At an animal shelter, there are 15 dogs and 12 cats.
What percent of the number of cats is the number of
dogs?
Answer:
Dogs: 44.44 Cats: 55.556
Step-by-step explanation:
*this is only if you are allowed to use a calculator*
1. You have to add the total of the cats and dogs
Why? Here, let me put it this way. You have a test with two sections: math and science. If there are 2 Maths Questions and 2 Science questions, what percent of the test are math questions? You would not say 2/2 and say 100. You would say 2/4 because it is obvious. You do the same in this case but it is not as noticeable because you are dealing with bigger numbers.
15 + 12 = 27.
2. Solve
a. There are 15 dogs and 12 cats that makes up 27 pets total.
So you have to do 12/27 for cats,
15/27 for dogs. The fractions equal one and It shows you how much of one is there compared to the total.
b. Simplify
You can simplify these fractions:
for 12/27, divide the numerator and the denominator by 3.
You get 4/9
Divide 15/27 for dogs by 3 as well to get 5/9.
5+4 is 9, which means that I am doing the math correctly.
According to the calculator, 5/9 is 55.556, and 4/9 is 44.444
They should be accurate because there are more dogs than cats and the percentage for dogs are higher. Hence, this is correct.
Cats = 4/9 = 44.444%
Dogs = 5/9 = 55.556%
Hope this helps :)

A company manufactures and sells video games. A survey of video game stores indicated that at a price of $88 each, the demand
would be 200 games, and at a price of $38 each, the demand would be 1,200 games. If a linear relationship between price and
demand exists, which of the following equations models the price-demand relationship?
(Let x represent the price per video game and y represent the demand.)
A
y = 20x- 1,560
В.
y = 20x
C.
y = -20x + 1,960
D.
y = -20x + 1,560
The price-demand relationship of the company is a linear model
The equation that models the price-demand relationship is y = -20x + 1960
How to determine the linear relationship?From the question, we have the following points:
(x, y) = (88, 200) and (38, 1200)
The equation of the linear relationship is then calculated as:
[tex]y = \frac{y_2 - y_1}{x_2 -x_1} * (x - x_1) + y_1[/tex]
Substitute known values in the above equation
[tex]y = \frac{1200 - 200}{38 -88} * (x - 88) + 200[/tex]
Evaluate the difference
[tex]y = \frac{1000}{-50} * (x - 88) + 200[/tex]
Evaluate the quotient
[tex]y = -20 * (x - 88) + 200[/tex]
Expand
[tex]y = -20x + 1760 + 200[/tex]
Evaluate the sum
[tex]y = -20x + 1960[/tex]
Hence, the equation that models the price-demand relationship is y = -20x + 1960

What is the value of k?

Answer:
9514 1404 393
Step-by-step explanation:
k = 2
The point (0, 0) on the graph of f(x) tells you f (0) = 0.
The point (-4, 0) on the graph of g(x) tells you g (-2) = 0.
Now we know that
g(-2) = 0 = f(0) = f(-2+k)
or ...
0 = -2+k
2 = k
The value of k is 2
so the answer to you problem is k=2

The graph below shows the relationship between test grades and shoe sizes of the students in Dexter's class.
A:positive linear association
B:Negative linear association
C:Nonlinear association
D:No association
The scatterplot can show an association or no association, at all.
The type of association shown by the graph that relates test grades and shoe sizes of the students in Dexter's class is no association
How to determine the association?When the points on the graph of the scatter plot follows an approximately, straight line; then the relationship is a linear relationship.
If it follows a curve, then it is a nonlinear relationship
If the points are scattered, then it shows no association.
The points on the graph are scattered, and they do not follow a specific pattern.
Hence, the graph shows no association

Isoke is solving the quadratic equation by completing the square. 10x2 40x-13=0 10x2 40x=13 A(x2 4x)=13 What is the value of A? -13 4 10 40.
The value of A in solving the considered quadratic equation by completing the squares method is given by: Option
What is completing the squares method for solving the quadratic method?Suppose the considered quadratic equation is of the form [tex]ax^2 + bx + c = 0[/tex]
Then, completing the squares method tries to make a squared term in terms of x in the left side, so that x comes in linear form, instead of quadratic, as shown below:
[tex]ax^2 + bx + c = 0\\ax^2 + bx = -c\\\\\text{Multiplying 4a on both the sides}\\4a^2x^2 + 4abx = -4ac\\\\\text{Adding }b^2\text{ on both the sides}\\4a^2x^2 + 4abx + b^2 = b^2 -4ac\\or\\(2ax +b)^2 = b^2 - 4ac\\2ax + b = \pm \sqrt{b^2 - 4ac}\\\\x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
This provides two solution to the considered quadratic equation. These solutions can be real, or imaginary.
For the considered case, the quadratic equation is:
[tex]10x^2 + 40x - 13 = 0[/tex]
Applying the method as Isoke did, we get:
[tex]10x^2 + 40x - 13 = 0\\10x^2 + 40x = 13\\10(x^2 + 4x) = 13[/tex]
Therefore, we get the value of A as 10.
