Answer:  £5 = 52 tickets,  £8 = 23 tickets

<u>Step-by-step explanation:</u>

                      Quantity        Cost

£5 Tickets           x                 5x

<u>£8 Tickets   </u>   <u>     y        </u>     <u>    8y    </u>

    TOTAL          75               444

  Cost:     5x + 8y = 444   →  1(5x + 8y = 444)   →    5x + 8y = 444

Quantity:    x +   y =   75   → -5( x +   y =   75)    →  <u> -5x - 5y</u> = <u>-375</u>

                                                                                         3y =  69

                                                                                           y = 23

Input y = 23 into one of the original equations to solve for x:

x +  y  = 75

x + 23 = 75

x         = 52

Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he nee
Alex777 [14]

Answer:

Tristan will need 32 feet of material for the perimeter of the garden.

Step-by-step explanation:

Given that

Area of square garden = A = 64 square feet

Perimeter = P = ?

We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.

So,

Area = A = s^2

s is for side

Putting the value of area

64 = a^2

Taking square root on both sides

\sqrt{s^2} = \sqrt{64}\\s = 8\ feet

The length of side is 8 feet.

Perimeter will be:

P = 4*s\\P = 4*8\\P = 32\ feet

Hence,

Tristan will need 32 feet of material for the perimeter of the garden.

The probability all of the students in this class will be present and on time is 3/10. The probability all of the students are p
cestrela7 [59]

Answer:

3/4

Step-by-step explanation:

A: students present
B: students on time

P(all students present and on time) = P(A and B) = 3/10
P(all students present) = P(A) = 2/5

P(A and B) = P(A).P(B|A) where P(B|A) is the probability of everyone being on time given that everyone is present

So P(B|A) = P(A and B) /P(A) = 3/10 ÷ 2/5 = 3/10 * 5/2 = 15/20 which can be reduced to 3/4 by dividing numerator and denominator by 5

The missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²

How to find the distance between two coordinates?

The formula for distance between two coordinates is;

d = √[(y₂ - y₁)² + (x₂ - x₁)²]

where;

(x₁, y₁) is the coordinate of the first point

(x₂, y₂) is the coordinate of the second point

Now, this distance formula can also be rewritten when we square both sides to get;

(y₂ - y₁)² + (x₂ - x₁)² = d²

Thus, the missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²

Find the inverse function answer to the question in the image attached.
koban [17]

The inverse function is:

g(x) = 27*x^3 - 4

And g(2) = 212.

<h3>How to get the inverse function?</h3>

We need to find g(x) such that:

g(h(x)) = x.

We know that:

h(x) = \frac{\sqrt[3]{x + 4} }{3}

Then our function must be a cubic, multiplied by 3^3 = 27, and then subtracts 4, it is:

g(x) = 27*x^3 - 4

As you can see, if you evaluate in h(x), the outcome is x.

Now we can evaluate this in x = 2, we get:

g(2) = 27*2^3 - 4 = 212

The correct option is C.
