Using fractions, we can determine that the enrolment percentage in relation to the Spanish class is 72%.

A fraction is a component of a whole.

Mathematically, the number is expressed as a quotient, where the numerator and denominator are divided.

In a simple fraction, both are integers.

In a complex fraction, a fraction can be found in either the numerator or the denominator.

A suitable fraction has a numerator that is less than its denominator.

So, let's say that x students are enrolled in the Spanish class.

The enrolment in the French class is 0.72 times as large as the attendance in the Spanish class, or 0.72, according to the figures provided.

The enrollment as a percentage of Spanish classes is:

0.72x / x = 0.72

The enrolment percentage in relation to the Spanish class is:

0.72 x 100% = 72%

Therefore, sing fractions, we can determine that the enrolment percentage in relation to the Spanish class is 72%.

Answer: 52.8 m

Step-by-step explanation:

What you want to try to do when you come across these shapes is to think about it as two different shapes instead of one. The bigger rectangle should have a perimeter of 31 (12.3+12.3+3.2+3.2). Now for the bottom rectangle, you have to solve for one of the side lengths. Subtract 3.2 from 8.6 (as 3.2 is already being used by the top rectangle's perimeter) to get 5.4. The perimeter of the smaller rectangle should be 21.8 (5.5+5.5+5.4+5.4). Now add 31+21.8 to get 52.8 and that should be the total perimeter of your shape. :)

The volume of the cylindrical water tank can be calculated as:

Volume = π x radius^2 x height

We know that the tank holds 1,200 liquid gallons, which is equivalent to:

1,200 / 7.48 = 160.43 cubic feet

We also know that the radius of the tank is 2.4 feet. Substituting these values into the formula, we get:

160.43 = 3.14 x 2.4^2 x height

Solving for height, we get:

height = 160.43 / (3.14 x 2.4^2) = 8.9 feet (approx.)

Therefore, the approximate height of the water tank is 8.9 feet (b).

Sequence from least interest amount to greatest amount is

investment of $400 at 3% for 6 years

investment of $400 at 14% for 2 years

investment of $300 at 14% for 6 years

Simple interest is a type of interest that is calculated only on the principal amount of a loan or investment, without taking into account any accumulated interest from previous periods. It is a linear function of time and is calculated by multiplying the principal amount, the interest rate, and the time period. The formula for simple interest is:

I = P × r × t

To calculate the simple interest earned on an investment of $400 at 3% for 6 years, we can use the formula:

I = P × r × t

Plugging in the given values, we get:

I = 400 × 0.03× 6

I = 72

Therefore, the simple interest earned on an investment of $400 at 3% for 6 years is $72.

To calculate the simple interest earned on an investment of $300 at 14% for 6 years, we can use the formula:

I = P ×r× t

Plugging in the given values, we get:

I = 300×0.14× 6

I = 252

Therefore, the simple interest earned on an investment of $300 at 14% for 6 years is $252.

To calculate the simple interest earned on an investment of $400 at 14% for 2 years, we can use the formula:

I = P ×r ×t

Plugging in the given values, we get:

I = 400 ×0.14 × 2

I = 112

Therefore, the simple interest earned on an investment of $400 at 14% for 2 years is $112.

Hence, sequence from least interest amount to greatest amount is

investment of $400 at 3% for 6 years

investment of $400 at 14% for 2 years

investment of $300 at 14% for 6 years

To find the value canceled in the second installment, we need to determine the total amount owed at the beginning of the ninth month, and then subtract the first installment paid in the third month.

Let's start by finding the total amount owed at the beginning of the ninth month, using the given financing conditions.

The initial fee of $500,000 is not subject to financing, so we can exclude it from our calculations.

The amount financed is the remaining balance, which is:

$5,000,000 - $500,000 = $4,500,000

The financing rate is 26% capitalizable quarterly, which means that each quarter, the amount owed increases by 26% of the previous balance.

Since there are two quarters between month 3 and month 9, the amount owed at the beginning of month 9 is:

$4,500,000 × (1 + 0.26/4)^2 = $5,279,322.14

Next, we subtract the first installment of $1,000,000 paid in the third month:

$5,279,322.14 - $1,000,000 = $4,279,322.14

Let x be the number of kilograms of apples in the fruit salad.

