well, from 273 to 250 is 23 bucks, so that's the difference.
we know 273 is the original price, or namely the 100%, so what's 23 bucks off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 273&100\\ 23&x \end{array}\implies \cfrac{273}{23}=\cfrac{100}{x}\implies \implies 273x=2300 \\\\\\ x=\cfrac{2300}{273}\implies x\approx 8.42[/tex]

9th grade- Point slope of line. Please explain how to do this, I got it wrong. I need an explanation cause I haven’t done it in a while.
Answer:
C) y -2 = 5/2(x -2)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
__
For slope m = 5/2 and point (2, 2), the equation is ...
y -2 = 5/2(x -2) . . . . . . matches choice C
_____
Additional comment
One way to tell if you have the correct answer is to see if the given point satisfies the equation.
A) 2 +2 = 5/2(2 +2) ⇒ 4 = 10 . . . false
B) 2 +2 = -5/2(2 -2) ⇒ 4 = 0 . . . false
C) 2 -2 = 5/2(2 -2) ⇒ 0 = 0 . . . true
D) 2 +2 = 5/2(2 -2) ⇒ 4 = 0 . . . false
If you were to get a "true" for more than one, then you can try another point at (h +1, k +m).
__
Using this form, you are essentially translating the line y = mx so it goes through the point (h, k), instead of (0, 0).
Consider the right triangle below. A right triangle with a hypotenuse with length 6.5 feet, and side lengths of 2.5 feet and 6 feet. What is the perimeter and area of the given triangle
Step-by-step explanation:
the perimeter is the easiest, really. we only need to add all side lengths. there is nothing else to the perimeter calculation.
so,
perimeter = 6.5 + 2.5 + 6 = 9 + 6 = 15 ft.
area is also relatively easy for right-angled triangles, because the sides that enclose the 90° angle, act also as height of the triangle to each other.
so, it is a half-rectangle, and we only need to multiply these 2 sides (not including the Hypotenuse) and divide this by 2.
area = 6×2.5/2 = 3×2.5 = 7.5 ft²

Please help me solve this problem please and thank you
Answer:
y = 0
x = 8
Step-by-step explanation:
subtract second equation from first one
3x - 6y - (3x - y) = 24 - 24 the - sign in front of the parenthesis effects the inside expressions
3x - 6y - 3x + y = 24 - 24 add/subtract like terms
-5y = 0 and so y = 0
to find the value of x we can use this information
3x - y = 24 since y = 0
3x = 24 divide both sides by 3
x = 8

Keisha decides to roll a number cube until she gets a 6. Let X = the number of rolls until she rolls a 6.
What is the probability that Keisha gets her first 6 on or after her 2nd roll?
Round to 3 decimal places.
10 037
Answer: 0.833
Step-by-step explanation: edge 2022 :)
The probability of getting 6 in second roll is 0.1388 and on 3rd roll is 0.1157.
What is probability?The mathematical discipline of probability is concerned with numerical descriptions of the likelihood of an event or proposition being true. A number between 0 and 1 indicates the likelihood of an event, with 0 representing impossibility and 1 representing certainty. The more likely it is that an event will occur, the higher its probability. The tossing of a fair (unbiased) coin is an easy illustration.
Given
A fair die is rolled repeatedly until a six is obtained.
The probability of getting a 6 in the second toss is
P(X = 2) = (1 - 1/6)1/6
P(X = 2) = 5/36 = 0.1388
The probability of getting a 6 in the third toss is
P(X = 3) = (1 - 1/6)(1 - 1/6)1/6
P(X = 3) = 5/6 x 5/6 x 1/6
P(X = 3) = 25/216
P(X = 3) = 0.1157
Hence the probability on second roll is 0.1388 and on third roll is 0.1157.

What is the solution to this equation? 7-1^3 √2-x=12
X=5
Answer:
x = 127
Step-by-step explanation:
[tex]7-\sqrt[3]{2-x} = 12[/tex] , add the cube root to both sides and subtract the 12
[tex]7-12 = \sqrt[3]{2-x}[/tex], combine like terms
[tex]-5 = \sqrt[3]{2-x}[/tex], raise both sides to the third power
[tex](-5)^{3} = (\sqrt[3]{2-x} )^{3}[/tex], simplify
[tex]-125= 2-x[/tex] , to isolate the variable subtract 2 from both sides
[tex]-125-2 =-x[/tex], combine like terms
[tex]-127=-x[/tex], multiply both sides by -1

Find the equation of the line
Solve for
0.5(r +2.75) = 3
Please I really need help I’m stuck
Answer:
r=3.25
Step-by-step explanation:
3 divided by 0.5=6
6-2.75=3.25
r=3.25
Answer:
r = 3.25
Step-by-step explanation:
Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions
~
First, divide 0.5 from both sides of the equation:
(0.5(r + 2.75))/0.5 = (3)/0.5
r + 2.75 = 3/0.5
r + 2.75 = 6
Next, subtract 2.75 from both sides of the equations:
r + 2.75 (-2.75) = 6 (-2.75)
r = 6 - 2.75
r = 3.25
r = 3.25 is your answer.
