number of different 5 digit combinations if successive digits msut be different

Answers

Answer 1
for the first digit you have 10 options (0..9).
For each next digit you can't choose the same digit, so you have 9 options.

So number of combinations is 10*9*9*9*9 = 65610
Answer 2

The permutations formula is applied to determine the number of different 5-digit combinations where successive digits must be different, resulting in a total of 30,240 combinations.

Permutations are used when the order of elements matters. In this case, the number of different 5-digit combinations where successive digits must be different can be calculated using the permutations formula.

Identify that we need to use permutations due to the order of elements being important.Calculate the number of possibilities for each digit decreasing by 1 with each selection. For a 5-digit number, it would be 10 choices for the first digit, 9 for the second, 8 for the third, 7 for the fourth, and 6 for the fifth.Calculate the total number of combinations by multiplying the number of choices for each digit together: 10 x 9 x 8 x 7 x 6 = 30,240.

What's the answer to this question ? I've been really confused for the past 20 minutes

Answers

the hint tells you s is sqrt(a)

 the question tells you a = 570025

so side = sqrt(570025)

 plug that into your calculator to get:

755 feet

21) Each side is 755 in
To do this all you'll need to do is find the root of 570,025, which is 755

22) Each side is 25 in
Again, you'll need to find the square root of 625, which is 25

a digital scale measures weight to the nearest 0.2 pound. which measurement shows an appropriate level of precison for the scale?

A. 130.4 pounds

B. 125 pounds

C.120 pounds

D. 124.75 pounds


Answers

I think it would be A. 130.4 if it is measuring to the nearest 0.2 pound

Answer:

130.4 pounds

Step-by-step explanation:

The digital scale is measuring weight to the nearest 0.2 pounds, so basically the digital scale would show you the weight of an object that is a multiple of 0.2.

Talking about precision, precision tells us how accurate is the measured value or how close is the measured value to the actual value.

Here, scale is measuring to the nearest 0.2 pounds, so out of the given values the measurement that shows an appropriate level of precision for the scale is 130.4 pounds.

divide , round to the nearest tenth
336.752 divided by 31

Answers

it    is   originally 10.829677419 so rounding to the nearest tenth would be 10.9

Answer:

Round to the nearest tenth  336.752 divided by 31 is 10.9

Step-by-step explanation:

Consider the provided information.

336.752 divided by 31

This can be written as:

336.752 ÷ 31

Divide the number as shown:

[tex]\frac{336.752}{31}[/tex]

[tex]10.862968[/tex]

Now we need to round it to the nearest tenth.

According to the place value:

Tens   Ones   Decimal point   Tenths   Hundredths

 10         1                    .                0.1           0.01

According to place value tenths place is just after the decimal point so round the number to just after decimal point.

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, round it up by one number.

Here, the number at the hundredths place is 6 so round it up.

Thus, the  round to the nearest tenth is 10.9

A real world problem for the equation 0.75x - 18.50 = 0.65x

Answers

Diana had chocolate, and ate some, leaving 0.75 of it for Sarah. 

Sarah ate 18.5 grams of it and return the rest to Diana, which was 65% of the original chococate. 

how much chocolate did Diana have at the beginning?

and the solution is: 

0.75x-18.50=0.65x 

0.75x-0.65x=18.50
0.1x=18.50
x=185

so Diana had 185 grams of chocolate.

Suzi starts her hike at -225 feet below sea level. When she reaches the end of the hike, she is still below sea level at -127 feet. What was the change on elevation from the beggining of Suzi's hike to the end of the hike?

Answers

Positive 98 is the difference. From -225 to 127 is getting closer to positive numbers.

The change in elevation from the beginning of Suzi's hike to the end is 98 feet, as calculated by the difference in starting and ending elevations: (-127) - (-225) = 98 feet.

To calculate the elevation change, we subtract the elevation at the start of the hike from the elevation at the end of the hike. Suzi started at -225 feet below sea level and ended at -127 feet below sea level.

To find the change in elevation, we perform the following calculation:

Write down the starting elevation: -225 feet.

Write down the ending elevation: -127 feet.

Subtract the starting elevation from the ending elevation: (-127) - (-225).

Simplify the equation by adding: -127 + 225 = 98 feet.

Therefore, the change in elevation from the beginning of Suzi's hike to the end is 98 feet. The positive result indicates an increase in elevation, even though Suzi is still below sea level at the end of her hike.

How many meter of cloth is needed if Aling Luding to make 25 pillowcase if each pillowcase needs 95 cm long cloth?

Answers

23.75
this is because there would be 2375cm if you didn't convert it into meters
 

Aling Luding will need 23.75 meters of cloth to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth. We convert the total centimeters to meters by dividing by 100.

To calculate the total amount of cloth Aling Luding needs to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth, we need to perform a simple multiplication. We multiply the number of pillowcases by the length of cloth needed per pillowcase.

Therefore, the calculation will be:

25 pillowcases  imes 95 cm per pillowcase = 2375 cm.

However, we often measure fabric in meters, so we need to convert centimeters to meters. There are 100 cm in a meter, so:

2375 cm \/ 100 = 23.75 meters.

So, Aling Luding needs 23.75 meters of cloth in total to make 25 pillowcases.

55 miles per hour write a algebric expression to show how far the car will travel in a certain number of hours

Answers

55miles in an hour  times x( # of hours that are unknown)
Final answer:

The algebraic expression for the scenario is 'd = 55t', where 55 (miles per hour) is the constant, and 't', which represents time in hours, is the variable. This expression is used to calculate the distance traveled by a car.

Explanation:

The subject of your question is algebra, particularly involving the concept of linear equations. In this scenario, you're looking to determine how far a car will travel given a certain speed and number of hours. Your constant in this case will be the speed of the car, which is 55 miles per hour. The variable is the time in hours, which we can denote by 't'. Hence, the algebraic expression representing this scenario would be d = 55t where 'd' represents the distance traveled by the car. The distance is calculated by multiplying the constant speed by the variable time.
