Step-by-step explanation:

The initial number of party favor bags Razee had to fill were 48 bags.

Here, we will use arithmetic progression to solve this problem.

We are given that:

At 4 minutes, 36 bags were remaining.

At 5 minutes, 32 bags were remaining.

At 6 minutes, 28 bags were remaining.

At 7 minutes, 24 bags were remaining.

This can also be written as:

a₄ = a + 3d = 36

a₅ = a + 4d = 32

a₆ = a + 5d = 28

a₇ = a + 6d =24

where a is the initial number of party favor bags.

a₅ - a₄ = a + 4d - a - 3d

a + 4d - a - 3d = 32 - 36

d = -4

a + 3d = 36

a + 3(-4) = 36

a - 12 = 36

a = 36 + 12

a = 48

Therefore, the initial number of party favor bags Razee had to fill were 48 bags.

Step-by-step Turn 7 into a fraction

3/5 ÷ 7/1

Use the recipricle and multiply

3/5 x 1/7

Multiply across

3/35

And that's it! :)

Answer:

5/21

Step-by-step explanation:

Here is a strategy I want you to remember: Keep, Change, Flip. What do I mean by that? Well...

Keep the first fraction. Change the division sign into a multiplication sign. Make the numerator of the second fraction become the denominator--and make the denominator of the second fraction become the numerator.

The denominator of any whole number is always 1. So, 7 equals to 7/1. Time to find the reciprocal of 7/1! What does reciprocal mean?

Reciprocal - Flip the fraction in terms of the numerator and denominator; Multiplicative Inverse

1/7 is the reciprocal of 7/1, for this mathematical problem. Makes sense, right?

Now, 5 times 1 equals 5 (that is the numerator). Secondly, 3 times 7 equals 21 (that is the denominator).

Step-by-step explanation:

According to the graph, we see that we have 2 parallel lines. Therefore, there will be no solution.

The time taken by the plain if it flies at a speed of 800 km/h is 6 hours 45 minutes

Given,

Time taken by plain to fly from Los Angeles to New York = 6 hours

Speed of plain = 900 km/h

We have to determine the time taken by the plain if it flies at a speed of 800 km/h

Distance cover by plain = speed x time = 900 x 6

Distance cover by plain = 5400 kilometer

New time taken by plain = Distance cover by plain / New speed of plain

New time taken by plain = 5400 / 800

New time taken by plain = 6 hours 45 minutes

That is, the time taken by the plain if it flies at a speed of 800 km/h is 6 hours 45 minutes

Answer:

a = 20 and b = 21

Step-by-step explanation:

Given:

2a-3b = -23

a and b are consecutive

Find:

a and b

Computation:

a = b - 1

So,

2a-3b = -23

2(b-1)-3b = -23

2b - 2 - 3b = -23

-b = -21

b = 21

So

a = b - 1

a = 21-1

a = 20

Step-by-step explanation: The x-intercepts are at -5 and 7. when you don’t have a negative symbol before the parentheses, that indicates that the parabola will be shaped like a U. when you do, it’s shaped the opposite of a U. and now look at the equation answer.

Answer:

a = 22

switch the sides (a + 2) = 24

a + 2 = 24

subtract 2 from both sides

Answer:

The price of each CD before tax is $15.70

Step-by-step explanation:

Given that:

Number of CDs bought by Reuben = 5

Cost of five CDs = $81.50

Sales tax on each CD = $0.60

Sales tax on 5 CDs = 0.60*5 = $3.00

Price of CDs without tax = 81.50 - 3.00 = $78.50

Price of each CD = [tex]\frac{Cost\ of\ CDs}{No.\ of\ CDs}[/tex]

Price of each CD = [tex]\frac{78.50}{5}[/tex]

Price of each CD = $15.70

Hence,

The price of each CD before sales tax is $15.70

i) The probability that the number on the ticket is even is [tex]\mathbf{\frac{1}{2}}[/tex]

ii) the probability that the number on the ticket is a number less than 16 is [tex]\mathbf{\frac{6}{23}}[/tex]

iii) The probability that the number on the ticket is a perfect square is [tex]\mathbf{\frac{5}{46} }[/tex]

iv) the probability that the number on the ticket is a prime number less than 30 is [tex]\mathbf{\frac{4}{23} }[/tex]

Step-by-step explanation:

Tickets numbers are: 4, 5, 6......48, 49

So, total tickets in box = 46

We need to find probability that the number on the ticket is:

i) an even number.

Even number in tickets are: 4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48

Total number of favourable outcomes = 23

So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]

Total number of outcomes = 46

Number of favourable outcomes = 23

Putting values and finding probability

[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{23}{46}\\Probability=\frac{1}{2}[/tex]

So, the probability that the number on the ticket is an even number is [tex]\mathbf{\frac{1}{2}}[/tex]

ii) A number less than 16

Even number in tickets are: 4,5,6,7,8,9,10,11,12,13,14,15

Total number of favourable outcomes = 12

So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]

Total number of outcomes = 46

Number of favourable outcomes = 12

Putting values and finding probability

[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{12}{46}\\Probability=\frac{6}{23}[/tex]

So, the probability that the number on the ticket is a number less than 16 is [tex]\mathbf{\frac{6}{23}}[/tex]

iii) a perfect square

Perfect squares are: 4,9,16,25,36

Total number of favourable outcomes = 5

So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]

Total number of outcomes = 46

Number of favourable outcomes = 5

Putting values and finding probability

[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{5}{46}[/tex]

So, the probability that the number on the ticket is a perfect square is [tex]\mathbf{\frac{5}{46} }[/tex]

iv)  a prime number less than 30.

Prime numbers less than 30 are: 5,7,11,13,17,19,23,29

Total number of favourable outcomes = 8

So, the formula used is: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}[/tex]

Total number of outcomes = 46

Number of favourable outcomes = 8

Putting values and finding probability

[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Total\:number\:of\:outcomes}\\Probability=\frac{8}{46}\\Probability=\frac{4}{23}[/tex]

So, the probability that the number on the ticket is a prime number less than 30 is [tex]\mathbf{\frac{4}{23} }[/tex]

Question isn't complete so we assume you wish to solve the equation above

`x-0.1x+2.70=56.70

Answer:

Step-by-step explanation:

To solve this equation

x-0.1x+2.70=56.70

We first find like terms and then subtract both sides of the equation

x-0.1x+2.70=56.70= 1x-0.1x+2.70=56.70

Add like terms

0.9x+2.70=56.70

Subtract both sides of equation

0.9x=56.70-2.70

Divide both sides

0.9x=54

x=54/0.9

x= 60
