What percent of 12 is 7 written out

Answer:

h(6) = 13

Step-by-step explanation:

Functions! One of my favorites to answer :)

h(x) = 2x + 1

So, now we plug in h(6). Remember that when we replace the x with the number, we replace it in the right side of the equation as well:

h(6) = 2(6) + 1

Now we multiply 2 * 6:

h(6) = 12 + 1

Now 12 + 1:

h(6) = 13, final answer.

Hope this helps :D

Answer: 13

Step-by-step explanation:

h(x) = 2(x) + 1

h(6) = 2(6) + 1 = 12 + 1 = 13

Velocity of tugboat is -5 miles/hour .

The velocity of an object is the change in position (displacement) over a time interval. Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive.

Given,

Displacement by tugboat = - 1.5 miles

Time taken in travelling = 0.3 hours

Velocity = Displacement/ Time

              = - 1.5 / 0.3

              = - 5 miles/hours

Hence, -5 miles/hour is Velocity of tugboat.

Answer:

A and D

Step-by-step explanation:

Given the function:

[tex]\displaystyle{f(x)=\sqrt{5-x^2}}[/tex]

In order to find the first-order derivative of square root function, we have to convert the form of surd to exponent form. Therefore:

[tex]\displaystyle{f(x)=\left(5-x^2\right)^{\frac{1}{2}}}[/tex]

Since the exponent is a constant and that the base is an expression with variable, we can apply the chain rule (power rule variation):

[tex]\displaystyle{f(x) = u^n \to f'(x) = nu^{n-1} \cdot \dfrac{du}{dx}}[/tex]

Therefore:

[tex]\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{\frac{1}{2}-1} \cdot \dfrac{d}{dx}\left(5-x^2\right)}\\\\\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{\frac{1}{2}-\frac{2}{2}} \cdot \dfrac{d}{dx}\left(5-x^2\right)}\\\\\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{-\frac{1}{2}} \cdot \dfrac{d}{dx}\left(5-x^2\right)}[/tex]

Deriving 5 - x²:

[tex]\displaystyle{\dfrac{d}{dx}\left(5-x^2\right) = 0 - 2x^{2-1}}\\\\\displaystyle{\dfrac{d}{dx}\left(5-x^2\right) = -2x}[/tex]

Thus:

[tex]\displaystyle{f'(x)=\dfrac{1}{2}\left(5-x^2\right)^{-\frac{1}{2}} \cdot (-2x)}\\\\\displaystyle{f'(x)=\dfrac{1}{2}(-2x)\left(5-x^2\right)^{-\frac{1}{2}} }\\\\\displaystyle{f'(x)=-x\left(5-x^2\right)^{-\frac{1}{2}} }[/tex]

You can also convert to the square root form of:

[tex]\displaystyle{f'(x)= \dfrac{-x}{\sqrt{5-x^2}}}[/tex]

Therefore, A and D are correct.

well, we can simply find how much for each tulip in each store.

store left has them for £9.8 for 4, that means 9.8 / 4 = 2.45, so £2.45 for each tulip.

store right had them for £4.2 each, but they went down by 1/3, so hmm a whole is 3/3 so if we take away 1/3 from 3/3, 3/3 - 1/3 = 2/3, so the new discounted price is really 2/3 of £4.2, that's (2/3) * 4.2 = 2.8, so £2.8 each.

so store left has them cheaper, doesn't matter at a dozen or less or more.

how much is it at store left for 12?  12 * 2.45 = 29.4, or £29.4.

Answer:

The task is to calculate the total amount spent by Mr. Spendalot. To do this, you need to calculate the amount of inventory purchased, apply the discount, calculate the sales tax, and add the tip. Here's one way to do it:

Calculate the amount of inventory purchased: 31% of $1,000,000 is 31/100 * $1,000,000 = $310,000

Determine the discount: Based on the purchase amount of $310,000, Mr. Spendalot qualifies for a discount of 10%. So, the discount is $310,000 * 10% = $31,000.

