goes through (0,0) and is parallel to the y=-5
Answers
Answer:
y=0
Step-by-step explanation:
Parallel lines never intersect therefore you need to find what y=-5 would look like on a graph (look at the image for reference, it is the blue line). Because it is a straight line then you just need to find what would make a straight line across the origin, therefore you would have to do y=0 (the red line on the image.)
The reason for putting y=0 or y=-5 is because the y value will ALWAYS stay the same and the x value will continue going on and on, without intersecting.

Answers
Answer:
Part 5) Option b [tex]2x\sqrt{3}\ ft[/tex]
Part 6) Option d. [tex]4y\sqrt[3]{2}\ mm[/tex]
Step-by-step explanation:
Part 5) we know that
The area of a square is equal to
[tex]A=b^2[/tex]
where
b is the length side of the square
we have
[tex]A=12x^2\ ft^2[/tex]
substitute
[tex]12x^2=b^2[/tex]
Solve for b
take square root both sides
[tex]b=\sqrt{12x^{2}}[/tex]
Remember that
[tex]12=(2^2)(3)[/tex]
substitute
[tex]b=\sqrt{(2^2)(3)x^{2}}[/tex]
Applying property of exponents
[tex]b=\sqrt{(2^2)(3)x^{2}}=[(2^2)(3)x^{2}]^{\frac{1}{2}}=[2^2x^2]^{\frac{1}{2}}3^{\frac{1}{2}}=2x\sqrt{3}\ ft[/tex]
Part 6) we know that
The volume of a cube is equal to
[tex]V=b^3[/tex]
where
b is the length side of the cube
we have
[tex]V=128y^3\ mm^3[/tex]
substitute
[tex]128y^3=b^3[/tex]
Solve for b
take cubic root both sides
[tex]b=\sqrt[3]{128y^3}[/tex]
Remember that
[tex]128=(2^7)=(2^6)(2)=(2^2)^3(2)[/tex]
substitute
[tex]b=\sqrt[3]{(2^2)^3(2)y^3}[/tex]
Applying property of exponents
[tex]b=\sqrt[3]{(2^2)^3(2)y^3}=[(2^2)^3(2)y^3]^{\frac{1}{3}}=[(2^2)^3y^3]^{\frac{1}{3}}2^{\frac{1}{3}}=2^2y\sqrt[3]{2}=4y\sqrt[3]{2}\ mm[/tex]

A data set has nine values. The mean of the set is 5. When a tenth value is added, the mean becomes 6. What is the tenth value?
Answers
The tenth value is 15
Solution:
Given that, data set has 9 values
The mean of the set is 5
Number of values = 9 and mean = 5
The mean is given by formula:
[tex]mean = \frac{\text{Sum of terms}}{\text{Number of terms}}[/tex]
[tex]5 = \frac{\text{Sum of 9 terms}}{9}\\\\sum\ of\ 9\ terms = 5 \times 9 = 45[/tex]
When a tenth value is added, the mean becomes 6
Let the tenth value be "x"
New mean is given as:
[tex]6 = \frac{\text{sum of 9 terms} + x}{10}\\\\sum\ of\ 9\ terms + x = 60[/tex]
The tenth value is given as:
sum of 9 terms + x = 60
45 + x = 60
x = 60 - 45
x = 15
Thus the tenth value is 15

A 12 ounce can of Coke costs $1.00 when purchased from the soda machine at the school. An 16 oz bottle of Pepsi from the soda machine at the local gas station costs 1.35. Is the can of coke or bottle of Pepsi the best buy?
Answers
Answer:
Can of Coke
Step-by-step explanation:
Calculate how much money each ounce of drink costs, or the money per ounce ($/oz).
Coke:
$/oz = $1 ÷ 12oz = $0.083333/oz
Pepsi:
$/oz = $1.35 ÷ 16oz = $0.084375/oz
Coke < Pepsi
0.083333 < 0.084375
The calculations show that you would pay more money for one ounce of Pepsi than for one ounce of Coke. Coke costs less than Pepsi.
Therefore the can of Coke is the best buy.
Final answer:
After calculating the cost per ounce for both the Coke and Pepsi, the 12 ounce can of Coke at $1.00 is the better buy as it costs approximately $0.0833 per ounce compared to the 16 ounce bottle of Pepsi at $1.35, which costs approximately $0.0844 per ounce.
Explanation:
To determine whether the can of Coke or the bottle of Pepsi is the better buy, we will calculate the cost per ounce for each.
For the 12 ounce can of Coke priced at $1.00, the cost per ounce is calculated as follows:
Divide the total cost by the number of ounces: $1.00 \/ 12 ounces.
This results in approximately $0.0833 per ounce for the Coke.
For the 16 ounce bottle of Pepsi priced at $1.35, the cost per ounce is calculated in a similar manner:
Divide the total cost by the number of ounces: $1.35 \/ 16 ounces.
You get approximately $0.0844 per ounce for the Pepsi.
Comparing the two, the cost per ounce of Coke is cheaper than the cost per ounce of Pepsi. Thus, the can of Coke is the best buy.

