The number of sheets of toilet paper that have not been used is 193473.
What is multiplication?Multiplication simply has to do with the product of numbers.
From the information, the roll had 969696 sheets when it was new and the person used 999 sheets of toilet paper each day for 777 days.
Therefore, the sheet left will be:
= Number in the new roll - Sheets used
= 969696 - (777 × 999)
= 969696 - 776223
= 193473

A state agency recorded the number of each type of flood that occurred in the state from 2016–2020. The results are as follows. If similar proportions of flood types are predicted for the following year, what is the estimated probability that a flood in 2021 in that state will be a river flood? Round your answer to the nearest percent. A. 7%B. 60%C. 20%
The table shows different flood types and their frequencies.
Total frequency of all flood types = 18 + 6 + 4 + 2 = 30
frequency of river flood = 6
Recall, probability is expressed as
number of favorable outcomes/number of total outcomes
Thus, the estimated probability that a flood in 2021 in that state will be a river flood is
6/30 = 0.2
By changing 0.2 to percentage, we have
0.2 x 100 = 20%
The correct option is C. 20%
FIND THE MEASURE OF EACH ANGLE<1 and <2 form a linear pair and m<2= 52 degrees.

The value of question are 65+[tex]\underline{115}[/tex]=180, [tex]11x+\underline{48}=180^o[/tex], [tex]11x=\underline{132}[/tex] and [tex]x=\underline{12}[/tex].
In the given question we have to find the value of missing term.
(1) 65+......=180
(2) 11x+.......=180
(3) 11x=.........
(4) x=........
To solve this question we have to use some theorem.
Firstly solving the first question.
As we know that the angle of straight line is 180[tex]^o.[/tex]
So from the diagram
[tex]65+z=180^o[/tex]
Subtract 65 on both side
[tex]65+z-65=180^o-65[/tex]
[tex]z=115[/tex]
Hence, 65+[tex]\underline{115}[/tex]=180.
Now finding the value of second question.
Using Alternate Exterior Angles Theorem
According to theorem the angle beside 11x - 17 is 65.
As we know that the angle of straight line is 180[tex]^o.[/tex]
So 11x-17+65=180[tex]^o.[/tex]
Simplifying
So [tex]11x+\underline{48}=180^o[/tex]
Now finding the value of third question.
From the second question answer we get [tex]11x+{48}=180^o[/tex]
Now solving this equation to find the value of 11x
Subtract 48 on both side
[tex]11x+{48}-48=180^o-48[/tex]
[tex]11x=132[/tex]
Hence, [tex]11x=\underline{132}[/tex]
Now solving the fourth question.
To find the value of fourth question we further simplify the answer of third question.
[tex]11x=132[/tex]
Divide by 11 on both side
[tex]\frac{11}{11}x=\frac{132}{11}[/tex]
[tex]x=12[/tex]
Hence, [tex]x=\underline{12}[/tex]

Chad doesnt have any money, but he owes his sister $15, owes his brother $9 and owes his friend $24. What integer could be used to represent the amount of money chad has?
Answer:
- 48.00
Step-by-step explanation:
Add all the debt up.
Answer: -48
Step-by-Step Explanation:
Money that Chad owes his Sister = $15
Money that Chad owes his Brother = $9
Money that Chad owes his Friend = $24
Total Money he owes = 15 + 9 + 24 = $48
Hence, Total Money he has = -48 (since he doesn't have any money)
The value of x =5 is a solution to each of the following except which ?
A 3x+2=4x-3
B (x+2)(x-5)=0
C4x+2=15
D 3x-10=x
Answer:
The answer is C
Step-by-step explanation:
If you substitute every x value for 5, you know that every equation can have 5 as an answer but C.
A. 3x+2=4x-3
Isolate the x(s) and combine like terms
3x+2-2=4x-3-2
3x=4x-5
3x-4x=4x-4x-5
-x=-5
-x(-1)=-5(-1)
x=5
Therefore A is a solution
B. (x+2)(x-5)=0
Substitution--Substitute every x for a 5
(7)(0)=0
anything multiplied by 0 will be 0
B. Is a solution because it is true.
C. 4x+2=15
Isolating the x(s) and combine like terms
4x+2-2=15-2
4x=13
4x÷4=13÷4
x=3.25
C is not a solution because x should equal to 5 but in this equation x can only be equal to 3.25. C is wrong.
We know our answer so we don't have to keep solving the rest of the equations.
But I'll just do D
D. 3x-10=x
Isolate the x(s) and combine like terms
3x-x-10=x-x
2x-10=0
2x=10
2x÷2=10÷2
x=5
D is a solution.

Using completing the square method (x + 8)2 = +1 is the intermediary step in the equation (x + a)2 = b after the square is complete.
What is completing the square method?A quadratic problem can be solved using the Completing the Square method. In order to do this, the equation's form must be altered so that the left side is a perfect square trinomial. Finding the roots or zeros of a quadratic polynomial or a quadratic equation is the most frequent use of the completing the square method, which also covers factoring quadratic equations.Get the intermediate step:
-3x² - 35x - 189 = 13x-3x² - 35x -13x- 189 = 0-3x² - 48x- 189 =0Divide the equation by 3 into both sides:
-x² - 16x- 63 = 0x² + 16x +63 = 0Adding 1 on both sides to complete the square:
x² + 16x +63 +1 = 1x² + 16x +64 = 1(x + 8)² = +1Therefore, (x + 8)2 = +1 is the intermediary step in the equation (x + a)2 = b after the square is complete.

For which value of x does the graph of the following function F(x) have a
vertical asymptote?
F(x) =
1
X-11
Answer:
x = 1
Step-by-step explanation:
Horizontal asymptotes are the y-values for which a particular function is undefined;
Finding the horizontal asymptote for linear reciprocal function is quite simple;
For this kind of function, where there is no x term in the numerator, the horizontal asymptote is just equivalent to the constant added to the fraction (note: having no added constant is the same as having an added 0);
so:
f(x) = 1/(x - 1) = (1/( - 1 )) + 0
The horizontal asymptote is y = 0 for this function.
If it was F(x) = (1/(x - 1)) + 1, the horizontal asymptote would be y = 1

What is Geometric Progression?
A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio. For instance, the geometric progression 2, 6, 18, 54,_ _ _ _ has a common ratio of 3.
Given in question,
first term of the GP is 1,
4th term of the GP is 27,
[tex]4^{th} term = ar^3[/tex]
[tex]ar^3 = 27[/tex]
Therefore, the ratio term of geometric progression, r = 3
We know that, [tex]a_n = ar^{n-1}[/tex]
[tex]a_9 = ar^8[/tex]
[tex]a_9 = 3^8[/tex]
a9 = 6561
Therefore, the 9th term of given geometric progression is 6561.