Calculate the sales tax: 8.5% of the purchase amount after discount is 8.5/100 * ($310,000 - $31,000) = $2,067.50

Add the tip: 15% of the purchase amount after discount and sales tax is 15/100 * ($310,000 - $31,000 + $2,067.50) = $52,101.13

Calculate the total: The total amount spent by Mr. Spendalot is ($310,000 - $31,000 + $2,067.50 + $52,101.13) = $393,168.63.

So, the total amount spent by Mr. Spendalot is $393,168.63.

Step-by-step explanation:

Determine the amount of purchase before discount: Mr. Spendalot bought 31% of Mr. Shine's inventory, which is $1,000,000. Therefore, his purchase before discount is 31% of $1,000,000, or $310,000.

Calculate the discount: Based on the information in the discount table, Mr. Spendalot's purchase qualifies for a 40% discount. Therefore, the discount amount is $310,000 * 40%, or $124,000.

Determine the amount of purchase after discount: After getting the 40% discount, Mr. Spendalot's purchase is $310,000 - $124,000, or $186,000.

Calculate the sales tax: Mr. Shine charged an 8.5% sales tax on Mr. Spendalot's purchase after discount. Therefore, the sales tax amount is $186,000 * 8.5%, or $15,791.

Determine the tip: Mr. Spendalot gave Mr. Shine and his staff a 15% tip on his purchase after discount and sales tax. Therefore, the tip amount is $186,000 + $15,791 * 15%, or $31,328.

Calculate the total cost: Adding up the purchase after discount, sales tax, and tip, we get the total cost of $186,000 + $15,791 + $31,328, or $233,119.

Conclusion: Mr. Spendalot's total purchase cost is $233,119.

The task requires you to calculate the total amount spent by Mr. Spendalot at Mr. Shine's store Ice Box. Mr. Shine has an inventory worth $1,000,000 which he marks up by 150%. Mr. Spendalot bought 31% of this inventory, and was given a discount based on the amount he spent:

Spend 100k+ and get 10% off

Spend 250k+ and get 20% off

Spend 500k+ and get 30% off

Spend 750k+ and get 40% off

Spend 1 million+ and get 50% off

After the discount, Mr. Spendalot was charged 8.5% sales tax. He also left a 15% tip for Mr. Shine and his staff. Your goal is to calculate the total amount spent by Mr. Spendalot.

A linear regression curve is built on the equation y=mx+b. The y-intercept is m, and the slope is B. The previous sentence is sometimes referred as a "mathematical equation merging multiple variables," even if y or y are independent parts. The only variables in bivariate linear equations are two. There are no known solutions to application issues involving linear equations. Y=mx+b, also written as mx+b, is the expression for a straightforward system of equations.

Here,

Given :

From a mixed number, you must convert it to a decimal number. You can do this by following the instructions below:

In order to start, you must reduce the fraction's denominator by its numerator.

Step 2: You must now multiply the resulting quotient by the whole number component.

You therefore obtain:

=> 7 1/4 = 7 + 0.25 = 7.25

The scale picture that transforms "Figure a" into "Figure b" is then: 1: 71

The specified length of the appropriate side of "Shape a" must then be multiplied by in order to determine the value of "z."

Step-by-step explanation:

I just answered this.

the first group is consistent independent, because both equations are lines with different slope. so, they have 1 intersection, which is the solution.

the second group is consistent dependent, because both equations describe the same line.

multiply the second equation by -2, or divide the first equation by -2, and you see they are identical. multiplying an equation by a factor on both sides does not change the equation or function.

so, as both lines are identical, every point on the line is an intersection and solution. therefore, there are infinitely many solutions.

the third group is inconsistent.

they represent 2 lines with identical slope but different y-interceptions. so, they are parallel and have no intersection or solution at all.
