8 congruent spheres are packed into a cube with
edge length x so that each sphere is tangent to 3
faces of the cube and 3 other spheres as shown.
what is the ratio of the total volume of the
spheres of the volume of the cube?

Answers

Answer:

Ratio of the volumes of the spheres and cube = 0.523

Step-by-step explanation:

From the figure attached,

Diameter of one sphere = Half of the measure of one side of the cube

                                        = [tex]\frac{x}{2}[/tex]

Radius of the sphere = [tex]\frac{\frac{x}{2}}{2}[/tex]

                                   = [tex]\frac{x}{4}[/tex]

Volume of a cube is given by the formula,

V = [tex]\frac{4}{3}\pi r^{3}[/tex]

Therefore, volume of one sphere = [tex]\frac{4}{3}\pi (\frac{x}{4})^{3}[/tex]

                                                        = [tex]\frac{x^3\pi}{48}[/tex]

Volume of 8 spheres = [tex]8\times \frac{x^3\pi}{48}[/tex]

                                   = [tex]\frac{x^3\pi}{6}[/tex]

Volume of a cube = (side)³

                              = [tex]x^3[/tex]

Ratio of the volumes of the sphere and cube = [tex]\frac{\frac{\pi x^3}{6} }{x^3}[/tex]

                                                                              = [tex]\frac{\pi}{6}[/tex]

                                                                              ≈ 0.523

Step-by-step explanation:

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms.

f(x) = 6x2 + x − 12

A. quadratic function; quadratic term: −12x2; linear term: −6x; constant term: −12

B. linear function; linear term: x; constant term: −12

C. linear function; linear term: 6x2; constant term: −12

D. quadratic function; quadratic term: 6x2; linear term: x; constant term: −12

Answers

Answer:

D

Step-by-step explanation:

The function f(x) = 6x2 +x -12 is a quadratic since the highest degree polynomial term is 2. So that eliminates B and C. Option A is incorrect because the quadratic term is 6 not double the constant. There for the correct choice is D because the function is a quadratic and the quadratic term is 6x2, the linear term is x and the constant term is -12.

If the equation of a circle is (x + 4)2 + (y - 612 = 25, its center point is

(4,6)
(4,-6)

Answers

Answer:

Center point: [tex](-4,6)[/tex]

Radius: [tex]r=5[/tex]

Step-by-step explanation:

The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center point of the circle and [tex]r[/tex] is the radius of the circle.

Given our equation [tex](x+4)^2+(y-6)^2=25[/tex], we can see that [tex](h,k)[/tex] is [tex](-4,6)[/tex] and since [tex]r^2=25[/tex], our radius is  [tex]r=\sqrt{r^{2} } =\sqrt{25} = 5[/tex]

Therefore, the center point is [tex](-4,6)[/tex] and the radius is [tex]r=5[/tex]

You and two of your friends go to eat pizza

together. There are two deals:

1. 10% off of 1 pizza )

2. 30% off of 3 pizzas

Do you want to each pay separately and get

10% off of your bill, or do you want to split the

bill 3 ways and get 30% off of 3 pizzas?

Write a response that convinces your teacher

Answers

Answer:

The second deal offers a lower cost for the three friends.

Step-by-step explanation:

Let consider that each pizza has a price [tex]c_{o}[/tex]. Now, we proceed to check the total cost for each case, the better choice is whose total cost after discounts is the lowest.

Case 1 - 10 % off of 1 pizza (Split costs and buy 3 pizzas separately)

[tex]C = 0.9\cdot C_{o} + 0.9\cdot C_{o} + 0.9\cdot C_{o}[/tex]

[tex]C = 2.7\cdot C_{o}[/tex]

The cost for each person is:

[tex]c = \frac{C}{3}[/tex]

[tex]c = 0.9\cdot C_{o}[/tex]

Case 2 - 30 % off of 3 pizzas (Split costs and buy 3 pizzas in a row)

[tex]C = 0.7\cdot (3\cdot C_{o})[/tex]

[tex]C_{o} = 2.1\cdot C_{o}[/tex]

The cost for each person is:

[tex]c = \frac{C}{3}[/tex]

[tex]c = 0.7\cdot C_{o}[/tex]

The second deal offers a lower cost for the three friends.

Renee can sew a 25-square-foot quilt in 16 hours. Genera can sew the same size quilt in 12 hours. How long would it take them to sew the quilt working together? Rate (Quilts per Hour) Time (Hours) Fraction Completed Renee One-sixteenth x Genera One-twelfth x 6 hours 6 and six-sevenths hours 8 and six-sevenths hours 28 hours

This is calculated as:

1/ number of hours for Renee + 1/ number of hours for Geneva = 1/ Total number of hours that they can do it together

= 1/16 + 1/12 = 1/T

Lowest common denominator = 192

= 12 + 16/192 = 1/T

Use the vertical line test to determine whether y is a function of x

Answers

Answer:

Not a function of x

Step-by-step explanation:

A vertical line intersects the graph twice, which immediately tells us that y is not a function of x here.  If y were a function, the vertical line would intersect the graph in only one place.

No, A vertical line intersects the graph doubled, which instantly tells us that y exists not a function of x here. If y existed a function, the vertical line would intersect the graph in just one area.

What is Vertical line test?

If a vertical line can be drawn to connect the graph of a function in more than one place, then stands NOT a function. If it exists not feasible to draw a vertical line to touch the graph of a function in more than one place, then y exists as a function of x.

No, A vertical line intersects the graph doubled, which instantly tells us that y exists not a function of x here. If y existed a function, the vertical line would intersect the graph in just one area.

Amount of paper:

Answers

Answer:

Amount of paper need = 140 cm²

Step-by-step explanation:

Given:

Length of rectangular prism = 5 cm

Width of rectangular prism = 5 cm

Height of rectangular prism = 4 cm

Base of triangular side = 5cm

Height of triangular side = 6 cm

Find:

Amount of paper need

Computation:

Amount of paper need = Curved surface area of rectangular prism +  Curved surface area of square pyramid

Amount of paper need = 2h(l + b) + 4[Area of triangle]

Amount of paper need = 2h(l + b) + 4[(1/2)(b)(h)]

Amount of paper need = (2)(4)(5 + 5) + 2[(5)(6)]

Amount of paper need = (8)(10) + 2[30]

Amount of paper need = 80 + 60

Amount of paper need = 140 cm²

Parts for an automobile repair cost ​$173. The mechanic charges ​$32 per hour. If a person receives an estimate for at least ​$253 and at most ​$285 for fixing the​ car, what is the time interval that the mechanic will be working on the​ job?

Answers

Answer:

58

Step-by-step explanation:

The time interval for the mechanic for this job is at least 2 hours and 30 minutes or at most 3 hours and 30 minutes.

What is at least and at most concept ?

At least means lower limit of a given contrast and at most means higher limit of a given contrast.

According to the given question parts for an automobile repair cost ​173 dollars and the mechanic charges 32 dollars per hour.

Given the person receives a cost of at least 253 dollars.

∴ The mechanic's total rate is ( 253 - 173 ) dollars which is = 80 dollars.

Also given the mechanic charges 32 dollars per hour so the time mechanic work for is at least (80/32) hours which is = 2.5 hours or 2 hours and 30 minutes.

In the later case when the owner receives a bill of 285 dollars the total rate of mechanic is

= ( 285 - 173 ) dollars.

= 112 dollars.

So, the mechanic have worked for (112/32) hours which is

= 3.5 hours or 3 hours and 30 minutes.
