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:

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: [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.

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

1 : 6

Answer:

The solution is (2,9)

Step-by-step explanation:

The equations are:

-6x + y = -3

5x - 2y = -8

Elimination:

One of the coefficients(either x or y) must be opposite, so I will multiply the first equation by 2.

-12x + 2y = -6

5x - 2y = -8

Adding the equations:

[tex]-12x + 5x + 2y - 2y = -6 - 8[/tex]

[tex]-7x = -14[/tex]

[tex]7x = 14[/tex]

[tex]x = \frac{14}{7}[/tex]

[tex]x = 2[/tex]

Finding y:

[tex]5x - 2y = -8[/tex]

[tex]5(2) - 2y = -8[/tex]

[tex]2y = 18[/tex]

[tex]y = \frac{18}{2}[/tex]

[tex]y = 9[/tex]

Solution as an ordered pair:

(x,y) = (2,9)

The solution is (2,9)

Answer:

Please post the actual question

Step-by-step explanation:

Thanks

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).

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 :

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]

let garden table be 1 unit.

1 unit + 1 unit+ 56 = 844

2 units+56=844

2 units=844-56=788

1 unit=788 divided by 2 =394

hence, cost of bench = 1 unit+56=394+56=450

Step-by-step explanation:

Answer:

-74

Step-by-step explanation:

f(x) = -2x^2 +8x -10

Let x = -4

f(-4) = -2 ( -4)^2 +8(-4) -10

     = -2(16) -32-10

     = -32 -32-10

    = -74

Answer:

Incomplete question, but you use the normal distribution to solve it, with [tex]\mu = 23.5[/tex] and [tex]\sigma = 3.6[/tex]

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average waiting time to be seated for dinner at a popular restaurant is 23.5 minutes, with a standard deviation of 3.6 minutes.

This means that [tex]\mu = 23.5, \sigma = 3.6[/tex]

Thus

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{X - 23.5}{3.6}[/tex]

Find the probability that the patron will have to wait:

More than X minutes:

1 subtracted by the p-value of Z

Between A and B minutes:

p-value of Z when X = A subtracted by the p-value of Z when Z = B.

Less than X minutes.

p-value of Z.

Step-by-step explanation:

→ P = 2L + 2W

→ P = 2(L + W)

→ P ÷ 2 = L + W

→ (P ÷ 2) - W = L

We can use this formula to to calculate the length.

Answer:

SinA=5/1 3 CosA=12/13 tanA=5/12. SinC=12/13 CosC=5/13 and tanC=12/5

Step-by-step explanation:

Basically find the third side by Pythagorean theorem which would get you 13. So 13 is the hypotenuse. Remember these 3 formulas. Sin=Opposite/Hypotenuse Cos=Adjacent/hypotenuse and Tan=opposite/Adjacent. So for Sin a the opposite side to angle A is 5. The hypotenuse is always the same which would be 13. So Sin a is 5/13. For cos the side adjacent would be 12. So it is 12/13. *Note Hypotenuse cannot be considered the adjacent.

Answer:

sin A = 5/13,  cos A = 12/13,  tan A = 5/12,  sin C = 12/13, cos C = 5/13, tan C = 12/5

Step-by-step explanation:

According to Pythagoras, hypotenuse = √{(12)^2+(5)^2}. So, hypotenuse = 13. (See picture if confused).

sin A = 5/13

cos A = 12/13

tan A = 5/12

sin C = 12/13

cos C = 5/13

tan C = 12/5
