Suppose that 21 inches of wire costs 63 cents. At the same rate, how much (in cents) will 14 inches of wire costs?

Final answer:

To convert gallons to liters, use the conversion factor of 1 gallon being equal to 3.8 liters to find that there are approximately 120.1 liters of oil in the barrel.

Explanation:

To convert gallons to liters, we need to use the conversion factor of 1 gallon being equal to 3.8 liters.

Calculate the total liters in the barrel: 31.6 gallons * 3.8 liters/gallon = 120.08 liters

Therefore, there are approximately 120.1 liters of oil in the barrel.

Answer:

Option A

Step-by-step explanation:

It is given that Marta sold [tex]$ x $[/tex] oranges on Thursday.

She has sold twice as many as on Friday. Therefore, she must have sold [tex]$ 2x$[/tex] oranges on Friday.

And the total amounts to 108.

That is, [tex]$ x + 2x = 108 $[/tex]

Hence, the table which has the total on the top and the entities on the bottom line would be the answer which is Option A.

Answer:

A

Step-by-step explanation:

Thursday is x because she sold x oranges. Friday is 2x because she sold double the amount she sold on Thursday. Then we add them together to make 108.

Step-by-step explanation:

A line plot that forms a straight line indicates a direct relationship between the two variables plotted. A graph that shows less deviation from the line of best fit is a good candidate for linear regression. Line graphs are typically used to show trends over time.

When considering a line plot or any graphical representation of data such as scatter plots or line graphs, the main goal is to uncover the underlying pattern or relationship presented. If the data, when graphed, forms a straight line, it suggests a direct relationship between the variables involved. This implies that as one variable increases, the other variable either increases or decreases by a consistent rate. For instance, if one plot shows a line from (0,8) to (3,2), there's a decrease as the first variable increases. Conversely, a line from (0,2) to (3,2) or from (0,3) to (3,3) suggests no change, indicating a directly horizontal line and therefore no relationship. When determining good candidates for linear regression, a scattering of points closely aligned in a straight line pattern, with little deviation from the line of best fit, is indicative of such. Linear regression is more accurate when the variance around the line of best fit is minimal, as seen in the second graph described. Line graphs specifically are useful for showing data trends over time, where the x-axis typically represents time and the y-axis represents another variable.

The sum of the interior angles of a triangle is equal to 180 degrees. Using this property, we can solve for the unknown angle in the triangle. In this case, the unknown angle is x. By setting up an equation and solving for x, we can determine that the value of x is B) 21.

The answer is B. 21.

The sum of the angles in a triangle is 180 degrees. So, we have the following equation:

(5x+14) + 40 + x = 180

Combining like terms, we get:

6x + 54 = 180

Subtracting 54 from both sides, we get:

6x = 126

Dividing both sides by 6, we get:

x = 21

Therefore, the value of x is 21.

Aiko has -$5.50 after buying the candles.

To find out how much money Aiko has after buying candles, we need to calculate the total amount spent on the candles and subtract it from the initial $20.

Aiko initially had $20. She returned 2 candles for $4.75 each, so she got back 2 x $4.75 = $9.50.

Then, she bought 3 candles for $3.50 each, which amounts to 3 x $3.50 = $10.50.

Finally, she bought 1 candle for $5.00.

The total amount spent on candles is $4.75 x 2 + $3.50 x 3 + $5.00 = $9.50 + $10.50 + $5.00 = $25.50.

To calculate how much money Aiko has left, we subtract the total spent from the initial amount: $20 - $25.50 = $-5.50.

Therefore, Aiko owes $5.50 after buying the candles.

Multiply 9k and 8k. After that, you will get 72k² because there are two k numbers. so you leave +7 and put that in the equation then you get 72k²+7.

The area of parallelogram is 108 square inches

Solution:

The formula for area of parallelogram is:

[tex]Area = base \times height[/tex]

From given,

[tex]Base = 1\frac{1}{2}\ feet = \frac{2 \times 1 + 1}{2} = \frac{3}{2}\ feet[/tex]

[tex]Height = 6\ inches[/tex]

Convert feet to inches

1 feet = 12 inches

[tex]\frac{3}{2}\ feet = \frac{3}{2} \times 12\ inches = 18\ inches[/tex]

Therefore, area of parallelogram is:

[tex]Area = 18 \times 6\\\\Area = 108[/tex]

Thus area of parallelogram is 108 square inches

9 * 44 =

9 (40 + 4) =

9(40) + 9(4) =

360 + 36 = 396

Final answer:

To mentally calculate 9 x 44, use the distributive property by multiplying 9 by 40 and 9 by 4, then adding the results to get 396.