At soccer practice, for every 5 minutes that Bob runs, e spends 20 minutes practicing dribbling. If Bob keeps the same ratio and he spends 36 minutes practicing dribbling, how many minutes does he spend running?
Answers
5/20=x/36
1/4=x/36
x=9
9 minutes.
Final answer:
To determine the time Bob spends running, a proportion is set up based on the original 5:20 running to dribbling ratio. Solving this proportion shows that Bob runs for 9 minutes when he spends 36 minutes dribbling.
Explanation:
Bob's practice ratio for running and dribbling is 5 minutes running to 20 minutes dribbling. To find how many minutes Bob spends running when he practices dribbling for 36 minutes, we set up a proportion using the original ratio. The proportion is:
5 minutes running / 20 minutes dribbling = x minutes running / 36 minutes dribbling
To solve for x, we cross-multiply:
(5 minutes running) × (36 minutes dribbling) = (x minutes running) × (20 minutes dribbling)
This gives us:
180 = 20x
Now divide both sides by 20 to solve for x:
x = 180 / 20
x = 9 minutes
Thus, Bob spends 9 minutes running when he practices dribbling for 36 minutes.

what is 58% of 18 Show and explain your work, please!!!
Answers
Answer:
10.44
Step-by-step explanation:
okay so percentages can be converted to decimals
to do this, you can either:
move the decimal space to the left twice
or
divide the percentage (in this case 58) by 100,
regardless you will get the same answer
58.0 → 5.80 → 0.58
now that you have 58% as a decimal, all you have to do is multiply it by 18
(0.58)(18) = 10.44
therefore, 58% of 18 is 10.44
Final answer:
To calculate 58% of 18, convert the percentage to a decimal (0.58) and multiply it by 18, resulting in 10.44.
Explanation:
To find what 58% of 18 is, we use the concept that 'percent' means 'per hundred' or 'out of 100'. So essentially, we need to find 58 out of every 100 parts of 18. This calculation can be represented by the mathematical expression 0.58 x 18 (since 58% as a decimal is 0.58). The steps to solve this are:
Convert the percentage to a decimal: 58% = 0.58.Multiply the decimal by the total number: 0.58 x 18.Perform the multiplication: 0.58 x 18 = 10.44.So, 58% of 18 is 10.44.

than the mean score.
130
150
The mean score would decrease more

median: 125
There would be no effect on either the
mean score or the median score.
Answers
Answer:the mean score would decrease more than the median score
Step-by-step explanation:
i did the quiz
Adding a score of 0 would decrease the mean more than the median, with the new mean being 100 and the new median 120.
Adding a score of 0 to the data set of game scores will impact both the mean and the median of the distribution. However, the way each measure of central tendency is affected will be different.
For the mean, which is the arithmetic average, adding a score of 0 will bring the average down. To find the new mean, you would add 0 to the sum of the existing scores and divide by the new total number of scores. Since 0 is lower than any of the existing scores (100, 120, 130, and 150), the mean will decrease.
The initial mean is 125, which is the sum of all the scores (500) divided by the number of scores (4).
Calculating the new mean after including the score of 0, we get (500 + 0) / (4 + 1) = 500 / 5 = 100. This shows the mean would decrease as a result of the 0 score.
As for the median, if we incorporate the score of 0 into the data set, it will become the new lowest score. With an odd number of scores (5), the median will be the middle value.
The scores in order would be 0, 100, 120, 130, and 150. So the new median would be 120. The median is less influenced by extreme values, especially when they are an outlier like the 0 in this case.
Therefore, the correct answer is that the mean score would decrease more than the median score when adding a 0 to the data set.

What does x equal 2(x-3)=14
Answers
Answer: x = 10
Explanation: To solve this equation for x, we start by distributing the 2 through the parentheses on the left side.
So we have 2 times x which is 2x and 2 times -3 which is -6. So our equation now reads 2x - 6 = 14.
Solving from here,
we add 6 to both sides of the equation and we have 2x = 20 and dividing both sides by 2, we find that x = 10.
We can check our answer by substituting a 10 back in for x in the original equation and we have 2(10 - 3) = 14.
10 - 3 is 7 so we have 2(7) = 14 or 14 = 14 which is a true statement so our answer checks.

Final answer:
The area of the rectangle garden as a function of its width w is [tex]A(w) = 2w^2[/tex], where the length is twice the width of the garden.
Explanation:
The landscaper wishes to make a rectangle flower garden where the length is twice the width. If we denote the width as w and the length as 2w, we can express the area A as a function of its width.
The formula for the area of a rectangle is length × width, so the area function A(w) would be:
A(w) = length × width
= 2w × w
= [tex]2w^2[/tex]
So, the area of the garden as a function of its width is [tex]A(w) = 2w^2.[/tex]
Luis choosing one card from the deck then choosing a second card without replacing the first. Is this independent or dependent
Answers
Luis choosing one card from the deck then choosing a second card without replacing the first is a dependent event.
Step-by-step explanation:
Lets define independent and dependent events first.
Independent events:
The events are said to be independent if the probability of occurrence of one event doesn't affect the probability of second event.
Dependent events:
The events in which the probability of occurrence of one event affects the second event's probability of occurrence, are called dependent events.
Now,
When a card is drawn from a deck of cards and NOT replaced, it makes the second event's probability depend on first event as the sample space for second event changes due to the first event.
Hence,
Luis choosing one card from the deck then choosing a second card without replacing the first is a dependent event.
