Answer:

192 cm

Step-by-step explanation:

length of the ribbon needed = perimeter of right angled triangle x 2

to determine perimeter, the value of the hypotenuse needs to be known

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

32² + 24²

= 1024 + 576

= 1600

square root = 40

length of rope = 2 x (40 + 32 + 24) = 192

The Ramos family wants to buy a Play Station 4 for $299.00, along with accessories and games. A wireless controller costs $44.99

Lilit [14]

Answer:

Part A: 299 + 45A + 30B + 50c

Part B: 569 (or 570 if you round it up)

Step-by-step explanation:

Part A:

Because there is no variable for the number of PlayStation 4s, let's assume that there is only one. That will be 299.

If A is the number of wireless controllers and each wireless controller is worth 45 dollars each, the price for the wireless controller(s) is 45A.

If B is the number of wireless controller charging stations and each wireless controller charging station cost 30 dollars, then the price of the wireless controller charging station(s) is 30B

If C is the number of games and each game cost 50 dollars, then the price of the game(s) is 50C

Put that all together, and we get 299 + 45A + 30B + 50c.

Part B:

Let's plug the numbers into the formula.

A = 2

B = 1

C = 3

$299 + 45A + 30B + 50c = 299 + 90 + 30 + 150 = 569\ dollars$

Which of the following expressions represent 15% tip on a $20 meal? Which represents the total bill? **Select all that apply**.

kifflom [539]

Answer:

15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.
