Answer:

[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:

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

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

Step-by-step explanation:

For 10 people he only would need 3 cups and 1/3 so he does have enough

To find the degree of this function, you would look at the first term of the function, which is 3. So, the degree of this function would be 3.

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.

Answer:

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:

2/5?

Step-by-step explanation:

Answer:

4/10

Step-by-step explanation:

1/5 = 2/10

(if simplifyed your answer would be 2/5)

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:

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.

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

I think the answer you're looking for is -49.05

(longer version: -49.0504)

Answer:

20

Step-by-step explanation:

The input (X) is 10. The output (Y) is 2X Which means 2 times X. So your answer is 2 × 10 which is 20.

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.
