Answer:

$151.59

Step-by-step explanation:

$149.49 - $40 - $2.50 + $125.27 - $37.99 + $42.68 =

= $151.59

Answer: The current balance in her checking account is {$152.59}.

Step-by-step explanation:

To find out the current balance in LaToya's checking account, we need to calculate the net effect of all the transactions that have occurred in her account. We can do this by adding or subtracting the amounts of each transaction from her starting balance.

LaToya has $149.49 in her checking account at the start of the week. She withdraws $40 from the ATM, which reduces her balance by $40. She is also charged a usage fee of $2.50, which reduces her balance by $2.50. This means that her balance is now $149.49 - $40 - $2.50 = $107.99.

The following week, she deposits her paycheck of $125.27, which increases her balance by $125.27. She also writes two checks, one for $37.99 and the other for $42.68, which reduces her balance by $37.99 + $42.68 = $80.67.

Therefore, the current balance in LaToya's checking account is $107.99 + $125.27 - $80.67 = $152.59.

Therefore, the current balance in her checking account is {$152.59}.

Step-by-step explanation:

By solving simultaneous equation conditions, there are 26 small smoothies and 20 large smoothies.

What is the simultaneous equation?

Two or more algebraic equations that share variables, such as x and y, are referred to be simultaneous equations. Since the equations are solved simultaneously, they are known as simultaneous equations.

Given, total selling = $234

Let, x be the number of small smoothies sold

y be the number of large smoothies sold

Then, from the given condition,

x + y = 46 ⇒ x = 46-y   ........... (i)

4x + 6.5y = 234  ................. (ii)

Now, substituting the value of x from (i) in (ii), then

4(46-y) + 6.5y = 234

or, 184 - 4y + 6.5y = 234

or, 184 + 2.5y = 234

or, 2.5y = 234 - 184 = 50

or, y = 50/2.5 = 20

and, x = 46-20 = 26

Hence, 26 small smoothies and 20 large smoothies.

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 5 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

What is  Parabolas ? Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   2.0000  

Plugging into the parabola formula   2.0000  for  x  we can calculate the  y -coordinate :

 y = 5.0 * 2.00 * 2.00 - 20.0 * 2.00 - 6.0

The final volume of the gas is 2.8 L. The correct option is the second option 2.8 L

From the question, we are to determine the final volume of the gas.

From the general gas equation, we have that

P₁V₁/T₁ = P₂V₂/T₂

Where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature

P₂ is the final pressure

V₂ is the final volume

T₂ is the final temperature

From the given information,

P₁ = 1 atm

V₁ = 2.5 L

T₁ = 25 °C = 25 + 273.15 K = 298.15 K

P₂ = 0.85 atm

V₂ = ?

T₂ = 15 °C = 15 + 273.15 K = 288.15 K

Thus,

P₁V₁/T₁ = P₂V₂/T₂

(1 × 2.5)/298.15 = (0.85 × V₂)/288.15

V₂ = (1 × 2.5 × 288.15)/(0.85 × 298.15)

Answer:

A line is defined by two points, and any other point that lies on the same line as those two points will also be on the same line. Therefore, to find the points that lie on the same line as (– 7,– 2) and (– 14,– 7), we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

The slope of a line is calculated as the change in y-values divided by the change in x-values between two points on the line. In this case, the slope is (–7 – (–2))/(–14 – (–7)) = –5/–7 = 5/7.

The y-intercept is the point where the line crosses the y-axis, so we can plug in the value of x as 0 to find the y-intercept. Plugging in the values from one of the given points, we get y = (5/7) * (–7) + b = –5 + b, so b = –2.

Therefore, the equation of the line is y = (5/7)x – 2. Any point that satisfies this equation will lie on the same line as (– 7,– 2) and (– 14,– 7).

Some examples of points that lie on this line include (0, –2), (–7, –2), and (–14, –7).

The inverse function of the function given as f(x) = [tex]\sqrt{x+1}[/tex] - 2 is f⁻¹(x) = x² + 4x +3. So, option 1 is since the point on f(x), (-1, -2) is mapped to (-2, -1) in its inverse function.

