7.86 liters  of purple paint in each container.

volume of red paint is 8.54 liters.

volume of blue paint is 8.31 liters.

Number of container taken is 2 container.

Paint left after equally poured in 2 container.

and we have to find how many liters of paint are in each container.

Volume of RED Paint + Volume of BLUE Paint =  Volume of PURPLE Paint

8.54 liters + 8.31 liters = 16.85 liters.

(16.85/2) - (1.13/2) = 15.72/2

                            =7.86 liters

7.86 liters of purple paint in each container.

The expression that gives the distance, d, between the ships after t hours is d = 25t

From the question, we are to write an expression that gives the distance, d, between the ships after t hours

First, we will determine the distance the ships have traveled after t hours

Using the formula,

Distance = Speed × Time

Thus,

The first ship would have traveled

20 × t miles

= 20t miles

The second ship would have traveled

15 × t miles

= 15t miles

Using the Pythagorean theorem,

The distance, d, between the ships after t hours is

d² = (20t)² + (15t)²

d² = 400t² + 225t²

d² = 625t²

d = √(625t²)

d = 25t miles

Hence, the expression that gives the distance, d, between the ships after t hours is d = 25t

Step-by-step explanation:

The Associative property is not  displayed by any of the given equations.

The associative property of several binary operations in mathematics states that the outcome will not change if the parenthesis in an expression are rearranged.

The order in which the operations are carried out within an expression that has two or more instances of the same associative operator in a row doesn't matter as long as the order of the operands is left untouched.

Examples of associative property :

[tex]{\displaystyle {\begin{aligned}(7+8)+1&=7+(8+1)=9\,\\5\times (3\times 7)&=(5\times 3)\times 7=24.\end{aligned}}}[/tex]

The parentheses were rearranged on each line, but the expression values were left alone. It can be argued that "addition and multiplication of real numbers are associative operations" because this is true for addition and multiplication of all real numbers.

Here 8=8+0 displays additive identity property.

10×1=10 displays multiplicative identity

5+0=5 displays displays additive identity property.

[tex]5\times \frac{1}{5}=1[/tex]  displays multiplicative inverse property.

[tex]3+\frac{3}{4} =3+\frac{3}{4}[/tex]  displays reflexive property.

Hence no equation displays associative property.

1/3 is the probability of rolling either a 5 or a 6 using a normal six-sided die.

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,

[tex]Number\;of\;outcomes,\;n=6[/tex]

[tex]Probability\;rolling\;5\;is\;\frac{1}{6}[/tex]

[tex]Probability\;rolling\;6\;is\;\frac{1}{6}[/tex]

Therefore, Probability of rolling either 5 or 6 is,

[tex]P(5\;or\;6)=\frac{1}{6} +\frac{1}{6}[/tex]

[tex]P(5\;or\;6)=\frac{2}{6}[/tex]

Step-by-step explanation:

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.

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’)

Now,

Given:

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:

For [tex]x_0 = 0 And y_0 = 1[/tex], The equation of the tangent line will be:

Step-by-step explanation:

Given that the total number of seats in an auditorium is modeled by the following equation:where x represents the number of rows of seats.We are to find the number of rows are there in the auditorium with a total of 416 seats.So, we are to find the value of x if f(x) = 416.

Since the number of rows cannot be negative, so the required number of rows in the auditorium is 16.Thus, the number f rows is 16.

The present ages of Ann and Julie are 12 years and 8 years, respectively.

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.
