The total number of possible 5-digit codes for the garage door opener, where no two adjacent digits are the same, is 59,049.

This is a combinatorics problem in mathematics. A simple way to solve this problem is to calculate the total number of 5-digit code combinations possible without any constraint, which is 10^5 = 100,000.

However, the condition given in the problem is that no two adjacent digits can be the same. The possible codes for the first digit are 10 (0-9). For the second digit, because it cannot be the same as the first, there are 9 possibilities, the third digit also has 9 possibilities because it cannot be the same as the second, and so on.

Therefore, the total number of possible codes is 10 * 9 * 9 * 9 * 9 = 59,049. Hence, the garage door opener can have 59,049 different codes.

120*0.8 is the expression, because you can put 80% as 80/100 and that is equal to .8 so you just put that in a calculator and thats your answer. Hope that helped :)

Answer:

[tex](0.80)120[/tex]

Step-by-step explanation:

We are asked to find an expression that represents 80% of 120.

We know that % means per hundred. 80% would be 80 divided by 100.

[tex]80\%\text{ of }120=\frac{80}{100}\times 120=(0.80)120[/tex]

Therefore, the expression [tex](0.80)120[/tex] represent 80% of 120.

Answer: [tex]\frac{1}{4^5}[/tex]  because any exponent that is a negative has to be brought down.

Answer:

The answer is 1/45

Step-by-step explanation:

The lowest terms would be 3/16 because you could divide top and bottom by 4

The lowest it vould be is 4:16

This is because the BCF is 4.

[tex]\frac{1}{2.54} =\frac{24}{x}[/tex]

Multiply both sides by 2.54.

[tex]1=\frac{24}{x} (2.54)[/tex]

[tex]= \frac{60.96}{x}[/tex]

Multiply both sides by x.

x = 60.96

Hence, Aaron needs 60.96 centimeters of wire.

Final answer:

Aaron needs 60.96 centimeters of copper wire for his experiment, calculated by multiplying 24 inches by the conversion factor of 2.54 cm/inch.

Explanation:

Aaron needs to convert 24 inches of copper wire to centimeters. Since 1 inch equals 2.54 centimeters, Aaron can calculate the length of wire needed by multiplying the number of inches by the conversion factor. By performing the multiplication 24 inches × 2.54 cm/inch, the result will give the length of wire needed in centimeters.

To find the answer, complete the multiplication:

24 inches × 2.54 cm/inch = 60.96 centimeters.

Therefore, Aaron needs 60.96 centimeters of copper wire for his experiment.

The greatest common factor of the expression 81x - 27 is;

⇒ 27 (3x - 1)

What is Greatest common factors?

The highest number that divides exactly into two more numbers, is called  Greatest common factors.

Given that;

The expression is;

⇒ 81x - 27

Now,

Solve the expression for the greatest common factor as;

Since, The greatest common factor of the numbers 81 and 27 = 27

So, We take common 27 as;

⇒ 81x - 27

= 3 × 3 × 3 × 3x - 3 × 3 × 3

= 3 × 3 × 3 (3x - 1)

= 27 (3x - 1)

Thus, The greatest common factor of the expression 81x - 27 is;

⇒ 27 (3x - 1)

at this rate, he can eat 15 slices of pizza in 10 minutes **wow!!**

we can do this by setting it up as a proportion: 3slices/ 2 minutes= ?/1 minute

we divide 3 by 2 to get how many slices he can eat in one minute, which is 1.5

so, now, we just have to multiply 1.5 times 10 minutes, and we get 15 slices of pizza per 10 minutes

Hey there!!

Given equation :

... -4 ( x + 10 ) - 6 = -3 ( x - 2 )

Using the distributive property :

... -4x - 40 - 6 = -3x + 6

Combining like terms :

... -4x - 46 = -3x + 6

Adding 46 on both sides :

... -4x = -3x + 52

Adding 3x on both sides :

... -x = 52

... x = -52

3y - 1 < 3

Isolate the y. Treat the less than or equal like an equal sign.

Do the opposite of PEMDAS. First, add 1 to both sides

3y - 1 (+1) < 3 (+1)

3y < 4

Next, divide 3 from both sides

3y/3 < 4/3

y < 4/3

y < 4/3 is your answer

Final answer:

To find out how much candy Byron ate, we multiply the number of candies Mark ate, which is 5, by 7. Byron ate a total of 35 pieces of candy.

Explanation:

The question involves solving a basic multiplication problem to determine how much candy Byron ate if Mark ate 5 pieces of candy and Byron ate 7 times as much. According to the given scenario, we can represent this mathematically as:

Mark ate 5 pieces of candy. Byron ate 7 times as much candy as Mark did. To find out the total pieces of candy Byron ate, we multiply the number of candies Mark ate by 7. Therefore, Byron ate 5 pieces × 7 = 35 pieces of candy.

This arithmetic calculation shows us Byron's total candy consumption during the movie.

To convert 0.012 to a fraction, you multiply by 1000 to get 12/1000 and then simplify it to 3/250. Therefore, 0.012 as a fraction is 3/250.

To convert the decimal 0.012 into a fraction, follow these simple steps:

Write down 0.012 as 0.012/1.

Multiply both the numerator and the denominator by 1000 to get rid of the decimal point:

0.012 x 1000 / 1 x 1000 = 12 / 1000.

Simplify the fraction by finding the greatest common divisor (GCD) of 12 and 1000, which is 4:

(12 ÷ 4) / (1000 ÷ 4) = 3 / 250.

Thus, 0.012 as a fraction is 3/250.

1 USD = 1.38 AUD, or its reciprocal

Where,

1.38 recent currency rate

AUD = Australian dollar

USD = US dollar

So, by rearranging

[tex]1 AUD = 1/1.38 USD[/tex]

Then

[tex]22AUD/1.38 = 15.94 USD[/tex]

The answer is

[tex]22A UD = 15.94 USD[/tex]

1/11 is half of 2/11.  (1/11 + 1/11 = 2/11)

As 2/11 = 0.18, 1/11 must equal half of 0.18.

Half of 0.18 is 0.09.  Thus the decimal for 1/11 is 0.09.

Answer:

The decimal for 1/11 is 0.09

Step-by-step explanation:

We have two options to get the answer, the first one is when we know that 1/11 is half of 2/11, so 1/11 will be half of 0.18. We have to divide 0.18 by 2:

0.18÷2 = 0.09

The other way to do it is to divide 1÷11 = 1/11

The answer is 0.09
