assuming that no person receives more than one prize, how many different ways can the three gift certificates be awarded?
Number of ways that the three gift certificates can be awarded = 13800 ways
There are a total of 25 people attended the charity benefit. There are three gift certificates: one gift certificate is in the amount of $100, the second is worth $25 and the third is worth $10.
Assume that no person receives more than one prize.
One of the 25 people can get gift certificate of $100.
⇒ 25 ways for $100 gift certificate.
Then remaining 24 people are considered for further counting.
One of the 24 people can get gift certificate of $25.
⇒ 24 ways for $25 gift certificate.
Now there are 23 people remained.
One of the 23 people can get the $10 gift certificate.
⇒ 23 ways for $10 gift certificate.
Therefore, Number of ways that the three gift certificates can be awarded = 25 x 24 x 23 = 13800 ways.

which type of transformation preserves the symmetry of an even function f(x) but does not preserve the symmetry of an odd function g(x)?vertical translationhorizontal translationreflection over the x-axisreflection over the y-axis
The type of transformation that preserves the symmetry is Vertical translation.
For instance, a parabola is still symmetric about the y-axis if you move it up. It loses its symmetry if you move it to the left or right. Reflection keeps both even and odd functions symmetrical.
What is the difference between even and odd function ?The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin [tex](0, 0)[/tex].

At the end of 1994 Walters Was half as old as his grandmother. The sum of the years in which they were born in 3838. How old will Walter be at the end of 1999?
The age of Walter at the end of year 1999 will be equal to 55 years.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
Let's assume respective age of Walter and Walter's grandmother is x and y years respectively.
In 1994 , age of Walter was :
x = y / 2
or y = 2x
It is also given that the sum of years they were born is 3838.
The year Walter was born = (1994 - x)
The year Walter's grandmother was born :
= (1994 - y)
= 1994 - 2x (∵ y = 2x)
So , we can write an equation to find out Walter's age which is :
1994 - x + 1994 - 2x = 3838
3988 - 3x = 3838
3x = 3988 - 3838
x = 150 / 3
x = 50 years
or the age of Walter in 1994 is 50 years.
At end of 1999 Walter's age will be:
= 50 + 5.
= 55 years
Therefore , the age of Walter at the end of year 1999 will be equal to 55 years.

The random sample proportion.
Probability distribution is a statistical function that describes all the possible values and likelihoods that a random variable can take within a given range.
at 90% confidence interval: The Central 90% of any normal distribution is: Z_(α/2) = 1.960
Error = E = ±5% = ±0.05
Applying the normal Probability distribution
= 0.70 ≤ P≤ 0.77(this means that we are 90% confident that the true proportion of jet with wiring problem fall with 0.70 and 0.77, hence there is no need for the airline to conduct further sampling, rather, they should just inspect all the planes)

Mariana is younger than yaritza. their ages are consecutive odd integers. find mariana's age if the sum of mariana's age and 5 times yaritza's age is 100.
Translating the given word problem into a set of linear equations, Mariana's age is 15 years old.
Translate the given word problem into algebraic equations.
Let x be Mariana's age
Let y be Yaritza's age
Mariana is younger than Yaritza, their ages are consecutive odd integers.
Since the difference of consecutive odd integers is 2, then:
y = x + 2 ....... (1)
Sum of Mariana's age and 5 times Yaritza's age is 100.
x + 5y = 100 ..... (2)
Substitute equation (1) to equation (2)
x + 5y = 100
x + 5(x+2) = 100

It can be determined that a relation represented as an equation is a function if and only if for each value on x-axis, there is a corresponding value on Y-axis.
which also signifies that for each value of x , there is a value of y which exists and is real.
A function is a mapping from one set to another such that nothing in the first set is mapped to more than one thing in the second set.
Or in simple words if there is no corresponding value of y for any x, then that is not a function.

An equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples is,
⇒ b = 2a + 30
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Cost of one pound of grapes = g
Cost of one pound of apples = a
Cost of one pound of banana = b
Since, The cost of one pound of grapes is 15 cents more than one pound of apples.
It can be written as;
g = a + 15 .... (i)
And, The cost of one pound of bananas is twice as much as one pound of grapes.
It can be written as;
b = 2g ..... (ii)
To find an equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples as,
Put the value of g from (i) in (ii) we get,

An angle measures 84.2° less than the measure of its supplementary angle. What is the measure of each angle?
The measure of the supplementary angles are 48° and 132°.
Let the measure angle be x.
Its supplementary angle will be x + 84
We know that the sum of supplementary angles is 180°.
So, we get the equation as:
x + x + 84 = 180
Combining the like terms, we get that:
2 x + 84 = 180
Subtract 84 from both sides, we get that:
2 x = 180 - 84
2 x = 96
Divide both sides by 2, we get that:
x = 96 / 2
x = 48°
x + 84 = 48+ 84 = 132°
Therefore, we get that, the measure of the supplementary angles are 48° and 132°.
