Answer:

4 x 4 1/2 = 18

4 x 4 1/2 = 18

4 1/2 - 2 = 2.5

8 3/4 x 2.5 = 21 7/8

18 + 18 + 21 7/8 = 57 7/8

B : 57 7/8

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:

y+5/4 = x

Step-by-step explanation:

I think that this will get really messy if you integrate with respect to y.

Here is what I suggest you do.

=2+82−5y=2x+8x2−5

Evaluated at =1y=1 and =5y=5

1=2+82−5=21=2x+8x2−5x=2

5=2+82−5=1

5=2x+8x2−5x=1

Answer:

y= 500+7x

Step-by-step explanation:

Given data

Total amount for the rent=  $500

Cost of food per night= $10

Family charges per night=$60

Let the number of nights be x

and let the total charges be y

Hence, the expression for the situation is given as

y=500+10x+60x

y= 500+7x

Answer:

Triangle A and Triangle B

Answer:

m<D = 26

Step-by-step explanation:

<D = x

x + 122 + 32 = 180

x + 154 = 180

x = 180 - 154

x = 26

Answer:

Step-by-step explanation:

<D + 122° + 32° = 180° ( being sum of angles of triangle )

< D = 180° - 154°

< D = 26°

The value of the given equation is 124.

Since the equation is [tex]2a^3 - a[/tex] and a = 4

So, the value of a is

[tex]= 2a^3 - a\\\\= 2(4)^3 - 4\\\\= 128 - 4[/tex]

= 124

Hence, The value of the given equation is 124.

Answer:

(5,6)

Step-by-step explanation:

 Initial Coordinate   rotated 180°   is just a sign change    new coordinate

coordinate (x, y)       rotated 180°   is just a sign change     (-x, -y)

if                 (-x, y)      rotated 180°   is just a sign change     (x, -y)

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:

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.

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]
