Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom bought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups.

Answers

Answer:

Cups = 24

Plates = 48

Balloons = 12

Total = 84

Step-by-step explanation:

Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom brought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups. If Serena's mom bought 84 items, how many of each item did she buy.

Let

c = number of cups

Serena's mom bought twice as many plates as cups.

2c = number of plates

number of balloons Serena's mom bought was half the number of cups

0.5c = the number of balloons

Total items = 84

c + 2c + 0.5c = 84

3.5c = 84

Divide both sides by 3.5

3.5c / 3.5 = 84 / 3.5

c = 24

c = number of cups = 24

2c = number of plates = 2 * 24 = 48

0.5c = the number of balloons = 0.5*24 = 12

Cups = 24

Plates = 48

Balloons = 12

Total = 84

Answers

Answer:

44/15 converted into a mixed number   = 2(14/15)

Step-by-step explanation:

44/15 =     2.9333333...... = 2( 14/15)

so it is the number 2 and   (0.93333)

Lets see how is  the  decimal is in fraction

0.93333  is a mixed recurrent number  and in fraction is  14/15

14/15 = 0.93333.....

With recurring  mixed  decimal :

Take the non-repeating and the repeating(93) and subtract the non repeating(9)

93-9= 84

For the bottom part: for  every repeating decimal,you put a 9  And for every non repeating decimal,you put a zero

so one 9 and one zero (90)

84/90  = 14/15  = 0.93333....

Tyler has a stack of cards. He picks a card, records the color, and returns the card to the stack. He repeats this 60 times and chooses a red card 24 times. What is the experimental probability of choosing a red card from the stack?

Answers

Answer:

24/60 = 2/5

Step-by-step explanation: dont have one

Answer:

2/5, or 40%

Step-by-step explanation:

The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.

A 7/10

Step-by-step explanation:

if you make it even, you double the 4/5 to make it a 8/10, if you every have a number that is like 4/6-2/18, you triple the 4 to make 12, and triple the 6 to make it 18. so you now have 12/18-2/18=10

Akiko ate 60 hot dogs in 10 hours. At that rate, how many hot dogs would she eat in 20 minutes?

Answers

Akiko ate per hour:-

Total hot dogs/Total hours60/106dogs/hour

So

20min=1/3h

Total hot dogs

6/32

Answer:

2 hot dogs

Step-by-step explanation:

Total hot dogs she ate in 10 hours,

→ 60 hot dogs

Total hot dogs she ate in 1 hour,

→ 60/10

→ 6 hot dogs

The fraction of 20 minutes in a hour,

→ 20 minutes/1 hour

→ 20/60

→ 2/6 = [ 1/3 ]

Rate of hot dogs she ate in 20 minutes,

→ 6 × 1/3

→ 6/3

→ [ 2 hot dogs ]

So, Akiko ate 2 hot dogs in 20 minutes.
