The square of 9 less than a number is 3 less than the number. What is the number?

Hey mate!!

Answer

4/7 and 8/14 are equivalent fractions, because they are both equal to 4/7 when they are simplified.

Correct answer is D. 8/14

Hope it helps you!

What even is this ???

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.

 -6   -6  -6   -6     the difference between the numbers is -6

[tex]a_{n} = a_{1} + d(n - 1)[/tex]  ; where a₁ is the first term, d is the difference, and n is the term

[tex]a_{n} = 5 - 6(n - 1)[/tex]

[tex]a_{n} = 5 - 6n + 6)[/tex]

[tex]a_{n} = 11 - 6n[/tex]

f(1) = 5

[tex]a_{1} = 11 - 6(1)[/tex]

      = 11 - 6

       = 5

Answer:

Negative 2.

Step-by-step explanation:

2x -1 would have an outcome of a negative number since 2 is positive and one is negative. if they were both positive numbers or negative numbers then the answer would be positive

 -9.75 + 3.25x

= -3.25(3) + 3.25(x)

= -3.25(3)  -  -3.25(x)     notice they have the same factor of -3.25

= -3.25(3 - x)

The three consecutive odd integers are 23, 25,27

What is Algebraic expression ?

Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.

Let the three consecutive odd integers be x , x + 2 , x+ 4 then,

the sum of these three odd integers is 17 less than four times the smallest integer that is :

x + (x+2) + (x+4) = 4x -17

3x + 6 = 4x -17

4x - 3x  = 6 + 17

x = 23

x + 2 = 25

x +  4 = 27

Therefore, the three consecutive odd integers are 23, 25,27

To order the numbers from least to greatest: -2.8, -1.25 (-5/4), -1.17 (-7/6), 1.3, 1.33 (4/3). Decimal conversion helps compare their values, with negative numbers being smaller than positive ones.

To order the numbers from least to greatest, we need to compare their values. Negative numbers are less than positive numbers, and among negative numbers, the one with the smaller absolute value is greater. We can convert the fractions to decimals to make it easier to compare all the numbers:

Now we order them from least to greatest:

Step-by-step explanation:

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)

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.

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.

The series is A.P. with first term = 44 and common difference = 39-44=-5 = 34- 39

Sum of A.P. is S = n/2(2a+ (n-1)d)

Where a is first term ,d is common difference and n no. Of terms

Here a = 44 ,d= -5 and n = 23

S = 23 /2(2×44+ (23-1)(-5))

S=23/2(88-110)

S = 23/ 2(-22)

S = 23×-11

S = -253

25% is the same is 1/4 of something. So you have to find what 1/4th of 48 is. To do that, just divide 48 by 4. and you get 12.

A 25% payment on a CD player that costs $48 would be $12. Hope that helps!

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

Solution: The function that represents the Grace earning each week is defined as [tex]e(h)=9h[/tex], where [tex]e(h)[/tex] is in dollar and [tex]h[/tex] is the time in hours. domain of the function [tex]e(h)=9h[/tex] is [10,20].

Explanation:

Let, Grace works for h hours per week.

For one hour she get $9.

For h hours she get [tex]\$(9\times h)=\$9h[/tex].

So, the function that represents the Grace earning each week is defined as [tex]e(h)=9h[/tex].

It is given that she works from 10 to 20 hours per week, therefore the value of h lies between 10 to 20. Hence the Grace's earnings for each week is defined as [tex]e(h)=9h[/tex] and the domain of the function [tex]e(h)=9h[/tex] is [10,20].

Let P = Platinum Gym's income (total)

Let M = Platinum Gym's Registration Fee.

Number of people who received free membership registrations = 50

The total income from anyone who had to register was

P = (124 - 50)*M

P = 74 * M

B

Monthly Fee = MF

n = number of months = 6

c = customer base  = 124

Equation

P = Registration Fee (found in A) + n * c * MF

Solution

P = 74*M + 6*124*MC

P = 74M + 744*MC

The question is, do you count the registration fee at the beginning or not? I would.

To divide a number by a 1-digit divisor, simply divide the number by the divisor. For example, 15 divided by 3 is 5, and 21 divided by 7 is 3. Practice makes perfect in this fundamental aspect of mathematics.

I understand you are trying to learn how to divide by 1-digit divisors. It is a fundamental topic in mathematics that you will use many times in the future.

Let's take the numbers 3 and 7 as examples. To divide by 3 or 7, simply take the number you are wanting to divide and divide it by either 3 or 7. For example, if we want to divide 15 by 3, you would simply perform 15 ÷ 3, which results in 5.

Now, if we want to divide 21 by 7, you would do 21 ÷ 7, which gives you a result of 3. It's that simple! Remember, the biggest key to success here is practice. The more you practice these divisions, the better you'll get at them.

Let the width of rectangle= x centimeter

According to condition length =  (x+2) centimeter

As accoding to formula

perimeter of rectangle = 2( lenght +width)

so Perimeter = 2{(x+2) +(x)}     equation 1

Give perimeter = 60cm          equation 2

comparing  equation 1 and equation 2

2{(x+2) +(x)} = 60

Solving   2{2x+2} =60

4x+4 =60  

subtracting 4 both sides

4x= 56

dividing 4 both sides.

x=14  width of rectangle

AS we have assume length = x+2 ⇒ 14 +2

Length =16
