Answer:
21 square feet
Step-by-step explanation:
A cube has 6 faces, therefore 126/6 = 21 sq/ft the area of 1 face
The area of one face of a cube is 21 feet.
What is the surface area of cube?Surface area of cube is the sum of areas of all the faces of cube, that covers it.
The formula for surface area is equal to six times of square of length of the sides of cube.
A cube has a surface area of 126 feet.
The area of one face is given by;
[tex]\rm Area \ of \ one \ face=\dfrac{Surface \ area}{Total \ number \ of \ faces}\\\\ Area \ of \ one \ face=\dfrac{126}{6}\\\\ Area \ of \ one \ face=21[/tex]
Hence, the area of one face of a cube is 21 feet.

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.

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]

identify the graph of 2x^2 + 4xy + 4y^2 = 0 then find theta to the nearest degree.
Answer: 2x2 + 4xy + 4y2 = 0
2 xx + 4xy + 4yy = 0
...xx + 2xy + y*y + yy = 0
(x + y)^2 + yy = 0
if x is a constant
... 2yy + 4xy - 2xy + xx = 0
(2yy + 4xy + 2xx -2xx) - 2xy + xx = 0
2(y + x)^2 - 2xx - 2xy + xx = 0
2(y + x)^2 - xx - 2xy = 0
2(y + x)^2 - xx - 2xy +yy - yy = 0
(x + y)^2 + yy = 0
x = i*y - y
if x = r cos a
y = r sin a
cos a )^2 + cos a sina + sin a)^2 + sin a)^2 = 0

A triangular prism is 19 yards long and has a triangular face with a base of 18 yards and a height of 12 yards. The other two sides of the triangle are each 15 yards. What is the surface area of the triangular prism?
Answer:
1128 Yard²
Step-by-step explanation:
From the question,
The surface area of a triangular prism is
A = bh+H(a+b+c)...................... Equation 1
Where a = First side of the triangular face, b = base of the triangular face, c = the other side of the triangular face, H = heigth of the prism, h = height of the triangular face
Given: a = 15 yard, b = 18 yards, c = 15 yards, h = 12 yards, H = 19 yards.
Substitute these values into equation 1
A = (18×12)+ 19(15+15+18)
A = 216+19(48)
A = 216+912
A = 1128 Yard²
Hence the surface area of the triangular prism is 1128 yard²

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.
