Answer:he eighth sweater costs $29

Step-by-step explanation:

Let the price of the eighth sweater be re[presented as X

We know that

Mean Price =Total sum of cost of sweater bought/ Number of sweater'

Plugging in our known values we have that  

40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X  /8

8 X 40 =291 +X

320=291 +X

X =320-291

X=29

Therefore, the eighth sweater costs $29

Answer: 29

Answer:

( x + 2 )² + ( y - 1 )² = 25

Step-by-step explanation:

Circle equation - ( x - h )² + ( y - k )² = r²

Important notes:

(h,k) = center

r = radius

The first step would be to find the center

( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )

Like stated before ( h , k )  = center point

* replace center point with (-2,1) *

( h , k ) = ( -2 , 1 )

h = -2

k = 1

* plug in the h and k values into the circle equation *

now we have ( x - ( -2) )² + ( y - 1 )²

Now to find the radius

We can find the radius by using the distance formula with the center point and any point on the circle's outline

The point chosen can vary but i chose (3,1)

Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius

3 - (-2)

the two negative signs cancel out

3 + 2 = 5

So the radius equals 5

* plug in the value of the radius into the equation *

Now we have

( x - (-2) )² + ( y - 1 )² = 5²

our final step is to simplify

- (-2) the two negative signs cancel out and it turns into +2

5² = 25

Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

Answer:

[tex]63\ \text{ft}[/tex]

Step-by-step explanation:

The distances are shown in the figure

[tex]\tan25^{\circ}=\dfrac{p}{b}\\\Rightarrow p=b\tan25^{\circ}[/tex]

[tex]\tan15^{\circ}=\dfrac{p}{b+100}\\\Rightarrow p=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b\tan25^{\circ}=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b=\dfrac{100\tan15^{\circ}}{\tan25^{\circ}-\tan15^{\circ}}\\\Rightarrow b=135.08\ \text{ft}[/tex]

[tex]p=b\tan25^{\circ}=135.08\times\tan25^{\circ}\\\Rightarrow p=62.99\approx 63\ \text{ft}[/tex]

The width of the river is [tex]63\ \text{ft}[/tex].

Answer:469.08

Step-by-step explanation:

The number is written as 469800

Numbers can be expressed both in words and figures. For example, 100,000 in words is written as One Lakh or One hundred thousand. Numbers in words can be written for all the natural numbers, based on the place value of digits, such as ones, tens, hundreds, thousands, and so on.

Given here, the number in words here is Four hundred sixty-nine and eight hundredth. Thus the number in figures is  469800

Hence, the number in figures is 469800

The LCM of 210 and 450 is: 3150

Answer:

1. Find the prime factorization of 210

210 = 2 × 3 × 5 × 7

2. Find the prime factorization of 450

450 = 2 × 3 × 3 × 5 × 5

3. Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 3 × 3 × 5 × 5 × 7

2nd story: 3x+5 = 17

3rd story: 5x+3 = 17

Answer:

x = 2.66666667

Step-by-step explanation:

3(x + 1) = 11

We multiply both x and 1 by 3 and get

3x + 3 = 11

Now we subtract 3 from both sides

3x + 3 - 3 = 11 - 3

3x = 8

Now divide both sides by 3

3x/3 = 8/3

x = 2.66666667
