Answer: 54
Step-by-step explanation: bc ? you just divid 54 by 3 and 6 then you divid 77 by 4 and 9 then divide them both tada
Answer:
sodas cost $5 and a large popcorn costs $8
create formulas out of the situations making the variable p=popcorn and s=soda
so,
3p + 6s = 54
and
4p + 9s = 77
then choose one variable to solve for
3p = 54 - 6s
divide both sides by 3
p = 18 - 2s
then plug your answer for p into the other equation:
4(18 - 2s) + 9s = 77
finally, solve for s
72 - 8s + 9s = 77
s = 5
if s=5 then
3p + 6(5) = 54
p = 8

A chi-square test was conducted to investigate whether there is an association between a person's favorite flavor of ice cream and their favorite toppings. Each of 200 randomly selected customers at an ice cream parlor was asked to pick their favorite flavor from vanilla, chocolate, chocolate chip, or none of these. They were also asked to pick their favorite topping from chocolate sauce, peanuts, crumbled cookies, crushed candies, or none of these. The hypothesis test had a test statistic of 24.97 with an associated p-value of 0.015. If the significance level of the test was a = 0.05, which of the following is the correct decision for this hypothesis test?
A. There is not convincing statistical evidence to suggest an association between favorite ice cream flavor and favorite topping.
B. There is convincing statistical evidence to suggest an association between favorite ice cream flavor and favorite topping.
C. There is convincing statistical evidence to suggest there is not an association between favorite ice cream flavor and favorite topping.
D. There is proof that a person's favorite ice cream topping is dependent on the person's favorite ice cream flavor.
E. There is proof that a person's favorite ice cream topping is independent of the person's favorite ice cream flavor.

Answer:
x = 6.25
Step-by-step explanation:
Suppose y = 2x - 2.5. Find x when y = 10
this gives us the equation:
10 = 2x - 2.5
add 2.5 to both sides
2x = 12.5
divide both sides by 2
x = 6.25

A swimming pool in the shape of a cylinder with a diameter of 10 m and a depth of 3 m is being filled with water. 27,535 L have been added so far. 1 m3 is equal to 1000 L. To the nearest liter, how much more water can the pool hold?
A. 236,000 L
B. 208,084 L
C. 236,616 L
D. 207,314 L
No dam links
Answer:
207,314
Step-by-step explanation:
V = πr2h =π · 52·3 ≈ 235.61945 m^3
because 1m^3 = 1000 L, (27,535 / 1000) = the amount of added water in m^3. As this is equal to 27.535, we can substract this from 235.62.
235.62 - 27.535 is about 208.085, or 207.314 because of rounding. As this is in m^3, we multiply by liters to arrive at the answer of 207,314, or option D.

Which function defines (g•f)?
f(x)= log(5x)
g(x) = 5x + 4
A. (g•f)(x)= 5x log(5x) + 4log(5x)
B. (g•f)(x) = 5x + 4 + log(5x)
C. (g•f)(x) = 5x – 4 – log(5x)
D. (g•f)(x) = 5x log(5x) + 4
Answer:
A
Step-by-step explanation:
A. (g•f)(x)= log(5x) ( 5x + 4)=5x log(5x) + 4log(5x)
The function 5x log(5x) + 4log(5x) defines (g•f)
We have given that,
A. (g•f)(x)= 5x log(5x) + 4log(5x)
B. (g•f)(x) = 5x + 4 + log(5x)
C. (g•f)(x) = 5x – 4 – log(5x)
D. (g•f)(x) = 5x log(5x) + 4
We have to determine which function defines (g•f)
Where f(x)=log(5x) and g(x)=5x+5
What is the multiplication function?
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
A. (g•f)(x)= log(5x) ( 5x + 4)=5x log(5x) + 4log(5x)
(5x+4)(log(5x))=5x(log(5x))+4(log(5x))
Therefore the option A is correct.

The first step in determining the solution to the system of equations, y = –x2 – 4x – 3 and y = 2x + 5, algebraically is to set the two equations equal as –x2 – 4x – 3 = 2x + 5. What is the next step?
Set y = 0 in y = –x2 – 4x – 3.
Factor each side of the equation.
Use substitution to create a one-variable equation.
Combine like terms onto one side of the equation.
Answer:
Last one. Combine like terms onto side of the equation.
Step-by-step explanation:
The first step in determining the solution to the system of equations, [tex]y = -x^2 - 4x - 3[/tex] and [tex]y = 2x + 5[/tex] , algebraically is to set the two equations equal as [tex](-x^2 - 4x - 3) = 2x + 5[/tex], will be to set the equations equal to each other.
What is system of equations ?System of equations comprises of two or more equations of two or more variables and seeks common solutions to the equations.
We have,
[tex]y = -x^2 - 4x - 3[/tex]
[tex]y = 2x + 5[/tex]
So, to determine solution to these System of equations,
We have to
Set the equations equal to each other and solve for the value of [tex]x[/tex],
i.e.
[tex]-x^2 - 4x - 3=2x+5[/tex]
[tex]-x^2-6x-8=0[/tex]
[tex]x^2+6x+8=0[/tex]
[tex]x^2+4x+2x+8=0[/tex]
[tex]x(x+4)+2(x+4)=0[/tex]
[tex](x+2)(x+4)=0[/tex]
⇒ [tex]x+2=0[/tex]
[tex]x=-2[/tex]
[tex]x+4=0[/tex]
[tex]x=-4[/tex]

How do I break it down to slove this problem
Answer:
x = -19
Step-by-step explanation:
first isolate x by subtracting 8 on both sides:
179 = -9x + 8
-8 -8
=> 171 = -9x
then divide -9 on both sides to solve for x:
=> x = 171 ÷ -9 = -19

A rectangle has a perimeter of 42 ft its length, L, is 3 feet more than twice its width, W.
(c) Solve the system of equations that you just created by substitution to find the values of the length and width.
Answer:
Length of rectangle = 15 feet
Width of rectangle = 6 feet
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 ft
Length of rectangle = 2[Width of rectangle] + 3
Find:
Value of length and width
Assume:
Width of rectangle = w
SO,
Length of rectangle = 2[w] + 3
Perimeter of rectangle = 2[l + b]
42 = 2[2w + 3 + w]
2[3w + 3] = 42
6w + 6 = 42
6w = 42 - 6
6w = 36
w = 36 / 6
w = 6
So,
Width of rectangle = 6 feet
Length of rectangle = 2[w] + 3
Length of rectangle = 2[6] + 3
Length of rectangle = 12 + 3
Length of rectangle = 15 feet
