Area of the cross-section of the first story is:

Area of the cross-section of the second story is the sum of rectangular and triangular sections:

Since both story's have same cross-section area, we have equation:

The height of the second story is 13 inches.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, the first story has length=30 inches and width=8 inches.

Now, area of the cross-section of the first story is

A = Length×Width

A = 30×8

A = 240 square inches

Area of the cross-section of the second story is the sum of rectangular and triangular sections:

A = Length×Width + 1/2×Base×Height

A = 30×3 + 1/2×30×(h - 3)

A = 90 + 15(h - 3)

A = 90 + 15h - 45

A = 15h + 45

Since both story's have same cross-section area, we have equation:

15h + 45 = 240

15h = 195

h = 195/15

h = 13 inches

Therefore, the height of the second story is 13 inches.

Answer:

The equation to represent the given statement is:

(7/2) + (4 * x) < 1

We can simplify the equation as follows:

(7/2) = 3.5

And then:

3.5 + (4 * x) < 1

Finally:

3.5 - 1 < - (4 * x)

2.5 < - (4 * x)

Dividing both sides by -4:

-2.5/4 > x

-0.625 > x

Step-by-step explanation:

This means that for the equation to be true, the value of x must be less than -0.625.

The banner should be 56 feet long to fit the garage door.

The perimeter of a rectangle is the total length of all the sides of the rectangle.

P = 2 (L + B)

P = perimeter of rectangle, L = Length of rectangle, B = Breadth of rectangle

Given length of garage door = 12 feet

Given breadth of garage door = 16 feet

P = 2 (L + B)

P = 2 ( 12 + 16)

P = 2 (28)

P = 56 feet

Hence, The total length of the banner should be 56 feet to cover the entire door.

1 pound = 0.455 kilograms

We know that one kilogram is 2.2 pounds, and we want find what is the "kilogram per pound".

We can write the relation:

1 kilogram = 2.2 pounds

To get the "kilogram per pound" we need to have a "1" on the right side, so we can divide both sides by 2.2, then we will get:

(1 kg)/2.2 = (2.2 lb)/2.2

0.455 kg = 1lb

Using Pythagoras theorem, The missing side of the right triangle is 4,9 mm long.

Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle. The hypotenuse in this example is the longest side because it is located across from the 90° angle. A right triangle's positive integer sides (let's say sides a, b, and c) are squared to produce a Pythagorean triple equation.

Right triangles are what the provided triangle is.

The Pythagorean Theorem is used:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex](5)^{2} + (7)^{2} = c^{2}[/tex]

25 + 49 =[tex]c^{2}[/tex]

The 3.13%  interest rate will cause his money to double in approximately 23 years.

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

Given that Arnulfo deposited $55 into a savings account for which interest is compounded semiannually.

According to the rule of 72, we should divide 72 by the interest rate to determine how many years it will take to double our money at a specific interest rate (r).

time is taken to double the money = 72/r,

where r represents the interest rate and time is in years.

As we have been given that it will take approximately 23 years to double Arnulfo's money, so we can set an equation as:

23 = 72/r

r = 72/23

r = 3.13

Hence the interest rate is 3.13%.

The capacity of the two containers can be measured with a jar with a maximum capacity of 20 litres.

In this problem we find the case of two containers with different capacity, one with a capacity of 40 litres and other with a capacity of 60 litres, we can measure each of them based on the number of adds needed to fill each container. The number of adds (n) is equal to the container capacity (C), in litres, divided by the jar capacity (c), in litres:

n = C / c

If we assume that the number of adds is a natural numbers, then we determine the greatest common factor of both container capacities. First, decompose each number related to each container:

40 = 2³ × 5

60 = 2² × 3 × 5

Second, find the common factors and create the resulting product:

G.C.F. = 2² × 5

G.C.F. = 20

A jar with a maximum capacity of 20 litres can be used to measure the capacity of both containers.

The exact surface area of the cone is 113.097 units².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Base of a cone is circle.

Base area = π r²

                 = π (4)² = 16π

Lateral surface area = π r √(h² + r²)

                                  = 4π √(3² + 4²)

                                  = 4π √25

                                  = 4π × 5

                                  = 20π

Total surface area = 16π + 20π

The speed of a car is 0.61 kilometer per hour.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

From the figure, time =1.68 minutes and distance =17 meter

Now, in kilometer per hour is

Here, speed = Distance/Time

= 17 meter/1.68 minute

= 0.017 km/0.028 hours

= 0.017/0.028

The probabilities are equal, the expected time until the buzzer goes off simplifies to E(X) = 40.5.

Let X be a random variable representing the time until the buzzer goes off. X follows a uniform distribution, since any time between 20 and 60 seconds is equally likely. This can be represented by the formula P(X=x) = 1/41, where 41 is the total number of possible times (41 = 60 - 20 + 1).

Using this formula, the probability of the buzzer going off at any particular time can be calculated. For example, the probability of the buzzer going off at 23 seconds is P(X=23) = 1/41. The expected time until the buzzer goes off can also be found by taking the sum of each possible time multiplied by its individual probability. This is calculated as E(X) = Σ(x*P(X=x)). Since all the probabilities are equal, the expected time until the buzzer goes off simplifies to E(X) = 40.5.
