The perimeter of a rectangle is 28 cm. Which of the following express the area of the rectangle in terms of the width x?

The Perimeter of a triangle ΔABC  is 27.68

Given ABC be triangle having vertices A(-2, -1), B(4, 3), C(-5, 7)

We need to find the perimeter of a triangle as

Perimeter of a triangle ΔABC = AB + BC +CA

Now we need to find distances as

D = √ (x₂ - x₁)² + ( y₂ - y₁ )²

AB = √ (4 - (-2))² + (  3 - (-1) )²

     = √ ( 4 + 2 )² + ( 3+1 )²

    = √ (6)² + (4)²

    = √ 36 + 16

    = √ 52

    = 7.21

BC = √ ((-5) - (4))² + (  7 - (3) )²

     = √ (-5 -4 )² + ( 7-3 )²

    = √ (-9)² + (4)²

    = √ 81 + 16

    = √ 97

    = 9.84

AC = √ ((-5) - (-2))² + (  7 - (-1) )²

     = √ (-5 -2 )² + ( 7+1)²

    = √ (-7)² + (8)²

    = √ 49 + 64

    = √ 113

    = 10.63

Perimeter of a triangle ΔABC = AB + BC +CA

                                                 = 7.21 + 9.84 + 10.63

                                                 = 27.68

Therefore, the Perimeter of the given triangle ΔABC  = 27.68

Hard to explain.

Answer

4 miles

Step-by-step explanation:

The distance traveled in an hour if a person travels at 2/3 miles in 10 mins is 4 miles.

In order words, the total distance which is travelled in one hour if a person travels a journey of 2/3 miles in 10 mins is 4 miles.

The ratio of the parameters given from the above is given below:

2/3 miles in 10 mins

Convert hour to minutes:

let

Equate ratio of distance to time taken

2/3 : 10 = x : 60

2/3 ÷ 10 = x / 60

2/3 × 1/10 = x/60

2/30 = x/60

2 × 60 = 30 × x

120 = 30x

x = 120 / 30

x = 4 miles

Therefore, the distance traveled or covered in an hour if a person travels at 2/3 miles in 10 mins is 4 miles.

Answer:

A. 72°

D. 144°

E. 216°

Step-by-step explanation:

are you tempted to calculate the internal angles ?

that is, I guess, the trap set by your teacher here, and it would be the wrong approach.

nevertheless, quickly just as a reminder :

the sum of all internal angles in a polygon is

(n - 2)×180°

n being the number of sides.

in our case that is

(5 - 2)×180 = 3×180 = 540°

so, each internal angle is 540/5 = 108°.

but we are not turning at an edge or vertex. no, we are turning the pentagon around is central point.

we are running each vertex along a circle arc. the center of that circle being P.

after every 1/5 of the circle arc there is a vertex of the pentagon.

and whenever we rotate one vertex on top of the next one, we carry the pentagon visually onto itself.

so, instead of a full circle rotation we need only 1/5 of that :

360 / 5 = 72°

and with every additional 1/5 of the circle arc (or 72°) we get it again.

that means at

72°

144°

216°

288°

360°

the pentagon carries onto itself.

therefore, A, D and E are correct.

The mathematical expression of the statement is x - 15 <= 5

The statement is given as:

Hourly wage of $15 differs from the average by less than or equal to $5

Let the average hourly wage be x

So, we have:

Hourly wage of $15 differs from the average = x - 15

less than or equal to $5 => <=5

So, the expression is

x - 15 <= 5

Hence, the mathematical expression of the statement is x - 15 <= 5

The maximum and minimum value of η at q = 10 and q = 85 respectively.

The demand equation is p = 190/ (q + 10) where 10 < 0 < 85.

η is the elasticity of demand.

Then, the elasticity of demand is given as:

η = ( dq/ dp) × ( p / q )

Now, we have p = 190/ (q + 10)

Therefore,

p ( q + 10 ) = 190

pq + 10p = 190

q = ( 190 - 10p ) / p

Now,

dq / dp = ( d/dp ) ( ( 190 - 10p ) / p )

dq / dp =  ( -190/ p² )

Substituting these values in the elasticity demand,

η = ( dq/ dp) × ( p / q )

η = ( -190/ p² ) × ( p / q )

η = ( -190/ pq )

η = ( -190/ [190 / (q + 10 ) ]q )

η = [ - ( q + 10 ) / q ]

| η | = | - ( q + 10 ) / q |

η =  ( q + 10 ) / q = 1 + 10/q

The critical point is when | η' | = 0.

η' = ( d / dq ) ( 1 + 10/q )

η' = - 10/ q²

- 10/ q² = 0

Hence, - 10/ q² is not defined.

Therefore, the function is not defined at q = 0.

Therefore, q = 0 is not a solution.

We have 10 ≤ q ≤ 85

The value of functions at the endpoint,

At q = 10,

η = ( 1 + 10/q )

η = ( 1 + 10/10 )

η = 1 + 1 = 2

At q = 85,

η = ( 1 + 10/q )

η = ( 1 + 10/85 )

η = 1.11764

Therefore, the absolute value of the elasticity of demand is maximum at q = 10.

The absolute value of the elasticity of demand is minimum at q = 85.

Answer:

The last digit you multiplied by.

Step-by-step explanation:

It's not that hard, but here you go  :)

If you multiplied 12 by 11 you would get 2 as your last digit, because 2 is the last digit of 12. (12x11=132)

So for 123 by 11, following this pattern, 3  is the last digit of 123 so the answer must end in 3. (123x11=1353)

If you still don't get the pattern I'll give you a few more examples here:

If you multiply 1234 by 11 you would get a number ending in 4 because the last digit of 1234 is 4! (1234x11=13574)

So what would be the last digit of 12345?

Answer:

One child weighs 120lbs, and the other weighs 40lbs.

Step-by-step explanation:

Assuming that you meant "Two" instead of "Do", there are two children that weigh 160 pounds together. If we know that one child weighs 120lbs more, we know that the other child has to weigh 40lbs using the equation below where x represents the weight of the second child:

120 + x = 160

Subtract 120 from both sides

x = 40
