Raffle tickets are sold and 6 prizes are available for the lucky draw. A total of 1,356 raffle tickets are sold for 4/5 dollars each and the 6 prizes cost 8 3/10 each. How much money was raise from the raffle tickets?

Answers

Answer:

US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of raffle tickets sold = 1,356

Cost of each raffle ticket = US$ 4/5

Number of prizes = 6

Cost of each prize = US$ 8 3/10

2. How much money was raised from the raffle tickets?

For easier calculation, let's convert the fraction numbers to decimal numbers:

Cost of each raffle ticket = US$ 4/5 = US$ 0.80

Cost of each prize = US$ 8 3/10 = US$ 8 + 0.30 = US$ 8.30

Now, we use this formula to calculate how much money was raised and the profits:

Profits = (Number of tickets sold * Cost of each ticket) - (Number of prizes * Cost of each prize)

Replacing with the real values, we have:

Profits = 1,356 * 0.80 - 6 * 8.30

Profits = 1,084.80 - 49.80

Profits = 1,035

US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.

Calcule o perímetro do retângulo, considerando raiz de 3= 1,7

The perimeter of the rectangle is 21.6 m

Further explanation

To solve the above questions, we need to recall some of the formulas as follows:

Area of Square = (Length of Side)²

Perimeter of Square = 4 × (Length of Side)

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Rhombus = 4 × ( Length of Side )

Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

Let us now tackle the problem !

Given:

Length of Diagonal = d = 8 m

Angle Between Diagonal and Width = θ = 60°

Unknown:

Perimeter = ?

Solution:

See the picture in the attachment ,

\sin \theta = (BC)/(AC)

\sin 60^o = (BC)/(8)

(1)/(2) √(3) = (BC)/(8)

BC = 8 * (1)/(2) √(3)

BC = 4 √(3)

BC = 4(1.7)

\boxed {BC = 6.8 ~ m}

\cos \theta = (AB)/(AC)

\cos 60^o = (AB)/(8)

(1)/(2) = (AB)/(8)

AB = 8 * (1)/(2)

\boxed {AB = 4 ~ m}

Perimeter ~ = 2 ( AB + BC )

Perimeter ~ = 2 ( 4 + 6.8 )

Perimeter ~ = 2 ( 10.8 )

\large {\boxed {Perimeter ~ = 21.6 ~ m} }

You divide $2.50 by 2, not 2 by $2.50. Therefore, $2.50 by 2 is $1.25 per pound, not $0.80
