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

Answer:

n=-3 or n=8

Step-by-step explanation:

Let's solve your equation step-by-step.

n2−5n=24

Step 1: Subtract 24 from both sides.

n2−5n−24=24−24

n2−5n−24=0

Step 2: Factor left side of equation.

(n+3)(n−8)=0

Step 3: Set factors equal to 0.

n+3=0 or n−8=0

n=−3 or n=8

Answer:

n=−3 or n=8

Answer:

46.05degrees

Step-by-step explanation:

Given the following

Height of tree = 18ft (Opposite)

length of shadow = 25ft (hypotenuse)

Required

Angle of elevation

Sin theta = opp/hyp

Sin x = 18/25

sin x = 0.72

x = arcsin(0.72)

x = 46.05

Hence the angle of elevation of the sun is 46.05degrees

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

Answer:

D

Step-by-step explanation:

When tossing a coin, there are two possibilities, heads or tails, thus one can rule out the first option. When rolling a pyramid-die, then there are four different possibilities, each one with an equally likely chance, and each one's outcome is non-dependant on the outcome of the coin toss. Thus options (B) and (C) can be ruled out. Therefore, option (D) is the only remaining valid option.

Step-by-step explanation:

Sorry i dont know how to do the pi symbol

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

The answer of this question is 13°

Step-by-step explanation:

(9x-17)+(4x+28)=180° ( Being cointerior angle of parallel line)

or, 9x-17+4x+28=180°

or, 13x+11=180°

or, 13x=180°-11

or, x= 169°÷13

Answer:

Step-by-step explanation:

Answer:

Part A     A.  400 sq ft.

Part B     A.   509 sq ft

Step-by-step explanation:

Part A

Area of square = side squared

Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20

A = 20^2 = 400 sq ft

Part B

C = πd

80 =

80/π = d

r = d/2 = 80/2π = 40/π

A = πr^2 = π(40/π)^2

   = 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft

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
