Answer:

Weekly income = $518

Monthly income = $2072

Rent = $621.6

Step-by-step explanation:

$14 per hour

37 hours per week

37 × 14 = $518

There is about 4 weeks in a month.

$518 × 4 = $2,072

30% of $2,072 = $621.6

Step-by-step explanation:

Kim's weekly income can be found by multiplying her hourly wage to the number of hours she works per week.

So, we have $14 * 37 = $518 weekly income.

Let's assume that Kim gets paid bi-weekly like most jobs, so she'll get paid twice a month usually, ignoring all holidays and other exceptions.

So, we have her weekly income and we are assuming she gets paid bi-weekly per month. So, we need to make her weekly income into a bi-weekly income. We just double her weekly income.

$518 * 2 = $1036 bi-weekly.

Now, we know are assuming she gets paid twice a month, so we need to double her income one more time.

$1036 * 2 = $2072 monthly income.

Now, we have her monthly income, but she can only pay 30% of it towards rent. So, we got to find out what is 30% of $2072.

There are a couple of ways to do this, but the most efficient way is to multiply $2072 by .3

So, $2072 * .3 = $621.60

She can only have $621.60 go towards rent. Hope this helps!

Answer:

y=(-3/4)x+3/2

Step-by-step explanation:

3x+4y-6=0

3x+4y=6

4y=6-3x

4y=-3x+6

y=(-3/4)x+3/2

To convert 3x + 4y - 6 = 0 to y = mx + b form is :[tex]y = -\frac{3}{4}x + 1.5.[/tex]

The equation given is 3x + 4y - 6 = 0. To write it in y = mx + b form, follow these steps:

Now, the equation is in slope-intercept form where m (the slope) is[tex]-\frac{3}{4}[/tex] and b (the y-intercept) is 1.5.

Answer:

(1,0)

Step-by-step explanation:

The given functions are:

f(x) = log₂x

and

g(x) = log₁₀x

We know that logarithm of 1 is always zero.

This means that irrespective of the base, the y-values of both functions will be equal to 0 at x=1

Therefore the point the graphs of f and g have in common is (1,0)

Answer:

(0, 6) and (1, 2)

Step-by-step explanation:

hello :

(0, 6) and (1, 2)

put x =0 and y =6 in this system : y=x²−5x+6

y=−4x+6

you have : 6 = 0²-5(0)+6 =6  ...right

                  6 =-4(0)+6 .... right

same mhethod for:(1, 2)

The solutions are B) (0, 6) and (1, 2).

To find the solutions to the given system of equations:

y = x² − 5x + 6 and y = −4x + 6, we need to set the equations equal to each other and solve for x:

Set x² − 5x + 6 equal to −4x + 6:

x² − 5x + 6 = −4x + 6

Rearrange the equation to get:

x² − x = 0

Factor the equation:

x(x − 1) = 0

Solve for x:

x = 0 or x = 1

Substitute these values back into either original equation to find y:

When x = 0: y = −4(0) + 6 = 6 (so one solution is (0, 6)).

When x = 1: y = −4(1) + 6 = 2 (so another solution is (1, 2)).

Therefore, the solutions to the system of equations are B) (0, 6) and (1, 2)

Answer:

PC=40 units

Step-by-step explanation:

we know that

The circumcenter is the center of the triangle's circumcircle (the circle that passes through all three of the triangle's vertices)

That means

PC=RC=QC----> is the radius of the circumcircle

step 1

Find the value of x

equate PC and RC

[tex]3x+7=5x-15[/tex]

solve for x

[tex]5x-3x=7+15\\2x=22\\x=11[/tex]

Verify

substitute the value of x

[tex]PC=3x+7=3(11)+7=40\ units[/tex]

[tex]RC=5x-15=5(11)-15=40\ units[/tex]

[tex]QC=51-x=51-11=40\ units[/tex]

so

[tex]PC=RC=QC[/tex] ----> is ok

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]

Answer:

Therefore x = 1 is an extraneous solution.

Step-by-step explanation:

The solution to the equation StartFraction 1 Over x minus 1 EndFraction = StartFraction x minus 2 Over 2 x squared minus 2 EndFraction

[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]

therefore x = 1 and x = -4 but we can see that if we place x = 1 in the original solution then [tex]\frac{1}{x-1} = \frac{1}{1-1} = \frac{1}{0}[/tex] which is indeterminate.

Final answer:

To calculate the amount of chemical in the pond after a very long time, multiply the rate at which the chemical flows in per hour by the number of hours that have passed.

Explanation:

To find out how much of the chemical will be in the pond after a very long time, we can first calculate the amount of chemical that flows into the pond per hour. Since 0.01 g of chemical flows in per gallon, and the rate of flow is 300 gallons per hour, the amount of chemical added per hour is 0.01 g/gal * 300 gal/hr = 3 g/hr.

Since the amount of water in the pond remains constant, the concentration of the chemical will also remain constant. Therefore, after a very long time, the amount of chemical in the pond will be the amount added per hour multiplied by the number of hours that have passed. So, if time is represented by 't', then the amount of chemical in the pond after a very long time is given by 3 g/hr * t.

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

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%

Step-by-step explanation:

the line has a value which is y=7

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.

No Alan did not break even

Alan incured a loss of 6.25 %

Solution:

Given that,

Alan bought two bikes

He sold one to Beth for $300 taking a 25% loss

He also sold one to Greta for $300 making a 25% profit

When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss

Which is given as:

[tex]loss\ \% = (\frac{x}{10})^2[/tex]

Here, x = 25

[tex]loss\ \% = (\frac{25}{10})^2\\\\loss\ \% = 2.5^2\\\\loss\ \% = 6.25[/tex]

Thus the loss percentage is 6.25 %

Answer:

0.027, [tex]\frac{1}{6}[/tex], 23%, 0.29, [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Here we have to convert the fractions and percents to decimal form, then we have to arrange them from smallest to largest.

[tex]\frac{1}{6} = 0.167[/tex]

23% = [tex]\frac{23}{100} = 0.23[/tex]

[tex]\frac{3}{5} = 0.6[/tex]

0.29

0.027

Now we have to arrange from smallest to largest.

0.027 < 0.167 < 0.23 < 0.29<0.6

From smallest to largest

0.027, [tex]\frac{1}{6}[/tex], 23%, 0.29,[tex]\frac{3}{5}[/tex]

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%
