A cat gave birth to 11 calico kittens and 16 non-calico kittens. What is the ratio of calico kittens to non-calico kittens?

Answer:

It is not a function

Step-by-step explanation:

A function refers to a set of points/lines with this characteristic:

Each Y value has only one corresponding X value.

Meaning one X value cannot have multiple Y Values.

In this case, the X value of 2 has 2 different Y values, making it not a function.

Answer:

The answer will be the 3rd option, 12.8

Step-by-step explanation:

I'm gonna assume that since you copy and pasted the question, the equation is actually s - 0.2t^2

Now we just need to substitute the values with their respective ones.

20 - 0.2(6)^2

Now we just have to solve :)

20 - 0.2(6)^2

= 12.8

So the answer will be the 3rd option, 12.8

Answer:

Hello! The answer is x ≥ [tex]\frac{7}{2}[/tex].

Step-by-step explanation:

To solve this inequality, we have to get x by itself. To do so, we will rearrange the inequality. To do so, we will subtract 6x from both sides and add 3 to both sides:

8x - 3 ≥ 6x + 4

-6x +3  -6x  +3

----------------------

2x ≥ 7

Now, we have to get x by itself and divide both sides by 2 to do so:

2x ≥ 7

--     --

2      2

This leaves us with:

x ≥ [tex]\frac{7}{2}[/tex]

The required solution to the inequality 8x - 3 ≥6x + 4 is x ≥ 3.5.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

To solve the inequality, we want to isolate the variable x on one side of the inequality symbol.

8x - 3 ≥ 6x + 4

Subtract 6x from both sides:

2x - 3 ≥ 4

Add 3 to both sides:

2x ≥ 7

Divide both sides by 2:

x ≥ 7/2

Therefore, the solution to the inequality is x ≥ 3.5.

Answer:

y=2/3(x-3)^2+1

Step-by-step explanation:

The parent function of a parabola is y=x^2:

The transformation of this graph shows the parabola is shifted to the right 3 and up 1 so we apply that to our equation y=(x-3)^2+1

to solve the stretch factor:

y=a(x-3)^2+1

we can see when x=0 y=7 so we use this set

7=a(0-3)^2+1

7=a(-3)^2+1

-1            -1

6=9a

divide by 9

a=2/3

At the end of week 3, plant 1 is 0.6 inches taller than plant 2.

For plant 1, the height (in inches) equation as a function of the number of weeks is:

[tex]h_1(w) = 2.5 + \frac{4}{10}*w[/tex]

The height for w = 3 is:

[tex]h_1(3) = 2.5 + \frac{4}{10}*3 = 3.7[/tex]

So the height at the end of week 3 is 3.7 inches.

For plant 2 the equation is:

[tex]h_2(w) = 2.5 + \frac{1}{5}*w[/tex]

The height for w = 3.

[tex]h_2(3) = 2.5 + \frac{1}{5}*3 = 3.1[/tex]

So the height at the end of week 3 is 3.1 inches.

The difference is:

3.7 in - 3.1 in = 0.6 in

At the end of week 3, plant 1 is 0.6 inches taller than plant 2.

Step-by-step explanation:

To do this we can ask ourselves "What number multiplied three times by itself is _____?" In this case we have -27 and 81. We see that -3*-3*-3=-27. We also see that 3*3*3*3=81. This means that [tex]\sqrt[3]{-27}=-3,[/tex] and [tex]\sqrt[3]{81} = 3\sqrt[3]{3}.[/tex]

The fraction we get is [tex]\frac{-3}{3\sqrt[3]{3} }[/tex], and we can simplify to get [tex]-\frac{1}{\sqrt[3]{3}}[/tex].

Answer:

The side splitter theorem.

Step-by-step explanation:

You have a pair of parallel lines intersecting a triangle.

Because we can't divide by zero, csc(θ) is undefined when θ = 0°, so the correct option is A.

First, remember that:

[tex]csc(\theta) = 1/sin(\theta)[/tex]

And also remember that we can't divide by zero.

Then the function csc(θ) is undefined for the values of θ such that sin(θ) = 0.

We know that sin(0°) = 0.

Then csc(0°) is undefined. This means that the correct option is the first one.

Answer:

cheeseburger costs $1.25

Step-by-step explanation:

let x be the cost of a cheeseburger and y the cost of chilli and set up 2 simultaneous equations, that is

12x + 4y = 19.4 → (1)

8x + 6y = 16.6 → (2)

multiplying (1) by 6 and (2) by - 4 and adding the result will eliminate y

72x + 24y = 116.4 → (3)

- 32x - 24y = - 66.4 → (4)

add (3) and (4) term by term to eliminate y

40x + 0 = 50

40x = 50 ( divide both sides by 40 )

x = 1.25

the cost of a cheeseburger is $1.25

The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

0.1x + 0.25y = 19.9 and

x + y = 100

Let x = number of dimes

y = number of quarters

After solving the above system of equations by substitution method.

[tex]\rm \dfrac{398-5y}{2}+y=100[/tex]

y = 66

[tex]\rm x=\dfrac{398-5\cdot \:66}{2}[/tex]
