Samantha gathered the following information on a given day at the dog park.

• There are 3232 dogs playing at the dog park.
• 1515 of the dogs are puppies.
• 1111 of the dogs are not puppies and have long hair.
• There are 66 more dogs that have long hair than dogs that do not have long hair.

Fill in the table completely to represent Samantha's data.

Step-by-step explanation:

the extreme values of a function happen at the zeros of the first derivation of that function.

f(t) = -16t² + 72t

f'(t) = -2×16t + 72 = -32t + 72

0 = -32t + 72

32t = 72

t = 72/32 = 2.25 seconds

f(2.25) = -16(2.25)² + 72×2.25 = -16×5.0625 + 72×2.25 =

= -81 + 162 = 81 ft

so, the rocket reaches its maximum height of 81 ft after 2.25 seconds of flight.

Answer:

If Its 7 in diameter than the answer is 21.98 if it is radius than it is 153.86

Step-by-step explanation:

Answer:

Solution:

Radius of a circle = 7 in

We know that

Circumference of a circle = 2πrSubstituting the values

= 2 × π × 7

= 14π

= 43.9823 ≈ 43.98 in

Therefore, the circumference of a circle is 43.98 in.

Step-by-step explanation:

The hydroxide ion concentration in a solution of nh3 with a poh of 4.65 is 2.2387×10⁻⁵ M.

The pH scale, which originally stood for "potential of hydrogen," is used to describe the acidity or basicity of aqueous solutions. The pH of acidic solutions is lower than that of basic or alkaline solutions.

Hydronium ions concentration of the solution with a pH value of 4.65.

[tex]pH = -\rm log[H_3O^+]\\\\4.65 = -log[H_3O^+]\\\\\text{Taking Antilog}\\\\10^{-4.65}=[H_3O^+]\\[/tex]

[tex][H_3O^+] = 2.2387 \times 10^{-5} M[/tex]

Now, we know that the Hydroxide ions concentration of the solution with pOH value of 4.65. Therefore,

[tex]pOH = -\rm log[OH^-]\\\\4.65 = -log[OH^-]\\\\\text{Taking Antilog}\\\\10^{-4.65}=[OH^-][/tex]

[tex][OH^-]=2.2387 \times 10^{-5}\ M[/tex]

Hence, the hydroxide ion concentration in a solution of nh3 with a poh of 4.65 is 2.2387×10⁻⁵ M.

Z-score of given data comes to be 4.84.

It is given that:

Mean price of a prom dress μ= $195

Standard deviation σ= 12

Mean of price spent on prom dress out of 20 people X= $208

Sample size n= 20

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

Z-score = (X-μ)/(σ/√n)

Where, X = observed value

μ= mean

σ = standard deviation

n =sample size

Z-score of above data = (208-195)/(12/√20)

Z-score = 4.84

Therefore, the Z-score of the given data comes to be 4.84.

Answer:

7 times x = t

Step-by-step explanation:

if your buying 3 dozen of donuts, the total cost would be by doing 7x3

Solution:

It should be noted:

Let's reread the sentence carefully.

Eric sells donuts for $7    per dozen.

                                   ↥           ↥

                                  $7     1 dozen

The equation created: $7 = 1 dozen

If x dozen doughnuts were sold, equation: $7x = t = x dozen

Thus, the equation that can determine the total cost, t, for x dozen of donuts is $7x = t.

Any straight line segment can be extended indefinitely and straight line segment can be drawn between any two points can apply. Therefore, options A and D are the correct answers.

"Euclidean geometry is the study of plane and solid figures on the basis of axioms and theorems employed by the Greek mathematician Euclid"

As per the five basic postulates of Euclidean geometry

A straight line can be drawn from any point to another point.

A terminated line can be further produced indefinitely.

A circle can be drawn with any Centre and any radius.

All right angles are equal to one another.

If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles , then the two lines inevitably must intersect each other on that side if extended far enough.

Therefore, options A and D are the correct answers.

Step-by-step explanation:

Rectangle: 6*15=90

Inner Trapezoid: 6*4=24

Triangles: 4*2=8/2=4*2=8

Answer:

Question (a)

Surface area of a cube = [tex]6x^2[/tex]   (where [tex]x[/tex] is an edge length)

⇒ surface area = 6 × 3²

                         = 6 × 3 × 3

                         = 6 × 9

                         = 54 in²

Volume of a cube = [tex]x^3[/tex]   (where [tex]x[/tex] is an edge length)

⇒ volume = 3³

                 = 3 × 3 × 3

                 = 27 in³

Question (b)

To find the area of a dilated figure, simply multiply the original area by the scale factor squared:

Surface area = [tex]6x^2[/tex] × sf²  

                      = 54 × 0.5²

                      = 13.5 in²

To find the volume of a dilated figure, simply multiply the original volume by the scale factor cubed:

Surface area = [tex]x^3[/tex] × sf³

                      = 27 × 0.5³

                      = 3.375 in³

Answer: I think he gets 1/2 of something

Step-by-step explanation:

The number that needs to be added to the equation [tex]x^{2} +4x+3[/tex] will be 1

Given equation is  [tex]x^{2} +4x+3[/tex]

Now by adding 1 to the equation  [tex]x^{2} +4x+3[/tex] we get

[tex]x^{2} +4x+3+1=x^{2} +4x+4[/tex]

[tex]x^{2} +2x+2x+4[/tex]

Now by splitting the equation

[tex]x(x+2)+2(x+2)[/tex]

[tex](x+2)(x+2)[/tex]

[tex](x+2)^{2}[/tex]

Thus the number that needs to be added to the equation [tex]x^{2} +4x+3[/tex] will be 1
