flynn opens a saving account. In one 3 month period, he makes deposit of $75.50 and $55.25. He makes withdrawal of $25.15 and $18.65. His balance at the end of the 3 month period is $210.85. Explain how you can find his initial deposit amount?

Answers

Answer 1

Answer: By adding all of the amounts up: 75.00+55.25= 130.25, afterwords you need to add up the amount that Flynn spent, which is 25.15+18.65= 43.80, Once you have these two numbers. You need to subtract them from each other which looks like this: 130.25-43.80=86.45, then by subtracting that number from the last amount: 210.85-86.45=124.4.
The initial deposit is: 124.4
And to check your answer, you have to add 130.25+124.4=254.65, and then: 254.65-43.80= 210.85.

Answer 2

Answer: x=initial deposit amount.
we have to add to the initial deposit amount the incomes and subtract the withdrawal
x+($75.5+$55.25)-($25.15+$18.65)=$210.85
Now we solve this equation.
x+$130.75-$43.8=$210.85
x+$86.95=$210.85
x=$210.85-$86.95
x=$123.9

Answer: his initial deposit amount is $123.9

If one woman is selected find the probability that her height is less than 65 inch with a mean of 64.4 and standard deviations of 1.8

Answers

The probability of one woman to have height less than 64.4 in is 0.6293

Explanation:

Given:

Mean, μ = 64.4

Standard deviation, δ = 1.8

Probability that the height of the woman is less than 65 inch = ?

So,

P(x < 65) = 65 - μ / δ

$=(65 - 64.4)/(1.8)\n \n= 0.33$

P (x < 65) = P( z < 0.33)

Finding the probability value from the z table we get:

P( z < 0.33) = 0.6293

Therefore, the probability of one woman to have height less than 64.4 in is 0.6293

the room charge for a hotel is 230$ each day. the estevez family spends 4 days on vacation at the hotel . at the end of their stay they leave a 10% tip of the total room bill for the person who cleans their room. how much is the total bill including the tip for the person who cleans the room? explain

Answers

It's 230 per day and they spend 4 days so multiply 230 × 4 = 920

920 is the room charge. Now multiply 920 × 10% for the tip.

920× .10 = 92 that's the top

Add the tip to the room charge

920 + 92 = $1,012

10% of 230 is 23 so
230
+23 =
253
hope i helped:)

How do you compare whole numbers through the millions

Answers

Whole numbers are the numbers 0, 1, 2, 3, 4, 5, 6...and so on. It is easier to compare two numbers through the millions using a place value chart. This is illustrated in the Figure bellow. In that example, we have chosen two numbers:

Number one:8,472,102

Number two:8,470,443

So, by comparing these numbers we will have the following steps:

Step 1. The millions are both 8.

Step 2. The hundred thousands are both 4.

Step 3. The ten thousands are both 7.

Step 4. The one thousands digits are 2 and 0.

Stop in this step and compare the digits, so:

2 is greater than 0 or 2 > 0

Therefore, the solution is:

Number one > Number two, that is:

8,472,102 > 8,470,443

In conclusion, you need to stop in the step at which the digits are not the same and compare them. The greatest number is the one with the greatest digit.

A positive number is greater than a negative number. If both numbers are positive, the longer number - the one with more digits - is larger.
