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

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.

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.)
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.

Ms. Barnes compared the latest grades of her students with the number of absences they had during the school year leading up to the test. The graph shows the results, with a line of best fit represented by the equation y = 11/3x + 92. 2. What is the y-intercept and what does it mean in terms of the situation ?
Answer:
The y intercept is 92, this is because:
In slope intercept equations, it is formatted like:
y = mx + b
where y is the dependent variable and x is the independent variable
m is the slope
and b is the y - intercept
In terms of this situation, 92 means I think probably the start of their latest grades.

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.

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.
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?
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

Is the statement 21:35 = 24:40 true?give reason
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.
