Answer: 4.8
Hope this helped!
Brady, Dana, Elijah, and Gianna took part in the school play. Before the start of the play, they each guessed the number of people who would come to see the play. Brady guessed 292 people, Dana guessed 325 people, Elijah guessed 340 people, and Gianna guessed 371 people. It turned out that Dana's guess was the closest, Elijah's guess was the second closest, and Brady's guess was the farthest from the actual number. What is the actual number of people who came to see the play?
Answer:
332
Step-by-step explanation:
Since Dana had the closest guess with 325 people and Elijah had the second closest guess with 340 people we know that the actual number of guests is close to these values. Since Brady had the farthest guess then that means that the actual number of guests is higher than 325 and lower than 340. Therefore the actual number of guests can only be 332 as it is between Dana and Elijah's guesses but still favoring Dana, and also being farthest from Brady's guess.

A radioactive substance decays exponentially. A scientist begins with 150 milligrams of a
radioactive substance. After 40 hours, 75 mg of the substance remains. How many milligrams will
remain after 60 hours?
Answer:
We are given
Scientist begins with 150 milligrams of a radioactive substance
so,
we can use formula
we can plug Po=150
After 29 hours, 75 mg of the substance remains
so, at t=29 , P=75
we can plug it
now, we can solve for k
now, we can take ln on both sides
now, we can plug it back
and we get
we can plug t=33
we get

Step-by-step explanation:
explain the benefits of each of the three forms of quadratic equations, standard form, vertex form, and factored form. What do they reveal about the graph or the quadratic?
Answer:
Summary:
Standard form allow us to quickly find the y-intercept.
Vertex form allow us to quickly locate the vertex.
And factored form allows us to quickly determine the roots/zeros.
Step-by-step explanation:
The three forms of quadratics are the standard form, vertex form, and the factored form. Each of them reveals a specific part about the quadratic.
Standard Form:
The standard form of a quadratic is:
[tex]ax^2+bx+c[/tex]
There are only two details that can be conveyed by a quadratic in standard form immediately: (1) the leading coefficient a, and (2) the y-intercept.
The leading coefficient a will tell us if the parabola curves upwards or downwards.
And the constant c will give us the y-intercept.
Vertex Form:
The vertex form of a quadratic is:
[tex]a(x-h)^2+k[/tex]
There are also two details that can be conveyed by a quadratic in vertex form: (1) the vertex, and (2) the leading coefficient.
The leading coefficient is given by a. Again, this tells us the orientation of the parabola.
And the vertex is given by (h, k).
Hence, in my opinion, vertex form is the best form of a quadratic since it immediately reveals the vertex, the most important aspect of a quadratic.
Factored Form:
The factored form of a quadratic is:
[tex]a(x-p)(x-q)[/tex]
Where p and q are the zeros/roots/solutions of the quadratic.
Again, factored form gives us two details about the quadratic: (1) the leading coefficient, and (2) the zeros.
The zeros tells us when the parabola crosses the x-axis, which can assist in graphing.
Summary:
Therefore, each form of a quadratic equation has its own benefits.
Standard form allow us to find the y-intercept.
Vertex form allow us to quickly locate the vertex.
And factored form allows us to quickly determine the roots/zeros.
Hence, depending on the question, each form can be useful in its own way.

AYUDA PLIS 1) Pablo compro un sobre de jugo que les costo $28,85, un alfajor por $85,50 y un helado. Si pago con $250 ¿Cuánto costo el helado? 2) Santiago compro una bolsa de alimentos para perros a $349,50, otra para gatos a $108,25 y pieritas sanitarias a $ 29,75. a- ¿Cuánto dinero gasto? b- Si pago con $600 ¿Cuánto le dieron de vuelto?
Answer:
1) El helado costó $135,65.
2) a) Gastó en total $487,5. b) Le dieron $112,5 de vuleto.
Step-by-step explanation:
1) Podemos encontrar el costo del helado como sigue:
[tex] T = J + A + H [/tex]
[tex] H = T - J - A = 250 - 28,85 - 85,50 = 135,65 [/tex]
Por lo tanto, el helado costó $135,65.
2) a) Para saber cuanto dinero gastó debemos sumar todos los precios:
[tex] T = B_{p} + B_{g} + P = 349,50 + 108,25 + 29,75 = 487,5 [/tex]
Entonces, gastó en total $487,5.
b) Si pagó con $600, su vuelto fue:
[tex] V = 600 - T = 600 - 487,5 = 112,5 [/tex]
Le dieron $112,5 de vuleto.