Explanation:

The question asks how to mentally calculate 9 x 44 using the distributive property. To do this, you can break down the multiplication into simpler parts. First, use the distributive property to express 44 as the sum of 40 and 4. Multiply 9 by each part:

9 x 40 = 360

9 x 4 = 36

Then, add the two results together:

360 + 36 = 396

So, 9 x 44 equals 396.

Step-by-step explanation:

When you put the number where x is, you get ...

  -14 > -17 . . . . a true statement

Since this statement is true, x=-14 is a solution.

The number -14 is a solution to the inequality X > -17 in mathematics as it falls within the range of numbers greater than -17.

In the realm of mathematics, inequalities define a range of values that can be a solution. In this case, the inequality is X > -17. This means any number greater than -17 is a solution to the inequality. If we consider -14, it falls within this range because -14 is greater than -17. Therefore, yes, -14 is a solution to the given inequality.

Answer: 8 squared equals 8 plus 56

Step-by-step explanation:

What you would do is find a number squared that is greater than 56. I used 8 because 8 squared is 64. So i squared that and got 64, I then subtracted 8 from 64 because you would need to use the same x value in the equation and that lead me t getting 56. All in all x=8.

The solution for equation is x = -6

Solution:

Given equation is:

[tex]5(x-2) + (-9) = -7(1-x)[/tex]

We have to solve the equation

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right

Therefore, solve for brackets in given equation

[tex]5(x-2) + (-9) = -7(1-x)\\\\5x - 10 -9 = -7 + 7x[/tex]

Solve for terms in left hand side of equation

[tex]5x - 19 = -7+7x[/tex]

Move the variables to one side and constants to other side

[tex]7x -5x = -19+7\\\\2x = -12\\\\Divide\ both\ sides\ by\ 2\\\\x = -6[/tex]

Thus the solution for equation is x = -6

x ≤ 12

Solution:

Let us take the number be x.

A number : x

A number divided by three : [tex]$\frac{x}{3}[/tex]

A number divided by three less two : [tex]$\frac{x}{3}-2[/tex]

A number divided by three less two is at most two : [tex]$\frac{x}{3}-2\leq 2[/tex]

Now, simplify the inequality,

[tex]$\Rightarrow\frac{x}{3}-2\leq 2[/tex]

Add 2 on both sides of the inequality,

[tex]$\Rightarrow\frac{x}{3}-2+2\leq 2+2[/tex]

[tex]$\Rightarrow\frac{x}{3}\leq 4[/tex]

Multiply by 3 on both sides of the equation,

[tex]$\Rightarrow\frac{x}{3}\times3\leq 4\times3[/tex]

[tex]$\Rightarrow x\leq 12[/tex]

Hence x ≤ 12.

Final answer:

The question requires setting up an inequality to express the condition 'a number divided by three less two is at most two.' The solution of the inequality reveals that the number in question is any number less than or equal to 12.

Explanation:

The student's question involves a number theoretical concept that requires setting up and solving an inequality. To understand the requirement of 'at most two' when a number is divided by three and reduced by two, we would establish an inequality as X / (3-2) ≤ 2, where X is the unknown number. This inequality represents the condition mentioned in the question, which restricts the value of X to a certain range after the operations are performed.

When working through the inequality, we aim to isolate X to determine the possible values it can hold. Here, we would start by adding two to both sides of the inequality to remove the subtraction, leading to X / 3 ≤ 4. Multiplying both sides by 3 gives us X ≤ 12. This tells us that the number in question is any number that is less than or equal to 12.

Understanding mathematical operations and the interpretation of numerals in context is necessary to solve such problems. Specifically, discerning the difference between an 'at least' and 'exactly' reading of numerals impacts the formation and solution of such inequalities.
