Find the distance between B (3,−4) and C (5,−5). Round to the nearest tenth, if necessary.

The value of the constant of variation is 130

Constant of variation can be defined as the ratio between two variables in  an inverse variation on a direct variation.

From the information given, we have that;

The number of hours is x

The temperature is y

x α 1/ y

x = k/y

k = xy

Substitute the values

k = 2 × 65

k= 130

Thus, the value of the constant of variation is 130

The dimensions of the playing field the width is 54 yards and the length is 210 yards.

Given that the perimeter of the rectangular playing field is 528 yards and the length of the field is 6 yards less than quadruple the width.

Let the width of the rectangular playing field is x yards and it is given that the length of the field is 6 yards less than quadruple the width means the length is 4x-6.

As we know that the perimeter of the rectangle is two times the sum of length and breadth so.

P=2(l+w)

As it is given that the perimeter is 528 yards.

So, we will substitute all the values in the formula, we get

528=2(4x-6+x)

528=2(5x-6)

528=10x-12

528+12=10x-12+12

540=10x

540/10=10x/10

54=x

Now, substitute this values in l=4x-6 to find the length, we get

l=4(54)-6

l=216-6

l=210

Hence, the dimension of the playing field when the perimeter of the rectangular playing field is 528 yards is width is 54 yards and length is 210 yards.

a)

Solution,

Given,

Cost for 1 pen = $ 1.50

= 1.50×100 cents

= 150 cents

Cost for 1 ruler = 80 cents

No. of Pens needed to be bought = x

No. of rulers needed to be bought = x+10

Now,

Cost for x pens = x×150 cents

= 150x cents

Cost for (x+10) rulers = (x+10)×80 cents

= 80x cents+800 cents

Then,

Total cost = 150x cents+(80x cents+800 cents)

= 150x cents+80x cents+800 cents

= 230x cents+800 cents

= $(230x ÷ 100)+$(800 ÷ 100)

The triangle formed by the feet of angle bisectors of a triangle with a single angle measure of 120° is the Right Triangle.

So,

In triangle ABC, ∠A = 120°.

As a result, DE is the exterior angle bisector of ABCD.

Similarly, for the ABC, F is ex-center because AB is the exterior angle bisector and CF is the interior angle bisector.

As a result, DF is the exterior angle bisector.

BC is a straight line.

So, DEF is the right triangle.

This problem is related to solving an algebraic equation.

In algebra there are many types of equations such as linear equation in one variable and two variable.

Here we have been given two variables and two equations which means we can solve the equation. To solve an equation in algebra it is important that the number of unknowns is equal to the number of equations given.

Given, m/1=2x+3 i.e., m=2x+3

also m/2=3x+7 i.e., m=6x+14

Now equating both the values of m;

  2x+3=6x+14

⇒6x-2x=3-14

⇒4x=-11

∴ x= -(11/4)

Harry's speed on the freeway is 67 miles per hour

Time Harry drove on freeway = 3 hours

Time Harry drove on country road = 6 hours

Total distance covered by him = 483 miles

Let his speed be x miles per hour

Formula to be used:

Speed*Time = Distance

Therefore, the distance covered by him on the freeway  = 3x -----(1)

Distance covered by him on country road = 6(x - 20)------(2)

Formulating the equations using (1) and (2)

3x + 6(x-20) = 483

3x + 6x - 120 = 483

9x = 603

x = 67 miles per hour

Combinations:

Combinations defines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Given,

Pizza pies with a choice of any of 4 toppings: pepperoni, mushrooms, green peppers, or sausage.

Here we need to find how many different pizzas can you make with anywhere from 0 to 4 toppings.

Here we need to assume that each pizza can have at most 1 serving of each topping.

Here we have four level of toppings like no serving, single serving, double serving and triple serving.

Suppose you had one topping, let's say mushrooms.  How many different possible pizzas would there be?

If you understand the setup right, there would be 4: no topping, single mushrooms, double mushrooms, or triple mushrooms.

Similarly, imagine that there are two toppings, mushrooms and sausage.

Then, there are 4 x 4 = 16 different combinations with two items.

We could continue this for a long time.  

If you have only sausage, mushroom, pepperoni and onion, then for a total of

Answer: x= 33

Step-by-step explanation: hope this helps!!!

First of all, every number in each row is odd, so we can eliminate 392 and 394.

The number of elements in each row forms an arithmetic sequence:

• 1st row : 1 element

• 2nd row : 3 elements - and 3 - 1 = 2

• 3rd row : 5 elements - and 5 - 3 = 2

• 4th row : 7 elements - and 7 - 5 = 2

and so on, so that the [tex]n[/tex]-th row has [tex]1 + 2(n-1) = 2n - 1[/tex] elements.

This means that in [tex]n-1[/tex] complete rows, there is a total of

[tex]\displaystyle \sum_{i=1}^{n-1} (2i-1) = n^2 - 2n + 1[/tex]

elements, so that the first element in the subsequent [tex]n[/tex]-th row is the [tex](n^2-2n+2)[/tex]-th number in the sequence {1, 3, 5, 7, …}, i.e the [tex](n^2-2n+2)[/tex]-th odd positive integer. To compute the sum, I use the following well-known formulas.

[tex]\displaystyle \sum_{i=1}^n 1 = n[/tex]

[tex]\displaystyle \sum_{i=1}^n i = \frac{n(n+1)}2[/tex]

Now, the [tex]n[/tex]-th term of the sequence {1, 3, 5, 7, …} is simply [tex]2n-1[/tex], the [tex]n[/tex]-th odd positive integer. So the first element in the [tex]n[/tex]-th row is

[tex]2(n^2-2n+2) - 1 = 2n^2 - 4n + 3[/tex]

and hence the 1st element of the 15th row is

[tex]2\cdot15^2 - 4\cdot15 + 3 = \boxed{393}[/tex]

Step-by-step explanation:

it all starts with having a good definition for a

a = 3x + 6

for the definition of b we need to transform the second equation

x = 1/3 b - 2 = b/3 - 2

3x = b - 6

3x + 6 = b

remember, if a = c and b = c, then it must be a = b.

that is the whole principle here. the symmetric property.

I am not sure what you must do here. so you select on the left the number of the step in the proof ?

if so, then

statement reason : number 1

a = 3x + 6 and 3x = b - 6 division : number 2

a = 3x + 6 and -b = -3x - 6 subtraction : number 3

a = 3x + 6 and b = 3x + 6 division : number 4

a = b = 3x + 6 symmetric : number 5

always remember, every change needed on one side of an equation we need to do on both sides, otherwise the equation is destroyed.

number 2 is "division" as division is a form of multiplication (and multiplication a form of division). we are multiplying by 3.

number 3 subtracts b and also 3x.

number 4 divides by -1.

and number 5 is the fished proof as mentioned above.
