Answer:

a) 3x-5=16

b) 30cm

Step-by-step explanation:

a) 5(x-1)=2(x+8)

   5x-5=2x+16

   5x-2x-5=16

      3x-5=16

b) solving the equation gives x=7

put x=7 into first line, 5(7-1)=30cm

to check we can place it into second one as well

2(7+8)=30cm

Answer:

Since slopes of both lines are not negative reciprocals. Therefore Lines are not perpendicular to each other

Step-by-step explanation:

Slope of -7x-2y=-8 is -7/2

Slope of 2x+7y=-3 is -2/7

For perpendicular lines slopes are negative reciprocals of each other

Answer:

The answers are that x = 8 and y = 7%

Step-by-step explanation:

To find the value of x, we need to divide 1.36 by the percentage it is of the whole (17%).

1.36/17% = 8

And now to find y, we divide 1.05 by 15

1.05/15 = 7%

Answer:

TRUE

Step-by-step explanation:

Standard deviation is defined as the measure of spread. In other words, it shows and determines how spread out the numbers are, i.e. the amount of dispersion or variation of a given set of numbers.

The standard deviation ranges from zero to any number. So it is possible to have a standard deviation of number 445,000 because the standard deviation can be of any value greater than or equal to zero.

Using the standard deviation concept, it is found that since the standard deviation is always a positive value or zero, the statement is true.

Hence, considering that  the standard deviation is always a positive value or zero, the statement is true.

Answer:

1. $2906.25

2. $406.25

Step-by-step explanation:

2500+ (3.25% of 2500) (5)

2500+ (81.25) (5)

2500+ $406.25

=2906.25

3.25% of 2500

=406.25

The required solution,
(a) Amount in the account after 5 months will be $2,933.53.
(b) Compound interest =  $433.53.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Amount = principal[1 + r/n]ⁿᵃ

Principal = P rate= r Time =a  , n = compounding frequency

Amount = 500[1 + 0.0325/12]⁵
Amount = $2,933.53

Compound interest = Amount - principal
                             = 2933.53 - 2500
                             = $433.53

Thus, the required solution,
(a) Amount in the account after 5 months will be $2,933.53.
(b) Compound interest =  $433.53.

You haven't listed the information in the table, but that's okay :). I believe I can still help you.

To find the average score on the test for this group you would have to add up all the test scores listed in the chart, then divide that sum by the number of people in the group.

Here's an example;

I'll make a list of people with some test scores

Jimmy- 80

Andrea- 44

Samuel- 15

Jerica- 65

To find the average of their scores, I'll first add up their points:

80+44+15+65 = 204

Once I've calculated my sum, I will divided that sum by the number of people who took the test. In this case it's 4 different people, so :

204÷4= 51

So in my made up scenario the average score in my group was 51.

Now you can apply this process into your problem.

(Hope this helps :). Please let me know if you need more help on this problem)

Calculate the sale price you will pay for an item based on the type of discount in the sale promotion:

Percent off list price

Fraction off list price

Multi-item discount

You can also compare discounts to find the lowest price for an item. Enter a percentage off price, fraction off price, multiple items for the price of one or other "two-for" type discounts. Compare the final discounted price for each in the answer table.

Sale Price Formulas and Calculations

Percent Off Price Formula

Discounted price = List price - (List price x (percentage / 100))

Example: Sale price is 25% off list price of $130

Convert 25% to a decimal by dividing by 100: 25/100 = 0.25

Multiply list price by decimal percent: 130*0.25 = 32.50

Subtract discount amount from list price: 130 - 32.50 = 97.50

With the formula:

130 - (130*(25/100)) =

130 - (130*0.25) =

130 - 32.50 = 97.50

25% off $130 is $97.50

Answer:

103.96

Step-by-step explanation:

100% (full price)                                                             --> 129.95

80% (retail price = 100%(full price) - 20% (discount)) --> x

x = 80*129.95/100 = 103.96

Step-by-step explanation:

4(5x+2)=14x+32

20x+8 = 14x+32

20x-14x+8=14x-14x +32 (Both side +14x)

6x+8=32 (cancel 14x -14x)

6x+8-8=32 -8(both side -8)

6x=24 (both side divide 6)

6x/6=24/6

Answer:

The diameter of each coin is approximately 2.778 centimeters.

Step-by-step explanation:

According to the statement, 0.12 cubic meters ([tex]1.20\times 10^{8}\,mm^{3}[/tex]) were used to produce 99000 coins. First, we calculate the volume of each coin ([tex]V_{c}[/tex]), measured in cubic meters, by dividing the total volume by the number of coins. That is:

[tex]V_{c} = \frac{1.20\times 10^{8}\,mm^{3}}{99000}[/tex]

[tex]V_{c} =1212.121\,mm^{3}[/tex]

Then, diameter ([tex]D[/tex]), measured in milimeters, can be derived from the following volume formula:

[tex]V_{c} = \frac{\pi}{4}\cdot D^{2}\cdot h[/tex] (1)

Where [tex]h[/tex] is the thickness of the coin, measured in milimeters.

If we know that [tex]h = 2\,mm[/tex] and [tex]V_{c} =1212.121\,mm^{3}[/tex], then the diameter of each coin is:

[tex]D^{2} = \frac{4\cdot V_{c}}{\pi\cdot h}[/tex]

[tex]D = 2\cdot \sqrt{\frac{V_{c}}{\pi\cdot h} }[/tex]

[tex]D = 2\cdot\sqrt{\frac{1212.121\,mm^{3}}{\pi\cdot (2\,mm)} }[/tex]

[tex]D \approx 27.779\,mm[/tex]

The diameter of each coin is approximately 2.778 centimeters.

Answer:

Volume)

125 inches cubed

Surface area)

150 inches squared

Step-by-step explanation:

So pretty simple and straight forward, nothing hard

So first we know the side length is 5

The volume of a cube formula is s^3

So 5^3=125

Thats one

The second one is 6s^2

So plug it in

6*5^2

Follow orders of operations

5^2=25

25*6=150

So 150 inches squared

Answer:

1/26 meter

Step-by-step explanation:

You would start by dividing 1/4 by 6. You'd have to multiply 1/4 by the reciprocal of 6 (the reciprocal of 6 would be 1/6). Then you get (1/4) * (1/6), which is equal to 1/24.

Carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.

Let the length of each piece = x meters

Since, the number of pieces (of equal length) of the wooden board = 6

Therefore, total length of wooden board = 6x

It's given in the question that the length of the wooden board is [tex]\frac{1}{4}[/tex] meter.

Therefore, 6x = [tex]\frac{1}{4}[/tex]

[tex]\frac{6x}{6}=\frac{1}{4\times 6}[/tex]

[tex]x=\frac{1}{24}[/tex] meter

    Hence, carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.

Step-by-step explanation:

Given that:

Cost to rent one game at store S = $2.50

Monthly fee = $5.00

Let,

v be the number of video games.

Total cost = 2.50v + 5

Cost to rent one game at store T = $5.00

y = 5v
