Answer:

Large cup cost $4.25

Step-by-step explanation:

Medium:  x

   Large:  y

Constraints:

  7x + 10y = 68.75

  10x + 15y = 101.25

Isolate y variable:

     (7x + 10y = 68.75) * -10    ===>    -70x - 100y =  -687.50

   (10x + 15y = 101.25) * 7       ===>     70x + 105y = 708.75

                                                        ____________________

   add the two equations                                 5y = 21.25

   divide by 5                                                      y = 4.25

Answer:

0.36

Step-by-step explanation:

Given, a circle with radius, r=4 \ cm

Area of circle =\pi r^2

Substitute r=4

Area of whole circle=\pi r^2\\=\pi\times 4^2\\=16\pi \\=50.2654\ cm^2

Square is inscribed in it whose each side is 4\sqrt{2}\ cm

Area of square =side^2\\=(4\sqrt{2} )^2\\=16\times 2\\=32 \ cm^2

We can see that area of the white circle

= area of the whole circle - area of square

=50.2654-32\\=18.2654 \ cm^2

Probability of falling a random point within the white circle

=\frac{area\ of\ white\ circle}{area\ of\ whole\ circle}

=\frac{18.2654}{50.2654} \\=0.3633

Rounding to nearest hundredth.

Probability of falling a random point within the white circle would be 0.36

One number is 9 times another. Their product is 27 times their sum. Find the numbers.
Lyrx [107]

Answer:

270 & 30

Step-by-step explanation:

let the number is n,

the equation :

n× 1/9 n= 27(n +1/9 n)

1/9 n² = 27n + 3n

1/9 n² = 30n

1/9n²- 30n = 0

n(1/9n -30)= 0

n = 0 or

1/9n = 30 => n = 30×9 = 270

270 is a number,

the other : 270/9 = 30
