Answer:
40 inches
Step-by-step explanation:
We know that the height of water in a pool decreased 5 inches per week.
This means that we can form the equation [tex]y=-5x[/tex], since the amount of water remaining is proportionate to the amount of weeks that have passed.
We know [tex]x=8[/tex], since we need to find the change for 8 weeks.
[tex]y = -5\cdot 8[/tex]
[tex]-5 \cdot 8 = -40[/tex]
[tex]y=-40[/tex]
The change will be the absolute value of -40, which just makes it positive, so 40.
Hope this helped!

M (18, 24) is the midpoint of segment JL with J (- 4, - 2). What are the coordinates for L?
Answer:
mid point (x,y) = M (18, 24)
let J (- 4, - 2) be ( x1, y1)
L(a,b) be (x2,y2)
using midpoint formula
(x,y) = [(x1+x2)/2, (y1 + y2)/2]
or, (18, 24) = [(-4+a)/2, (-2+b)/2]
comparing corresponding element we get
18 = (-4+a)/2 24 =(-2+b)/2
or 36 = -4+ a or 48 = -2 +b
or a = 40 or b= 50
L(40,50)

2/3 of the difference of a number t and 8
Answer:
Step-by-step explanation:
Begin at the end. By this I mean to start at the end of that expression and work your way backwards to the beginning. "The difference of t and 8" looks like this: t - 8. "2/3 of" means we are multiplying (the word "of" means to multiply): 2/3(t - 8) is your algebraic translation of that expression.
The required mathematical expression of a statement is 2 / 3 (t - 8 ).
Given that,
To transform the statement into the mathematical form,
2/3 of the difference between a number t and 8
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
given statement,
2/3 of the difference between a number t and 8
implies,
The difference between t and 8 is,
= t - 8
Now the difference is 2/3, now the statement become,
= 2 / 3 (t - 8 )
above equation is the required mathematical expression.
Thus, the required mathematical expression of a statement is 2 / 3 (t - 8 ).

Which graph represents the solution to the inequality?1/3(9x+27)>x+33
Answer:
its c
Step-by-step explanation:
Graph D represents the inequality of the given Equation.
What is inequality?An inequality shows whether one value is less than, greater than, or simply not equal to another value by comparing them.
When two quantities are equal, we use the symbol "=," and when they are not equal, we use the symbol "≠". The first value can either be greater than (>) or less than (<).
Given equation 1/3(9x+27) > x+33
simplify the Equation
multiply both sides by 3 we get,
[1/3(9x+27)] 3 > (x+33)3
9x + 27 > 3x + 99
9x > 3x + 99 -27
9x - 3x > 72
6x > 72
x > 12
the Equation of inequality is x > 12
the line will be more than 12 and in which 12 is not included,
option D follows the required conditions, the empty circle in 12 shows 12 is not included and the line moves towards the positive side.
Hence option D is the correct representation of the given inequality.

Step-by-step explanation:
The die is rigged, so "not 3" is not a possibility. Ruling out those branches of the tree, there are 4 possible outcomes, one of which is the desired outcome. So the probability is 1/4.
A fair die has six sides that are equally likely, so the probability of rolling more than 2 is always 4/6. The outcome of the first roll does not effect the outcome of the second roll.

I’m only solving for x, it’s triangle mid-segment.
Step-by-step explanation:
Hey there!!
I hope you remember that mid-segment theorem, in which it is stated that, line which passes through the midpoint of one side triangle bisects base, are parallel to another side of triangle and that line is half of parallel side. (i.e CB = 1/2 of RT) .
Now, Let's simply solve it.
[tex]cb = \frac{1}{2} \times rt[/tex]
Put their values as given in question.
[tex]x + 19 = \frac{1}{2} \times (x + 29)[/tex]
Simplify them.
2x + 38 = x +29
2x - x = 29 - 38
x = -9.

32
*19
-------
288
320
-------
608
Another way is to realize 19 is nearly 20, multiply 32 by 20 and then subtract 32:
32
*20
------
640
640
-32
-----
608

What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
5x = 3x
Multiply both sides of the expression by (1/x ).
( 1/x ) 5x = ( 1/x )3x
5 = 3
Divide both sides by x.
5x = 3x
5x / x = 3x / x
5 = 3
Therefore, multiply/divide both sides by the same variable expression. The correct option is D.
