Answer:

It will take 3.6 hours to wax a car if they work together.

Step-by-step explanation:

Calvin one hour work = [tex]\frac{1}{3}[/tex]

Alvin one hour work = [tex]\frac{1}{5}[/tex]

To find out how much they can do together per hour,

We have to add [tex]\frac{1}{3}[/tex] and [tex]\frac{1}{5}[/tex]

= [tex]\frac{1}{3} + \frac{1}{5} = \frac{(5 + 3)}{15}[/tex]

= [tex]\frac{8}{15}[/tex]  --------------(1)

They can do [tex]\frac{8}{15}[/tex] of the job per hour.

If "t" is the time taken to finish the  job together, then one hour work

[tex]\frac{1}{t}[/tex] ------------------------(2)

Now we have to find the value of "t" by setting the expression (1) and (2) equal.

[tex]\frac{8}{15} = \frac{1}{t}[/tex]

It can solve by flipping the equation;

[tex]\frac{t}{1} = \frac{18}{5}[/tex]

t = 3.6 hours

It will take 3.6 hours to wax a car if they work together.

The correct answer is [tex]67\frac{9}{11}[/tex]

Write the problem in long division format,

Divide 74 by 11 to get 6,

Multiply the quotient digit (6) by the divisor 11,

Subtract 66 from 74,

Bring down the next number of the dividend,

Divide 86 by 11 to get 7,

Multiply the quotient (7) by the divisor 11,

subtract 77 from 86.

[tex]\(746 \div 11\)[/tex] equals 67 with a remainder of 9. The remainder expressed as a fraction is [tex]68\frac{2}{11}\).[/tex]

To solve the division problem 746 ÷ 11 and express the remainder as a fraction, we can perform the long division as follows:

Step 1: Divide 7 by 11, which is 0 with a remainder of 7. So, the first digit of the quotient is 0, and we bring down the next digit, which is 4, to form the dividend 74.

Step 2: Now, divide 74 by 11. The largest multiple of 11 that does not exceed 74 is 6 times 11, which is 66. The remainder is 74 - 66 = 8.

Step 3: Bring down the next digit, which is 6, to form the new dividend 86.

Step 4: Divide 86 by 11. The largest multiple of 11 that does not exceed 86 is 7 times 11, which is 77. The remainder is 86 - 77 = 9.

Step 5: Finally, bring down the last digit, which is 0, to form the new dividend 90.

Step 6: Divide 90 by 11. The largest multiple of 11 that does not exceed 90 is 8 times 11, which is 88. The remainder is 90 - 88 = 2.

Now, we have completed the long division. The quotient is 68, and the remainder is 2. To express the remainder as a fraction, we can write it as [tex]\(\frac{2}{11}\).[/tex]

So, [tex]\(746 \div 11 = 68\frac{2}{11}\).[/tex]

Step-by-step explanation:

Answer: 11.636 = 12 tickets to a whole figure

Step-by-step explanation:

Let the number of adult tickets be x and y represent children tickets.

From the question;

x + y = 28 ....... equation (i)

(7.25*x) + (y*4.50) = 158

7.25x + 4.50y = 158 ........ equation (ii)

From equation (i);

x + y = 28

y = 28 - x ...... equation (iii)

Put equation (iii) into equation (ii)

7.25x + 4.50(28 - x) = 158

7.25x + 126 - 4.50x = 158

Collect like terms and subtract

2.75x = 32

x = 11.636 approximately 12 to a round number.

Put x = 11.636 into equation (i)

11.636 + y = 28

y = 28 - 11.636

y = 16.364 approximately 16 to a whole number

Final answer:

To find the number of adult tickets purchased, we can set up two equations: C + A = 28, and 4.50C + 7.25A = 159. By solving the equations, we determine that 12 adult tickets were purchased for the carnival.

Explanation:

The question asks us to determine the number of adult tickets purchased for a carnival, given the cost of children's tickets, the cost of adult tickets, and the total amount paid for a group of tickets. Let's take the number of adult tickets as A and the number of children's tickets as C. According to the given information, the admission fee for children is $4.50 and for adults is $7.25. Also, we know that 28 tickets were purchased for a total of $159.

We can set up the following system of equations based on the information provided:

C + A = 28 (since the total number of tickets is 28)

4.50C + 7.25A = 159 (this represents the total cost of all tickets)

We can solve this system of equations using substitution or elimination method. If we rearrange the first equation to get C = 28 - A and substitute it into the second equation, we get:

4.50(28 - A) + 7.25A = 159

126 - 4.50A + 7.25A = 159

2.75A = 33

A = 33 / 2.75

A = 12

Hence, the number of adult tickets purchased is 12.

