Answer:
4
Step-by-step explanation:
an aquarium is in the shape of a cuboid
the depth can be determined from the volume of a cuboid
volume = length x depth x height
11.96 = 2.5 x 1.1 x depth
depth = 11.96 / (2.5 x 1.1 )
depth = 4.3 feet = 4 (to the nearest whole number)
To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
Simplify the expression to a polynomial in standard form: (4x-1)(3x-2)(x+1)
Answer:
12x^3+x^2-9x+2
Step-by-step explanation:
(4x-1)(3x-2)(x+1)
(12x^2-8x-3x+2)(x+1)
(12x^2+(-8x-3x)+2)(x+1)

Find the volume of this regular hexagonal pyramid
Answer:
83 is the volume according to my best knowledge and remembrance of Geometry. I hope these calculations help!
Step-by-step explanation:
Since a right triangle is established upon the indication of the right angle marking, and the 50 degree marking is apparent around the one of the legs, the resulting angle of the right triangle unidentified is 40 degrees. Now, the formula is 1/3 × (the area of the base) × (the height), where finding the base area dictates that we apply Area = (3√3 s^2)/ 2, where s = side length, (3√3 (4)^2)/ 2 = 24√3, Substitution Property of Equality: 1/3 * 24√3 * x; find x, "the radius of a hexagon is equal to the length of one side" (mathblog), use the cosine ratio because cosine = adjacent over hypotenuse, cos(50) = 4 (according to the length of side equal radius of hexagon)/x = 6, 1/3 * 24√3 * 6 = 48√3 = 83 is the volume.

AB intersects CD at point E. What is the value of X in degrees?
Answer:
x = 132°
Step-by-step explanation:
∠AED and ∠CEB are both vertical angles. Vertical angles will always be equal to each other, so ∠AED = ∠CEB.
Since they're equal, if ∠AED = 132°, then ∠CEB must also equal 132°.
(∠CEB is the x value you're asking about by the way).

Answer: They are related by the AAS postulate and they can be proven congruent.
Step-by-step explanation: You can see that one of the lines on each of the triangle has that little tick which means those lines are congruent. You can also see that for two of the angles one of them has one arc and the other has two arcs for BOTH triangles which makes those two angles congruent. Two angles and one side congruent makes the triangles congruent by the AAS postulate.

A rectangular box has a volume of 15 cubic feet. The length, width, and height of the box are each doubled.
What is the new volume of the rectangular box?
A. 30 cubic feet
B. 60 cubic feet
C. 90 cubic feet
O D. 120 cubic feet
Answer:
it should be D/120
Step-by-step explanation:
An example of the box is:
5 the width
3 the length
1 the height.
That would be 5 x 3 x 1.
To double them, you must multiply each number by 2:
5 x 2 = 10
3 x 2 = 6
1 x 2 = 2.
Now the equation is 10 x 6 x 2.
First multiply 10 x 6 (60).
Then 60 x 2 (120).
120 is the answer

A cube is dilated by a scale factor of 0.75 to create a new cube. The surface area of the new cube is…
Answer:
9/16 of original cube area
Step-by-step explanation:
surface area = 6 * side²
side length after 0.75 dilated: 3/4 of original side length
surface area after dilated : 6 * (3/4)² / 6 * 1² = 9/16

In a small town of 5,832 people, the mayor wants to determine the proportion of voters who would support an increase to the food tax. An assistant to the mayor decides to survey 1,000 randomly chosen people to construct a 90% confidence interval for the true proportion of people who would support the increase in food tax. Of the sample, 363 people say they would support the increase. Are the conditions for inference met?
Yes, the conditions for inference are met.
No, the 10% condition is not met.
No, the randomness condition is not met.
No, the Large Counts Condition is not met.
Answer:
No, the 10% condition is not met is the answer.
1,000/5,832 is 0.1714, or ~17%, which is more than 10% of the population.
No, the 10% condition is not met.
Ratio:
'Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.'
Proportion:
'A proportion is an equation in which two ratios are set equal to each other.'
According to the given problem,
Total number of people in the town = 5832
Number of people to be surveyed = 1000
Ratio of number of people chosen to the total population = [tex]\frac{1000}{5832}[/tex]
= 0.17
Therefore percentage of people to be surveyed = 0.17 × 100
= 17%, which is more than 10%
Hence, we can conclude that the 10% condition is not met.

The walls of a farm silo form a hexagonal prism as shown. What is the volume of the silo?
The volume of the silo is ___
The volume of silo is 4840.22 cubic units.
What is hexagonal prism?
A hexagonal prism is a 3-D figure that has two hexagonal bases that are parallel to each other. A hexagonal prism is a prism with hexagonal base and top. This polyhedron has 8 faces, 18 edges, and 12 vertices. Out of the 8 faces, 6 are rectangles, and 2 are hexagons.
For the given situation,
The silo is in a form a hexagonal prism.
The base edge of the silo, a = 9 ft
The height of the silo, h = 23 ft
The formula of volume of the hexagonal prism is
[tex]V=\frac{3\sqrt{3} }{2}a^{2}h[/tex]
Substitute the above values,
⇒ [tex]V=\frac{3\sqrt{3} }{2}(9^{2})(23)[/tex]
⇒ [tex]V=4840.215[/tex] ≈ [tex]4840.22[/tex]
Hence we can conclude that the volume of silo is 4840.22 cubic units.
