Answer:

$3,659.82

Step-by-step explanation:

Adding to the checkbook those debits and credits not already there brings its balance to ...

... $3045.58 +651.84 -37.60 = $3659.82

Adjusting the bank's balance by the deposits and checks not already there brings its balance to ...

... $4262.92 +220.05 -325.50 -497.65 = $3659.82

Thus, the reconciled accounts will agree on the balance $3659.82.

The reconciled balance for Gregory Co. was $3,659.82 after accounting for all transactions including deposits, outstanding checks, credited note, and bank charges.

The question involves reconciling the checkbook balance with the bank statement balance for Gregory Co. To reconcile the bank balance with the checkbook balance, we need to account for any transactions that have not been reflected in one or the other. We start with the bank statement balance and adjust it for outstanding checks and deposits not reflected on the statement.

Answer:

(3, 8)

Step-by-step explanation:

For x = 3,

. . . y = 2^x

. . . y = 2^3 = 2·2·2 = 8

This is represented by the ordered pair (x, y) = (3, 8).

Answer:

(3,8)

Step-by-step explanation:

Since the answer choices are given we can plug the "x" value and see if it returns the y-value given in the ordered pair (x,y) and so:

[tex]y=2^x[/tex]

Let's use the ordered pair (3,8) meaning that when x=3 y =8 and so:

[tex]y=2^3=2\times2\times2=8[/tex]

[tex]y=8[/tex]

This is correct and so this is a solution, since the solution is unique when x=3 y is always going to return an 8.

Answer:

2.4 * 10^1

Step-by-step explanation:

Divide the two numbers. 4.8 * 10^3 = 4800

4800/200 = 24

Put into scientific notation

24 = 2.4 * 10^1

4.8 * 10^3 is 24 (2.4*10^1) times greater than 200

The total amount raised by the school is 24 times greater than the amount raised by Graham's class.

The amount raised by Graham's class is $200.

The total amount raised by the school is [tex]4.8 * 10^3.[/tex]

To find the number of times greater the total amount raised by the school is compared to Graham's class, we need to divide the total amount raised by the school by the amount raised by Graham's class.

So, we divide 4.8 * 10^3 by 200 to find the number of times greater the total amount raised by the school is compared to Graham's class.

Therefore,

[tex]= 4.8 * 10^3/ 200[/tex]

[tex]= 2.4 * 10^1.[/tex]

Therefore, the total amount raised by the school is 24 times greater than the amount raised by Graham's class.

Answer:

D. The inequality has an equal sign it

Step-by-step explanation:

We use solid lines whenever the inequality contains [tex]\leq[/tex] or [tex]\geq[/tex]. That means it contains an equal sign which means the boundary line is inclusive.

On the other hand when the inequality does not have an equal sign in it we use a dashed line to indicate that all values on the boundary line are not inclusive.

Answer:

31) Second number line

32) False

33) x>2

Step-by-step explanation:

31) Since -6<x has only < sign but no = sign, it will be an open dot on top of -6.

Since x≤2 has = sign, it will be a closed dot on top of 2.

So, second number line is the correct option.

32) x < -5 represents all the numbers to the left of -5 on a number line like -6,-7,-8,-9 etc.

Since 4 is on the right side of -5 on the number line, it won't be a solution of the inequality x < -5.

33) x+3 > 5

Subtracting 3 from both the sides of the inequality, we have

x + 3 -3 > 5 - 3

Cancelling out the +3 and -3 from the left side, we have

x > 2

1. The 2nd number line represents the inequality.

Explanation:

In words, the inequality reads "negative six is less than x, which is less than or equal to two". On the number line, the open circle at negative six means that -6 is not a solution to the inequality: -6 < x. The point at positive two means that positive two is a solution to the inequality: x ≤ 2. Therefore, all numbers greater than -6 and less than or equal to +2 are solutions to the inequality. This is shown on the second number line.

2. False

Explanation:

In words, the inequality reads "x is less than negative five". This means that all numbers less than -5 are solutions to the inequality. Positive four is not less than negative five, so it is not a solution to the inequality.

3. x > 2

Explanation:

To solve the inequality, we have to move all the terms that do not contain x to one side. This inequality is simple because it only requires one step: subtraction.

Solve for x: x + 3 > 5

1. Subtract 3 from both sides to get x by itself:

x + 3 - 3 > 5 - 3

2. Simplify

x > 2

Divide y by x:

150/10 = 15

135/9 = 15

30 /2 = 15

They all equal 15

This means the constant of proportionality would be y = 15x

The answer is C.

Answer:

Option C is correct

y = 15x

Step-by-step explanation:

Direct variation states that:

[tex]y \propto x[/tex]          ......[1]

then, the equation is in the form of:

[tex]y=kx[/tex], where k is the constant of variation.

