Answer:

50, 40, 30, 250, 350

Step-by-step explanation:

1/2 = 0.5, 0.5 x 100 = 50 (0.5 -> 5 -> 50)

2/5 = 0.4 (10 / 5 [the denominator] = 2, 0.2 x 2 [the numerator] = 0.4), 0.4 x 100 = 40 (0.4 -> 4 -> 40)

3/10 = (10 / 10 [the denominator] = 1, 0.1 x 3 [the numerator] = 0.3), 0.3 x 100 = 30 (0.3 -> 3 -> 30)

5/2 = 2.5 (2 1/2), 2.5 x 100 = 250 (2.5 -> 25 -> 250)

7/2 = 3.5 (3 1/2), 3.5 x 100 = 350 (3.5 -> 35 -> 350)

Note: I'm not sure if I understand the question completely, but I changed the fraction into a decimal and multiplied it by 100. Not sure what it means by "Divide fraction".

Answer:

According to the question , firstly we have to divide the fraction and then convert them into percentage

So , let's do it :-

1/2 = 0.5 = 50 %2/5 = 0.4 = 40 %3/10 = 0.3 = 30%5/2 = 2.5 = 250%7/2 = 3.5 = 350%

Answer: pi is 3.14

and it would be 3.1

Step-by-step explanation:

Answer:

1:28.26

2:28.30

Step-by-step explanation:

since Pi ([tex]\pi[/tex]) is 3.14 and the radius is 9 in we multiply:

  [tex]\pi[/tex]

x 9

28.26 and then we have too round for question 2 so we use the "5 or more go up 4 or less go down" rule and since theres a decimal were rounding the 0.26, so we take away the 0.2, now we have 0.06, and since 6 is 5 or more we round up turning it to 0.1, Now we bring back the 0.2 and add them to make 0.3 or 0.30, lets not forget about the 28 and 28 + 0.30 = 28.30 or 28.3 since there is no need for a zero to be there.

Marissa compared coffeepot prices at three different stores. One of the stores advertised a discount, one was an online store that charged shipping, and one just showed a regular price. The prices are shown below:

Name Price Discount
American Discounters $149.49 30%
The Coffee Hut $91.99 15% of the cost of the item
The Bean $106.49

Part A:
What is the least expensive place to purchase the coffeepot? (Round your answers to the nearest cent.)

Part B:
Sales tax for all 3 retailers is 7.5%. What is the cost to purchase the cheapest coffeepot?

Answers

Answer:

Part A: The Coffee Hut | Part B: 104.25

Step-by-step explanation:

Part A: the coffee hut is the cheapest rounded or not rounded

Part B: 91.99 ÷ 7.5 = 12.26 + 91.99 = 104.25

Answer: Part A is the  American Discounters at $104.64 Part B is $112.49

Step-by-step explanation:

Am. Disc.  =  149.49 minus 30% = 149.49 -44.85 = 104.64.  

Coffee Hut = 91.99 plus shipping (15% ) or  $13.80 = $105.79.

The Bean = $106.49

Am. Discounters is cheapest.

Add in the tax = 7.5% of 104.64 = 7.85 for a total of  112.49

A standard number cube, numbered 1 through 6 on each side, is rolled 3 times. What is the probability of rolling a 2 on all three rolls? Enter the answer as a fraction

Answers

Rolling a 2 on a standard dice is 1/6. So multiply 1/6 *1/6 * 1/6= 1/36

Answer:

1/(6^3)

Step-by-step explanation:

Each roll of the die constitutes a separate event.

These three events are independent.

The probability of rolling a 2 on the first throw is 1/6, since there is only one '2' among the six numbers on the die.

Because each roll is independent of the others, the probability of rolling a

2                                                              1

on all three rolls is (1/6)(1/6)(1/6), or -----------

Answers

Answer:

9.85 - 1.15 = 8.70

Step-by-step explanation:

you jus subtract :)  

Answer:

  $1.90

Step-by-step explanation:

Let n represent the cost of a notebook. Jenna's purchase is ...

  4n +3(n -1.15) = 9.85

  7n - 3.45 = 9.85 . . . . . simplify

  7n = 13.30 . . . . . . . . . . add 3.45

  n = 1.90 . . . . . . . . . . . . divide by 7

The cost of a notebook is $1.90.

_____

Additional comment

The cost of a folder is 1.90 -1.15 = 0.75. The total purchase is ...

  4(1.90) +3(0.75) = 7.60 +2.25 = 9.85

one family spends $134 on 2 adult tickets and 3 youth tickets at an amusement park. Another family spends $146 on 3 adult tickets and 2 youth tickets at the same park. What is the price of a youth ticket?

Answers

Step-by-step explanation:

let

adult ticket = x

youth ticket = y

1). 2x+3y = 134

2). 3x+2y = 146

*then multiply line 1). by the first number of line 2).

*then multiply line 2). by the first number of line 1).

1). (2x+3y = 134 ) x 3 = (6x + 9y = 402)

2). (3x+2y = 146) x 2 = (6x + 4y = 292)

*subtract new line 2). from new line 1).

5y = 110

y = 110/5 = $22

This is the value for youth ticket.

If another question asks for adult you do as follows:

*put this value for y in either original equation, I'll chose line 1).

2x+3y = 134

2x + (3x22) = 134

2x + 66 = 134

2x = 68

X = 68/2 = $34.
