Which of the following is a correct interpretation of the expression 6-13?

Answer:

4.5%

Step-by-step explanation:

Find interest rate by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.

I = $720, P = $2000 and t = 8 years, so

I = P*i*t

i = I/P*t

i = 720 / 2000 * 8

i = 0.045 = 4.5% per year

The interest rate, calculated with the simple interest formula, for an investment of $2000 that grows to $2720 over 8 years is 4.5%.

The subject is about determining the interest rate for an investment in a simple interest account. The formula for calculating simple interest is: Interest = Principal x Rate x Time (I = PRT). In this case, the principal (P) is $2000, the time (T) is 8 years, and the interest (I) earned is the difference between the final balance and the initial deposit, which is $2720 - $2000 = $720.

To find the rate (R), we rearrange the formula to: R = I / (P x T). Plugging in the numbers, we get: R = $720 / ($2000 x 8) = 0.045, or 4.5% when expressed as a percentage.

The width of the rectangle is 5.55 ft and the length is 19.425 ft. The perimeter of the rectangle is 25.95 ft and the area is 107.95875 sq ft.

To find the width of the rectangle, we can set up the equation

5/2 = 13.875 / width

Solving for width gives us width = 5.55 ft. Therefore, the length of the rectangle is 13.875 + 5.55 = 19.425 ft.

The perimeter of a rectangle is given by the formula 2(length + width). Substituting the given values, we get the perimeter to be 2(19.425 + 5.55) = 25.95 ft.

The area of the rectangle is given by the formula length * width. Substituting the given values, we get the area to be 19.425 * 5.55 = 107.95875 square feet.

Answer:

Toner = $45.00; ink = $25.50

Step-by-step explanation:

Let T = the cost of a toner cartridge and I = the cost of an ink cartridge

We have two conditions:

(1)                      T = I + 19.50

(2)           4T + 11I = 460.50     Substitute (1) into (2)

4(I + 19.50) + 11I = 460.50     Remove parentheses

 4I + 78.00 + 11I = 460.50     Combine like terms

      15 I + 78.00 = 460.50     Subtract 78.00 from each side

                    15I = 382.50      Divide each side by 15

(3)                  I = 25.50

=====

Substitute (3) into (1)

T = 25.50 + 19.50

T = 45.00

=====

Check:

(1)                         45.00 = 25.50 + 19.50

                           45.00 = 45.00

(2) 4×45.00 + 11×25.50 = 460.50

         180.00 + 280.50 = 460.50

                        460.50 = 460.50

Answer:

D. log (x-2)

Step-by-step explanation:

We can see that in the graph of the function g(x), the graph is shifted toward the right.

We know that, to shift a graph to the right, we subtract that number of units inside the function.

For example if we are plotting a graph of F(x) and if we have to shift the function to the right by 2 units, we can write it as, [tex]F(x-2)[/tex].

Similarly, here the graph of log (x) is shifted 2 units to the right so we can write the function as,

[tex]log (x-2)[/tex] (we subtract inside the function).

Answer:

D. [tex]log(x-2)[/tex]

Step-by-step explanation:

We have been given function's [tex]f(x)=log(x)[/tex] graph and graph of function g(x). We are asked to choose the correct function formula for g(x).

We can see that our parent function f(x) is translated to right to get function g(x).  

The rule for translating a function to right by k units is:      

[tex]f(x)\rightarrow f(x-k)[/tex]

We can see that our parent function is shifted 2 units to right as our parent function crosses x-axis at x equals 1, while our new function crosses x-axis at x equals 3. So our new function g(x) will be:

[tex]g(x)=log(x-2)[/tex]

Therefore, the expression [tex]log(x-2)[/tex] is equal to g(x) and option D is the correct choice.

Answer:

To save 6 months' worth in a fund would be $2858.59.