From the given table :

consider any points;

x = 9 and y = 135

Substitute these in [1] we have;

[tex]135 = 9k[/tex]

Divide both sides by 9 we have;

15 = k

or

k = 15

then, the equation we have; y = 15x

Therefore,  the constant of proportionality for the table and write in the form y = kx is, y = 15x

Answer:

63 tons

Step-by-step explanation:

The problem statement asks for the tons of hay removed from the first pit. It is convenient to let a variable (x) represent that amount. This is said to be 3 times the amount removed from the second pit, so that amount must be x/3.

The amount remaining in the first pit is 90-x.

The amount remaining in the second pit is 75 -x/3.

Since the first pit remaining amount is half the second pit remaining amount, we can write the equation ...

... 90 -x = (1/2)(75 -x/3)

... 180 -2x = 75 -x/3 . . . . multiply by 2

... 105 - 2x = -x/3 . . . . . . subtract 75

... 315 -6x = -x . . . . . . . . multiply by 3

... 315 = 5x . . . . . . . . . . . add 6x

... 63 = x . . . . . . . . . . . . . divide by 5

63 tons of hay were taken from the first pit.

_____

Check

After removing 63 tons from the first pit, there are 27 tons remaining. After removing 63/3 = 21 tons from the second pit, there are 54 tons remaining. 27 is half of 54, so the answer checks OK.

Answer:

$12.47

Step-by-step explanation:

The total charge was ...

... $13.28 +14.25 = $27.53

The change from 2 $20 bills is ...

... 2 × $20 - 27.53 = $40.00 -27.53 = $12.47

The total cost of lunch is $27.53. Ana paid with two $20 bills, which equals $40.00. After Ana gave the two $20 bills, she received $12.47 in change.

The subject area of this question is mathematics, specifically arithmetic involving decimal numbers. To solve this, we first add together the costs of the two lunches, which are $14.25 and $13.28, that result in $27.53. Ana initially pays with two $20 bills, which sums up to $40.00. Now, we subtract the total cost of the lunches from the amount Ana paid with. So, $40.00 - $27.53 gives us $12.47. This tells us that Ana received $12.47 in change back after paying for lunch.

Answer:

The percent increase was 48.7.

Step-by-step explanation:

The absolute increase in enrollment is 1084 - 729 = 355. This corresponds to a relative increase of 355/729=0.487 (relative to Aug 2017). The proportion 0.487, expressed in percent: 48.7%

Depending on your current method to exercise, you could solve this using the proportionality method: 355/729 = x/100, then cross-multiply and solve for x. Same thing.

All are rational.

Any number you can write exactly and completely, or any repeating decimal is a rational number. Any number that can only be written exactly using a symbol, such as π or √2, is an irrational number. Something like √6.25 is rational, because it can be written exactly as 2.5, without the symbol.

The idea of "rational" means the number can be expressed as the ratio of two integers. Any integer can be expressed as the ratio of itself and 1.

All of your numbers can be expressed as the ratio of integers:

Answer:

30 units ^2

Step-by-step explanation:

To find the area of the shaded region, we find find the area of the large triangle and subtract the area of the unshaded triangle.

A of large triangle = 1/2 b*h

height = (6+3) = 9

The base is found by using the pythagorean theorem c^2 = a^2 + b^2

We need to  find b^2  

c^2 -a^2 = b^2

taking the square root on each side

sqrt(c^2 -a^2) = sqrt(b^2)

                           the base = sqrt(c^2 -a^2)

                                            = sqrt( 15^2 - 9^2)

                                            = sqrt(225-81)

                                             = sqrt(144)

                                              =12

Now that we know the base and the height, we can find the area

A of large triangle = 1/2 b*h

                               = 1/2 * 12 * 9

                              = 6*9 = 54

Using the rule of similar triangles

9               6

----  =  ----------

12           base

We can use cross products to find the base of the smaller triangle

9* base = 12*6

9* base = 72

Divide by 9 on each side

base = 72/9 = 8

Now we can find the area of the smaller triangle

base = 8 and height = 6

A of smaller triangle = 1/2 b*h

                                   = 1/2 *8 * 6

                                   = 4*6 = 24

Area of the shaded region = Area large triangle - Area of small triangle

                                              = 54-24

                                                = 30

Answer:

See below for the graph.

Step-by-step explanation:

A circle or ellipse can be defined using the same sort of equation. Here, we have chosen to use the formulation ...

... ((x -a)/p)^2 +((y -b)/q)^2 -1 = 0

This will be the general form of the equation for an ellipse with center (a, b) and semi-axes p and q, in the x- and y-directions, respectively. When the axes are the same length, the ellipse is a circle.

By defining the function ...

... c(a, b, p, q, x, y) = ((x -a)/p)^2 +((y -b)/q)^2 -1

we can use the same function for all of the circles/ellipses in the figure. The parabola has vertex (0, -6) and a vertical scale factor of -1, so it can be formulated using the vertex form:

... y = k(x -a)^2 +b . . . . . for vertex (a, b) and vertical scale factor k.

