Express 55 miles per hour in kilometers per hour?

Answer:

138π m²

Step-by-step explanation:

The following data were obtained from the question:

Diameter (d) = 6 m

Height (h) = 20 m

Surface Area (SA) =?

Next, we shall determine the radius. This can be obtained as follow:

Diameter (d) = 6 m

Radius (r) =?

r = d/2

r = 6/2

r = 3 m

Finally, we shall determine the surface area of the cylinder. This can be obtained as follow:

Radius (r) = 3 m

Height (h) = 20 m

Surface Area (SA) =?

SA = 2πrh + 2πr²

SA = 2πr (h + r)

SA = 2 × π × 3 (20 + 3)

SA = 2 × π × 3 × 23

SA = 138π m²

Thus, the surface area is 138π m².

I think that the answer is d.

Answer:

correct answer is D

Answer:

She was paid $550 and made a profit of $50.

Step-by-step explanation:

Given that:

Amount invested by Kayla = $500

Amount returned = 110%

Amount returned = [tex]\frac{110}{100}*500[/tex]

Amount returned = 1.1 * 500

Amount returned = $550

Profit made by Kayla = 550 - 500

Profit made by Kayla = $50

Hence,

She was paid $550 and made a profit of $50.

Answer:

[tex]\displaystyle \frac{69}{110}[/tex]

Step-by-step explanation:

Decimal to Fraction Conversion

We have the number

N=0.62727272...

Multiplying by 10:

10N=6.272727

Multiplying by 100:

1000N=627.2727

Subtracting the last two equations, the periodic part cancels out:

1000N - 10N = 627 - 6

Operating:

990N = 621

Dividing by 9:

110N = 69

Dividing by 110:

[tex]\displaystyle N=\frac{69}{110}[/tex]

Answer:

2.50 x 4 + 4²

or

2.50 x 4 + 4 x 4

and

$26

Step-by-step explanation:

So first we have to find how much the folders and notebooks were by themselves so our first equation is:

2.50 x 4 = 10

and

4 x 4 = 16

and then we add the costs

10 + 16 = 26

So Wendy spent $26 on folders and notebooks

Answer:

linear equation

Step-by-step explanation:

straight line form in the graph infinitely

Answer:

Step-by-step explanation:

Given that:

[tex]f(x) = x tan ( \dfrac{1}{x})[/tex]

For continuity; [tex]\lim \limits_{x \to 0^-} f(x) = \lim \limits_{x \to 0^+} f(x) = f(0)[/tex]

Now;

[tex]\lim \limits_{x \to 0^-} f(x) = \lim \limits_{x \to 0^-} xtan (\dfrac{1}{x})[/tex]

[tex]= \lim \limits_{x \to 0^-} \dfrac{tan (\dfrac{1}{x})}{\dfrac{1}{x}}[/tex]

[tex]= \lim \limits_{x \to 0^-} \dfrac{tan (\dfrac{1}{0})}{\dfrac{1}{0}}[/tex]

[tex]= \dfrac{\infty}{\infty} \to intermediate \ form[/tex]

Using L'Hospital Rule

[tex]\lim \limits _{x \to 0^-} [ x \ tan (\dfrac{1}{x})] = \lim \limits _{x \to 0^-} \dfrac{\dfrac{d}{dx} \ tan \dfrac{1}{x} }{\dfrac{d}{dx} \dfrac{1}{x} }[/tex]

[tex]= \lim \limits _{x \to 0^-} \dfrac{sec^{1} (\dfrac{1}{x}) * \dfrac{-1}{x^2} }{\dfrac{-1}{x^2} }[/tex]

[tex]= \lim \limits _{x \to 0^-} sec^{1} (\dfrac{1}{x})[/tex]

[tex]= sec^1(\dfrac{1}{0})[/tex]

[tex]=sec^1 (\infty) \to[/tex] not defined

∴

[tex]\lim \limits _{x \to 0^- }[x \ tan (\dfrac{1}{x})] \ne 0 = f(0)[/tex]

Hence, f(x) is not  continuous.

Answer:

49.02 ft

Step-by-step explanation:

See the attached picture for a diagram.

Since the angle is 35 degrees and the only side length we know is the 75 ft long length of the kite (which is the hypotenuse), you would use sin(35) = x/75 where x is the side opposite of the 35 degree angle. Solve for x by doing sin(35) * 75, which equals 43.01823... Make sure you add 6ft from the height of the man. This would make the kite's total height above the ground 49.01823... Round according to the directions you've been given.

Hence , kite flies  49.01 above the ground is the kite

The angle of elevation is a widely used topic in trigonometry that deals with height and distance. It is defined as the angle formed by the horizontal plane and the oblique line connecting the observer's eye to an object above him. This angle is eventually generated above the surface. The angle of elevation is made in such a way that it is above the observer's eye, as the name implies.

Given angle of elevation is 35degrees

hypotenuse=75 and perpendicular=x

Hence [tex]sin 35^{0}[/tex]=[tex]\frac{x}{75}[/tex]

[tex]sin 35^{0}*75[/tex]=x

49.01=x

Hence , kite flies  49.01 above the ground is the kite

Add y+x and maby that's u answer

Step-by-step explanation:

Answer:

it is 385$ because if you divide 70 by 2 you get 35 which is your constant rate so then you divide 77 by 7 to get the number of weeks(11) so then you multiply 11x35 to get the answer of 385

Step-by-step explanation:

70 divided by 2 = 35

77 divided by 7 = 11

35 times 7 = 385

Answer:

C. 385

Step-by-step explanation:

2/70 first you find out the rate by dividing both top and bottom by 2 and you get

1/35 that means every week he is saving $35

77 days = 11 weeks

so you do 11 * 1 = 11 and

11*35 which gets you

385

Answer:

x = -8

Step-by-step explanation:

(4 · x) - (4 · 6) + 6 = 6x - 2

4x - 24 + 6 = 6x - 2

4x - 18 = 6x - 2

Isolate x.

4x = 6x - 2 + 18

4x = 6x + 16

4x - 6x = 16

-2x = 16

x = 16 ÷ -2

x = -8

I hope this helps! :)

Answer:

-8 =x

Step-by-step explanation:

4(x - 6) + 6 = 6x-2​

Distribute the 4

4x - 24 +6 = 6x-2

Combine like terms

4x - 18 = 6x-2

Subtract 4x from each side

4x-18-4x = 6x-2-4x

-18 = 2x-2

Add 2 to each side

-18+2 = 2x-2+2

-16 = 2x

Divide each side by 2

-16/2 =2x/2

-8 =x

Answer:

[tex]y=78[/tex]

[tex]\frac{y}{13}=6[/tex] (Simplify)

[tex]\frac{y}{13}*13=6*13[/tex] (Multiply both sides of the equation by [tex]13[/tex] to get rid of the denominator)
