The volume of the larger tent in the shape of hemispheres, with circular floors, is 89.8 cubic feet.

If the diameter of the smaller tent is 6 feet, then its radius is 3 feet. Solving for the area of its circular floor,

A = πr^2

A = π(3 feet)^2

A = 9π square feet

Using the ratio of the floor areas of the two tents, calculate the area of the circular floor of the larger tent.

9 : 12.25 = 9π square feet : x

where x = area of the circular floor of the larger tent

9x = 12.25(9π)

x = 12.25 π square feet

If the area of the circular floor of the larger tent is 12.25 π square feet, then solving for its radius,

A = πr^2

12.25 π square feet = πr^2

r = 3.5 feet

Hemisphere refers to half of a sphere and its volume is given by the formula V = 2/3πr^3, where r is the radius.

V = 2/3πr^3

V = 2/3 π (3.5 feet)^3

V = 89.79719002 cubic feet

By calculating speed of each person we can find who is faster.

Speed can be defined as the distance covered with respect to time. It is a scalar quantity. It is calculated as follows

Speed  = Distance / Time taken

The time taken by each person is 20 seconds.

Distance covered by Jan = 50 meter

Speed of Jan = Distance / Time taken

Speed of Jan = 50 / 20

Speed of Jan = 2.5 meters per second

Distance covered by Dingh = 60 meter

Speed of Dingh = Distance / Time taken

Speed of Dingh = 60 / 20

Speed of Dingh = 3 meters per second

Since the speed of Dingh is more than Jan, we can say that Dingh is faster.

Distance = Speed × Time taken

Here, time taken = 1 second

This implies Distance Covered = Speed

Therefore, Jan covers 2.5 meters in one second while Dingh covers 3 meters in one second.

In 8 months he will have a total of 44 books in his collection.

The correct answer is an option (H)

In this question,

Paul collects comic books. He has 20 books in his collection, and he adds 3 per month.

We need to find the number of months required to have a total of 44 books in his collection.

Let n be the required number of months.

From given information, we get an equation,

20 + 3n = 44

We solve above equation to find the required number of months.

20 + 3n - 20 = 44 - 20

3n = 24

n = 8

Therefore, in 8 months he will have a total of 44 books in his collection.

You remove the difference between the two numbers from each other. E.g., 5-2=3, and 6-4=2.

Step-by-step explanation:

An isosceles triangle is one with two equal-length sides. ΔABC is an isosceles triangle.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²] units.

Given that the coordinates of the vertices of the triangle are A(0,0), B(a, b), and C(2a, 0). Now, to prove that the given triangle is an isosceles triangle we need to find the length of each side of the triangle.

AB = √[(x₂-x₁)² + (y₂-y₁)²]

     = √[(a - 0)² + (b - 0)²]

     = √(a² + b²)

BC = √[(x₂-x₁)² + (y₂-y₁)²]

     = √[(2a - a)² + (0 - b)²]

     = √(a² + b²)

AC = √[(x₂-x₁)² + (y₂-y₁)²]

     = √[(2a - 0)² + (0 - 0)²]

     = √4a²

     = 2a

Since the length AB and BC are the same, while the length of AC is different, therefore, ΔABC is an isosceles triangle.

A B =7 inches, A C = 32 inches, and point B is between points A and C.

We have to find the length of BC in inches.

What are Collinear points?

If two or more points are lie on a straight line then points are called Collinear points.

Now,

Line l contains points A, B and C.

Point B is between points A and C.

Length of A B = 7 inches and A C = 32 inches

The equation of the circle that passes through the point (-2 , 3) and has a center at the origin is x^2 + y^2 = 13.

Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-2 , 3).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(-2 - 0)^2 + (3 - 0)^2

radius= √4 + 9

radius = √13

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (0 , 0)

r = √13

(x - 0)^2 + (y - 0)^2 = (√13)^2