Step-by-step explanation:

At a wage of $13.70 per hour for a 40 hour work week, your gross pay (not including any taxes or deductions) is $548 per week, or $2192 per month.  Deductions and taxes are 7.65% + 11.55% + 8.35%, for a total of 27.55% that comes out of your gross pay.  $2192 multiplied by 27.55%, or .2755, is $603.90, therefore, in order to find your realized income per month, you must subtract your gross pay by the amount of deductions and tax withholdings:  $2192 - $603.90 = 1588.10.  Another 30% of your realized income is for housing and fixed expenses, or $1588.10 multiplied by 30%, or 0.30, which comes to $476.43.  If you want to save 6 months' of expenses in an emergency fund, simply take your monthly expenses, $476.43, and multiply by 6 = $2,858.59.  

The correct answer is option d. $2,858.59

1. Monthly gross income should be calculated using the exact number of days in the month, which can vary. However, since we are given 4 weeks per month, we will continue with that assumption.

2. The tax rates are percentages, so we need to convert them to decimals for calculation:

Total tax rate = 0.0765 + 0.1155 + 0.0835 = 0.2755.

3. The realized income after taxes should be calculated as follows:

Realized income after taxes = [tex]\$2,192 \times (1 - 0.2755) = \$2,192 \times 0.7245 = \$1,588.53.[/tex]

4. The monthly housing and fixed expenses are correct at $476.56.

5. The emergency fund calculation is also correct:

Emergency fund = [tex]6 \times \$476.56 = \$2,859.36.[/tex]

Upon re-evaluation, the correct calculation for the emergency fund is $2,859.36, which should be rounded down to $2,858. However, the options provided suggest that the correct answer is $3,277.17. This indicates that there may be an error in the provided options or in the interpretation of the question.

Given the calculations above, none of the provided options match the calculated emergency fund. The closest option is d) $2,858.59.

Note that this multiplication problem has two (2) multiplicands; that is, two (2) numbers being multiplied by each other;  which are:  "56" and "213"

The "product" refers to the number obtained when multiplicands in a multiplication problem are multiplied together.

In this case, the product given is:  " 103 " ; which is smaller than one of the "multiplicands" in the problem — specifically, "213" !

This does not make sense; and this along tells us that the answer — "213" ; is incorrect.

________________________________________________

Furthermore, if we multiply the two (2) given multiplicands:

Box-3: [tex]\frac{1\thinspace stud}{15\thinspace in}[/tex]

Box-4: 42 studs

Explanation:

Given:

Wall is 17.5 yds long.

In 1 yard, there are 3 feet.

Therefore,

[tex]\frac{17.5\thinspace yd}{1} * \frac{3\thinspace ft}{1\thinspace yd}[/tex]

In Box-1, you should put [tex]\frac{3\thinspace ft}{1\thinspace yd}[/tex].

In 1 foot, there are 12 inches.

Therefore,

[tex]\frac{17.5\thinspace yd}{1} * \frac{3\thinspace ft}{1\thinspace yd}*\frac{12\thinspace in}{1\thinspace ft}[/tex]

In Box-2, you should put [tex]\frac{12\thinspace \thinspace in}{1\thinspace ft}[/tex].

He needs to place 1 stud every 15 inches.

Therefore,

[tex]\frac{17.5\thinspace yd}{1} * \frac{3\thinspace ft}{1\thinspace yd}*\frac{12\thinspace in}{1\thinspace ft}*\frac{1\thinspace stud}{15\thinspace in}[/tex]

In Box-3, you should put [tex]\frac{1\thinspace stud}{15\thinspace in}[/tex].

Now multiple all the numbers, you will get the number of studs.

[tex]\frac{17.5\thinspace yd}{1} * \frac{3\thinspace ft}{1\thinspace yd}*\frac{12\thinspace in}{1\thinspace ft}*\frac{1\thinspace stud}{15\thinspace in} = 42\thinspace studs[/tex]

In Box-4, write 42 studs.

