Answer:

The value of a is [tex]a=\frac{K}{4+9b}[/tex].

Step-by-step explanation:

The given equation is

[tex]K=4a+9ab[/tex]

We have to solve the above equation  for a. So, we need to isolate the variable a.

Taking out a from the left side.

[tex]K=a(4+9b)[/tex]

Divide both sides by 4+9b to get the value of a.

[tex]\frac{K}{4+9b}=\frac{a(4+9b)}{4+9b}[/tex]

Cancel out the common factors from numerator and denominator.

[tex]\frac{K}{4+9b}=a[/tex]

Therefore the value of a is [tex]a=\frac{K}{4+9b}[/tex].

4x + 5y = 2(x + 3y)

4x + 5y = 2x + 6y   distributed 2 on the right side

2x + 5y = 6y           subtracted 2x from both sides

2x = y                      subtracted 5y from both sides

         if y = 2x

then 17(y) = 17(2x)

          17y = 34x

Answer: 34x

Let f(n) represent the number of bottles in the store on n-th week.

When n=0, f(n)=250.

Then  40% of the bottles were sold, this means that were sold 250·0.4=f(n)·0.4. The amount of bottles left is 250-250·0.4=f(n)-f(n)·0.4=f(n)·0.6.

If 48 new bottles arrived in shipments, then the amount of bottles became

f(n)·0.6+48=f(n+1).

Since n>0, then

f(n)=f(n-1)·0.6+48.

Answer: correct choice is A.

Option: A is the correct answer.

         A:    f(n) = f(n − 1) ⋅ 0.6 + 48, n > 0    

It is given that:

A store had 250 bottles of water.

Each week, 40% of the bottles were sold and 48 new bottles arrived in shipments.

This means that the number of bottles that will be present in the store after 40% of the bottles will be sold at a particular week= 100%-40%=60% plus 48 new arrival

This means that each time the number of bottles in the store will be 60% of the bottles that were sold previous week plus 48.

        Hence, if f(n-1) represent the number of bottle in the (n-1)th week then the number of bottles in the nth week will be represented by:

                     [tex]f(n)=60\%\ of\ f(n-1)+48\\\\i.e.\\\\f(n)=0.6\cdot f(n-1)+48[/tex]

(3.5x10^-5) (3x10^-10)

Lets break this problem up so that we can answer it more smoothly!

This question can be answered with PEMDAS. 1. Parenthesis, 2. equation, 3. multiplication, 4. division, 5. addiction, and 6. subtraction. As I listed the PEMDAS formula in order, we see that parenthesis comes first.

So,

(3.5x10^-5)

35^-5= 0.000035.

So, we have the first parenthesis equation solved, we will have to multiply the equation we just solved with the next equation because 2 parenthesis' together create a multiplication. For an example, 3(4) would be 12.

(3x10^-10)

30^10= 3e-10

0.000035x3e-10=1.05e-14

Your answer is:

1.05e-14

Answer:

length = 100 yd, width = 60 yd

Step-by-step explanation:

To solve this problem, you must set up an equation.

We know that he length (l ) is 40 yards greater than the width (w ). That means that the length is equal to the width + 40 yards, which can be written as l = w + 40. If the area of the field is 6000 square yards, that means the length times the width must be equal to 6000. Here is the equation that comes from it:

w * (w + 40) = 6000

You can simplify that even further:

w ^2 + 40w = 6000

Divide both sides by 40 to get rid of the coefficient:

w ^2 + w  = 150

Now subtract w from both sides, then take the square root of both sides:

w = sqrt(150-w)

You could keep simplifying this equation until you finally arrive at your answer:

w = 60.

This means that the length, which is 40 more than the width, is 100.

If you want to prove this answer, just multiply the width by the length, which is 60*100, which gives you 6000 square yards; just what you need!

The value of dimensions of the soccer field, in yards are,

⇒ w = 60, l = 40

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

A school is building a rectangular soccer field that has an area of 6000 square yards.

