Answer:

609638400

Step-by-step explanation:

Each row must alternate boys and girls, so every row is either BGBGB or GBGBG, where B denotes a boy and G denotes a girl. Since there are 8 girls and 7 boys, the teacher must have two rows of GBGBG and one row of BGBGB. There are three ways to choose this row, and once this is done, every seat is reserved for either a girl or a boy. There are 8! ways to arrange the girls in their seats, and 7! ways to arrange the boys, so the total number of seating arrangements is 3 * 7! * 8!

158,400 people will fit into an area with a dimension of 30feets by 2 miles.

The area of the street can be calculated thus :

Area = Length × width

Converting the width to feets :

1 mile = 5280 feets

2 miles = x

Cross multiply :

x = 5280 × 2 = 10560 feets

Area = 10560 ft × 30ft = 316800 ft²

Since 15 people fit into an area with dimension which is 6 ft by 6ft

Area = 6 × 6 = 36 ft²

Let x = number of people

15 people = 36 ft²

x people = 316800 ft²

Cross multiply :

x = (316800 × 15) / 36

x = 158,400 people

Hence 158,400 people will fit in.

Answer:

2

Step-by-step explanation:

18/(2+7)=18/9=2

500 at 40 each = £20000

To make a profit he needs to make more than £20000

20 broke so he sold 500-20 = 480 at 45 each.

480 x 45 = 21600

Profit = 21600 -20000 = 1600

His profit was £1,600

Answer:

x = 13, y = 24.

Step-by-step explanation:

5x - 8 + 63 + 7x - 31 = 180  (interior alternate angles are equal).

12x + 24 = 180

12x = 180 - 24 = 156

x = 156/12

x = 13.

4y + 27 =  63 + 7x - 31       (interior alternate angles are equal).

4y +27 = 32 +7(13)

4y = -27 +32 + 91

4y = `96

y = 96/4

y = 24.

Answer:

P = 2( 8v +3w)

P = 16v +6w

Step-by-step explanation:

P = 2 ( l+w) for a rectangle

P = 2((3v+7w)+ (5v-4w))

Combine like terms

P = 2( 8v +3w)

Distribute

P = 16v +6w

Answer:

-175/31

Step-by-step explanation:

-301 = -3x = 7(4x – 18)

-301 = -3x = 28x - 126

-301 = 31x = -126

-175 = 31x

x = -175/31

Answer:

1.06 m²

Step-by-step explanation:

To find the area of the two ends, you need to find the area of the inner circle, then subtract that from the area of the large circle.

As we know, A = πr²

The diameter of the larger circle is 1.8, so the radius is 0.9.

π(0.9)² = 2.54

The diameter of the smaller circle is 1.6, so the radius is 0.8

π(0.8)² = 2.01

2.54 - 2.01 = 0.53 m² (this is for one end)

0.53 x 2 = 1.06 m²

Answer:

(0, - 6 )

Step-by-step explanation:

The midpoint is the average of the x- coordinates and y- coordinates, that is

midpoint = ( [tex]\frac{-3+3}{2}[/tex] , [tex]\frac{-7-5}{2}[/tex] ) = ( [tex]\frac{0}{2}[/tex], [tex]\frac{-12}{2}[/tex] ) = (0, - 6 )

Step-by-step explanation:

Open the brackets

2t+1-t+9 = -52-8t

Collect the like terms

2t-t+8t = -52-1-9

9t= -62

Divide both sides by 9

t= -62/9

= -6.88

Approximately -6.9

Answer:

x = [tex]\frac{40}{9}[/tex] , x = - [tex]\frac{56}{9}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] | [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | - 1 = 1 ( add 1 to both sides )

[tex]\frac{1}{2}[/tex] | [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | = 2 ( divide both sides by [tex]\frac{1}{2}[/tex] )

| [tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] | = 4

The absolute value always gives a positive result, however, the expression inside can be positive or negative, then

[tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] = 4 ( multiply through by 12 to clear the fractions )

9x + 8 = 48 ( subtract 8 from both sides )

9x = 40 ( divide both sides by 9 )

x = [tex]\frac{40}{9}[/tex]

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

OR

- ([tex]\frac{3}{4}[/tex] x + [tex]\frac{2}{3}[/tex] ) = 4 , distribute left side

- [tex]\frac{3}{4}[/tex] x - [tex]\frac{2}{3}[/tex] = 4 ( multiply through by 12 to clear the fractions )

- 9x - 8 = 48 ( add 8 to both sides )

- 9x = 56 ( divide both sides by - 9 )

x = [tex]\frac{56}{-9}[/tex] = - [tex]\frac{56}{9}[/tex]

Answer:

61.84%

Step-by-step explanation:

Let the cost of the box be x. Since the price of the box and the pen is Rs 80, the pen's price can be represented as 80 - x. The box is sold at a ten percent profit, and an added ten percent is equal to 1.1. Therefore, the price the box sells at is 1.1(x). A 20% loss is the same a keeping 80% or multiplying by 0.8. This means the pen sold at 0.8(80 - x). Now, we are given the box went for Rs 28 more than the pen, so we can create an equation:

1.1x = 0.8(80 - x) + 28

We can simplify and solve:

1.1x = 64 - 0.8x + 28

1.9x = 92

x = 92/1.9

x = 920/19

The cost of the box after the increase would be 1.1(920/19) and the pen would be 0.8(80 - 920/19).

The sum of these two can be written as a percent x of 80.

80x = 0.8(80 - 920/19) + 1.1(920/19)

80x = 64 - 0.8(920/19) + 1.1(920/9)

80x = 64 - 0.3(920/19)

80x = 64 - 276/19

80x = 940/19

x = 940/1520

x = 0.6184

This is 61.84%