Using the feasible region below, determine which x and y values will maximize the profit, P, in the equation P = 40x + 55y * 1 point
A(0, 500)
B(300, 400)
C(380, 200)
D(400, 0)
E None of the Above
Answer:
B (300, 400)
Step-by-step explanation:
The profit maximization will be when the sum of the products will be greater. The maximum profit will be when x is 300 and y is 400. If we put in the equation :
P = 40x + 55 y
A - When x = 0 , y = 500
P = [40 * 0] + [55 * 500]
P = 27500
B -
When x = 300 , y = 400
P = [40 * 300] + [55 * 400]
P = 34000
C -
When x = 380 , y = 200
P = [40 * 380] + [55 * 200]
P = 26200
D -
When x = 400 , y = 0
P = [40 * 400] + [55 * 400]
P = 16000

Every Halloween, trick-or-treaters love going to Gabe's house to see his spooky decorations and get some of his delicious caramel chews. Gabe gives a group of 3 kids a total of 6 caramel chews. He gives a group of 5 kids 10 caramel chews. In this relationship, x represents the number of kids in a group, and y represents the total number of caramel chews Gabe gives to that group.
Answer:
y = 2x
Step-by-step explanation:
Since we are told what to find, we can find the equation of the line that models the statement.
Using the equation of a line
y = MX+c.
m is the slope
c is the intercept
x represents the number of kids in a group (slope)
y represents the total number of caramel chews Gabe gives to that group.
If Gabe gives a group of 3 kids a total of 6 caramel chews and he gives a group of 5 kids 10 caramel chews, we can represent this as coordinate points;
(3,6) and (5,10)
Get the slope
M = 10-6/5-3
M = 4/2
M = 2
Get the intercept by substituting m= 2 any of the points (let's use (3,6)) into the expression y = MX+c to get the value of c;
y = MX+c
6. = 2(3)+c
c = 6-6
c = 0
Substitute m = 2 and c = 0 to get the required equation
y = MX+c
y = 2x+0
Hence the equation that models the statement is y = 2x

f(x)=-3x • G(x) = x +7
Answer:
-3x^2 - 21x
Step-by-step explanation:
This question is representing multiplying two functions :
We are finding f(x) * g(x)
We know that f(x) is -3x and g(x) is x + 7, therefore :
(-3x)(x + 7)
Follow FOIL :
First :
(-3x)(x)
-3x^2
Outer :
(-3x)(7)
-21x
Therefore the answer is :
-3x^2 - 21x

8. The high school FFA is selling fruit. Together, Kay and Ayan sell a total of 25 boxes. Kay sells 13 less than Ayan.
How many boxes does each girl sell?
Define your variables:
X =
Y =
boxes.
boxes, and Ayan sold
Kay sold
Answer:
Kay sold 6 boxes and Ayan sold 19 boxes
Step-by-step explanation:
Let x be the number of boxes sold by Kay and
Let y be the number of boxes sold by Ayan
Then according to given statements, the equations will be:
[tex]x+y = 25\ \ \ Eqn\ 1\\x = y-13\ \ \ Eqn\ 2[/tex]
Putting x = y-13 in equation 1
[tex]y-13+y = 25\\2y-13=25\\2y=25+13\\2y = 38\\\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]
Putting y = 19 in equation 2
[tex]x = 19-13 = 6[/tex]
So we get x=6 and y=19
Hence,
Kay sold 6 boxes and Ayan sold 19 boxes

The length of the base of an isosceles triangle is x. The length of a leg is 4x -3. The perimeter of the triangle is 66. Find x
Answer:
x = 8
Step-by-step explanation:
Since the triangle is isosceles then the 2 legs are congruent.
Given the perimeter is 66, then sum the 3 sides and equate to 66, that is
x + 4x - 3 + 4x - 3 = 66 , that is
9x - 6 = 66 ( add 6 to both sides )
9x = 72 ( divide both sides by 9 )
x = 8
Can someone please explain ASA triangle congruence? I will give brainliest.
Answer:
This is easier to explain with pictures, but I'll try here. The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
