Answer: the area of the shape=25.5 cm²

Step-by-step explanation:

This shape  is composed of a rectangle and a trapezoid

The area of the rectangle= 3(4)

The area of the rectangle= 12 cm²

\(\displaystyle\\The\ area\ of\ the\ trapezoid=\frac{3+6}{2} (7-4)\\\\The\ area\ of\ the\ trapezoid=\frac{9}{2} (3)\\\\The\ area\ of\ the\ trapezoid=4.5(3)\\\\The\ area\ of\ the\ trapezoid=13.5 \ cm^2\)

The area of the shape=12+13.5

The value of y when x is 9 and the constant of proportionality(k) is 4 is 36.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, x and y vary directly and y is 44 when x is 11.

Let, y ∝ x.

y = kx.

44 = 11k.

k = 44/11.

k = 4.

Now x = 9.

y = 4×9.

y = 36.

Answer:

The volume of the cylinder is 81π cubic meters.

The volume of a cylinder

Volume = π × radius² × height

The diameter of the cylinder is 6m, we can determine the radius by dividing the diameter by 2

Radius = diameter / 2 = 6m / 2 = 3m

Since the height is triple the radius

Height = 3 × radius = 3 × 3m = 9m

Now we can substitute these values into the volume formula

Volume = π × (3m)² × 9m

Volume = π × 9m² × 9m

Volume = 81π m³

Therefore, the volume of the cylinder is 81π cubic meters.

The percentage of students who got a final grade higher than a specific value cannot be determined without knowing the value.

To determine the percentage of students who got a final grade higher than a specific value, we need to know the actual value. Without this information, we cannot calculate the percentage accurately.

For example, if we have the grades of 100 students and we want to know the percentage of students who scored higher than 80, we would need to count the number of students who scored higher than 80 and divide it by 100 (the total number of students) to get the percentage.

Without specifying the specific value or providing the necessary data, it is not possible to calculate the percentage of students who got a final grade higher than a certain value.

Sara that used 1/5 of her money and had a remainder of $40 at first has $200 of money

Is a number that expresses the portion of some number over a total. The number that expresses the portion is known as the numerator and the number that expresses the total is known as the denominator.

Lets call the total amount of money = x

As she used the 1/5 of the money and had 40$ of remainder, we have:

x*1/5 = 40

Isolating the variable:

x*1 = 40*5

x = (40*5)/1

x = 200

200 * 1/5 = 40

40 = 40

A system of equations that model the situation are e = a - 12 and a + e = 100.

The number of tickets Alberto won is 56 tickets.

The number of tickets Elian won is 44 tickets.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of tickets Alberto won and number of tickets Elian won, and then translate the word problem into an algebraic equation as follows:

Since Alberto won 12 tickets less than Elian, a linear equation that models this situation is given by:

e = a - 12     .....equation 1.

Additionally, when they put their tickets together they have exactly 100 tickets;

a + e = 100     .....equation 2.

By solving the system of linear equations simultaneously, we have:

a + a - 12 = 100

2a = 112

a = 112/2

a = 56 tickets.

For the number of tickets (e) Elian won, we have:

e = a - 12

e = 56 - 12

e = 44 tickets.

Step-by-step explanation:

Answer:

  585 m

Step-by-step explanation:

You want to know the length of a field if the angle of depression from a point 1200 m above one end is 64° to the other end.

The tangent relation is ...

  Tan = Opposite/Adjacent

In this problem, the height of the plane is the side opposite the angle of interest, and the adjacent side is the length of the field. Solving for the adjacent side, we get ...

  length of field = (height of aeroplane) / tan(64°)

  length of field = (1200 m)/2.05030 ≈ 585.28 m

The field is about 585 meters long.

Step-by-step explanation:

The answers, rounded to the appropriate number of significant figures, are as follows:

(a) 1.088 ×\(10^2\)

(b) 2.132

(c) 1.3331 ×\(10^1\) and

(d) 1.05.

Let's calculate the answers to the given operations using the appropriate number of significant figures.

(a) 8.370×1.3×10

To perform this multiplication, we multiply the decimal numbers and add the exponents of 10:

8.370 × 1.3 × 10 = 10.881 × 10 = 1.0881 × \(10^2\)

Since the original numbers have four significant figures, we round the final answer to four significant figures:

1.088 × \(10^2\)

(b) 4.265/2.0

For division, we divide the decimal numbers:

4.265 ÷ 2.0 = 2.1325

Since both numbers have four significant figures, the answer should be rounded to four significant figures:

2.132

(c) (1.2588×\(10^3\))×(1.06×\(10^-^2\))

To multiply these numbers, we multiply the decimal numbers and add the exponents:

(1.2588 × \(10^3\)) × (1.06 × \(10^-^2\)) = 1.333128 × \(10^1\)

Since the original numbers have five significant figures, we round the final answer to five significant figures:

1.3331 × \(10^1\)

(d) \((1.11)^(^1^/^2^)\)

To calculate the square root, we raise the number to the power of 1/2:

\((1.11)^(^1^/^2^)\)= 1.0524

Since the original number has three significant figures, the answer should be rounded to three significant figures:

1.05

It's important to note that the significant figures in a result are determined by the original data and the operations performed. The final answers provided above reflect the appropriate number of significant figures based on the given information and the rules for significant figures.
