The clothes weigh 14.77 kilograms.

Given:
Weight of suitcase = 50 pounds
Towels = 20% of weight
Shoes = 15% of weight
Clothes = 65% of weight

convert pounds to kilograms using proportion:

<u>pounds</u>        <u>2.2</u> = <u>50</u>
kilograms       1           x

2.2x = 50 ⇒ x = 50/2.2 ⇒ x = 22.73 kgs

Clothes : 22.73 kgs * 65% = 14.77 kgs
Towels  : 22.73 kgs * 20% =   4.55 kgs
Shoes   : 22.73 kgs * 15% =   3.41 kgs

∠A +∠B+∠C+∠D=360°

14x-11+8x+7+5x+18+10x+13=360°

37x+27=360°

37x=333

x=9

so,

m∠B=8x+9

m∠B=8×9+7

m∠B=79°

Tickets to a show cost $5.50 for adults and $4.25 for students. A family is purchasing 2 adult tickets and 3 student tickets.
jarptica [38.1K]

The exact cost is $23.75 for the show, and the exact change they should get is $1.25.

An adult ticket to the show costs $5.50

A student ticket to the show costs $4.25.

A family buys two adult tickets and three student tickets. This would imply that the total cost of two adult tickets would be

⇒ 2 × 5.5 = $11

It also implies that the total cost of three student tickets is

3 × 4.25 = $12.75

The total cost of two adult tickets and three student tickets is

⇒ 11 + 12.75 = $23.75

If the family pays $25, the exact change they should get is

⇒ 25 - 23.75 = $1.25

Thus, the exact cost is $23.75 for the show, and the exact change they should get is $1.25.
