What is the conversion of 6,25% as a fraction?

Answer:

10 pretzels and 2 drinks

Step-by-step explanation:

2 drinks are 12

10 pretzels are 32.50

Answer:

2 drinks, 10 pretzels

Step-by-step explanation:

d = # of drinks

p = # of pretzels

1)  d + p = 12

2)  $6d + $3.25p = $44.50

solve equation 1 for d:  d = 12 - p    substitute this into equation 2 and solve for p

6(12 - p) + 3.25p = 44.50

72 - 6p + 3.25p = 44.50

-2.75p = 44.50 - 72

-2.75p = -27.50

p = -27.50/-2.75 = 10     plug this into equation 1 and solve for d

d = 12 - 10 = 2

double check the answers:  6(2) + 3.25(10) = 44.50  correct!

The conversion value of Celsius to Fahrenheit for the value 30 Celsius is equal to 86 Fahrenheit.

Relation to convert the temperature from Celsius to Fahrenheit is equal to :

°F = 9 /5 ( ° C ) + 32.

Convert 30 Celsius  to Fahrenheit by substituting the value in the formula :

= 9 /5 ( 30° ) + 32

= 9 (6° ) + 32

= 54°  + 32

= 86°F

The number of students in the van are 6 and in the bus are 35.

A system of equations is a combination of equations with a common solution pair.

Given is that the senior class at high school A rented and filled 3 vans and 7 buses with 263 students. High school B rented 12 vans and 3 buses with 177 students. every van had the same number of students in it as did the buses.

Assume that there are {x} students in each van and {y} students in each bus. We can write the system of equations as -

3x + 7y = 263

12x + 3y = 177

Now, we can write -

3x + 7y = 263

3x = 263 - 7y

4 x 3x = 4(263 - 7y)

12x = 1052 - 28y

So -

1052 - 28y + 3y = 177

25y = 1052 - 177

25y = 875

y = 35                                           ... { 1 }

and

3x + 7 x 35 = 263

3x = 18

x = 6                                            ... { 2 }

Therefore, the number of students in the van are 6 and in the bus are 35.

Let:

w = number of withdrawals

C = Monthly cost

For Bella:

$3 = Fixed monthly charge

The sum of angles of a polygon having 10 sides is equal to 1440°.

The sum of angles of a polygon having 10 sides is equal to 1440°. This can be calculated by using the formula:

Sum of angles of a polygon = (n - 2) * 180°

Where n is the number of sides of the polygon.

Therefore, substituting the value of n = 10 in the above formula, we get:

Sum of angles of a polygon = (10 - 2) * 180°

Sum of angles of a polygon = 8 * 180°

Sum of angles of a polygon = 1440°

Hence, the sum of angles of a polygon having 10 sides is equal to 1440°.

Using ratios we know that the area of the 2nd garden is 4 times larger than the area of the 1st garden.

A ratio in mathematics displays how often one number occurs in another.

For instance, if there were eight oranges and six lemons on a fruit platter, the ratio of oranges to lemons would be eight to six.

In comparison to lemons, which make up 6:8, oranges account up 8:14 of the overall fruit.

A calculator will return a result of 0.6 decimals if you enter this.

In other words, any two numbers that divide to produce the same result are equal to 3/5.

So, the area of the 1st garden:

The formula for the volume of a cylinder is:

V = πr^2h

where r is the radius of the cylinder and h is its height.

In this case, the radius is x+3 and the height is x+11, so we can substitute these values into the formula:

V = π(x+3)^2(x+11)

Simplifying this expression, we have:

V = π(x^2 + 6x + 9)(x+11)

V = π(x^3 + 17x^2 + 69x + 99)

Therefore, the volume of the cylinder with radius x+3 and height x+11 is π(x^3 + 17x^2 + 69x + 99) cubic units.

The quotient of (5+21) (6-4) and (2+1) is 13/3, expressed in its simplest form

The quotient of two numbers is a way of expressing the ratio of their values. It is the result of dividing one number by the other, and can be written as a fraction or as a decimal.

