c. A vendor at a street fair sells popcorn in cones, all of height 9 inches. The sharing-size cone has 3 times the radius of the skinny-size cone. About how many times more popcorn does the sharing cone hold than the skinny cone?

Answers

Answer:

Sharing cone holds 9 times more popcorn than a skinny cone.

Step-by-step explanation:

Height of each cone = 9 inches

Radius of the sharing size cone = 3 times radius of the skinny size cone

Let the radius of skinny size cone = r

Then radius of the sharing size cone = 3r

Volume of the sharing size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]

                                                     = [tex]\frac{1}{3}(\pi )(3r)^{2}(9)[/tex]

                                                     = 27πr²

Volume of the skinny size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]

                                                       = [tex]\frac{1}{3}(\pi )(r)^{2}(9)[/tex]

                                                       = 3πr²

Ratio of the volumes = [tex]\frac{\text{Volume of sharing size cone}}{\text{Volume of skinny size cone}}[/tex]

                                   = [tex]\frac{27\pi r^{2}}{3\pi r^{2} }[/tex]

                                   = 9

Therefore, sharing cone holds 9 times more popcorn than a skinny cone.

A six-sided number cube is rolled two times. What is the probability of rolling a 4 both times?

Answers

Answer: 1/36

Explanation: In this problem, we're given that a number cube is rolled twice and we're asked to find the probability of rolling a 4 and a 4.

It's important to understand that the two rolls of the number cube are independent events because the results of one role does not affect the results of the other roll.

To find the probability of two independent events, we first find the probability of each event, then we multiply the probabilities.

So let's first find the probability of rolling

a 4 with our first role of the number cube.

We can find the probability of an event using the following ratio:

number of favorable outcomes over total number of outcomes

Since there's only one way to roll a 4 and there are six possible outcomes 1, 2, 3, 4, 5, and 6, the probability of rolling a 4 is 1/6.

Next, we find the probability of rolling a 4 with our second roll of the number cube, which would also be 1/6.

Now, to find the probability of rolling a 4 and a 4,

we simply multiply the probabilities.

Now multiply 1/6 x 1/6 by multiplying across the top and bottom.

This gives us 1/36.

So the probability or likelihood of rolling a 4 two times in a row is 1/36.

Step-by-step explanation:

Total pets are:

cats + dogs + snakes + rabbits + birds

4 + 7 + 1 + 3 + 5 = 20 pets available for adoption

To find probability dived the number available of each  pet by the total number of pets available.

A company is designing a new cylindrical water bottle. The volume of the bottle will be 121 cmcubed. The height of the water bottle is 7.6 cm. What is the radius of the water​ bottle? Use 3.14 for pi.

Answers

Answer:

The radius of the water bottle is 2.25 cm

Step-by-step explanation:

The water bottle is said to be cylindrical, so its volume can be expressed as the volume of a cylinder.

Volume of a cylinder V = πr^2 h

Where;

h = height

r = radius

Making the radius the subject of formula;

r^2 = V/πh

r = √(V/πh)

Given:

Volume V = 121 cm^3

height h = 7.6 cm

π = 3.14

Substituting the given values;

r = √(121/(3.14×7.6))

r = 2.25 cm

The radius of the water bottle is 2.25 cm

What is the slope-intercept equation of the line below? ​

Answers

Answer:

y = -x-2

Step-by-step explanation:

We are given a slope of -1 and the y intercept of -2

The slope intercept form of the equation for a line is

y = mx+b

where m is the slope and b is the y intercept

y = -1x +-2

y = -x-2

Answer:

y=-x -2

Step-by-step explanation:

Slope-intercept form is

y=mx+b

where m is the slope and b is the y-intercept

We know that the slope is -1. We also know that the y-intercept is (0, -2). For this form, we can disregard the 0, and say the y intercept is just -2.

So, m is -1, and b is -2. Substitute the values into the equation.

y=mx+b

y=-1x+-2

Simplify

y= -x -2

This is the equation of the line in slope-intercept form.

[tex]d.\ x=-i, i, 3 \sqrt{5}\ or\ -3 \sqrt{5}[/tex]

Step-by-step explanation:

The given equation has a degree 4  (Highest power of [tex]x[/tex]):

[tex]x^4-44x^2-45=0[/tex] is the given equation which can be written as:

[tex](x^2)^2-44x^2-45=0 ...... (1)[/tex]

Let [tex]t=x^{2}[/tex] and putting it in equation (1):

[tex]t^2-44t-45=0 \\[/tex]

Solving the above quadratic equation in variable [tex]t[/tex]:

[tex]\Rightarrow t^2-45t+t-45=0 \\\Rightarrow t(t-45)+1(t-45)=0\\\Rightarrow (t+1)(t-45)=0\\\Rightarrow t =-1\ or\ 45[/tex]

We know that [tex]t=x^{2}[/tex]

So, [tex]x^{2} =-1\ or\ x^{2}= 45[/tex]

1. Solving [tex]x^{2} =-1[/tex]

[tex]\Rightarrow x = +\sqrt{-1}\ or\ -\sqrt{-1}\\\Rightarrow x = i\ or\ -i[/tex]

2. Solving [tex]x^{2} =45[/tex]

[tex]\Rightarrow x = +\sqrt{45}\ or\ -\sqrt{45}\\\Rightarrow x = 3\sqrt{5}\ or\ -3\sqrt{5}[/tex]
