If two sides of a triangle measure 12 and 7, which cannot be the perimeter of the triangle

Answer:  The correct option is (B). Its image is attached below.

Step-by-step explanation:  We are given to select the graph that represents the circle with equation as follows:

[tex]x^2+y^2=9~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that the standard equation of a circle with center at the point (h, k) and radius r units is given by

[tex](x-h)^2+(y-k)^2=r^2.[/tex]

From equation (i), we have

[tex]x^2+y^2=9\\\\\Rightarrow(x-0)^2+(y-0)^2=3^2.[/tex]

Comparing the above equation with the standard equation of a circle, we get

Center, (h, k) = (0, 0) and radius, r = 3 units.

We draw the graph of the circle with center at the origin (0, 0) and radius 3 units in the attached figure below.

We see that the graph of the circle is same as the one provided in option (B).

Thus, option (B) is CORRECT.

x = hours

car 1 left an hour before car 2 so you have 55(x+1)

car 2 = 75x

 add them together to equal miles driven:

55(x+1) + 75x = 380

55x+55 + 75x = 380

 combine like terms:

130x+55 = 380

 subtract 55 from each side:

130x = 325

divide both sides by 130

x = 325 /130 = 2.5

x = 2.5 hours

 so 2.5 hours

1000 chips minimize the production cost in the given equation, and the minimum cost for producing these chips is $20.

To find the number of chips that minimizes the cost in the given quadratic equation, y = 0.000015x^2 - 0.03x + 35, we can use the vertex formula for a parabola, which is derived from the general quadratic equation.

The general form of a quadratic equation is y = ax^2 + bx + c, and the x-coordinate of the vertex, which gives us the number of chips that minimizes the cost, can be found using x = -b/(2a). For our equation, a = 0.000015 and b = -0.03.

Substituting the values of a and b into the vertex formula:

Now, we plug this value back into the original equation to find the minimum cost:

This gives us the minimum cost and the number of chips that lead to this cost. Therefore, 1000 chips minimize the cost, and the minimum cost for producing these chips is $20.

There are multiple pairs of numbers that multiply to 108, such as 1 × 108, 2 × 54, 3 × 36, 4 × 27, 6 × 18, and 9 × 12. Therefore, any pair of these factors will correctly answer the question.

To determine what times what equals 108, we need to identify the factors of 108.

1 × 108 = 108

2 × 54 = 108

3 × 36 = 108

4 × 27 = 108

6 × 18 = 108

9 × 12 = 108

There are multiple pairs of numbers that, when multiplied together, equal 108. Therefore, any of these factor pairs are valid answers to the question.

For example, 9 times 12 or 6 times 18 are pairs that satisfy this condition.

Answer:

D. ; each drink cost $3

Step-by-step explanation:

Given that Elizabeth bought 4 drinks and some nachos.

Total amount spent = [tex]18[/tex]$

She can buy only in integers the drinks i.e.1,2,or 3

Nachos also she can buy 1,2...

If x is the no of nachos and d the cost of drink, we get

[tex]6x+4d=18[/tex]

If x=1, d =3

x=2, d = 1.50

d=3, d=0 (which is not possible)

Hence d can take values either as 3 or 1.50

Out of the options given 3 is only there.

Answer:

[tex]7.4\times 10^{-3}\ mm[/tex]

Step-by-step explanation:

Actual measurement of diameter of a blood cell is 6 to 8 μm

Let diameter be d

[tex]1\mu m=10^{-6}\ m[/tex]

[tex]6\times 10^{-6}\ m\leq d\leq 8\times 10^{-6}\ m[/tex]

Now we check the given measurement between the range.

Change into meter. As we know 1000 mm = 1 m or 1 mm = 10⁻³ m

[tex]7.4\times 10^{-3}\times 10^{-3}\ m[/tex]

[tex]7.4\times 10^{-6}\ m[/tex]

[tex]7.4\times 10^{3}\times 10^{-3}\ m[/tex]

[tex]7.4\ m[/tex]

So, [tex]7.4\times 10^{-6}\ m[/tex] lie between [tex]6\times 10^{-6}\ m\leq d\leq 8\times 10^{-6}\ m[/tex]

Hence, [tex]7.4\times 10^{-6}\ m[/tex] more reasonable measurement of diameter of blood cell because it lies between range of diameter of blood cell.

