There are 6 dogs and 2 mice. Write a ratio for the number of ears to th number of paws. * 6:2 3 people are in a room. Write a ratio to represent the number of finger

Answers

Answer 1

each dog has 4 paws, then 6 dogs have 6*4 = 24 paws

each mouse has 4 paws, then 2 mice have 2*4 = 8 paws

Total number of paws: 24 + 8 = 32 paws

each dog has 2 ears, then 6 dogs have 6*2 = 12 ears

each mouse has 2 ears, then 2 mice have 2*2 = 4 ears

total number of ears: 12 + 4 = 16 ears

The ratio for the number of ears to the number of paws: 16/32 = 1/2 or 1:2

what should the height of the container be so as to minimize cost

Answers

Lets make a picture of our problem:

where h denotes the height of the box.

We know that the volume of a rectangular prism is

[tex]\begin{gathered} V=(4x)(x)(h) \\ V=4x^2h \end{gathered}[/tex]

Since the volume must be 8 cubic centimeters, we have

[tex]4x^2h=48[/tex]

Then, the height function is equal to

[tex]h=\frac{48}{4x^2}=\frac{12}{x^2}[/tex]

On the other hand, the function cost C is given by

[tex]C=1.80A_{\text{bottom}}+1.80A_{\text{top}}+2\times3.60A_{\text{side}1}+2\times3.60A_{\text{side}2}[/tex]

that is,

[tex]\begin{gathered} C=1.80\times4x^2+1.80\times4x^2+3.60(8xh+2xh) \\ C=3.60\times4x^2+3.60\times10xh \end{gathered}[/tex]

which gives

[tex]C=3.60(4x^2+10xh)[/tex]

By substituting the height result from above, we have

[tex]C=3.60(4x^2+10x(\frac{12}{x^2}))[/tex]

which gives

[tex]C=3.60(4x^2+\frac{120}{x})[/tex]

Now, in order to find minum cost, we need to find the first derivative of the function cost and equate it to zero. It yields,

[tex]\frac{dC}{dx}=3.60(8x-\frac{120}{x^2})=0[/tex]

which is equivalent to

[tex]\begin{gathered} 8x-\frac{120}{x^2}=0 \\ \text{then} \\ 8x=\frac{120}{x^2} \end{gathered}[/tex]

by moving x squared to the left hand side and the number 8 to the right hand side, we have

[tex]\begin{gathered} x^3=\frac{120}{8} \\ x^3=15 \\ \text{then} \\ x=\sqrt[3]{15} \\ x=2.4662 \end{gathered}[/tex]

Therefore, by substituting this value in the height function, we get

[tex]h=\frac{12}{2.4662^2}=1.9729[/tex]

therefore, by rounding to the neastest hundredth, the height which minimize the cost is equal to 1.97 cm

fine the slope of every line that is parallel to the line on the graph

Answers

Every parallel line would have the same slope because the slope formula is Δy/Δx and the difference would be the same, so the slope for the line with the given points would be -1/6, or roughly 0.167.

What is parallel lines?

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a fixed minimum distance between them and no contact or intersection are said to be parallel.

What is slope?

A line's steepness can be determined by looking at its slope. In mathematics, slope is determined by dividing the change in y by the change in x. Determine the coordinates of two points along the line that you choose. Find the difference between these two points' y-coordinates (rise). Find the difference between these two points' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.

Here the coordinates are (-6,0) and (0,-1)

ΔX = 0 – -6 = 6

ΔY = -1 – 0 = -1

Slope (m) =ΔY/ΔX

=-1/6

= -0.16666666666667

≈-0.167

The slope for the line with the given points would be -1/6, or roughly 0.167, because the slope formula is Δy/Δx and the difference would be the same for every parallel line.

Congruent Shapes

Two congruent shapes have the same size and shape, which means all of their side lengths are equal and all of their internal angles are congruent (have the same measure),

All of the rigid transformations map the original figure to a congruent figure. One of the transformations is the reflection.

The image shows two shapes SRQP and EDCB. They seem to have the same shape and size, but it must be proven by finding the appropriate transformation used.

Comparing the corresponding vertices we can find that out. For example, the coordinates of S are (-6,4) and the coordinates of E are (4,4). The x-coordinate of the midpoint between them is

xm = (-6+4)/2 = -1

Now analyze the points P(-8,2) and B(6,2). The x-coordinate of the midpoint is:

xm = (-8+6)/2 = -1

For the points R(-4,-6) and D(2,-6):

xm = (-4+2)/2 = -1

For the points Q(-9,-4) and D(8,-4):

xm = (-9+8)/2 = -0.5

Since this last pair of corresponding points don't have the same axis of symmetry as the others, the shapes don't have the same size and angles, thus they are not congruent

For both shapes to be congruent, the coordinates of Q should have been (-10,-4)

SOLUTION

Let us solve the simultaneous equation

[tex]\begin{gathered} -2x-y=0 \\ x-y=3 \end{gathered}[/tex]

using elimination

To eliminate, we must decide which of the variables, x or y is easier to eliminate. The variable you must eliminate must be the same and have different sign. Looking above, it is easier to eliminate y because we have 1y above and 1y below. But to eliminate the y's, one must be +y and the other -y. So that +y -y becomes zero.