The solutions are [tex]x=15, x=-8[/tex] and [tex]x=9[/tex]

Explanation:

Part a: The equation is [tex]\frac{1}{3} (5x-9)=2(\frac{1}{3} x+6)[/tex]

Let us find the value of x.

Multiply the terms within the bracket, we get,

[tex]\frac{5}{3} x-3=\frac{2}{3} x+12[/tex]

Subtracting both sides by [tex]\frac{2}{3} x[/tex], we have,

[tex]\frac{3}{3} x-3=12[/tex]

Adding both sides by 3,

[tex]x=15[/tex]

Thus, the solution of the equation [tex]\frac{1}{3} (5x-9)=2(\frac{1}{3} x+6)[/tex] is [tex]x=15[/tex]

Part b: The equation is [tex]4(3x+5)-3=9x-7[/tex]

Multiply the terms within the bracket, we get,

[tex]12x+20-3=9x-7[/tex]

Subtracting both sides by 9x, we have,

[tex]3x+17=-7[/tex]

Subtracting both sides by 17,

[tex]3x=-24[/tex]

Dividing both sides by 3, we have,

[tex]x=-8[/tex]

Thus, the solution of the equation [tex]4(3x+5)-3=9x-7[/tex] is [tex]x=-8[/tex]

Part c: The equation is [tex]5(x+7)-3(x-4)=7x+2[/tex]

Multiply the terms within the bracket, we get,

[tex]5x+35-3x+12=7x+2[/tex]

Adding the like terms, we have,

[tex]2x+47=7x+2[/tex]

Subtracting both sides by 2 and 2x, we get,

[tex]45=5x[/tex]

Dividing both sides by 5, we have,

[tex]x=9[/tex]

Thus, the solution of the equation [tex]5(x+7)-3(x-4)=7x+2[/tex] is [tex]x=9[/tex]

Answer: 0.15J

Step-by-step explanation:

Fom th question, we obtained the following information:

F = 60N

e = 5mm

We need to covert 5mm to m

1mm = 0.001m

5mm = 5 x 0.001 = 0.005m

We need to find the spring constant (K) for the spring. This is illustrated below:

K = F / e

K = 60 / 0.005 = 12000N/m

Now we can obtain the energy stored on the spring by the doing following:

Energy = 1/2 Ke^2

Energy = 1/2 x 12000 x (0.005)^2

Answer:

Therefore side B= 11.18  and side A=2×11.18=22.36.

Step-by-step explanation:

Given,side A is twice as long as B and C is 25.

Let side B= x

Then side A = 2x

Using Pythagorean Theorem,

A²+B²=C²

⇔(2x)²+x²=25²

⇔4x²+x²=625

⇔5x²=625

⇔x²=125

⇔x=√125

⇔x =11.18

Therefore side B= 11.18  and side A=2×11.18=22.36.

Answer:

The length of side A is 22.4 and length of side B is 11.9.

Step-by-step explanation:

Given:

If side A is twice as long as B and C is 25.

Solve by using the Pythagorean Theorem.

Now, to get the lengths of side A and side B.

As side C = 25.

Let the side B be [tex]a.[/tex]

As, given A is twice as long as B.

So, the side A be [tex]2a.[/tex]

So, we solve by using Pythagorean Theorem:

A² + B² = C²

[tex](2a)^2+(a)^2=(25)^2[/tex]

[tex]4a^2+a^2=625[/tex]

[tex]5a^2=625[/tex]

Dividing both sides by 5 we get:

[tex]a^2=125[/tex]

So, using square root on both sides we get:

[tex]a=11.18.[/tex]

Rounding to the nearest tenth B =  11.9.

Now, to get A by putting the value of [tex]a[/tex]:

[tex]2a\\=2\times 11.18\\=22.36.[/tex]

Rounding to the nearest tenth A  =  22.4.

Therefore, the length of side A is 22.4 and length of side B is 11.9.

[tex]\Rightarrow \frac{1}{x - 1} = \frac{x- 2}{2x^2-2} \hspace{0.3cm} \Rightarrow \hspace{0.3cm} 2x^2 - 2 = (x-1)(x-2)[/tex]

therefore [tex]2x^2 - 2 = x^2 - 3x + 2 \hspace{0.3cm} \Rightarrow \hspace{0.3cm} x^2 + 3x - 4 = 0[/tex]

therefore [tex]x^2 + 3x - 4 = 0 \hspace{0.3cm} \Rightarrow = \hspace{0.3cm} (x-1)(x+4) = 0 \\[/tex]

Find Mean, Median, Mode, 25th Percentile, 75th Percentile, Maximum, Minimum, Range and IQR.