3. The Right Eye (Green Circle)

Similarly for the eyes of the diagram,

The right eye = [tex](x-2)^{2}+(y-2)^{2}=1^{2}[/tex]

The left eye = [tex](x+2)^{2}+(y-2)^{2}=1^{2}[/tex]

4.  The Mouth (Purple Ellipse)

The equation of the parabola can be written as,

(x/3)² +(y+2)² -1 = 0

5. The Body (Black Parabola)

The parabola can be made using the equation,

Equation of a parabola

y = a(x-h)² + k

where,

(h, k) are the coordinates of the vertex of the parabola in form (x, y);

a defines how narrower is the parabola, and the "-" or "+" that the parabola will open up or down.

Answer:

0.48

Step-by-step explanation:

The problem at hand

[tex]500 = (2)(10^{5x})[/tex]

First divide out 2 on both side of the = sign

[tex]500 = (2)(10^{5x})[/tex]

[tex]\frac{500}{2} = \frac{(2)(10^{5x})}{2}[/tex]

[tex]250 = 10^{5x}[/tex]

Now take the base 10 log on each side of the = sign

[tex]\log_{10} (250) = \log_{10} (10^{5x})[/tex]

Now move the exponent to the left like so

[tex]\log_{10} (250) = 5x \log_{10} (10)[/tex]

Rule you need to know. [tex]\log_a (a) = 1[/tex]

[tex]\log_{10} (250) = 5x (\log_{10} (10))[/tex]

[tex]\log_{10} (250) = 5x(1)[/tex]

[tex]\log_{10} (250) = 5x[/tex]

Now divide 5 from both sides of the equation

[tex]\frac{\log_{10} (250)}{5} = \frac{5x}{5}[/tex]

[tex]\frac{\log_{10} (250)}{5} = x[/tex]

[tex]x = \frac{\log_{10} (250)}{5}[/tex]

[tex]x = 0.4795880017[/tex]

Round to nearest hundredths

[tex]x = 0.48[/tex]

Side Note:

You could approach this problem in a different manner.

For instance, we could have done the following

[tex]x = \frac{\log_{10} (250)}{5(\log_{10} (10))}[/tex]

Also, you did not have to use log with a base 10. You could have used the natural log, which is [tex]\ln_e (x)[/tex]

[tex]x = \frac{\ln_{e} (250)}{5(\ln_{e} (10))}[/tex]

Solving the equation gives 0.48 when rounded to the nearest hundredth.

To solve the equation [tex]500 = (2)(105x)[/tex] , we will first isolate the exponential term. The steps are as follows:

Divide both sides of the equation by 2 to get 250 = 105x.

Take the common logarithm (log) of both sides of the equation to get [tex]log(250) = log(105x).[/tex]

Using logarithmic properties, we have log(250) = 5x log(10)

Now we simplify further since log(10) is 1, so log(250) = 5x.

Divide both sides by 5 to solve for x, which gives [tex]x = log(250) / 5.[/tex]

Using a calculator with a LOG button, we find log(250) approximately equals 2.39794 and, therefore, x is approximately 0.47959 when rounded to five decimal places.

However, we are asked to round x to the nearest hundredth, so the final answer is x = 0.48.

Answer:

77°

Step-by-step explanation:

Angles B and C are adjacent angles of a parallelogram, so are supplementary.

... ∠C = 180° -∠B = 180° -103° = 77°

The measure of ∠BCD in a parallelogram with ∠B given as 103° is also 103° because opposite angles in a parallelogram are equal.

The measure of ∠BCD in a parallelogram can be found by using the property that opposite angles in a parallelogram are equal.

To find the measure of angle BCD, we can use the fact that angles in a quadrilateral sum up to 360 degrees.

We know that angle B is 103 degrees.

Since quadrilateral ABCD has sides AB and DC parallel, as well as sides AD and BC parallel, it is a parallelogram.

Given that ∠B is 103°, the measure of ∠BCD is also 103° because it is the angle opposite ∠B.

Answer: First prism has the greatest volume.

Step-by-step explanation:

Since we have given that

Volume of prism = Length × Breadth × Height

So, we need to find the greatest volume, for which we find volumes of all figures:

1) Volume of prism would be

[tex]5\times 7\times 5\\\\=175\ cm^3[/tex]

2) Volume of prism would be

[tex]10\times 3\times 4\\\\=120\ cm^3[/tex]

3) volume of prism would be

[tex]7\times 7\times 3\\\\=147\ cm^3[/tex]

4) Volume of prism would be

[tex]5\times 3\times 7\\\\=105\ cm^3[/tex]

Hence, first prism has the greatest volume.

The volume of the prism with the Greatest volume is 250cm³

The volume of a prism is calculated by multiplying the prism's base area by its height. Mathematically expressed as

V = Base Area×Height

, it represents the space enclosed within the prism.

Since the prism is a cuboid, then

V = l × w × h

Where h is the height , l is the length and w is the width.

V = 5 × 5 × 10

V = 250 cm³

The volume of the prism is 250cm³