So to make the y's different, I will multiply the second equation by a -1. This becomes

[tex]\begin{gathered} -2x-y=0 \\ (-1)x-y=3 \\ -2x-y=0 \\ -x+y=-3 \end{gathered}[/tex]

So, now we can eliminate y, doing this we have

[tex]\begin{gathered} -2x-x=-3x \\ -y+y=0 \\ 0-3=-3 \\ \text{This becomes } \\ -3x=-3 \\ x=\frac{-3}{-3} \\ x=1 \end{gathered}[/tex]

Now, to get y, we put x = 1 into any of the equations, Using equation 1, we have

[tex]\begin{gathered} -2x-y=0 \\ -2(1)-y=0 \\ -2-y=0 \\ \text{moving -y to the other side } \\ y=-2 \end{gathered}[/tex]

So, x = 1 and y = -2

Using substitution, we make y or x the subject in any of the equations. Looking at this, It is easier to do this using equation 2. From equation 2,

[tex]\begin{gathered} x-y=3 \\ \text{making y the subject we have } \\ y=x-3 \end{gathered}[/tex]

Now, we will put y = x - 3 into the other equation, which is equation 1, we have

[tex]\begin{gathered} -2x-y=0 \\ -2x-(x-3)=0 \\ -2x-x+3=0 \\ -2x-1x+3=0 \\ -3x+3=0 \\ -3x=-3 \\ x=\frac{-3}{-3} \\ x=1 \end{gathered}[/tex]

So, substituting x for 1 into equation 1, we have

[tex]\begin{gathered} -2x-y=0 \\ -2(1)-y=0 \\ -2\times1-y=0 \\ -2-y=0 \\ y=-2 \end{gathered}[/tex]

Substituting x for 1 into equation 2, we have

From the diagram given in the question, we are asked to find the missing length indicated.

We can see from the diagram that the right triangles are similar, so the ratio of hypotenuse to short leg is the same for all.

So,

x/900 = (1600 + 900)/x

Let's cross multiply:

x² = 900(2500)

let's take square of both sides:

x = √(900) * √(2500)

x = 30(50)

x = 30 * 50

x = 1500

Therefore, the missing length is 1500

A rectangular athletic field is twice as long as it is wide if the perimeter of the athletic field is 360 yards what are its dimensions. The width isThe length is

Answers

Step 1. We will start by making a diagram of the situation.

Since the length of the rectangle is twice the width, if we call the width x, then the length will be 2x as shown in the diagram:

Step 2. One thing that we know about the rectangle is its perimeter:

[tex]\text{Perimeter}\longrightarrow360\text{yd}[/tex]

This perimeter has to be the result of the sum of all of the sides of the rectangle:

[tex]x+x+2x+2x=360[/tex]

Step 3. Solve the previous equation for x.

In order to solve for x, the first step is to combine the like terms on the left-hand side:

[tex]6x=360[/tex]

The second step to solve for x is to divide both sides of the equation by 6:

[tex]\frac{6x}{6}=\frac{360}{6}[/tex]

Simplifying:

[tex]x=60[/tex]

Step 4. Remember from the diagram from step 1, that x was the width of the rectangle:

[tex]\text{width}\longrightarrow x\longrightarrow60yd[/tex]

and the length was 2x, so we multiply the result for the with by 2:

[tex]\text{length}\longrightarrow2x=2(60)=120\longrightarrow120yd[/tex]

And these are the values for the width and the length.

Answer:

Where p' is the sample proportion, z is the z-score related to the 95% level of confidence, n is the size of the sample and p is the population proportion.

Now, we can calculate p' as the division of the number of voters of favor approval by the total number of voters.

[tex]p^{\prime}=\frac{408}{865}=0.4717[/tex]

Additionally, n = 865 and z = 1.96 for a 95% level of confidence. So, replacing the values, we get:

In the 1st generation, there are 6 rabbits in a forest. Every generation after that, the rabbit population triples. This sequence represents the numbers of rabbits for the first few generations: 6, 18, 54, What is the explicit formula for the number of rabbits in generation n?

Answers

You have the following sequence for the population of the rabbits:

The explicit formula for the previous sequence is obtained by considering the values of n (1,2,3,..) for the first terms of the sequence.

You can observe that the explicit formula is:

a(n) = 6·3^(n - 1)

in fact, for n=1,2,3 the result is:

a(1) = 6·3^(1 - 1) = 6·3^0 = 6

a(2) = 6·3^(2 - 1) = 6·3^1 = 18

a(3) = 6·3^(3 - 1) = 6·3^2 = 6·9 = 54

which is consistent with the given sequence 6, 18, 54, ...

Step-by-step explanation:

Complex numbers

(x + yi) +6i = 2

Subtract 6i from each side

(x + yi) +6i -6i = 2-6i

Answers

Solution:

Consider the following expression:

[tex]\frac{8!4!}{7!2!}[/tex]

Remember that The factorial function is defined by the product:

[tex]n!\text{ = }1\cdot2\cdot3\cdot\cdot\cdot\cdot\cdot\cdot(n-2)\cdot(n-1)\cdot n[/tex]

thus, according to this definition, the given expression can be expressed as:

[tex]\frac{8!4!}{7!2!}\text{ = }\frac{(1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot7\cdot8)\text{ (}1\cdot2\cdot3\cdot4\text{)}}{(1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot7)(1\cdot2)}[/tex]

now, simplifying the previous expression we obtain:

[tex]\text{= }(8)\text{ (}3\cdot4\text{) = }96[/tex]

we can conclude that the correct answer is:

[tex]\text{ }96[/tex]
