Answer:
Ms. Russell purchased 218 teacher-discount tickets and 133 administrator-discount tickets.
Step-by-step explanation:
Let's start by defining the variables:
Let t be the number of teacher-discount tickets purchased by Ms. Russell.
Let a be the number of administrator-discount tickets purchased by Ms. Russell.
From the problem statement, we know that:
The price of a raffle ticket is $1.00.
Teachers get a 40% discount, so they pay only 60% of the regular price.
Administrators get a 10% discount, so they pay only 90% of the regular price.
Ms. Russell purchased a total of 351 tickets.
Ms. Russell spent a total of $250.50.
We can use these facts to set up a system of two equations:
t + a = 351 (the total number of tickets)
0.6t + 0.9a = 250.50 (the total amount spent, taking into account the discounts)
To solve for t and a, we can use substitution or elimination. Let's use elimination:
Multiplying the first equation by 0.6, we get:
0.6t + 0.6a = 210.6
Subtracting this equation from the second equation, we get:
0.3a = 39.9
Dividing by 0.3, we get:
a = 133
Substituting this value into the first equation, we get:
t + 133 = 351
t = 218
Therefore, Ms. Russell purchased 218 teacher-discount tickets and 133 administrator-discount tickets.

Identify the center and radius of a circle with equation (x-5)^2+(y+3)^2=25
The center and radius of the circle is (5, -3), and 5 respectively.
What is the center and radius of the circle?The standard form equation of a circle with center (h, k) and radius r is:
(x - h)² + (y - k)² = r²
Given the equation of the circle in the question:
( x - 5 )² + ( y + 3 )² = 25
To identify the center and the radius.
Comparing this equation ( x - 5 )² + ( y + 3 )² = 25 to the standard form of a circle equation, which is (x - h)² + (y - k)² = r², we can easily identify the center and radius of the circle.
( x - 5 )² + ( y + 3 )²
(x - h)² + (y - k)² = r²
The center of the circle is given by the values (h, k), which correspond to the opposite signs of the terms inside the parentheses.
In this case, the center of the circle is (5, -3), as we have (x - 5)² and (y + 3)².
The radius of the circle is the square root of the value on the right side of the equation.
In this case, the radius is √25, which simplifies to 5.

Solve for z in equation (z-1)^3+z^3=0
Answer:
z= 1
Step-by-step explanation:
\((z-1)^{3}\) + z^3= 0
\(z^{3} - 3z^{2} +3z-1 + z^{3} =0\)
2z^3 - 3z^2 + 3z - 1 = 0
z(2z^2 - 3z +3) - 1 = 0
z= 1 or 2z^2 - 3z +3= 0
z∈IR
∴z= 1
Answer:
\(z = \frac{1}{2} \\ z = \frac{1 + i\sqrt{3} }{2} \\ z = \frac{1 - i\sqrt{3} }{2} \)
where the last two are needed only over the complex
Step-by-step explanation:
first of all, we can see thay is the sum of two cubes, whixh has a known factorization
\({x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2} )\)
in our case, the expression becomes
\(((z - 1) + z)( {(z - 1)}^{2} - z(z - 1) + {z}^{2} )\)
at this point, since if a product is zero either factor needs to be zero:
if you are to solve over the real numbers, the only factor that contibutes is the first, which gives you\(z = \frac{1}{2} \)
and you're done;
if you want complex solution, we need to handle the second part. it's simple algebra, we just multiply to get\( {z}^{2} - 2z + 1 - {z}^{2} + z + {z}^{2} = 0 \\ {z }^{2} - z + 1 = 0 \\ z = \frac{1 \pm i\sqrt{3} }{2} \)If 45 cookies will serve 15 students, how many cookies are needed for

If a die is rolled one time, find the probability of getting a six.
P(6) = ?
Answer: \(\;\;\frac{1}{6} , \;\; 0.16667,\;\; \text{or about}\;\;17\%\)
Step-by-step explanation:
A regular dice has 6 sides, and only one of those sides side has a six.
We write probability as;
\(\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} = \frac{\text{number of times six is on the dice}}{\text{number of numberss on the dice}} =\frac{1}{6}\)
Hi, there!
_______
\(\boxed{\boxed{\sf{Probability=\dfrac{Favorable \ Outcomes}{Total \ Outcomes}}}}\)
Here,
» Favourable Outcome(s) -> getting a 6 on a die (1 outcome), because only one side of a die has a six on it
» Total Outcomes -> 6 (you can only get 1, 2, 3, 4, 5, 6 if you roll one die)
So,
\(\sf{Probability_{(6)}=\dfrac{1}{6}}\)

The graph of g(x), shown below, resembles the graph of f(x) = x - x2, but it
has been changed somewhat. Which of the following could be the equation
of g(x)?
Anxx
O A. f(x) = (x + 2)4 - (x + 2)2
B. f(x) = x - x2-2
C. f(x) = (x - 2)4 - (x - 2)2
O D. f(x) = x - x2 + 2
Answer:We are given function f(x) = x^4 - x^2.
We need to find the equation of function g(x) according to shown graph.
We can apply rules of transformation to get the function g(x) by using given graph.
Function g(x) graph is being shift a half or 0.5 units up of the graph f(x).
When graph shift k units up, we add k to given function.
Where k is some constant.
In the graph f(x) is being shifted 0.5 units up.
So, we would add 0.5 in f(x) = x^4 - x^2 function.
On adding 0.5 we get
g(x) = f(x)+0.5 = = x^4 - x^2 +0.5.
Therefore, correct option is second option.
g(x) = x^4 - x^2 +0.5.

Step-by-step explanation:
3.1 A family, living in a suburb, has a circular swimming pool with dimensions as shown below. The pool is situated in the middle of the yard and it also has a circular fence around it. The fence is 2 metres from the pool. Depth Dimensions: Diameter 480 cm Diameter You may use the following formulae: Volume of circular pool = × radius × radius depth, where = 3,142 Circumference of the fence = 2 × 7 × radius, where = 3,142 1 m³ 1 000 litre 3.1.1 The capacity of the pool is 30 000 litres. Calculate to the nearest metre the depth of the pool. (7)
Rounded to the nearest meter, the depth of the pool is 2 meters.
Understanding How to Solve Depth ProblemWe can use the formula for the volume of a cylinder (which includes a circular pool) to solve for the depth:
Volume of circular pool = π × radius² × depth
We are given that the capacity of the pool is 30,000 liters. Since 1 m³ = 1,000 liters, we can convert the capacity to cubic meters:
30,000 L ÷ 1,000 L/m³ = 30 m³
Now we can plug in the given diameter of the pool (480 cm) to find the radius:
radius = diameter ÷ 2 = 480 cm ÷ 2 = 240 cm
We can convert the radius to meters:
240 cm ÷ 100 cm/m = 2.4 m
Finally, we can solve for the depth:
Volume of circular pool = π × radius² × depth
30 m³ = 3.142 × (2.4 m)² × depth
Solving for depth, we get:
depth = 30 m³ ÷ (3.142 × (2.4 m)²) ≈ 1.9 m