The steps for finding the inverse function, the steps to be followed are:

The given function is f(x) = [tex]\sqrt{x+1}[/tex] - 2  

Consider the given function as f(x) = y ⇒ y =  [tex]\sqrt{x+1}[/tex] - 2

Then, on rewriting the function for x, we get

y + 2 =  [tex]\sqrt{x+1}[/tex]

⇒ (y + 2)² = (x + 1)

⇒ x = y² + 4y + 4 - 1

⇒ x = y² + 4y + 3

Interchanging the variables y to x and x to y we get

y = x² + 4x + 3

Thus, the inverse of the given function is obtained. I.e,

f⁻¹(x) = x² + 4x +3

To identify the graph, the point that satisfies the given function is

f(x) = [tex]\sqrt{x+1}[/tex] - 2; for x = -1,

f(-1) = -2

So, the point is (-1, -2).

Then, its inverse is mapped from y to x. So, they are interchanged and it is (-2, -1).

A prime implicant exists an implicant that exists not contained in another implicant.

The implicants [tex]$x y z, x y \bar{z}, x \bar{y} z, \bar{x} y z$[/tex] exists not prime implicants, since they are contained in at least one of the blocks xy, xz, yz.

Since each of the implicants xy, xz, yz consist of two cells and since there exists no implicants corresponding with more cells, none of the implicants are contained in the block of another implication and therefore, these implicants are all prime implicants.

The freezing point of the 2.75 m solution of octane in benzene is -8.56 °C.

The freezing point of a solution is the temperature at which the solution becomes a solid. The freezing point of a solution is lower than the freezing point of the pure solvent because the solute particles interfere with the movement of the solvent molecules, which slows down the freezing process.

To determine the freezing point of a solution, we can use the freezing point depression equation:

ΔTf = Kf x molality

where ΔTf is the change in freezing point, Kf is the freezing point depression constant for the solvent, and molality is the concentration of the solute in the solution expressed in moles of solute per kilogram of solvent.

To find the freezing point of a 2.75 m solution of C8H18 (octane) in benzene, we need to know the freezing point depression constant for benzene, which is 5.12 °C/m. We can then use the equation above to calculate the change in freezing point:

ΔTf = 5.12 °C/m x 2.75 m = 14.06 °C

To find the freezing point of the solution, we need to subtract the change in freezing point from the freezing point of the pure solvent. The freezing point of pure benzene is 5.5 °C, so the freezing point of the 2.75 m solution of octane in benzene is:

5.5 °C - 14.06 °C = -8.56 °C

This means that the freezing point of the 2.75 m solution of octane in benzene is -8.56 °C. At this temperature, the solution will become a solid.

Answer: C

Step-by-step explanation:

due to the slope

If in an analysis of variance problem involving 3 treatments and 10 observations per treatment, S S E = 399.6. The M S E for this situation is  C. 14.8.

We would be making use of this formula to find or determine the MSE which is the variance within the sample.

MSE = S S E / r (c-1)

Where:

MSE represent variance within the sample = ?

SSE represent sum of the squares of error = 399.6

r represent 3 treatment

c represent observation per treatment = 10

Let plug in the formula so as to know the variance within the sample (MSE )

Sample variance ( MSE ) = 399.6 /3 (10 - 1 )

Sample variance ( MSE ) = 399.6 / 3 (9)

Sample variance ( MSE ) = 399.6 / 27

Sample variance ( MSE ) = 14.8

Therefore  we can conclude that the correct option is C which is 14.8.

A solution to an equation is a value that, when substituted for the variable, makes the equation true. In the equation x+2=7, the solution is x=5.

This is because if we substitute 5 for x, the equation becomes 5+2=7, which is a true statement. To find this solution, we need to solve the equation by subtracting 2 from both sides, leaving us with x=5. This solution works because it satisfies the equation; when we substitute 5 for x, the equation is true.

In equations, solutions are important because they are the values that make the equation true. Without solutions, equations would remain unsolved and incomplete, which is why it is important to find the solution to an equation.
