Considering the perimeter of the rectangle, it is found that 44 feet will be needed to go all the way around the room.

The perimeter of a rectangle of length l and width w is given by:

P = 2(l + w)

In this problem, we have that the length and the width, are respectively, given by l = 12 and w = 10, hence:

P = 2(l + w) = 2(12 + 10) = 44.

44 feet will be needed to go all the way around the room.

[tex]\displaystyle h= \frac{2A}{a+b}[/tex]

Step-by-step explanation:

The given formula is:

[tex]\displaystyle A=\frac{h}{2}(a+b)[/tex]

We need to solve the formula for h.

Multiply by 2:

[tex]2A=h(a+b)[/tex]

Divide by (a+b)

[tex]\displaystyle \frac{2A}{a+b}=h[/tex]

The required solution is:

Answer:

B

Step-by-step explanation:

If a=2, then a+5 is still less than 8. This counter example proves that b is not less than 5, but is less than 6.

The counterexample of the given statement is;

⇒ b = 5

Option B is true.

What is Function?

A relation between a set of inputs having one output each is called a function.

The conditions is given as;

If a + b < 8 and a = 2, then b < 5.

Now,

Let b = 5

Then, a + b = 2 + 5 = 7, is less than 8.

But b= 5 is not less than 5.

So, The counterexample of the given statement is;

⇒ b = 5

Option B is true.

Lets have the younger person be x.
The older person will be 8x + 3.

The sum of their ages is 21, so we can get this equation:

x + (8x+3) = 21

9x+3 = 21
Subtract 3 from both sides
9x = 21

x=3 --> The younger person is 3 years old, and now we can substitute that for the older person (8x+3):

(3 * 8) + 3 = 27

The younger person is 3 years old, and the older person is 27.

Answer:

  144

Step-by-step explanation:

For a bitstring of length n, there are Fibonacci(n+2) strings containing no two consecutive zeros. This can be seen by constructing the strings starting with n=1.

1-bit strings: 1, 0 -- 2 strings not containing consecutive 0s

2-bit strings: 11, 10, 01 -- 3 strings not containing consecutive 0s

Note that we have added 1 to all the 1-bit strings, and added 0 only to the string ending in 1.

3-bit strings: 111, 110, 101, 011, 010 -- 5 strings not containing consecutive 0s

Note that these 5 strings consist of all (3) of the 2-bit strings with 1 appended, and all (1) of the 2-bit strings ending in 1 with 0 appended. The number that now end in 0 is the number previously ending in 1.

__

If (x, y) represents the numbers of n-bit strings ending in (0, 1), then the number of (n+1)-bit strings ending in (0, 1) is (y, x+y). That is, the recursive relation is ...

  [tex](x_1,y_1)=(1,1)\\(x_n,y_n)=(y_{n-1},\,x_{n-1}+y_{n-1})\\b_n=x_n+y_n\quad\text{number of n-bit strings without consecutive 0s}[/tex]

For n=1 to n=10, these pairs are ...

  (1, 1), (1, 2), (2, 3), (3, 5), (5, 8), (8, 13), (13, 21), (21, 34), (34, 55), (55, 89)

The sequence of b[n] values is ...

  2, 3, 5, 8, 13, 21, 34, 55, 89, 144

which are the n=3 to n=12 numbers from the Fibonacci sequence.

That is, there will be Fibonacci(12) = 144 10-bit strings with no consecutive 0s.

Answer:

A function is defined as an operation on a number, which gives only one output for every input

while graphing a function, the x-ordinate denotes the input and the y-ordinate denotes the output of the function

Now, lets look at the graph

for the input value '4' , we notice that there are 2 possible outputs. The output can be either 2.5 or -2.5

Since there are multiple outputs for almost every input, this graph cannot denote a function since a function gives only one output

Answer:

x = 10, y = 20

Step-by-step explanation:

7x + 20 + 90 = 180 (adj angle on st line)

therefore x = 10

5x + 2y = 90 (vertically opposite angle)

2y = 40

y = 20

Answer:

Yes. The are equivalent to each other

Step-by-step explanation:

21 : 35

The LCM of these two numbers is 7

When we divide both of them by 7, we're left with 3:5

24 : 40

The LCM of these two numbers is 8

When we divide both numbers by 8, we're left with 3:5

And, 3:5 = 3:5, so we can say 21:35 = 24:40

PS: Also, if we multiply 21 : 35 by 8 and 24 : 40 by 7, we get the same result, i.e 168 : 280 which also proves that they are equivalent.

Answer:   x = 3/4; y = 19/6

Step-by-step explanation:

plug in y = 2/3x + 8/3​ into 4x - 2y = -4

4x - 2(2/3x + 8/3​) = -4

  4x  - 4/3x - 18/3 = -4

        12/3x - 4/3x = -12/3 + 18/3

                    8/3x = 6/3

                    8/3x = 2

                         x = 2(3/8)

                         x = 6/8  = 3/4

plug the x value into y = 2/3x + 8/3

y = 2/3(3/4) + 8/3

y = 1/2 + 8/3

y = 3/6 + 16/6

y = 19/6