Let's begin by placing the data points in order from least to greatest:

32  55  66  72  72  76  77  84  88  89  89  94  97

n = 13

1) Mean sometimes called the average = the sum of the data over its number

Mean =( 32+55+66+72+72+76+77+84+88+89+89+94+97 )/13 =

         = 991/13 = 76.23 ≈ 76.2 (to the nearest tenth)

2) Median is the middle data point = 77

3) Mode is any number within a set that occurs the most often

Mode = 72 and 89

We will making a data in suitable form to find the remaining requirements:

(32  55  66  72  72  76) 77  (84  88  89  89  94  97)

4) 25th Percentile = Quartile 1 (Q1) which is the median of the first set of data

∴ 25th Percentile = (66+72)/2 = 138/2 = 69

5) 75th Percentile= Quartile 3 (Q3) which is the median of the second set of data

∴ 75th Percentile = (89+89)/2 = 89

6) Maximum = 97

7) Minimum = 32

8) Range = Maximum - Minimum = 97 - 32 = 65

9) IQR (interquartile range) = Q3 - Q1 = 89 - 69 = 20

The numerator is 57 ⇒ B

The denominator is 78 ⇒ B

The value of the fraction is 73.1% ⇒ A

Step-by-step explanation:

Let us solve it step by step

∵ The loan is 12 month

∵ The numerator is after 6 month

- Put n = 1 in each bracket

∴ The numerator = {(1 + 11) + (1 + 10) + (1 + 9) + (1 + 8) + (1 + 7) + (1 + 6)}

∴ The numerator = {12 + 11 + 10 + 9 + 8 + 7}

∴ The numerator = {57}

The numerator is 57

∵ The denominator = {(n) + (n + 1) + (n + 2) + .......... + (n + 11)}

- Do the same as the numerator put n = 1

∴ The denominator = {1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12}

∴ The denominator = {78}

The denominator is 78

Now find the value of the fraction

∵ The fraction = [tex]\frac{57}{78}[/tex]

∴ Its value = 0.730769230

- Multiply it by 100%

∴ Its value = 0.730769230 × 100% = 73.0769230%

- Round it to the nearest tenth

∴ Its value = 73.1%

The value of the fraction is 73.1%

(b) If the width is 5 inches for the scale model and the scale is still 1 inch to 2 feet, will her scale model drawing fit on a piece of paper that is 8.5 inches by 7 inches? Why or why not?​

Both the width and the length must use the same scale, thus the corresponding sides of the scale model and the drawing must be proportional.

In the model the ratio of the length to the width is 3 inch / 5 inch

In the paper the ratio of the length to the width is 8.5 inch / 7 inch

Hence, you can see that in the model the length (mumerator of the fraction) is less than the width (denominator) while in the paper it is the opposite. Bieng the two ratios different, they are not proportional, and you conclude that her scale model drawing will not fit on a piece of paper that is 8.5 inches by 7 inches.

Answer: Zero slope

Step-by-step explanation: A common mistake made by many students is to confuse what no slope is and what zero slope.

If a line has a slope of zero, it means that the line is flat or horizontal.

No slope is a vertical line or straight up and down. No slope means that we cannot describe its slope using a number because its line is vertical and it's slope is undefined. This has to do with dividing a number by 0. When you do this, you should get an error message or it should say undefined.

So, this line would have zero slope because it's flat.

Final answer:

The correct TVM Solver setup for Troy's loan has a monthly interest rate of 0.8% and the rest of the parameters reflect the details of the loan and payment structure, making Option B the right choice.

Explanation:

To calculate the number of monthly payments Troy will have to make to pay off the loan for the television, we can use the Time Value of Money (TVM) formula where certain values will be plugged into the TVM Solver of a graphing calculator. Given the loan amount ($1850) and APR (9.6% annually, compounded monthly), we have to adjust the annual percentage rate to a monthly rate by dividing it by 12 months, resulting in a 0.8% monthly interest rate. Therefore, the values entered should reflect a monthly rate, not an annual rate.

The correct setup for the TVM Solver would be:

Therefore, the correct answer is Option B, where the monthly interest rate is accurately represented.

Answer:

The commission rate is 9%

Step-by-step explanation:

We are given;

We are required to determine the commission rate;

We need to know that;

Total earnings = Monthly salary + Commission

Therefore;

Commission = Total earnings - monthly salary

                     = $1182.60 - $315

                     = $867.6

Therefore, assuming the commission rat is x %

Then;

x/100 × $9640 = $867.6

x/100 = $867.6 ÷ $9640

x/100 = 0.09

 x = 9%

Therefore, the commission rate is 9%
