can someone help me please​

Answer:

The answer is below

Step-by-step explanation:

The question is not correct, the correct question is:

The regional manager of a chain of department stores created the following stem-and-leaf plot showing the number of pairs of boots at each of the stores:

I 0 I

I 1 I 7 8

I 2 I 0 5 8

I 3 I 4 4 7 8

I 4 I 0

I 5 I

I 6 I

How many department stores have more than 60 pairs of boots

Answer:

The stem and leaf plot is a table which is used to represent a value with the first and other digit as the stem while the last digit is the leaf.

From the table attached, the first column is the stem and the remaining column are the leafs. Therefore from the table, below are the pairs of boots in different stores:

17, 18, 20, 25, 28, 34, 34, 37, 38 and 40.

All the store have fewer than 60 boots. This means that the number of stores with more than 60 pairs of boots is 0

Answer: yes

Step-by-step explanation:

adding 50 40 30 20 10 and 0 gets you 150 so 2nd place gets 40

Answer:

Step-by-step explanation:

[tex]v=\dfrac st\quad\implies\quad t=\dfrac sv[/tex]

s = 2 km

t - time of run

v - speed of running

Batman:

v = 3km/min

[tex]t = \dfrac{2\,min}{3\,\frac{km}{min}}=2\,km\cdot\dfrac{min}{3\,km}=\dfrac23\,min = \dfrac23\cdot 60\,s=40\, s[/tex]

The Bionic Woman:

v = 5 km/min

[tex]t = \dfrac{2\,min}{5\,\frac{km}{min}}=2\,km\cdot\dfrac{min}{5\,km}=\dfrac25\,min = \dfrac25\cdot 60\,s=24\, s[/tex]

time from Batman's start: 24 s + 12 s = 36 s

40 - 36 = 4

C) Translation 8 units to the right

Step-by-step explanation:

The function h(x) = 12·x⁸ + 49 is an even function

However a translation 8 units to the right would yield the following function;

h(x) = 12 × (x+ 8)⁸ + 49 = 12x⁸ + 768x⁷ + 21504x⁶ + 344064x⁵ + 3440640x⁴ + 22020096x³ + 88080384x² + 201326592x + 201326641

For h(1) = 516560701

Also h(-x) = 12 × (-x+ 8)⁸ + 49 = 12x⁸ - 768x⁷ + 21504x⁶ - 344064x⁵ + 3440640x⁴ - 22020096x³ + 88080384x² - 201326592x + 201326641

For h(-1) = 69177661

Therefore h(x) ≠ h(-x) after the translation 8 units to the right and the function is neither even nor odd.

Answer: 13.5π≈42.41

Step-by-step explanation:

Basically it is asking for the circumference of this cylinder.

#1 Find the circumference of the circle base

Formula to use: 2πr

2πr=2π(1.5)=3π

---------------------------

#2 Find the area of the circle base

Formula to use: πr²

πr²=π(1.5)²=2.25π

--------------------------

#3 Find the area of body of the cylinder

Formula to use: lw

300cm=3m

l (length)= 3π (since the body of the cylinder the basing on the circumference of the circle base)

w (width)= 3

lw=3π×3m=9π

#4 Add all of them together

There are 2 base and one body

2.25π×2+9π=13.5π

Answer/Step-by-step explanation:

3.a. length of AC.

Hypotenuse = AC

Opposite side to 60° = 7

Therefore, [tex] sin(60) = \frac{7}{AC} [/tex]

[tex] AC*sin(60) = \frac{7}{AC}*AC [/tex]

[tex] AC*sin(60) = 7 [/tex]

[tex] AC = \frac{7}{sin(60)} [/tex]

[tex] AC = 8.1 [/tex] (to nearest tenth)

b. Length of BC

Hypotenuse = BC

Opposite side to 50° = 7

Therefore, [tex] sin(50) = \frac{7}{BC} [/tex]

[tex] BC*sin(50) = \frac{7}{BC}*AC [/tex]

[tex] BC*sin(50) = 7 [/tex]

[tex] BC = \frac{7}{sin(50)} [/tex]

[tex] BC = 9.1 [/tex] (to nearest tenth)

c. Length of AB

Use the law of sines to find AB

[tex] \frac{BC}{sin(A)} = \frac{AB}{sin(C}} [/tex]

m<C = 180 - (60 + 50) (sum of angles in a triangle) = 70°

m<A = 60°

BC = 9.1

AB = ?

[tex] \frac{9.1}{sin(60)} = \frac{AB}{sin(70)} [/tex]

Cross multiply

[tex] 9.1*sin(70) = AB*sin(60) [/tex]

Divide both sides by sin(60)

[tex]\frac{9.1*sin(70)}{sin(60)} = \frac{AB*sin(60)}{sin(60)}[/tex]

[tex]\frac{9.1*sin(70)}{sin(60)} = AB[/tex]

[tex] 9.9 = AB [/tex] (nearest tenth)

[tex] AB = 9.9 [/tex]

Let x be the no.of square feet for landscaping

Company A

Monthly consulting fee = $250

Cost of landscaping of 1 sq.feet = $10

Cost of landscaping of x sq.feet = $10x

So, Total charge by company A = 250+10x  ---1

Company B

Monthly consulting fee = $90

Cost of landscaping of 1 sq.feet = $12

Cost of landscaping of x sq.feet = $12x

So, Total charge by company B = 90+12x   ---2

Now we are supposed to find  how many square feet of landscaping will the two companies charge the same amount

