Trina wants to find the least expensive way to buy 24 necklaces. She wants to buy only one type of package. She has $48. The table shows the number of necklaces in a package and the cost of each package.
Trina should buy the $6 packages to get 24 necklaces for the least price as calculated by using multiplication and division.
A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics .One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The other operations are multiplication, addition, and subtraction.At a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.From the attached table let us calculate the cost of buying necklaces in the various packages by using multiplication and division.
For the $4 package:
Number of necklaces in the package = 3
Number of packages Trina should buy (division used) = 24 ÷ 3 = 8
Cost of 8 packages =$ 4 × 8 = $ 32
For the $5 package:
Number of necklaces in the package = 4
Number of packages Trina should buy(division used) = 24 ÷ 4 = 6
Cost of 8 packages =$ 5 × 6 = $ 30
For the $6 package:
Number of necklaces in the package = 6
Number of packages Trina should buy(division used) = 24 ÷ 6 = 4
Cost of 8 packages =$ 6 × 4 = $ 24
Therefore buying the $24 package is the cheapest.

Reason:
For any 30-60-90 triangle, the long leg is exactly [tex]\sqrt{3}[/tex] times as long compared to the short leg.
In other words,

Answer: f(x)=x^2+2x+1 and g(x)=-x^2+1 ==> 1st option
Step-by-step explanation:
Both are quadratic equations: -x^2 or x^2
Blue graph: x^2 since it's facing up
f(x)=(x-b)^2
Vertex: When x=-1, y=0 ==> 0=(-1+b)^2
0=-1+b
b=1
f(x)=(x+1)^2
f(x)=(x+1)(x+1)
f(x)=x^2+x+x+1
f(x)=x^2+2x+1
Red graph: -x^2 since it's facing down
g(x)=-x^2+b
Vertex: When x=0, y=1 ==> 1=(0)^2+b
1=0+b
b=1
g(x)=-x^2+1

Levi brought a bag containing 50 small candies. He starts eating the candies at a rate of 4 candies per minute. Answer the questions below regarding the relationship between the number of minutes eating and the number of candies left in the bag.
Whoever answers correctly with an detailed explanation will get Brainliest!!!
The independent variable x ,represents minutes and dependent variable is the number of candies eating by Levi because the eating of candies depends on the minutes.
A function relating these variable is Z(x)=4x
So Z(7)=28 meaning In 7 minutes Levi ate 28 candies and number of candies left in the bag is 22.
As given,
Independent variable=x
Dependent variable=Z(x)
Function Z(x)=4x
So, Z(7)=4×7
=28
Candies left in bag =50 -28
=22
Therefore, function relating independent variable x with Z(x)=4x and Z(7)=28 represents number of candies ate by Levi in 7 minutes ,number of candies left in the bag is 22.

What is the probability of rolling either a 5 or a 6 using a normal six-sided die?
1/3 is the probability of rolling either a 5 or a 6 using a normal six-sided die.
Define probability?Probability can be defined as the ratio between the number of favorable outcomes and the total number of outcomes of an event.
Given:
Six-sided dice rolled once
Let n be the number of outcomes
let x be the number of favorable outcomes
We know that,
[tex]Probability=\frac{x}{n}[/tex]
When the six-sided dice roll, The possible outcomes are,
[tex]\{1,\;2,\;3,\;4,\;5,\;6\}[/tex]
Therefore,

Find an equation of the tangent line to the curve at the given point. y = ex cos(x) , (0, 1)
The equation of the tangent line to the curve at the given point is given by: y = x + 1.
What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.Now,
Given:
Equation of line: y = [tex]e^{x}[/tex] cos(x)Given point = (0,1)To find: Equation of a tangent line through the given point.
Finding:
y = [tex]e^{x}[/tex] cos(x)
By product rule of differentiation, y' = [tex]e^{x} sin(x) +e^{x} cos(x)[/tex]
For x = 0, y' (0) = 1 (0) + 1( 1) = 1 = slope of the line
Now, we know: equation of a line is given by:
[tex](y-y_0)=m(x-x_0)[/tex]
For [tex]x_0 = 0 And y_0 = 1[/tex], The equation of the tangent line will be:
=> y - 1 = 1 (x - 0)
=> y - 1 = x
=> y = x + 1
Hence, The equation of the tangent line to the curve at the given point is given by: y = x + 1.

The correct answer for given question is 6.
If every element of a non-empty set X has only one image or range to a non-empty set Y, a relation 'f' is said to be a function.
Or
If 'f' is the function from X to Y and (x,y) f, then f(x) = y, where y is the image of x and x is the preimage of y under function f. It is written as;
f: X → Y.
In accordance with the conditions stated in the question:
f(x) = 3x^2 and g(x) = 4x^3 + 1
The composition of functions is defined as fog(x) = f(g(x)), where the input for the function f(x) is the actual expression of the function g(x) in terms of "x":
f(g(x)) = f(4x^3 + 1)
f(g(x)) = 3(4x^3 + 1)^2
f(g(x)) = 3(4x^3 + 1) (4x^3 + 1)
f(g(x)) = 3(16x^6 + 8x^3 + 1)
f(g(x)) = 48x^6 + 24x^3 + 3
Therefore, the degree of the given expression is 6 (the highest power of the variable ‘x’)

y=-2x+3
The parallel lines are y = 2x + 3 and y = 2x - 5
How to determine the parallel lines?The given equations are linear equations
Linear equations are represented as
y = mx + c
Where the slope of the linear equation is
Slope = m
Linear equations that have the same slope are parallel
This means that y = mx + c and y = mx + b are parallel lines because the slopes of the linear equations is m

ann is 4 years older than Julie. 4 years ago, ann was twice as old as julie. find their present ages
The present ages of Ann and Julie are 12 years and 8 years, respectively.
What are the current ages of Ann and Julie?
Let x, y be the current ages of Ann and Julie, whose features are synthetized in the following linear equations:
Ann is 4 years older than Julie
x = y + 4
x - y = 4 (1)
4 years ago, Ann was twice as old as Julie
x - 4 = 2 · (y - 4)
x - 4 = 2 · y - 8
x - 2 · y = - 4 (2)
Now we proceed to determine the ages of Ann and Julie by solving the system of linear equations: (x, y) = (12, 8)
The present ages of Ann and Julie are 12 years and 8 years, respectively.
