Answer:

2463 cm^3

Step-by-step explanation:

Given that a cylinder of height of 24cm and base diameter 14cm, a cone having equal radius and height is hollowed out. Find the volume of the remaining solid of the cylinder.

Let first calculate the volume of the cylinder

V = πr^2h

Where the radius = 7 cm

V = π × 7^2 × 24

V = 3694.5 cm^3

Let's calculate the volume of a cone

V = 1/3πr^2h

V = 1/3 × π × 7^2 × 24

V = 1/3 × 3694.5

V = 1231.5 cm^3

To Find the volume of the remaining solid of the cylinder, minus the volume of a cone from the volume of a cylinder

Remaining volume V = 3694.5 - 1231.5

V = 2462.99 cm^3

V = 2463 cm^3 approximately

Answer:

[tex]\dfrac{25}{216}[/tex]

Step-by-step explanation:

From the given information:

The probability (p) of winning a bottle cap = [tex]\dfrac{1}{6}[/tex]

The probability of not winning a bottle cap will be (q) = 1 - p

[tex]= 1- \dfrac{1}{6}[/tex]

[tex]= \dfrac{5}{6}[/tex]

Since we are told that the winning is placed once on every sixth bottle

Then the required probability = P( of not winning the first purchase) × P( of not winning the second purchase) × P( of winning the third purchase)

[tex]= \dfrac{5}{6} \times \dfrac{5}{6} \times \dfrac{1}{6}[/tex]

[tex]= \dfrac{25}{216}[/tex]

Step-by-step explanation:

Answer:

The value of average temperature during that period=[tex]58^{\circ}[/tex]

Step-by-step explanation:

We are given that

Temperature at time t  is given by

[tex]T(t)=50+6t-\frac{1}{3}t^2[/tex]

We have to find the average temperature during a certain  24-hour period.

We know that

Average value of function

[tex]f_{av}=\frac{1}{b-a}\int_{a}^{b}f(x)dx[/tex]

Using the formula

Average temperature during the period

[tex]=\frac{1}{24-0}\int_{0}^{24}(50+6t-\frac{1}{3}t^2)dt[/tex]

[tex]=\frac{1}{24}[50t+3t^2-\frac{1}{9}t^3]^{24}_{0}[/tex]

[tex]=\frac{1}{24}(50\times 24+3(24)^2-\frac{1}{9}(24)^3)[/tex]

[tex]=58^{\circ}[/tex]

Hence, the value of average temperature during that period=[tex]58^{\circ}[/tex]

Two sides of the triangle are the same length, so the two angles of the long side are identical.

The three inside angles total 180, so the sum of the 2 identical angles would equal: 180-70 = 110

x is one of those angles. X = 110/2 = 55 degrees.

X = 55

Answer:

170.6 inches

The scale factor is an enlargement

Step-by-step explanation:

16 by 24 is the Painting by a scale factor of 2.25

A scale factor is an enlargment or reduction in a shape or quantity.

So

(16*24) is the size of the painting after Scale factor

16*24=384

Know get 384/2.25

170.666666667

170.6 inches

Answer:

the answer is c

Step-by-step explanation:

Answer:

8.5 cm

Step-by-step explanation:

We know that the square has side lengths of 6cm. To calculate the distance from one corner of the square to the opposite corner, we are calculating the diagonal of the square.

Along the diagonal is where the square gets split in half into two right triangles. The Pythagorean theorem states that [tex]a^2+b^2=c^2[/tex] where c is the longest side of a right triangle and a and b are the other two sides.

To find the length of the square's diagonal, we essentially need to calculate c, the longest side of the triangles. We can do this by plugging 6 into the equation as a and b.

[tex]a^2+b^2=c^2\\6^2+6^2=c^2\\36+36=c^2\\72=c^2\\\sqrt{72} =c[/tex]

[tex]8.5[/tex] ≈ [tex]c[/tex]

Therefore, it will be approximately 8.5cm from one corner of the square to the opposite corner.

I hope this helps!

Answer:

[tex]a(t) =n(0.25t^2)[/tex]

Step-by-step explanation:

Given

[tex]r(t) = 0.5t[/tex]

[tex]a(r) = nr^2[/tex]

Required

Determine the area in terms of time

From the question, we have:

[tex]r(t) = 0.5t[/tex] -> radius per time

and

[tex]a(r) = nr^2[/tex] --> area from radius

The interpretation of the question is to find the composite function: a(t)

If [tex]a(r) = nr^2[/tex], and [tex]r(t) = 0.5t[/tex], the

Substitute 0.5t for r

[tex]a(t) =n(0.5t)^2[/tex]

[tex]a(t) =n*0.25t^2[/tex]

[tex]a(t) =n(0.25t^2)[/tex]

Answer:

Solution in photo

Step-by-step explanation:

Answer:

a) 0.24

b) 0.3

Step-by-step explanation:

Given the following probability

P(A) = 0.4 P(B) = 0.6

a) P(A and B) =P(A)P(B) {Independent)

P(A and B) = 0.4×0.6

P(A and B) = 0.24

b) Given P(A | B) = 0.5, this is a conditional probability

If P(A | B) = P(A and B)/P(B)

Since If P(A | B) = 0.5

0.5 = P(A and B)/P(B)

P(A and B) = 0.5(P(B)

P(A and B) = 0.5(0.6)

P(A and B) = 0.3

Answer:

y =1, 1.5, 2, 2.5, 3

Step-by-step explanation:

Plug in the values of x into the equation for y.

For example when x is 0, plug in 0 into the equation

0.5x + 1 = y

0.5(0) + 1 = 1

So, y = 1

To find the other values of y, plug in the designated value of x into the equation.

Answer:

HI

Step-by-step explanation:

In a triangle, the length size of each side corresponds to the size of the degree of the angle opposite it.

This means, the biggest angle would be opposite the side with the longest length, while the angle with the least degree will be opposite the side that is the smallest.

In ∆HIJ, the least angle measure is <J (54°).

Side length opposite to <J is HI.

Therefore the smallest side of ∆HIJ is HI

Answer:

4(20+3)

Step-by-step explanation:

4(2+13) = 4(15)

4(20+30) = 4(50)

4(2+3) = 4(5)

4(20+3) = 4(23)

Therefore, 4(20+3) is the answer since it's equivalent to 4(23).

Answer:

Step-by-step explanation:

[tex]We\ are\ given:\\Dimensions\ of\ the\ door=2m *1m\\Dimensions\ of\ the\ wall=8.5m*2m\\Cost\ of\ whitewashing\ of\ 1m^2=40\ rupees\\Hence,\\First\ lets\ consider\ the\ wall:\\Area\ of\ a\ rectangle= Length*Width\\Here,\\Length\ of\ the\ wall=8.5\ m\\Width\ of\ the\ wall=2\ m[As\ here\ width\ and\ height\ are\ the\ same\ thing]\\Hence,\\Area\ of\ the\ wall=8.5*2=17\ m^2[/tex]

Answer:

3x³ - 18x² + 26x - 8

Step-by-step explanation:

(x - 4)(3x²- 6x + 2) =

= x*3x² + x*(- 6x) + x*2 + (-4)*3x² + (-4)*(-6x) + (-4)*2

= 3x³ - 6x² + 2x - 12x² + 24x - 8

= 3x³ - 18x² + 26x - 8
