Answer:

Area of the enclosed figure = 3148.74 [tex]m^{2}[/tex]

Step-by-step explanation:

Area enclosed by the figure = 2 x area of the semicircle + area of the square

For the semicircle,

radius = [tex]\frac{diameter}{2}[/tex]

          = [tex]\frac{42}{2}[/tex]

          = 21 m

area of a semicircle = [tex]\frac{1}{2}[/tex] x [tex]\pi r^{2}[/tex]

                                = [tex]\frac{1}{2}[/tex] x 3.14 x [tex](21)^{2}[/tex]

                                = 692.37 [tex]m^{2}[/tex]

area of a square = length x length

                            = 42 x 42

                            = 1764 [tex]m^{2}[/tex]

Thus,

area enclosed by the figure = 2 x 692.37 + 1764

                                              = 3148.74 [tex]m^{2}[/tex]

The total area enclosed bu the figure is 3148.74 [tex]m^{2}[/tex]

Answer:

I agree with Jamie

Step-by-step explanation:

Given the inequality expression -2°C > -5°C, to compare both temperatures, we are to determine whether we agree or disagree with him.

Note that negative values that are closer to zero on the number line are greater than those that are far from zero. Hence, since -2 is closer to zero on the number line than -5, this means that -2 is greater than -5 hence I agree with Jamie's temperature value comparison.

Step-by-step explanation:

step 1. since we have a right triangle we can use trigonometry

step 2. <A: 5 is the opposite and 8 is the hypotenuse so we use sine

step 3. sinA = opp/hyp = 5/8

step 4. A = 38.68° using inverse sine on your calculator.

Answer:

162 km per hour

Step-by-step explanation:

Hi!

Speed=Distance x Time

So... 3 x 54 = 162

Hope this helps :)

Answer:

18km/h

Step-by-step explanation:

Well. Speed = Distance x Time

So if she travelled for 3 hours. In that time, she must have travelled 54km.

Average speed is given as kilometres per hour or km/h

So all we need to do is 54/3 which gives us 18km/h

I hope that helps! ^-^

Answer:

x = 34

Step-by-step explanation:

according to the problem ::

(2x + 9)° + (3x + 1)° = 180° [ since, the opposite angles of a cyclic quadrilateral are supplementary ]

or, 2x + 9 + 3x + 1 = 180

or, 2x + 3x = 180 - 10

or, 5x = 170

or, x = 170 / 5

or, x = 34

therefore, the value of x is 34°

Answer:

m = 5

Step-by-step explanation:

Given

2(m + 1) = 3(m - 1) ← distribute parenthesis on both sides

2m + 2 = 3m - 3 ( subtract 2m from both sides )

2 = m - 3 ( add 3 to both sides )

5 = m

Answer:

B = 155°, C = 25°, D = 155°

Step-by-step explanation:

Assuming you require B, C, D

A and B are adjacent angles and are supplementary , that is

A + B = 180°

25° + B = 180° ( subtract 25° from both sides )

B = 155°

A and C are vertically opposite angles and are congruent, then

C = 25°

B and D are vertically opposite angles and are congruent , then

D = 155°

Answer:

4) D) 20

3) A) 16°

Step-by-step explanation:

4)

You must follow the correct order of operations.

13 - 2(1 - 15)/4 =

Do the subtraction inside the parentheses first.

= 13 - 2(-14)/4

Now multiply -2 by -14.

= 13 + 28/4

Divide 28 by 4.

= 13 + 7

Finally, add.

= 20

Answer: D) 20

3)

The sum of the measures of the angles of a triangle is 180°.

Let the unknown angle have measure x.

x + 41° + 123° = 180°

x + 164° = 180°

x = 16°

Answer:

A) 16°

Answer:

2x 2 x 2 x 2= 8 + 1 = 9?

Step-by-step explanation:

The solution of the equation 2x + 1 = 9 will be 4.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The equation is given below.

2x + 1 = 9

Simplify the equation, then we have

2x + 1 = 1

2x = 9 - 1

2x = 8

x = 8 / 2

x = 4

The solution of the equation 2x + 1 = 9 will be 4.
