what is the surface area of a cylinder with a 3 m radius and a 13 m height ?

Answer:

[tex]\huge\boxed{\sf{\displaystyle\frac{2}{15}}}[/tex]

Step-by-step explanation:

Hello.

In order to solve for c, we need to take the square root of both sides.

What is the square root?

It's the opposite of squaring.

Here, c is squared (multiplied by itself) so in order to isolate it, we need to take the square root of both sides.

Remember the Golden Rule of Algebra:

Whatever we do to one side, we do to the other.

Take the square root:

[tex]\sf{\sqrt{c^2}=\sqrt{\displaystyle\frac{4}{225}[/tex]

[tex]\sf{c=\displaystyle\frac{2}{15}[/tex]

I hope it helps.

Have a nice day.

Answer:

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.

6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Answer:

80$ (maybe 85)

Step-by-step explanation:

combined rate =20$/hour

It can take 85 minutes for you and your friend to mow 2 acres. 35+50=85. So 85*3 (because 6/2=3) is the number of minutes you work. 255 minutes. So 4.25 hours. If you are only being paid for hours, then you will make $80. If you are being paid the extra minutes the $85. I believe that the answer you should pick is $80.

Answer:

$41.18

Step-by-step explanation:

35/50 = 0.7

Therefore, in the time it takes you mow 1 acre, your friend mows 0.7 acres

Therefore, for every 35 minutes = 1 + 0.7 = 1.7 acres are mowed by you and your friend combined.

⇒ 1.7 ÷ 35 = 0.04857142... acres mowed every minute

⇒ 6 ÷ 0.04857142...  = 123.5294118... minutes to 6 acres

Therefore, it takes 35/17 hours for you and your friend to mow 6 acres

If your rate is $20 per hour, then 35/17 x 20 = $41.18

Divide the hexagon into 6 equal streak triangles which would have side length equal to the radius of the circle.

the area of an equal lateral triangle = sqrt(3)/4 x radius^2

the area of the hexagon would be 6 x sqrt(3)/4 x radius^2

Area = 6 x sqrt(3)/4 x 8^2 = 166.2768 square feet

rounded to the nearest whole foot = 166 square feet.

Answer:

28.72

Step-by-step explanation:

The area for the 8 inch diameter cake is 50.27

1/4·π·8^2

but the area for the 10 inch diameter cake is 78.54

1/4·π·10^2 = 78.54

All you do to find the difference is

78.54 - 50.27 which is 28.72

Answer:

2y>18......

2(8)= 16>18 no

2(11)= 22>18 yes

2(12)= 24>18 yes

2(6)= 12>18 no

Answer:

Step-by-step explanation:

We have 4 value of y : 8 ; 11 ; 12; 6

To determine whether it is a solution to the inequality 2y > 18, we have to substitute these values in

Substitute 8 in, we get : 2 x 8 > 18
16 > 18 (not true)
So, this is not a solution


Substitute 11 in, we get : 2 x 11 > 18
21 > 18 (true)
So, this is a solution

Substitute 12 in, we get : 2 x 12 > 18
24 > 18 (true)
So, this is also a solution

Substitute 6 in, we get : 2 x 6 > 18
12 > 18 (not true)

So, this is not a solution

There are 2 values that satisfy this inequality for y : 11 and 12

Using the definition of angles on a straight line, the measure of angle BEC is: 62°.

Angles that lie on a straight line add up to 180 degrees.

Thus, given that EB bisects ∠AEC, therefore:

m∠BEC = 1/2(180 - m∠CED)

Plug in the values

m∠BEC = 1/2(180 - 56)

m∠BEC = 1/2(124)

m∠BEC = 62°

Thus, using the definition of angles on a straight line, the measure of angle BEC is: 62°.

The direction of Beatriz relative to the starting point of her trip is approximately [tex]278.806^{\circ}[/tex].

[tex]\vec r = \vec r_{1} + \vec r_{2}[/tex] (1)

Where:

If we know that [tex]\vec r_{1} = (200\,km \cdot \cos 300^{\circ}, 200\,km\cdot \sin 300^{\circ})[/tex] and [tex]\vec r_{2} = (150\,km\cdot \cos 250^{\circ}, 150\,km\cdot \sin 250^{\circ})[/tex], then final position of Beatriz relative to origin is:

[tex]\vec r = (48.670, -314.159)\,[km][/tex]

And the direction relative to the starting point ([tex]\theta[/tex]), in degrees, is found by following inverse trigonometric relation:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, out of 87 + 5 + 24 = 116 customers, 87 paid with case, hence the probability as a decimal is given by:

p = 87/116 = 0.75.

  - Asymptote line is a line that the graph tends to approach but never intersects.

From the information we have, first - draw both vertical asymptote and horizontal asymptote to make it easier to draw a graph.

Then draw a rational function’s graph as it tends to 0 when x = 0 and -1 when x tends to both sides of infinity.

You should receive a graph below that I made, see the attachment. The purple line represents the horizontal asymptote and y-axis is our vertical asymptote.

8,736m squared

Step-by-step explanation:

ok so if the park drawing has sides measuring 9.1cm by 12cm, and our scale is 1cm=80m we can solve as follows:

area of the model is length x width = 9.1x12=109.2cm squared

now we know 1cm=80m and we have 109.2cm so we can multiply 109.2cm by 80m to get the area of the actual park which is 8,736m squared

Answer:

27°

Step-by-step explanation:

we have the 'opposite' as length 2 is opposite the angle θ

we have the adjacent (length 4) which is next to the angle θ

the hypotenuse is the longest side (we don't need)

Using SOHCAHTOA

we use TOA as O is opposite and A is adjacent

tanθ = opposite ÷ adjacent

tanθ = 2 ÷ 4

using the inverse sign to find θ

θ = tan⁻¹(2/4) = 27° (to the nearest whole degree)

its 0.37
