Mult. $7.25 by 4 times 4 (4 PIZZAS per week, for 4 weeks):

$7.25(4)(4) = $116

Fine dining: 2($85) = $170

So, the fine dining costs more!

A rectangular prism with a volume of 666 cubic units is filled with cubes with side lengths of \dfrac12 2 1 start fraction, 1,

Arada [10]

Answer:

48 cubes.

Step-by-step explanation:

Let n represent number of cubes with each side $\frac{1}{2}$ units.

We have been given that a rectangular prism with a volume of 6 cubic units is filled with cubes with side lengths of $\frac{1}{2}$ units. We are asked to find the number of cubes that will fill the prism.

We know that volume of n cubes will be equal to volume of rectangular prism.

$n\cdot \text{Volume of each cube}=\text{Volume of rectangular prism}$

We also know that volume of a cube with side length 'x' is equal to $x^3$ .

$\text{Volume of each cube}=(\frac{1}{2}\text{ Unit})^3$

$\text{Volume of each cube}=\frac{1^3}{2^3}\text{ Unit}^3$

$\text{Volume of each cube}=\frac{1}{8}\text{ Unit}^3$

$n\cdot \frac{1}{8}\text{ Unit}^3=6\text{ Unit}^3$

$n\cdot \frac{1}{8}=6$

$n\cdot \frac{1}{8}\cdot 8=6\cdot 8$

$n=48$

Therefore, it will take 48 cubes with each side $\frac{1}{2}$ units to fill the prism.

The vertices of abc are a(-2,2) and b(6,2)

Alona [7]

Using the distance formula:

AB^2 = (-2-6)^2 = (2-2)^2
      = 64
    AB = 8 units
BC^2 = (6-0)^2 + (2-8)^2
      = 36 + 36
= 72
BC = 6 root 2
AC^2 = (-2-0)^2 + (2-8)^2
= 4 + 36
= 40
AC = 2 root 10

Perimeter = 8 + 6 root 2 + 2 root 10
   = 2 (4 + 3 root 2 + root 10) units
