Answer:

  11.85 deciliters

Step-by-step explanation:

Your table tells you 1 cup is 0.237 liters. Then 5 cups is ...

  (5 cups)(0.237 L/cup) = 1.185 L = 11.85 dL

__

"deci-" is the SI prefix for 1/10. 1.1 liters is 11 tenths of a liter.

Answer:

gradient is 0.35

Step-by-step explanation:

The gradient or slope of the line is 1/4.

The slope of a line indicates the direction and the steepness of the line. The formula for the slope of a line passing through the points (x₁,y₁) and (x₂, y₂) is m = (y₂-y₁)/(x₂-x₁).

The graph of the line is given.

Note that the line passes through the point (0,1) ad (4,2).

The gradient of the line is nothing but the slope of the line.

The slope of the line is:

m = (2-1)/(4-0)

m = 1/4

Hence, the gradient or slope of the line is 1/4.

Answer:

2,400 minutes and its is 144,000 secods

Step-by-step explanation:

Answer:

Let the price of one senior citizen ticket be sc and the price of one student ticket be st.

Let's write equations using the information given and the variables above:

=> 5sc + 15st = $137.50

=> 20sc + 44st = $430

Hmm.. We can multiply 5sc by 4 to get 20sc.

=> 4(5sc) + 4(15st) = 4($137.50)

=> 20sc + 60st = $550

Now we can subtract the second equation from the first to determine the price of a student ticket.

  20sc + 60st = $550

-  20sc + 44st = $430

=> 16st = $120

=> st = $7.5

So, the price of a student ticket is $7.5.

Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.

Step-by-step explanation: The figure below shows the area in question.

Area of a circle is given by

[tex]A=\pi.r^{2}[/tex]

The walkway is a semicircle. Then, area will be:

[tex]A=\frac{\pi.r^{2}}{2}[/tex]

The area that will be covered with glass is the area between the outer and the inner circles. So, area is

[tex]A_{t}=A_{outer}-A_{inner}[/tex]

[tex]A_{t}=\frac{\pi.r_{o}^{2}}{2}- \frac{\pi.r_{i}^{2}}{2}[/tex]

[tex]A_{t}=\frac{\pi}{2}(32.5^{2}-22.5^{2})[/tex]

[tex]A_{t}=\frac{\pi}{2}(550)[/tex]

[tex]A_{t}=[/tex] 864

To cover the Skywalk floor is needed 864[tex]ft^{2}[/tex] of glass.

Step-by-step explanation:

4) ΔSTW ≅ ΔBFN . So, corresponding parts of congruent triangles are congruent.

a) BN = SW                                        d) m∠W = m∠N

  BN = 9 cm                                           m∠W = 82°

b) TW = FN                                        e) m∠B = m∠S

TW = 14 cm                                            m∠B = 67°

c) BF = ST                                          f) m∠B + m∠N + m∠F = 180°

  BF = 17 cm                                                 67 + 82 + m∠F = 180

                                                                            149 + m∠F = 180

                                                                                     m∠F = 180 - 149

                                                                                      m∠F = 31°          

5) ΔUVW ≅ ΔTSR

UV = TS

12x - 7 = 53

   12x   = 53+7

   12x = 60

      x = 60/12

      x = 5

UW =TR

3z +14 = 50

    3z = 50 - 14

   3z = 36

     z = 36/3

    z = 12

SR =VW

5y - 33 = 57

     5y = 57 + 33

     5y = 90

       y = 90/5

       y = 18

7) ΔPHS ≅ ΔCNF

∠C = ∠P

4z - 32 = 36

      4z = 36 + 32

       4z = 68

        z = 68/4

       z = 17

∠H = ∠N

6x - 29 = 115

  6x     = 115 + 29

      6x = 144

        x = 144/6

       x = 24

∠P + ∠H + ∠S = 180   {Angle sum property of triangle}

36 +115 + ∠S = 180

      151   + ∠S = 180

                ∠S = 180 - 151

               ∠S = 29°

∠F = ∠S

3y - 1 = 29

   3y = 29 + 1

  3y = 30

    y = 30/3

    y = 10

8) ΔDEF ≅ ΔJKL

DE = 18    ;  EF = 23

DF = 9x - 23

JL= 7x- 11

DF = JL           {Corresponding parts of congruent triangles}

      9x - 23 = 7x - 11

9x  - 7x - 23 = -11

        2x - 23 = -11

               2x = -11 + 23

               2x = 12

                 x = 12/2

                x = 6      

JK   = DE           {Corresponding parts of congruent triangles}

3y - 21  = 18

       3y = 18 + 21

25 is divided by 5 and the remainder is 5, So,

3×5 = 15,

Now,

15 > 14,

So, the product of ([tex]\frac{3}{5}[/tex] × 25) is greater than 14

The answer is -9

Step-by-step explanation:

First we have to find the value for g(8) so that we can plug its solution into f(x).

So...

[tex]\frac{1}{8}[/tex](8) + 5

1 + 5

6

So now we plug in 6 into f(x) since 6 was our solution to g(x)

3 - 2(6)

Answer:

[tex]\frac{d}{dx}(-xcos3x)= 3x \ sin(3x)- cos(3x)[/tex]

Step-by-step explanation:

Use the Product Rule for derivatives, which states that:

In the function we are given, [tex]f(x)=-x \cos3x[/tex], we can break it up into two factors: -x is being multiplied by cos3x.

Now, we have the factors:

Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.

Now let's apply the product rule to f(x) = -xcos3x.

Simplify this equation.

Multiply x and 3 together and remove the parentheses.

Therefore, this is the derivative of the function [tex]f(x)=-xcos3x[/tex].

Hi there!

[tex]\large\boxed{f'(x) = -cos3x + 3xsin3x}[/tex]

[tex]f(x) = -xcox3x\\\\\text{Use the product rule and chain rule to solve for the derivative:}\\\\\frac{dy}{dx}= -cos3x + (-x * (-sin3x) * 3)\\\\= -cos3x + 3xsin3x[/tex]

Actually Welcome to the Concept of the Absolute value.

so we get as,

let, y = 2 - 9i

so the absolute value is |y|

[tex] |y| = \sqrt{ {2}^{2} + {9}^{2} } [/tex]

so we get as,

|y| =

[tex] \sqrt{81 + 4} = \sqrt{85} [/tex]

so the absolute value is

[tex] \sqrt{85} [/tex]
