11. It takes 4 hours to type 8 memos. How long will it take to type 56 memos?

Answer:

the 8 pack

Step-by-step explanation:

So to start we should find how much an individual capsule in each is

Well start off by 5.99/8 which will give us 0.74875 per capsule and well round in to 0.75 each to put it in terms of money.

Now we will do 2.85/2 which then gives you 1.425 and well say that's about 1.43 per capsule

Compute the given function

[tex]f(x)=- 3x^{2}-7x-3[/tex]

How the given function is computed?

Let us consider f (-3)

f(-3)= -3(9)- 7(-3) -3

     =-27+21-3

     = -9

Let us consider f (4)

f(4) = -3(16)-7(4)-3

    =-48-28-3

    = - 79

A) f(-3) * f (4)

= (-9) * (-79)

= 711

B) f(-3)  / f (4)

=  (-9) / (-79)

= 9/79 (or 0.11)

Step-by-step explanation:

The mean of the data values is their average.

To obtain the average, find the sum of the data values and then divide the sum by total number of data.

In the given, we have 10 data values. Thus, the mean is as follows.

Therefore, the mean is 5.

After thoroughly calculation, we have come to find that, If equation x² = 25, where x ε z then x = √25 = 5, thus x is 5.

Equation, also known as a statement of equality between two expressions with variable- and/or number-based components. Since equations are essentially questions, efforts to systematically find answers to those questions have been the driving force behind the development of mathematics.

From straightforward algebraic equations that only require addition or multiplication to differential equations, exponential equations that use exponential expressions, and integral equations, there are many different types of equations that range in complexity. Numerous physics laws are expressed using them.

Simultaneously occurring equations, or system of equations Algebra requires the simultaneous solution of two or more equations (i.e., the solution must satisfy all the equations in the system). The quantity of equations must match the quantity of unknowns for a system to have a distinct solution.

We need to solve a system of two variables with two equations, using elimination method.

y=-2x+30 (1)

y=6x+41​ (2)

We are going to multiply first equation by 3, doing so the equation (1) can be written as:

3y = -6x + 90 (1)

Then, we are going to add the last equation to the second equation

3y = -6x + 90 (1)

+ y= 6x + 41​ (2)

4y = 131

y = 131 / 4 Isolating y

y= 131/ 4

Then, we replace y= 131/4 in the first equation and solve for x

The standard form of the quadratic function with vertex (-1,8) and passing through point (0,2) is y = -6(x+1)²+8.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

The standard form of a quadratic equation in vertex form is given as,

y = a(x-h)² + 8

Where (h,k) is the coordinate of the vertex and a is constant.

Given the vertex  (h,k) = (-1,8)

Substitute, vertex, and  (0,2)

2 = a(0 + 1)² + 8

a = -6

Therefore, the equation converts as,

y = -6(x+1)²+8

Hence "The standard form of the quadratic function with vertex (-1,8) and passing through point (0,2) is y = -6(x+1)²+8".

Answer:

Variables are the letters that represent a number. So, it would be the ones bolded here: 3x=12 and y=1/2x-6

The coefficients are next to the variables-the ones being multiplied with the variable. They are bolded here: 3x= 12 and y= 1/2x-6

The constants are the numbers that aren't coefficients or variables. So they are bolded here: 3x=12 and y=1/2x-6

If we have half a dollar, three quarters, eight dimes, six nickels, and nine pennies , then we altogether have $2.44 .

In the question ,

it is  given that

we have half a dollar ,

which means half a dollar = $0.50

we have , three quarters means

we have 75 cents

and 75 cents = $0.75

we have 8 dimes ,

we know that 1 dime [tex]=[/tex] 10 cents

so , 8 dimes = 80 cents

and 80 cents = $0.80

we have six nickels,

we know that 20 nickels = $1

so , 1 nickel = $1/20

and 6 nickel = $ 6/20 = $0.30

we have nine pennies ,

we know that 100 pennies = $1

So ,1 Pennie = $1/100

and 9 pennies = $ 9/100 = $0.09

According to the converse of corresponding angles theorem, the statement that allows Carmen to conclude that lines p and q are parallel is: ∠2 ≅ ∠6.

A transversal is a line that crosses two straight lines. For example, line t is a transversal that crosses the lines p and q in the given diagram above.

Parallel lines are lines that do not meet each other at any point and are of equal distant to each other.

When a transversal intersects two parallel lines, they form angle pairs. One of such angle pairs is, corresponding angles, which are always congruent to each other.

Thus, if corresponding angles are formed and are equal to each other, then the lines they lie on must be parallel lines based on the corresponding angles converse theorem.

Angles 2 and 6 are corresponding angles that are formed by the transversal that intersects lines q and p. If they are congruent angles, then the lines are parallel.

Therefore, Carmen can use the statement, ∠2 ≅ ∠6 to show that lines q and p are parallel.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A ( t ) = 224 - 16t , where t is the number of trips

a)

The amount of money does Ahmad have left in the account after 11 trips on the toll roads be P

Substituting the value of t = 11 in the equation , we get

A ( 11 ) = 224 - 176

A ( 11 ) = $ 48

So , The amount of money does Ahmad have left in the account after 11 trips on the toll roads is $ 48

b)

The number of trips on the toll roads can he take until his account is empty be n

when A ( t ) = 0

224 - 16t = 0

Adding 16t on both sides of the equation , we get

BODMAS

The BODMAS rule is an acronym representing the order of operations in math:

Given calculation:

42 - 6 ÷ 6 - 3 = 40

Following the order of operations, where division comes before subtraction, the current calculation is:

⇒ 42 - 6 ÷ 6 - 3

⇒ 42 - 1 - 3

⇒ 41 - 3

⇒ 38

Therefore, brackets should be added around (6 - 3) to make the calculation correct:

⇒ 42 - 6 ÷ (6 - 3)

⇒ 42 - 6 ÷ 3
