Answer:

Step-by-step explanation:

To find it we will divide the miles from hours

= 110 ÷ 2 = 55

165 ÷ 3 = 55

220 ÷ 4 = 55

The answer is 55

The simple interest formula is A = P(1 + r)t where P represents the amount originally deposited, r is the interest rate, and A i

To find this, you just need to plug it in and use some algebra to figure it out.
Initial:                                 2700 = 2200(1 + r)5
multiply 2200 and 5:             2700 = 11000(1 + r)
Divide both sides by 11000:     .24 = 1 + r
subtract both sides by 1:        -.754 = r

The problem is, a negative interest rate makes no sense if there was actually an increase of 500. We can try distributing the 11000 instead
Where we left off:                              2700 = 11000(1 + r)
Distribute the 11000:                         2700 = 11000 + 11000r
Subtract 11000 from both sides:        -8300 = 11000r
Divide both sides by 11000:                -.754 = r

As you can see, both methods reached the same impossible answer. I'm assuming that you didn't type out the equation right. Are you sure it wasn't 
2700 = 2200(1 - r)5
? If you subtract the r to make it negative, it might make more sense. But that still leaves us with a .754 rate of interest, which seems too high. Double check where you're typing from

7) Heather records the number of winners of the three Ring Toss game in the table below.
siniylev [52]

The number of winners that Heather can expect is 300.

<h3>How many winners can be expected?</h3>

The first step is to determine the total number of winners to the total number of players using the information in the table.

  • Total number of winners = 52 + 63 + 65 = 180
  • Total number of players = 123 + 155 + 172 = 450

Ratio = 180 / 450 = 0.40

Number of winners if there are 750 players = 0.40 x 750 = 300 winners
