The number 8.75 is equivalent to the fraction 35/4 in its simplest form.

To convert 8.75 to a fraction, we can write it as a fraction with a denominator of 1. We then multiply both the numerator and denominator by 100 to get rid of the decimal point. This gives us:

8.75 = 8.75/1

= 875/100

Next, we want to get rid of the decimal point, which we can do by multiplying both the numerator and denominator by a power of 10 that moves the decimal point of the numerator to the right until it disappears. In this case, we can multiply both the numerator and denominator by 100, which gives us:

8.75/1 x 100/100 = 875/100

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 25. This gives us:

875/100 = (875/25) / (100/25) = 35/4

Therefore, we conclude that 8.75 is equivalent to the fraction 35/4 in its simplest form.

Volume of cone =  100.48 cubic units.     and  The Volume of cylinder= 301.44 cubic units.

One of the fundamental three-dimensional forms in geometry is the cylinder, which has two distant, parallel circular bases. At a certain distance from the centre, a curved surface connects the two circular bases. The axis of the cylinder is the line segment connecting the centres of two circular bases. The distance between the two circular bases is used to define the cylinder's height. An LPG gas cylinder is one of the genuine examples of a cylinder. The cylinder is a three-dimensional object with two essential properties: surface area and volume. The whole surface area of the cylinder is composed of the combined curved surface area of the cylinder plus the areas of the two circular bases.

A cone has a radius of 4 units and a height of 6 units.

In discrete mathematics, a truth table is a table that lists all possible combinations of truth values for a given set of logical variables and shows the resulting truth values of a compound proposition.

In discrete mathematics, a truth table is a table that lists all possible combinations of truth values (usually either true or false) for a given set of logical variables and shows the resulting truth values of a compound proposition (a logical expression formed by combining the variables using logical operators such as AND, OR, and NOT). Each row of the truth table represents one possible combination of truth values, and the columns represent the variables and the various intermediate steps of the logical calculation. Truth tables are often used to determine the truth values of complex propositions and to test the validity of logical arguments.

Answer:

27) #3 --> 12x - 24 = 60

29) 2x^2 + x - 15

Step-by-step explanation:

27) If x represents the number of boxes, and there are 12 cookies in each box, multiplying 12 by x results in the total number of cookies Kendal bought. However, she kept 2 boxes for herself, which is the same as 2(12) = 24 cookies. Kendal ended up with 60 cookies at the party, so subtracting 24 cookies from the total number of cookies (12x) equals 60 cookies.

29) (3 + x)(2x - 5)

3 * 2x = 6x

3(-5) = -15

x * 2x = 2x^2

x(-5) = -5x

6x - 15 + 2x^2 - 5x =

2x^2 + x - 15

Answer: 39

Step-by-step explanation: 20 + 12+7

The population after 5 years will be approximately 8.45 billion.

The exponential equation to model the world population (in billions) after t years is P(t) = 8(1.011)^t, where P(t) is the population in billions and t is the number of years after 2022.

To write this equation, we need to use the information provided in the question. The initial population in 2022 is 8 billion, so this is our starting value. The growth rate is 1.1% per year, which can be written as 1.011 in decimal form.

We can use the formula for exponential growth, P(t) = P0(1 + r)^t, where P0 is the initial population, r is the growth rate, and t is the number of years.

Substituting the values for P0 and r into the equation, we get:

P(t) = 8(1.011)^t

This equation can be used to find the population after t years.

For example, to find the population after 5 years, we can substitute t = 5 into the equation and get:

P(5) = 8(1.011)^5 ≈ 8.45 billion

Therefore, the population after 5 years will be approximately 8.45 billion.

Answer: The given expression is:

m² +........+ 1/m²

We can notice that the expression has an even number of terms, and the first and last term are perfect squares, which suggests that it might be possible to write the expression as the square of a binomial.

Let's try to write the expression in the form of (a + b)²:

(a + b)² = a² + 2ab + b²

If we set a = m and b = 1/m, we get:

(a + b)² = m² + 2(m)(1/m) + (1/m)² = m² + 2 + 1/m²

Comparing this with the given expression, we see that it is the same as the given expression with 2 added to it.

Therefore, to make the given expression a perfect square, we need to add 2 to it.

So, the term to be inserted is 2.

The expression m² +........+ 1/m² can be written as (m + 1/m)² - 2.

Step-by-step explanation:

The speed of the boat in still water is 20.625 km/hr. and the speed of the current is 66 km/hr.

The speed formula is speed = distance / time.

Consider x= speed of current and y = speed of still water

The speed of the boat in still water can be calculated by dividing the total distance traveled by the total time taken;

(165 km x 2 = 330 km)

(5 hours + 11 hours = 16 hours).

Therefore, the speed of the boat in still water

330 km/16 hours = 20.625 km/hr.

The speed of the current can be calculated by dividing the total distance traveled by the total time taken for the downstream trip ;

(165 km x 2 = 330 km)

(5 hours).

Therefore, the speed of the current = 330 km/5 hours = 66 km/hr.

speed of still water = 20.625 km/hr.
