An older person is three years older than eight times the age of a younger person. The sum of their age is 21. Find their ages.

Answers

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.

You invested a total of $9000 at 4.5% and 5% simple interest. During one year, the two accounts earned $425.
How much did you invest in each account?

Answers

eg. the first loan is x, the second loan will be (9,000 - x)

First, we need to make an equation based on the problem

first interest + second interest = 492

5% of x + 6% of (9,000 - x) = 492

This is the equation

Second, solve the equation and find out the value of x (first loan)

0.05x + 0.06(9.000 - x) = 492

0.05x + 540 - 0.06x = 492

-0.01x + 540 = 492

-0.01x = 492 - 540

-0.01x = -48

x = -48/-0.01

x = 4,800

Third, find the second loan

9,000 - x

= 9,000 - 4,800

= 4,200

SUMMARY

The first loan that has interest of 5% is $4,800

The second loan that has interest of 6% is $4,200

How many bit strings of length 10 do not contain the substring 00? In other words, how many strings of length 10, consisting only of 1 and 0, in which there are no two consecutive zeros?

(In response, write down only the number without spaces.)

Answers

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.

Answers

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

What is the perimeter of a rectangle?

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.

Answers

Answer:

The y intercept is 92, this is because:

In slope intercept equations, it is formatted like:

where y is the dependent variable and x is the independent variable

m is the slope

Answers

It’s true

21:35 simplifies to 3:5 when divided by 7 on both sides

24:40 also simplifies to 3:5 when divided by 8 on both sides

Hope that helps!

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.