The quotient of 4 and 8 is 0.5, since 4 divided by 8 is 0.5.

The quotient of (5+21) (6-4) and (2+1) can be expressed as follows:

First, we need to solve each parenthesis separately. The first parenthesis is (5+21), which equals 26. The second parenthesis is (6-4), which equals 2. Therefore, the quotient of (5+21) (6-4) is 26/2, which can be simplified to 13/1.

The requried length of the segment CE in the given figure is 16 centimeters.

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,
From the given figure,
Applying the trig ratios in triangle ABC to evaluate BC,
tan60 = 12/BC
BC = 12/√3
BC = 4√3

Now,
BC = AD and ∠EAD = 90 - ∠ABC  [∠ABC = ∠ADC]
So ∠EAD = 90 - 60 = 30

Again in triangle ADE,
tan60 = ED/AD
ED = AD/√3
ED = 4√3/√√3
ED = 4

Therefore, the solutions to the simultaneous equation are (x, y) = ((5 + √(21))/2, (5 - √(21))/2) and (x, y) = ((5 - √(21))/2, (5 + √(21))/2).

To solve the simultaneous equation 1÷x + 1÷y = 5, 1÷y - 1÷x = 1, we can use the substitution method. Here are the steps to solve the equation:
1. Rearrange the first equation to get 1÷y = 5 - 1÷x
2. Substitute this into the second equation to get 1÷(5 - 1÷x) - 1÷x = 1
3. Multiply both sides by x(5 - 1÷x) to get x - (5 - 1÷x) = x(5 - 1÷x)
4. Simplify and rearrange to get x² - 5x + 1 = 0
5. Use the quadratic formula to solve for x: x = (-(-5) ± √((-5)² - 4(1)(1)))÷(2(1)) = (5 ± √(21))/2
6. Substitute the values of x back into the first equation to find the corresponding values of y: y = 1÷(5 - 1÷((5 + √(21))/2)) = (5 - √(21))/2 and y = 1÷(5 - 1÷((5 - √(21))/2)) = (5 + √(21))/2

Amount Luigi invests = $350,000

The ratio in which the profit was split after their first year = Within the same ratio of their initial investments

The amount of profit made by the business = $3 million

The ratio of their initial investment = 500,000 : 350,000 = 10 : 7

The bell shaped distribution is the continuous probability distribution with a specific shape resembling a symmetrical

Bell-shaped distribution is a statistical term that describes a continuous probability distribution with a specific shape resembling a symmetrical, bell-shaped curve. This distribution is also known as the normal distribution or Gaussian distribution.

The bell-shaped distribution is characterized by its mean, which is the center of the curve, and its standard deviation, which measures the spread of the distribution. The curve is symmetric, meaning that the probabilities of values to the left and right of the mean are equal.

In a bell-shaped distribution, the majority of data points cluster around the mean, with fewer points as you move further away from the mean. The tails of the distribution extend infinitely in both directions, although the probability of observing values far from the mean becomes increasingly small.

The normal distribution is used in many fields, including science, engineering, and finance, to model real-world phenomena that are influenced by many small, random factors.

Area of trapezoid, A = ½ × (a + b) × h

Where:

By substituting the given parameters, we have the following:

Area of trapezoid, A = ½ × (a + b) × h

Area of trapezoid, A = ½ × (250 + 150) × 200

Area of trapezoid, A = (400) × 100

Area of trapezoid, A = 40,000 m².

A population is a group of organisms of the same species that live in the same geographic area and are capable of interbreeding. The term "population" can refer to a group of animals, plants, bacteria, or any other type of living organism.

Populations can vary in size from just a few individuals to millions or even billions. The size of a population can be influenced by a number of factors, including birth rates, death rates, immigration, and emigration.

Populations also have characteristics that define their genetic makeup, such as the frequency of particular alleles or genes. This genetic diversity can influence the ability of a population to adapt to changes in its environment or to recover from disturbances, such as disease outbreaks or natural disasters.

Understanding population dynamics is important for fields such as ecology, conservation biology, and public health, as it can help us to better manage and protect populations of organisms, including our own.