Then, the number of kilograms of oranges is (2/3)x, because the ratio of apples to oranges is 3:2.

The total weight of fruit salad is 3 kgs, so we can write an equation:

x + (2/3)x = 3

Simplifying and solving for x, we get:

(5/3)x = 3

x = (3*3)/5

x = 1.8

Therefore, there are 1.8 kg of apples and (2/3)*1.8 =

To find on what interval the temperature is positive, we need to find the values of x for which f(x) is greater than zero.

The function f(x) is defined as:

f(x) = -3|x - 4.7| + 2

Since the absolute value of any real number is always non-negative, we can see that f(x) will be positive only if the expression inside the absolute value bars is less than 2/3. So, we can set:

-3|x - 4.7| + 2 > 0

Solving for |x - 4.7|, we get:

|x - 4.7| < 2/3

This means that x must be within 2/3 units of 4.7. So, the interval on which the temperature is positive is:

4.7 - 2/3 < x < 4.7 + 2/3

Simplifying, we get:

4.0333 < x < 5.3667

Therefore, the temperature is positive on the interval (4.0333, 5.3667).

We have found that: AB = (BD/2) * (XZ/AY) and we can solve for BD:

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

Since BD is a median of triangle ABC, it divides side AC into two equal parts. Let's label the midpoint of AC as M. Similarly, YW is a median of triangle XYZ and it divides side XZ into two equal parts, with the midpoint labeled as N.

Since AABC~AXYZ, we know that the corresponding sides are proportional. Thus,

AB/AX = AC/AY = BC/BZ

Since AB = BC (given that B is a vertex of both triangles), we have:

AB/AX = AC/AY

We can rewrite this equation as:

AB/AC = AX/AY ----(1)

Since BD is a median of triangle ABC, we have:

BD = 1/2 AC ----(2)

Similarly, since YW is a median of triangle XYZ, we have:

YW = 1/2 XZ ----(3)

From equation (1), we have:

AB/AC = AX/AY

Multiplying both sides by AC, we get:

AB = AX * (AC/AY)

Now, using equation (2), we can substitute AC/2 for BD:

AB = AX * BD/AY

Finally, using equation (3), we can substitute XZ/2 for YW:

AB = (BD/2) * (XZ/AY)

Therefore, we have found that:

AB = (BD/2) * (XZ/AY)

Hence, we can solve for BD:

BD = 2 * AB * AY / XZ

Note that we need to know the actual values of AB, AY, and XZ to find BD.

The area of the shaded region of the composite figure is 389 square units.

A geometric shape made up of two or more simpler shapes is known as a composite figure. You must divide a composite figure into simpler shapes and then add up each shape's unique regions to determine the composite figure's area.

The methods you can take to determine a composite figure's area are as follows: Slice up the composite figure into more basic forms. You can separate the composite figure into its component parts, for instance, if it is made up of a rectangle and a triangle.

Calculate the area of each shape separately.

The total area of the composite figure can be calculated by adding the areas of all the simpler shapes.

The shaded region can be divided into a rectangle and a triangle.

The area of the rectangle with l = 19 and w = 17 is:

Area = length x width = 17 x 19 = 323 square units

Now, the dimensions of the triangle are:

base = 17 - 6 = 11

height = 31 - 19 = 12

Thus,

Area = (base x height) / 2 = (11 x 12) / 2 = 66 square units

Now, the total area of the shaded portion is:

Area = 323 + 66 = 389 square units.

Therefore, Blanche's balance from Account 1 over 4.8 years would be approximately $10,081.25.

To find the annual amount, you first need to know the frequency of the payment. If the payment is made monthly, you need to multiply the monthly payment by 12 to get the annual amount. If the payment is made weekly, you need to multiply the weekly payment by 52 (the number of weeks in a year) to get the annual amount.

If the payment is irregular or occurs at different intervals, you can add up the total amount received over the course of the year and use that as the annual amount.

by the question.

To calculate the balance of Account 1 after 4.8 years, we can use the formula for compound interest:
