Based on the ratio of the weights of objects in Planet A to Planet B, an elephants weighing 4,500 pounds on Planet A would weigh 135 pounds on Planet B
How to find the weight?The ratio of the weight of an object in Planet A is 100 to 3 on Planet B. This means that every 100 pounds on Planet A is 3 pounds on Planet B.
If an elephant on Planet A is 4,500 pounds, on Planet B it would weigh:
Weight on Planet B = (4,500 x 3) / 100
Weight on Planet B = 13,500 / 100
Weight on Planet B = 135 pounds
In conclusion, the weight of the elephant on Planet B would be 135 pounds.

If Q = {all perfect squares less than 30} and p={ all odd numbers from 1 to 10}
When Q = {all perfect squares less than 30} and p={ all odd numbers from 1 to 10) Q ∩ P = { 1, 9}
How to calculate the value?Set theory simply means the branch of mathematical logic that deals with sets, that can be described as collections of objects.
It should be noted that perfect squares are the numbers that can be divided to give same number.
Q = {all perfect squares less than 30}. This will be 1, 4, 9, 16, 25
P ={ all odd numbers from 1 to 10}. This will be 1, 3, 5, 7, and 9.
In this case, the common numbers to set of P and Q are 1 and 9.
Therefore, the numbers are 1 and 9 since they're common to both sides.

Find the time-and-a-half pay rate by multiplying the hourly wage, $22 by
by 1-1/2
When the hourly wage is $22, the time-and-a-half pay rate is $
(Simplify your answer.)
consequently, the time and a half rate will be 33 dollars per hour according to the query.
What is the logic behind time and a half pay rate and how tocalculate it?A higher rate of pay known as "time and a half" is normally only applied to hours that are over 40 in a workweek or that are worked extra.
Companies have different overtime pay practices, with time and a half as a typical rate.
Simply said, it means that for each hour performed within the time and a half window, the employee will receive payment in addition to their regular hourly rate of one half of that amount.
Time and a Half Rate = Hourly Rate * 1.5
According to the given question:
Time and a half rate =22$*1-1/2
=22$*1.5
=33$ per hour
Therefore, According to the question given the Time and a pay half rate will

We have that the equation of a line in its slope and y-intercept form is the following:
[tex]\begin{gathered} y=mx+b \\ \text{where m is the slope and b is y-intercept} \end{gathered}[/tex]Now, when two equations are perpendicular, the slope of both are opposite, that is, the product between them is equal to -1, like this:
[tex]\begin{gathered} m_1\cdot m_2=-1 \\ -\frac{3}{4}\cdot m_2=-1 \\ m_2=\frac{4}{3} \end{gathered}[/tex]We replace the values of the point (-9, 6) and the slope to calculate the value of the y -intercept:
[tex]\begin{gathered} 6=-9\cdot\frac{4}{3}+b \\ b=12+6 \\ b=18 \end{gathered}[/tex]Therefore, the perpendicular equation that also passes through the point (-9,6) is:

The values of x = 14 and y = 12
In the diagram given, there are two parallel lines and three angles formed by cutting the parallel lines.
So here, angles (2x+7)° and (3x-7)° are corresponding angles.
That is they occupy relatively same position, that is both are above each parallel line.
So they are equal angles.
i.e., 2x+7 = 3x-7
⇒ 3x-2x = 7 +7
⇒ x = 14
Now the angles 2x+7° and 12y+1° are supplementary angles.
Supplementary angles are formed on a straight line between a line cutting the straight line.
That is their sum = 180°
i.e., 2x+7° + 12y+1° = 180
⇒ 2 x 14 + 7 + 12y +1 = 180
⇒ 28 + 8 +12y = 180
⇒ 36 +12y = 180
⇒ 12y = 180 -36
⇒ 12y = 144
⇒ y = 12

scores on an iq test are normally distributed. the test is designed so that the mean is 100 and standard deviation is 15. (a) what percentage of the population has an iq above 120?
From the normal distribution it is calculated that 9.18% of people has an iq over 120.
Normal distributions are crucial to statistics because they are widely used in the natural and social sciences to represent real-valued regressors with unknown distributions.
Some of their significance can be attributed to the central limit theory. This claim states that, in some cases, the average of many samples (observations) of a stochastic process with limited mean and variance constitutes itself as a random variable, whose distribution merges to a normal distribution as the number of samples increases.Because of this, the distributions of physical values, such as error margins, which are expected to be the sum of many independent events, are frequently near to normal.We have to find P( X > 120 )
Thus find z score for x =120
[tex]z=\frac{x-\mu}{\sigma}=\frac{120-100}{15}=\frac{20}{15}=1.33[/tex]
Thus we get:
P(X>120) = P(Z>1.33)
P(X>120) = 1 - P(Z<1.33)
P( Z < 2.67) = 0.9082
Thus
P(X>140) = 1 - P(Z<2.67)
P(X>140) = 1 - 0.9082
P(X>140) = 0.0918
Percentage = 9.18%
Therefore 9.18% of people has an iq over 120.

You need a 30% alcohol solution. On hand, you have a 75 mL of a 10% alcohol mixture. You also have 55% alcohol mixture. How much of the 55% mixture will you need to add to obtain the desired solution?
60 ml of the 55% solution is required to get the desired solution.
A unique kind of homogenous mixture made up of two or more substances is called a solution.
A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture. Polarity effects of chemicals are engaged in the mixing of a solution at a scale that leads to interactions that are very specific to solvation. When the solvent makes up a significant large portion of the combination, as is frequently the case, the solution typically or normally has the condition of the solvent. The concentration of a solution, which measures how much solute is present in a given volume of solution or solvent, is one crucial parameter.Let x ml of 55% solution is taken.
therefore alcohol = 0.55x ml
water = 0.45x ml
Now it is added to 10% 75 ml solution.
Alcohol = 10% of 75 = 7.5ml
Water = 67.5 ml
New mixture = 75 + x
Alcohol = 30% of (75+x) = 22.5 + 0.3x
Therefore 22.5 + 0.3x = 7.5 + 0.55x
or, x = 60 ml
Therefore 60 ml of the 55% solution is required.

Find the value of c that makes t^2 - 22t+ c a perfect square trinomial.
Write the expression as the square of a binomial.
The expression is
The expression is a perfect square trinomial if and only if c = 121.
How to get the value of c?
A perfect square trinomial is written as:
(a + b)^2 = a^2 + b^2 + 2ab
In this case, we have:
t^2 - 22t + c
We can rewrite this as:
t^2 - 2*11*t + c
Then we have:
a = t
b = -11
And we will have that:
c = b^2 = (-11)^2 = 121
Then we have:
t^2 - 2*11*t + 121
Which is a perfect square trinomial:
(t - 11)^2 = t^2 - 22t + 121

Question 9 of 12
AMORTIZATION Car loans are often spread into multiple regular payments over time. This process is called amortization. Each payment
reduces the remaining principal, and the interest accrued for the next payment is based on the reduced principal. The monthly payment is
fixed; so, with each subsequent payment, an increasing portion goes toward principal, and a decreasing portion goes toward interest. Lori
takes out a car loan of $15,000 for 3 years, with a 3% interest rate. When the loan is amortized into monthly payments, the total interest paid by
the end of the loan term will be $704.
Calculate the simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years.
$15
The simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years is $ 1,350.
It is given in the question that:-
Principal = $15,000
Time period = 3 years
Interest rate = 3 %
Total interest paid by Lori, if the loan was amortized = $ 704.
We have to find the simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years.
We know that,
Simple interest = (Principal*Rate*Time)/100
Hence,
Simple interest = (15000*3*3)/100 = $ 1350.

Find the range of possible values for k.
The possible values of k such that the quadratic equation has real distinct roots are 1 / 2 and 2.
What are the possible values of k associated to quadratic equation?
In this problem we find the case of a quadratic equation, of which the values of a variable k must be found such that the polynomial have real distinct roots. This can be done by using the discriminant of the quadratic formula, which is defined below:
For a · x² + b · x + c = 0, the discriminant is:
b² - 4 · a · c > 0
Then, if we know that a = k - 1, b = 2 and c = 2 · k - 3, then the possible values of k are:
2² - 4 · (k - 1) · (2 · k - 3) > 0
4 - (4 · k - 4) · (2 · k - 3) > 0