So, Equate 1 and 2

[tex]250+10x=90+12x\\160=2x\\80=x[/tex]

So, the two companies charge the same amount for 80 sq.feet

Total charge by company A for 80 sq.feet = 250+10(80)= $1050

Total charge by company B for 80 sq.feet = 90+12(90)=$1170

Answer:

$94.05

Step-by-step explanation:

Original price of jeans=$95

Discount=10%

New price=(100% - 10%) of $95

=90% × 95

=90/100 × 95

=0.9 × 95

=$85.5

Sales tax of 10%

10% of the new price

=10/100 × 85.5

=0.1 × 85.5

=$8.55

Sales tax =$8.55

Total amount paid for the jeans= sales tax + new tax

=$8.55 + $85.5

=$94.05

Step-by-step explanation:

Answer:

The mean size of the shoe is 7.

Step-by-step explanation:

We are given the shoe size for all the pairs of shoes in a person closet below;

X = 7, 7, 7, 7, 7, 7, 7, 7, 7, 7.

And we have to find the mean of the data.

Let X = shoe size for all the pairs of shoes

As we know that the mean of any discrete data is given by the following formula;

               Mean, [tex]\bar X[/tex] = [tex]\frac{\text{Sum of all the observations}}{\text{Total number of observations}}[/tex]

Here, the number of observations = 10

                              =  [tex]\frac{7+7+7+7+7+7+7+7+7+7}{10}[/tex]

                              =  [tex]\frac{70}{10}[/tex]  = 7

Hence, the mean size of the shoe is 7.

Answer:

The probability is 23/30, .77, or 77 percent.

Step-by-step explanation:

Add up all the non cherry options, then put them over the total, 30. You would get 23/30, or .7666666666..., which is also known as about 77 percent. So the probability is 23/30, .77, or 77 percent.

the inverse operation of subtraction is addition so you would add 2 on both sides. now you have -4 + 2= -2. now the opposite of multiplication is division. so -2 divided by 2 is -1. hope this helps. Brainliest please!

Answer:

−1=t

Step-by-step explanation:

−4=2t−2

Simplify

First, add the same terms to both of the sides of this equation.

−4=2t−2

−4 + 2 =2t - 2 + 2

Secondly, simplify.

add the numbers

−4 + 2 =2t - 2 + 2

-2 = 2t - 2 + 2

Then,

-2 = 2t - 2+2

-2 = 2t

v

It's simplified to -2 = 2t

Thirdly, Divide both sides of the equation by the same term.

−2=2t

2  over −2

​ =  

2  over 2t

Simplify

(divide the numbers)

2  over −2

​ =  

2  over 2t

which also equals to

(simplify fraction)

−1 =   2  over 2t

-1 = t

Answer:

19 inches

Step-by-step explanation:

Area of a square = s^2

s^2 = 361

s = 19

First multiply the numbers inside the radicals together.

So √3 · √15 is √45.

So we have 2√45.

Note that the 2 can't be multiplied by anything since

√15 has nothing outside of the radical.

So we have 2√45.

Now, break down your square root.

√45 breaks down as 9 · 5 and 9 breaks down as 3 · 3.

Since we have a pair of 3's, a 3 comes outside of the radical

multiplying by the 2 that was previously outside to get 6.

The 5 doesn't pair up so it stays inside.

So our final answer is 6√5.

Answer:

C) [tex]6\sqrt{5}[/tex]

Arithmetic without explanation:

[tex]2\sqrt{3}* \sqrt{15}\\ = 2\sqrt{3}* \sqrt{3*5} \\ = 2\sqrt{3^2} *\sqrt{5} \\ = 2 * 3\sqrt{5} \\= 6\sqrt{5}[/tex]

Example of radical multiplication:

Take [tex]y\sqrt{x} * a\sqrt{b}[/tex]  as an example:

1. Multiple the numbers inside the roots

      [tex]\sqrt{x} * \sqrt{b} = \sqrt{x*b} = \sqrt{xb}[/tex]  

2. Multiple the numbers outside the roots

       [tex]y*a = ya[/tex]

3. Combine them and simplify

      [tex]ya\sqrt{xb}[/tex]

Step-by-step explanation:

We are given the expression [tex]2\sqrt{3}*\sqrt{15}[/tex]

 1. Identify the roots and multiply them

         The roots are [tex]\sqrt{3}[/tex]  and [tex]\sqrt{15}[/tex]

           [tex]\sqrt{3} *\sqrt{15} \\= \sqrt{45}[/tex]

  2. Multiply the numbers outside the root

         For [tex]2\sqrt{3}[/tex] it is [tex]2[/tex] and for [tex]\sqrt{15}[/tex] it is [tex]1[/tex]

          [tex]2*1 = 2[/tex]

  3. Combine and simplify

    Combine:

              [tex]2* \sqrt{45}\\= 2\sqrt{45}[/tex]

   Simplify:

           *Note: [tex]\sqrt{n^2} = n[/tex]

        1. Find the Prime factorization of 45

                   [tex]45 = 3^2 * 5[/tex]

        2. Simplify the Root

                  [tex]2\sqrt{45} \\ = 2\sqrt{3^2 * 5} \\= 2\sqrt{3^2} * \sqrt{5} \\= 2 * 3\sqrt{5}\\ =6\sqrt{5}[/tex]

We end up with [tex]6\sqrt{5}[/tex]