Answer:

AA' + BB' + CC' + DD' +EE' = 27.5 inches

Step-by-step explanation:

A translation moves all points of a figure the same distance in the same direction. If line segment YZ is 5.5 inches long, then the distance between original point A and translated point A' would be 5.5 inches. That is also valid to the other points. So, length of AA' = BB' = CC' = DD' = EE' = 5.5 inches. In consequence, AA' + BB' + CC' + DD' +EE' = 5*5.5 inches = 27.5 inches

The statement fourth "You have at least $1000" is correct if you have a ruby, then it you have at least $1000.

Legal syllogism is a legitimate concept that deals with the law and how it is applied, specifically a type of argument that uses deductive reasoning to determine whether a given act is legal.

We have:

Assume that you own a ruby. Apply the law of detachment to the following conditional statement:

The statement is:

If you have a ruby, then it you have at least $1000.

As we know, the law of detachment, we must let go of attachment to both the desired end and all possible routes to get there in order to actualize our wants.

Thus, the statement fourth "You have at least $1000" is correct if you have a ruby, then it you have at least $1000.

Given the statement 'If you have a ruby, then you have at least $1000.' and the fact that you have a ruby, the Law of Detachment leads to the conclusion 'You have at least $1000.'

The Law of Detachment (also known as Modus Ponens) in logic says that if a conditional statement ('if p then q') is true and the first part of the statement (p) is true, then the second part of the statement (q) is true. Let's apply it to your statement.

The original statement is 'If you have a ruby, then you have at least $1000.' You confirmed the first part 'You have a ruby.' So, according to the Law of Detachment, the resulting correct statement would be 'You have at least $1000.' The other statements about selling or someone buying the ruby are irrelevant to the Law of Detachment.

The volume of the cone is one-third of the volume of the cylinder which is equal to the product of area of the base and the height. The equation is,

    V = (1/3)(pi)(r^2)h         

Dividing both sides of the equation by (1/3)(pi)(h) will give us,

  3V/(pi)(h) = r^2

Taking the square-root of both sides,

  r = sqrt(3V/(pi)(h))

Answer:

[tex]r = \sqrt{\displaystyle\frac{3V}{h\pi}}[/tex]

Step-by-step explanation:

We are given the following information in the question.

Using the formula for volume of cone, we have to express r in terms of V, h and pi.

Formula:

[tex]\text{Volume of cone, V} = \displaystyle\frac{1}{3}\pi r^2 h\\\\\text{where r is the radius of cone, h is the height of radius}[/tex]

Now, we have to evaluate r, the radius of cone.

Rearranging the terms, we have,

Working:

[tex]V = \displaystyle\frac{1}{3}\pi r^2 h\\\\r^2 = \frac{3\times V}{\pi\times h}\\\\r^2 = \frac{3V}{h\pi}\\\\r = \sqrt{\frac{3V}{h\pi}}[/tex].

Thus, r in form of V, h and pi can be written as:

[tex]r = \sqrt{\displaystyle\frac{3V}{h\pi}}[/tex]

The number of bags of sand that Jack need to fill the box completely are:

                                        2

The length(l) of the sand box is 3 feet, width(w) is 6 inches, and height(h) is 2.4 inches.

Also,

1 foot=12 inches

This means that:

1 inch=1/12 foot

i.e.

6 inches=0.5 feet

i.e.

w=0.5 feet

and

h=2.4 inches

i.e.  h=0.2 feet

Now, we find the volume of the rectangular box.

The volume of the rectangular box is given by:

Volume=lwh

Hence,

Volume=3×0.5×0.2

i.e.

Volume=0.3 cubic feet.

Also, the volume of one bag of sand= 0.15 cubic feet

This means that the number of bags of sand that will fill the box completely is:

(Volume of rectangular box) / (Volume of one bag of sand)

=   0.3/0.15

=2

Hence, number of bags =2
