A square playground is surrounded by a sidewalk on all sides. The sidewalk is 2n+3 yards along each side. The sidewalk is 0.5 ya
soldi70 [24.7K]

Answer: It  can be calculated by using the formula of perimeter and by adding four sides

1) Perimeter= 2(L+B)= 8n+12

2) Perimeter= L+L+L+L= 4L= 8n+12

Step-by-step explanation:

As it is a square playground all its sides are equal

Perimeter of the sidewalk = 2(L+B)= 2(2n+3+0.5)= 2(2n+3.5)= 4n+7

Perimeter of the square playground= <em><u>2(L+B)</u></em>= 2(2n+3+2n+3)

<em>2(4n+6)= 8n+12-------------------------A</em>

Perimeter of the square playground<u><em>= L+L+L+L=4L</em></u>  42n+3+2n+3+2n+3+2n+3=<u><em>4(2n+3)= 8n+12------------------------B</em></u>

Help me some one plz (only part b)
Slav-nsk [51]

The school can expect to raise 1500p for charity.

<u>Explanation:</u>

(a)

The possibility space is solved in the image attached.

(b)

20p for each player

30p for lollipop

Number of people = 120

Charity amount = ?

Out of 12 outcomes, the probability of getting 7 is 3

So, probability of getting 7 for 120 people = \frac{3}{12} X 120

                                                                  = 30

Money earned from the players = 20p X 120

                                                  = 2400p

Cost of 30 lollipops = 30p X 30

                               = 900p

Money received for charity = 2400p - 900p

                                          = 1500p

                                         

Therefore, the school can expect to raise 1500p for charity.

Question 1
kenny6666 [7]

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let y represent the number of soccer balls and x represent the number of volleyballs.

The coach can spend a maximum of $1,100, hence:

20x + 25y ≤ 1100

Also, The coach plans to order at least 50, hence:

x + y > 50

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50
