Answer:

Step-by-step explanation:

volume of one cube = ½×½×½ = ⅛ cm³

volume of prism = 5×3×6 = 90 cm³

90/(⅛) = 720 cubes to fill the prism.

volume of bottom layer of cubes = 5×3×½ = 7.5 cm³

7.5/(⅛) = 60 cubes on the bottom layer

Each layer is ½ cm in height

6 cm × (1 layer)/(½ cm) = = 12 layers

perimeter = 2×5 + 2×3 = 16 cm

Determine whether the following is a statistical question. In general how tall are giraffes? Help please

pashok25 [27]

it is a statistical question due to you having to collect data to answer this question, you'd have to collect data on how tall the giraffes are and i'm sure they all don't grow up to be the same height so there will be differentiations in heights of all.

<u>Answer:</u>

x = 5.00 cm

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

• area of the rectangle = $x$ x $(x + 1)$

= $x^2 + x$

• area of the circle = π r²

= $\frac{22}{7}$ x $(x + 2)^2$

= $\frac{22}{7}$ x $(x^2 + 4x + 4)$

∴ $x^2 + x$ + $\frac{22}{7}$ x $(x^2 + 4x + 4) = 184$

⇒ $x^2 + x$ + $\frac{22}{7} x^2 \space\ + \space\ \frac{88}{7} x \space\ + \space\ \frac{88}{7} = 184$

⇒ $\frac{29}{7}x^2 \space\ + \space\ \frac{95}{7}x \space\ - \frac{1200}{7} = 0$

• Using quadratic formula, where

a = $\frac{29}{7}$

b = $\frac{95}{7}$

c = $\frac{-1200}{7}$ ,

$x=\frac{-b \pm \sqrt{b^2-4c}}{2}$

$x = \frac{-\frac{95}{7}\pm \sqrt{(\frac{95}{7})^2 - 4(\frac{29}{7})(\frac{-1200}{7} ) } }{2(\frac{29}{7})}$

$x = 5.00 \space\ \space\ \space\ or \space\ \space\ \space\ x = -8.28$

As length (x) cannot be a negative number,

x = 5.00 cm

Complete the solution table from left to right for the quadratic function. (I did not select an answer, that was a mistake) Than

Karo-lina-s [1.5K]

Answer: OPTION D

Step-by-step explanation:

To complete the table, you need to substitute the values of "x" given in the table into the quadratic equation $y=x^{2}-x-6$ to obtain the corresponding value of "y".