-i

To calculate the number of additional studs needed, convert the length of the wall to inches and divide by the interval between each stud. Subtract 1 from the total number of intervals to find the number of additional studs needed.

To determine the number of additional studs needed, we need to calculate the number of intervals between studs. First, we need to convert the length of the wall to inches, which is 17.5 yds * 3 ft/yd * 12 in/ft = 630 inches. Next, we divide the length of the wall by the interval between each stud, 630 inches / 15 inches = 42 intervals. Since the first stud has already been placed, we subtract 1 from the total number of intervals to find the number of additional studs needed: 42 - 1 = 41 additional studs.

Answer:

A) X = -5,  Y = 1

B) X = -2, Y = 4

C) X = -5 , Y = 4  

Step-by-step explanation:

The reflection over an x-axis means the values associated with the x remains same while y-axis variable change their sign.  

The three co-ordinates of this figure are  

A) X = -5,  Y = -1

B) X = -2, Y = -4

C) X = -5 , Y = -4  

Now going by the above rule to determine the co-ordinates when the image is reflected over x-axis, the new co-ordinates are:

A) X = -5,  Y = 1

B) X = -2, Y = 4

C) X = -5 , Y = 4  

Step-by-step explanation:

Please find the attachment.  

We have been given an image on coordinate plane and we are asked to reflect our given image over the x-axis.

The rule for reflection for an image over x axis is: [tex](x,y)\rightarrow(x,-y)[/tex]. This means that after reflection about x axis, x coordinates remain same but y-coordinates are transformed into their opposite sign.

Let us give names to vertices of our pre-image. A(-5,-1), B(-5,-4) and C(-2,-4).

When we will reflect our pre-image (ABC) about x-axis, x coordinates will remain same, so x coordinates will remain negative.

Since y-coordinates will change into their opposite sign, so coordinates of y will be positive for our image as y-coordinates of pre-image are negative.

A                    A'

(-5,-1)            (-5,1)

B                    B'

(-5,-4)           (-5,4)

C                    C'

(-2,-4)            (-2,4)  

Therefore, coordinates of our image A'B'C' will be: A'(-5,1), B'(-5,4) and C'(-2,4).

To multiply it , first we multiply the numbers.

46.2  times 5.7 is 263.34

Now we multiply the exponents. To multiply exponents we apply exponential property.

[tex]a^m \cdot a^n= a^{m+n}[/tex]

When the exponents with same base are in multiplication then we add the exponents

[tex]10^{-1} \cdot 10^{-6}=10^{-7}[/tex]

[tex](46.2 \cdot 10^{-1})(5.7 \cdot 10^{-6})[/tex]

[tex]263.34 \cdot 10^{-7}[/tex]

Answer:

60 child tickets were sold

Step-by-step explanation:

Let no of children tickets sold that day be c and adult tickets be a

Then since total number of tickets sold is 148, we have

c+a = 148  ... i

Also given that admission fee is 6.00 for children and 9.70 for adults

So for c children tickets sold value= 6c and for adults it is 9.7a

total revenue = 6c+9.7a=1213.60 ... ii

We got two equations in two variables c and a

Let us solve this

a =148-c. substitute this in ii

6c+9.7(148-c) = 1213.60

Simplify the above to have

222 = 3.7c

Or c = 60

No of child tickets sold = 60

Answer:

The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept.  It represents the initial cost to join the gym.

Step-by-step explanation:

C(m)= 50m + 79.50,

This is written in the form y= mx+b where m is the slope and b is the y intercept.

The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept.  It represents the initial cost to join the gym.

The slope of the function represents the cost of each additional month of membership, while the y-intercept represents the initial cost of joining the gym.

The slope of the function C(m) = 50m + 79.50 represents the cost of each additional month of gym membership. In this case, the slope is 50, meaning that for every additional month of membership, the cost increases by $50.

The y-intercept of the function, which is 79.50, represents the initial cost of joining the gym. This can be considered as the one-time fee or the cost for 0 months of membership.
