Answer: [tex]x= \frac{-1+\sqrt{97} }{8} , \frac{-1-\sqrt{97} }{8}[/tex]

Step-by-step explanation:

Use the Quadratic Formula .. if you use Completing the Square it'll take longer!!

In general, given [tex]ax^{2} +bx+c=0[/tex] , there exists two solutions where:

[tex]x=\frac{-b+\sqrt{b^{2} -4ac} }{2a}[/tex] , [tex]\frac{-b-\sqrt{b^{2} }-4ac}{2a}[/tex]

In this case, a=4 , b=1 and c= -6

[tex]x= \frac{-1+\sqrt{1-4*4*-6} }{2*4}[/tex] , [tex]\frac{-1-\sqrt{1-4*4*-6} }{2*4}[/tex]

Simplify.

[tex]x=\frac{-1+\sqrt{97} }{8}[/tex] , [tex]\frac{-1-\sqrt{97} }{8}[/tex]

Answer:

[tex]42cm^2[/tex]

Step-by-step explanation:

Well there are 6 faces on a cube and if each face is 7, the total should be 42.

The surface area of the cube is A = 42 cm²

The formula for surface area of a cube is equal to six times of square of length of the sides of cube. It is represented by 6a2, where a is the side length of cube.It is basically the total surface area.

Surface area S = 6a² ,

where a is the side of the cube

Given data ,

Let the surface area of cube be A

Now , the value of A is

Let the area of one face S = 7 cm²

So , Surface area A = 6a²

On simplifying , we get

A = 6 x 7 cm²

A = 42 cm²

Hence , the surface area is 42 cm²

Step-by-step explanation:

Let's put this statement into words: Fabiola’s dog is 5 pounds heavier than one-third of the weight of Luisa’s dog. Fabiola’s dog weighs 23 pounds.

This is an equation representing the weight of Fabiola's dog:

[tex]\frac{1}{3}[/tex]f + 5 = 23

I honestly have no idea what the diagram is supposed to mean, it'd be great if you could provide a picture :), then I'll edit my answer.

1

tail -- 6

7

The required Sample space = {(h, 1), ( h, 6) (h ,7 ), ( t, 1 ), ( t, 6 ), ( t, 7 )}.

Given that,
There are 3 balls in a hat; one with the number 1 on it, one with the number 6 on it, and one with the number 7 on it. You pick a ball from the hat at random and then you flip a coin. Using a tree diagram, To obtain the sample space.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

a coin has 2 sample space = {H , T}
H = head and T = tail
a hat with three balls has sample space {1, 6, 7}
Now, a ball picks from the hat at random and then flips a coin
Sample spaces
              H                    T
      -----------------    ---------------
      1       6      7      1      6    7
Implies
Sample space = {(h,1), (h,6) (h,7), (t,1), (t,6) (t,7)}

Thus, the required Sample space = {(h,1), (h,6) (h,7), (t,1), (t,6) (t,7)}.

Answer:

6. The relationship is they multiply the first box of glasses by the amount of boxes 15glasses = x 3,

30 glasses = x6

45 glasses = x 9

60 glasses = x 12

75 glasses = x15

= 30, 45, 60,75

But in between glass amount 45 +60 they show a midpoint amount of glasses in a box where 45 = 9n  then 55 = 11n and stands out as  11 boxes as an offset amount of glasses where 5 are in each box.

7. Robert is incorrect as 25 x 5 = 125 and not 120

as 120 and 125 glasses can be divided to check

125/25  = 5 and could be correct if he wanted spare glasses = 1 spare box.

But when we check 120/25 =  4.8 so this would be too many boxes as he would only need 24 boxes.

24 x 5 = 120 glasses.

⇒ The number of ice cream cones in the lot = 4

    The total number of items in the lot = 14

    Probability = the number of that particular item in the lot ÷ the total     number of items in the lot.

    Probability = 4/14 = 2/7

2) Soccer Ball = 1/7

⇒ The number of soccer balls in the lot = 2

    The total number of items in the lot = 14

    Probability = the number of that particular item in the lot ÷ the total number of items in the lot.

    Probability = 2/14 = 1/7

3) Books = 5/14

⇒The number of books in the lot = 5

    The total number of items in the lot = 14

    Probability = the number of that particular item in the lot ÷ the total number of items in the lot.

    Probability = 5/14

4) Coins = 3/14

⇒ The number of coins in the lot = 3

    The total number of items in the lot = 14

    Probability = the number of that particular item in the lot ÷ the total number of items in the lot.

Answer:

x = 7.3

Step-by-step explanation:

We're going to use the formula for the area of a triangle:

Area = 1/2 x base x height

We can see that the height of the triangle is 10, but we don't know what the base length is.

We know that one of the angles is 54 °, so we're going to use SOH CAH TOA to work out the length of the base.

We're using the height and the base, which are the opposite (O) and adjacent  (A) sides relative to our angle. According to SOH CAH TOA we'll use tan (T).

The equation is tan(Ф°) = O/A, where Ф is our angle (54°), O is our opposite side (10), and A is our adjacent side. Since we don't know what A is we'll use x.

tan (54°) = 10/x

Multiply both sides of the equation by x.

x tan (54°) = 10

Divide both sides of the equation by tan(54°).

x = 10/tan(54°)

Use your calculator to solve for x.

x = 7.265

To the nearest tenth, x = 7.3

Answer:

It is non function

Step-by-step explanation:

because the x values repeated, the input ( x values) produce more than one output.

This is not a function because for a value of x the value of the y comes out to be two.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The set of ordered pairs are as given below.

{(19,15),(−25,0),(−16,11),(−2,12),(−16,14),(−13,20)}

The relation to be a function for each value of the x the value of the y should be unique.

This is not a function because for a value of x the value of the y comes out to be two.
