A cylinder has a height of 20 centimeters and a radius of 11 centimeters. What is its volume? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answer:

Area = 114 m2

Step-by-step explanation:

Area of the Figure = Area of Rectangle ABCD - Area of Rectangle HGFE

Area of the Figure = 12*14 - 9*6 = 168 - 54 = 114

Answer:

70%

Step-by-step explanation:

We can first find the fraction

35/50

We know that percent is out of 100 so multiply the top and bottom by 100

35/50 * 2/2 = 70/100

The percent is 70%

Answer:

Step-by-step explanation:

Given two points, the equation for the line through them can be found using the slope formula and the slope-intercept form.

The slope formula is ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -(-4))/(0 -6) = 8/-6 = -4/3 . . . . slope of the line

The y-intercept is 4, given by the second point.

The slope-intercept equation for a line is ...

  y = mx +b . . . . . . line with slope m and y-intercept b

  y = -4/3x +4 . . . . . line with slope -4/3 and y-intercept 4

__

The x-intercept can be found by solving for x when y=0.

  0 = -4/3x +4

  0 = 4x -12 . . . . multiply by -3

  0 = x -3 . . . . . . divide by 4

  3 = x . . . . . . . . subtract 3

The x-intercept is (3, 0).

__

The line can be graphed by plotting the given points and drawing the line through them.

Answer:

Slope: [tex]-\frac{4}{3}[/tex]

Y int. : (0,4)

X int. : (3,0)

Step-by-step explanation:

Equations to remember:

[tex]y = mx + b\\\\\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

--------------------------------------------

[tex](x_{1}, y_{1}) = (6, -4)\\\\(x_{2}, y_{2}) = (0,4)[/tex]

--------------------------------------------

SLOPE

You want to set up your equation for finding slope like this:

[tex]\frac{4 - (-4)}{0 - 6}[/tex]

4 - (-4) will become 4 + 4. This is because there is a -1 in front of the parenthesis.

A negative number times a negative number will always equal a positive number.

[tex]-\frac{8}{6}[/tex]

when simplified/divided by 2, which is the number you want:

[tex]-\frac{4}{3}[/tex]

This is your slope or your m in y = mx + b

---------------------------------------------------------------

Y INTERCEPT

Use one of your points.

I'll use (0,4) as an example.

Set up your equation like this:

[tex]4 = -\frac{4}{3}(0) + b[/tex]

Since your slope is being multiplied by ZERO, you can just eliminate your mx or slope.

This means that 4 = b!

That's your Y Int, which you'll find was one of the given points, (0,4).

---------------------------------------------------------------

From there, if you use a graph, you should find that your X Int is (3,0).

Answer:

[tex]y=5x+15[/tex]

Step-by-step explanation:

Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs [tex](x_1,y_1)\rightarrow(5,40)[/tex] and [tex](x_2,y_2)\rightarrow(12,75)[/tex]:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5[/tex]

Thus, our equation so far is [tex]y=5x+b[/tex]. Next, we need to find our y-intercept, [tex]b[/tex], which represents our flat fee. We do so by using one of our original given ordered pairs:

[tex]y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b[/tex]

Therefore, our final equation for the function is [tex]y=5x+15[/tex]

Answer:

  A)  7/5

Step-by-step explanation:

An exponential equation like this can be solved by using logarithms, or by rewriting the bases so they are the same.

  3^(2h-1) = 27^(-h+2)

Using 27 = 3^3, we can write the equation in terms of powers of 3:

  3^(2h-1) = (3^3)^(-h+2)

  3^(2h -1) = 3^(-3h +6)

Equating exponents gives ...

  2h -1 = -3h +6

  5h = 7 . . . . . . . . . add 1+3h

  h = 7/5 . . . . . . . divide by 5

__

Additional comment

When solving this using a graphing calculator, it is often convenient to write the equation in such a way that the solution is an x-intercept. Here, we can do that by subtracting the right-side expression from both sides:

  3^(2h-1) -27^(-h+2) = 0

The solution is h = 1.4 = 7/5.

Answer:

h=7/5

Answer:

£3.15 (nearest pence)

Step-by-step explanation:

If the price of a coffee has increased by 7% then the final price of the coffee is:  100% + 7% = 107% of the original price.

Therefore, to find the original price of the coffee:

  original price ÷ 107 × 100

= 3.37 ÷ 107 × 100

= £3.15 (nearest pence)

Answer:

I will need a photo to answer this

Step-by-step explanation:

Kindly, please upload a photo, TQ!

Answer:

Using the equation form y = MX + b where a is the slope of the line and b is the y-intercept.

The line that is parallel this the line with equation 5x + y = 11 will have the SAME SLOPE as this line BUT the y-intercept will be -8 (as stated in the problem.)

Rewrite 5x + y = 11 to the standard form to yield the slope of that line.

So 5x + y = 11 becomes y = -5x + 11 where the slope is -5.

So the equation of the line that you want is then...y = -5x - 8. It satisfies both conditions.

Answer:

Measure of ∠WOV = 60°

Complementary angles

Step-by-step explanation:

       The box shows us that is equal to 90°. Angles ∠WOV and ∠WOX are complementary angles because we get 90° when we add them together. Since we are given the measure of ∠WOX we can subtract it from 90° to find the measure of ∠WOV.

90° - 30 ° = 60°

Answer:

Surface Area = [tex]530yd^2[/tex]

Step-by-step explanation:

*This answer is for the problem on the left that seems unanswered*

Firstly, you must understand that the surface area of an irregular polygon like the one in the problem must be found by dividing its faces into rectangles and finding the sum of the areas of those rectangles.

Another way to say this is that the surface areas of these solids can be found by adding up the areas of the rectangles that make their faces.

You will see that I attached a picture that divides the solid's faces into subsections, labelled a through i, including faces that are not visible in the diagram.

If you divided the solid's faces in the same way as the picture, the surface area is found as follows:

[tex]Area_A=12*7=84yd^2\\Area_B=12*4=48yd^2\\Area_C=12*4=48yd^2\\Area_D=4*4=16yd^2\\Area_E=11*3=33yd^2\\Area_F=12*3=36yd^2\\Area_G(notVisible)=12*11=132yd^2\\Area_H(notVisible)=12*7=84yd^2\\Area_I(notVisible)=Area_E+Area_D=33+16=49yd^2[/tex]

By the way, [tex]yd^{2}[/tex] is the same as "square yards".

After finding the areas of each rectangle, add them all up to get your final answer:

[tex]SurfaceArea=530yd^2[/tex]
