Answer:

33 Cubic inches

Step-by-step explanation:

The volume, in cubic inches, of the second cylinder is,

⇒ 210 inches³

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Chandni compares two cylinders. Both cylinders have an identical base.

Now, The first cylinder has a height of 4 inches and a volume of 120 cubic inches.

And, The second cylinder has a height of 7 inches.

Let the volume, in cubic inches, of the second cylinder is, x

Hence, We can formulate;

120 / 4 = x / 7

⇒ 120 × 7 = 4x

⇒ 4x = 840

⇒ x = 210 inches³

Thus, The volume, in cubic inches, of the second cylinder is,

⇒ 210 inches³

Answer:

  1354.7 square inches

Step-by-step explanation:

The area of a regular n-sided polygon with side length s can be found using the formula ...

  A = n·s²/(4·tan(180°/n))

For n=12 and s=11, the area is ...

  A = (12(11²)/(4·tan(15°)) ≈ 1354.7 . . . . square inches

Answer:

[tex]Area = 1353.9 \: {inches}^{2} [/tex]

Hint :

Area of a Regular Dodecagon

A = [tex]3 {s}^{2} (2 + \sqrt{3} )[/tex]

Answer :

The area of a regular dodecagon with 11-inch sides = [tex]3 {(11)}^{2} (2 + \sqrt{3} )[/tex]

[tex]Area = 3( {11)}^{2} (2 + \sqrt{3}) \\ = 3 \times 121 \times 3.73 \\ = 1353.9 \: {inches}^{2} [/tex]

Question isnt well formatted :

Answer:

1 : 6

Step-by-step explanation:

Given the question :

3x = 1/2y

3x = y/2

Multiply both sides by 2

3x * 2 = y/2 * 2

6x = y

This can be interpreted as :

y = 6 times the value of x

x = y/6

x : y

Answer:

108 cm²

Step-by-step explanation:

the surface area is the sum of all individual shapes areas on the surface.

2 right-angled triangles

3 rectangles

area of a right-angled triangle is At = a×b/2

At = 4×3/2 = 6 cm²

we need it twice : 12 cm²

one rectangle (length×width) = 8×3 = 24 cm²

one rectangle = 8×4 = 32 in²

one rectangle = 8×5 = 40 cm²

total surface area

A = 12+24+32+40 = 108 cm²

an area is always a square unit (power of 2).

a volume is always a cubic unit (power of 3).

and a length is always a simple unit (power of 1).

Uniform would most likely be characteristics of the histogram obtain.

A histogram is a rough representation of the distribution of numerical data. The term was first coined by Karl Pearson.

The histogram is the width of the area covered by the x-axis bars. These are approximate values ​​because the histograms show the bin values ​​instead of the original data values.

If a histogram is bell-shaped, it can be modestly described by its center and width. The center is the location of its axis of symmetry. The spread is the distance between the center and one of its inflection points.

Answer: there are total 100,000 5-digit PINs.

Three Possible outcomes          Associated X values

            00001                                          1

Step-by-step explanation:

Here,  X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits.

Possible number of outcomes = 10 x 10 x 10 x 10 x 10

= 100,000

Possible outcomes          Associated X values

Answer: [tex]\dfrac{32}{3}[/tex]

Step-by-step explanation:

Given

The parabolas are [tex]x^2=2y[/tex] and [tex]y^2=16x[/tex]

Find the point of intersection of two parabolas

[tex]\Rightarrow \left(\dfrac{x^2}{2}\right)^2=16x\\\\\Rightarrow x^4=64x\\\Rightarrow x(x^3-64)=0\\\Rightarrow x=0,4[/tex]

Obtain y using x

[tex](x,y)\rightarrow (0,0)\ \text{and }(4,8)[/tex]

Area enclosed between the two is

[tex]\Rightarrow I=\int\limits^4_0 ({4\sqrt{x}-\dfrac{x^2}{2}}) \, dx\\\\\Rightarrow I=\left ( 4\times \dfrac{2}{3}x^{\frac{3}{2}}-\dfrac{x^3}{2\times 3} \right) _0^4\\\\\Rightarrow I=\left ( \dfrac{8}{3}\times 8-\dfrac{4^3}{6} \right )-0\\\\\Rightarrow I=\dfrac{128-64}{6}\\\\\Rightarrow I=\dfrac{64}{6}\\\\\Rightarrow I=\dfrac{32}{3}[/tex]

Thus, the area bounded by the two parabolas is  [tex]\dfrac{32}{3}[/tex] sq. units.

Answer:

1 is false

2 is true

Step-by-step explanation:

The solution is the coordinate where the two lines intersect

For the first image the two lines intersect at (3,5) therefore (0,4) is not a solution to the system of equations

For the second image the lines intersect at (1,-2) therefore the statement is true

Answer:

Ok to find the surface area of this cylinder first we need the circumference to find this we do C=πd

C=3.14*18

C=56.52

now we have to multiple this by the height of two

113.04

now we have to find the area of the bottom to do this we do A=πR^2

A=3.14*81

A=254.34

multiple this by two for the two sides we get

508.68

now we add this to 113.04 we get

621.72

since I used 3.14 instead of more digits of pie we can round this up so the answer is C.

Answer:

x = 60

Step-by-step explanation:

The sum of the angles in a triangle is 180

40 + x+20 + x = 180

Combine like terms

2x+60 =180

Subtract 60 from each side

2x+60-60 =180-60

2x =120

Divide by 2

2x/2 =120/2

x = 60
