The area of the shape is given as 24.52 cm2

We have two triangles and 1 rectangle

we have to find the area of the triangles first and then solve for the area of the rectangle.

The area of a triangle = 1/2bh

for first triangle

area = 1/2 * 2.7 * 3

= 4.05

for second triangle

height = 6.8 - 2.7

= 4.1

area = 1/2 * 3.4 * 4.1

= 6.97

For the rectangle

area = l * w

= 2.7 * 5 = 13.5

The area = 13. 5 + 6.97 + 4.05

= 24.52 cm2

7/8 - 2/8 = 5/8

George ate 5/8 more than Grace.

The perimeter of the figure is 68+24=92 cm.

The area of Rectangle is length times of width.

In the given figure there is a rectangle and right angle triangle.

The length of rectangle is 16 cm and width is 18 cm

Perimeter=2(length+Breadth)

=2(16+18)

=68 cm

Now let us find perimeter of triangle

Base of height is 6cm and base is 8

P=a+b+√a²+b²

=6+8+√6²+8²

=24

Hence, the perimeter of the figure is 68+24=92 cm.

Generally, A logarithm is a mathematical function that determines the power to which a given number (called the base) must be raised to obtain a certain value. In other words, a logarithm is the inverse operation of exponentiation.

For example, if we take the base 2 and the value 8, the logarithm of 8 to the base 2 (written as log2 8) is 3, because 2 raised to the power of 3 (i.e., 2^3) equals 8.

Logarithms are widely used in many fields of science, engineering, and mathematics, particularly in areas where large numbers or very small numbers are involved. They are also used in data analysis, signal processing, and many other applications.

Answer: A: Yes. The input and output are both feasible.

Step-by-step explanation:

To determine whether the solution (29.5, $212.50) makes sense for the function c(x), we need to evaluate whether the input and output are feasible and make sense in the context of the problem.

The input is given as 29.5, which represents the number of students. It is unclear from the information given whether a non-integer value for the number of students is feasible or not. However, if we assume that 29.5 students means 29 students and 1 child attending the carnival, then the input of 29.5 students is feasible.

The output is given as $212.50, which represents the amount of money spent at the carnival. It is reasonable to assume that a school group on a field trip would spend a certain amount of money at a carnival, and $212.50 is not an unreasonable amount to spend.

Therefore, based on the information given, we can conclude that the solution (29.5, $212.50) makes sense for the function c(x). So the answer is A: Yes. The input and output are both feasible.

The Fundamental Counting Principle, choosing from 3 sizes of bottled water and from distilled, filtered, or spring water is 9 ways.

The Basic Counting Principle is a technique used in mathematics, more especially in probability theory and combinatorics, to determine how many combinations of options, items, or outcomes are possible. The Rule of Multiplication, the Product Rule, the Multiplication Rule, and the Basic Counting Rule are some of its alternate names.

It has a connection to the Sum Rule, often known as the Rule of Sum, which is a fundamental counting method used to calculate probabilities.

According to the Basic Counting Principle, if a decision or event has a potential result or set of options, and a different decision or event has b possible outcomes or choices, then the sum of all the unique combinations of outcomes for the two is ab.

Using the fundamental counting principle, if an event occurs in m ways and another event occurs in n ways then the total occurrence is given as (m)(n).

Given that,

m = 3 for choosing between sizes.

n = 3 for distilled, filtered, or spring water.

Thus, the total number of occurrence is given as:

T = (3) (3) = 9

Hence, the Fundamental Counting Principle, choosing from 3 sizes of bottled water and from distilled, filtered, or spring water is 9 ways.

The required population of the city is approximately 44,44.44.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Let's use algebra to solve for the population of the city.

Let P be the population of the city. We know that 27% of the population is from 50 to 64 years old.

The number of people from 50 to 64 years old is 27% of the whole population, which can be expressed as,

0.27P

We can set up an equation to relate the number of people from 50 to 64 years old to the number of eligible voters,

0.27P = x

where x is the number of people from 50 to 64 years old who voted.

We can solve for P by multiplying both sides of the equation by the reciprocal of 0.27,

P = x / 0.27

Substituting x with 1200,

P = 12,00 / 0.27 = 4444.44

Therefore, the population of the city is approximately 44,44.44.

The total surface area of the cylinder is S = 45π units²

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the surface area of the cylinder be represented as S

where x is the amount of money Hong would make for 13 hours of work.

To solve for x, we can cross-multiply and simplify:

Therefore, at the same rate, Hong would make 234 dollars for 13 hours of work.

The constant 0.9965 is the rate of change per hour. Specifically, it represents the factor by which the quantity changes every hour. In this case, the factor is less than 1, indicating that the quantity is decreasing over time.

To see how this rate of change works, consider an example:

If the initial quantity is 930, after one hour the quantity will be:

f(1) = 930(0.9965) ≈ 926.20

That is, the quantity has decreased by a factor of 0.9965, or about 0.35%.

After two hours, the quantity will be:

f(2) = 930(0.9965)^2 ≈ 922.42

That is, the quantity has decreased by a factor of 0.9965 twice, or about 0.70%.

So the constant 0.9965 reveals the rate of change of the quantity, which is a decrease of about 0.35% per hour.