And, The soccer field must be 40 yards longer than its width.

Let width of soccer field = w

Hence, Its length = w + 40

So, We get;

w (w + 40) = 6000

w² + 40w - 6000 = 0

w² + 100w - 60w - 6000 = 0

w (w + 100) - 60 (w + 100) = 0

w = - 100

w = 60

Since, Dimension are always positive.

Hence, w = 60

So, The value of dimensions of the soccer field, in yards are,

⇒ w = 60

l = 60 + 40 = 100

Interesting problem.

A palindrome is a number which is identical when read/interpreted left-to-right or right-to-left.   For example, 14241 is a palindrome, so is 444444.

A three digit palindrome must be made up of two distinct digits only, one for the first and last digits, and one for the middle, for example, 424, or 515, etc.

For a number to be divisible by 9, the sum of the digits must add up to a multiple of 9, such as 0, 9, 18, 27, etc.

We can now form a table of the possible 3-digit palindromes divisible by 9, starting with the first/last digits (=A), and finding the middle digit (=B).  The number is therefore represented by the pattern ABA.

For example, when A=1, we have the number 1B1.  For the number to be divisible by 9, B=7 so that sum=1+7+1=9, which is divisible by 9.

For each value of A (from 1 to 9) we can only find one value of B that makes the number divisible by 9.   Thus we can only find nine such numbers, with A equal to 1 to 9.

Here's a list of the numbers

A   B   number

1    7    171

2   5    252

3   3    333

4   1     414

5   8    585

6   6    666

7   4    747

8   2   828

9   0   909

There are 9 unique 3-digit palindromic numbers that are divisible by 9. This is determined by the rule that a number is divisible by 9 if the sum of its digits is also divisible by 9, considering the constraints of palindromic numbers.

To find 3-digit palindromic numbers that are divisible by 9, we must first understand what qualifies as a palindromic number. A palindromic number is a number that remains the same when its digits are reversed. For a 3-digit number, this means the first and last digits must be the same (i.e., the form is aba, where a and b are digits).

Since our objective is to find those divisible by 9, we must recall the divisibility rule for 9: a number is divisible by 9 if the sum of its digits is also divisible by 9. For a 3-digit palindromic number aba, the sum of its digits is 2a + b. For this sum to be divisible by 9, a and b must be chosen accordingly.

The smallest 3-digit palindromic number is 101, and the largest is 999. To be divisible by 9, the sum of the digits must equal 9, 18, 27,..., or 81 (the largest sum for a 3-digit number where the first and last digits are the same). Since there are 9 possible sums (9 to 81 inclusive), and each sum offers a unique number that satisfies the palindrome and divisibility criteria, there are 9 such numbers.

Therefore, there are 9 unique 3-digit palindromic numbers divisible by 9.

The diagonals of a rectangle are congruent. That means that their lengths are equal. One diagonal is AC, and the other diagonal is BD. AC must equal BD. We set their lengths equal and solve for x.

3(x - 2) = x + 18

Distribute the 3 on the left side.

3x - 6 = x + 18

Subtract x from both sides; add 6 to both sides.

2x = 24

Divide both sides by 2.

x = 12

Now that we know x = 12, we replace x with 12 in BD = x + 18 to find the length of BD.

BD = x + 18 = 12 + 18 = 30

Since the diagonals are congruent, the length of AC is also 30.

Answer:   AC = 30;  BD = 30

The length of the diagonals of the rectangle are AB = 30 and BD = 30

A 4-sided flat shape with straight sides where all interior angles are right angles (90°). Also, the opposite sides are parallel and of equal length.

Given that, ABCD is a rectangle and its diagonals are  AC= 3(x-2) and BD=x+18

According to the property of a rectangle,

Diagonals of a rectangle are equal.

Therefore, AC = BD

3(x-2) = x+18

3x-6 = x+18

2x = 24

x = 12

AC = 3(12-10) = 30

BD = 12+18 = 30

Hence, the diagonals of the rectangle are AB = 30 and BD = 30
