Volume formula is [tex]V = B \cdot h[/tex]
First find the area of the base (hexagon). The area of a hexagon can be found with the formula [tex]A = \frac{1}{2} P\cdot a[/tex] where [tex]a[/tex] is the apothem (line that's perpendicular to a side and connected to the center point) and [tex]P[/tex] is the perimeter.
We already know the length of the apothem (5.7 ft). We also have one side length already (6.58 ft), a hexagon has 6 sides, so [tex]P = 6\cdot 6.58 = 39.48[/tex] ft.
Plug these into the area formula
[tex]A = \frac{1}{2} (39.48)(5.7)[/tex]
Area of the base ([tex]B[/tex]) is 112.52 ft
Now plug into the volume formula using 15.4 ft as the height
Final answer:
[tex]V = 1732.81 ft^3[/tex]

A bakery recorded the number of muffins and bagels it sold for a seven day period. For the data presented, what does the value of 51 summarize?
A) mean of bagels
B) mean of muffins
C) range of bagels
D) range of muffins
Answer:
Mean of bagel
Step-by-step explanation:
Working out each of the statically summaries Given in the option :
Mean of muffin :
Mean = Σx / n
n = sample size
(61 + 20 + 32 + 58 + 62 + 61 + 56) / 7
= 350 / 7
= 50
Mean of bagel :
Mean = Σx / n
n = sample size
(34 + 45 + 43 + 42 + 46 + 72 + 75) / 7
= 357 / 7
= 51
Hence, from the result obtained, we could see that the value of 51 summarizes the mean of bagel.

24. Woodworking A birdhouse has a square base with
side length 3x - 4. What polynomial in standard
form represents the area of the base?
Answer:
9x² - 24x + 16
Step-by-step explanation:
Formula for the area of the square base = s²
Where,
s = side length = 3x - 4
Therefore:
Area of the base = (3x - 4)²
Expand
(3x - 4)(3x - 4)
3x(3x - 4) -4(3x - 4)
Apply the distributive property
9x² - 12x - 12x + 16
Add like terms
9x² - 24x + 16
Area of the base in standard form = 9x² - 24x + 16
Answer:
9x^2 -24x +16 units^2
Step-by-step explanation:
(3x-4)^2 = 9x^2 -24x +16
x^2+3x

Answer:
Option D
Step-by-step explanation:
McKenzie wants to put the soil in a box with the soil height = (10 - 2) inches
(As she plans to keep 2 inches from the top of the box empty)
Length of the box = 8 inches
Width of the box = 12 inches
Since, soil in the box will get the dimensions same as of the box but the height will be 2 inches less than the box height.
Therefore, volume of the soil = Length × Width × height
V = 8 × 12 × (10 - 2)
Option D will be the answer.

300 x .90= 270 students
25 points! Please show work for brainlest answer
Answer:
x² - 10 + 2x = 2x + 90
x² - 10 + 2x - 2x = 2x - 2x + 90
x² - 10 = 90
x² - 10 + 10 = 90 + 10
