For this question we just need to use a simple rule of three as follows:

As we can see above, the rule of three solves the question "if we have 150mg for 1ml so how much do we have for 30 mg". So the final answer is 0.2 ml.

The total amount (in dollars) saved using both plans combined is T = 50 + 101.1N.

Based on the information, the function = 50+20.55N.

where N is the number of weeks she has been saving.

For the second function, this is illustrated as:

function B = 80.55 N.

Therefore, the total of the plans combined will be:

T = 50 + 20.55N + 80.55N

T = 50 + 101.1N

About Percentage

The Latin adverb "percent" means "by the hundred." The 16th century saw its invention. The abbreviation was later changed to %. Later, the period was eliminated, and the two words were merged to form the term "percent." Brief explanations employ the annotation sign %. Calculate your percentage of marks by comparing your final score to your overall score.

The percentage is a fraction or a ratio in which the value of the whole is always 100. For example, if Sam scored 30% marks in his math test, it means that he scored 30 marks out of 100. It is written as 30/100 in the fraction form and 30:100 in terms of ratio.

Percentage  Definition:

The percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Answer:

66.667%

Step-by-step explanation:

In a fair die, there are 6 possible rolls. Out of the 6, 1 number is chosen each time. Since orde does not matter in this problem, we will be applying combination, so this would be written as 6C1 x 4. In order to exclude 3 and 4, from 6, the choices must be narrowed down to 4. Written out as an equation, this would be 4C1 x 4. To get the percentage, simply divide the two equations.

(4C1 x 4)/(6C1 x 4) = 0.66667 = 66.667%

Step-by-step explanation:

The percent tip which Ai mi added to the $9 dinner as required in the task content is; 31%.

It follows from the task content that the percent tip which Ai mi added to the dinner is to be determined by evaluation.

Since the dinner itself costs; $9 and she paid $11.79 after adding tip, it follows that the percent tip is the percentage change in price paid per unit original price as follows;

Percent tip = { ( 11.79 - 9 ) / 9} × 100%

Percent tip = 2.79/9 × 100%

Percent tip = 31%.

Okay, here we have this;

Considering the provided graph, we are going to calculate the requested height, so we obtain the following:

So to calculate the height of the trapezoid, we will replace in the area formula with the given information, so we have:

A=(b1+b2)h/2

10 ft²=(7ft+3ft)h/2

10 ft²*2=(10 ft)h

20 ft²=(10 ft)h

h=20 ft²/10 ft

h=2 ft

Finally we obtain that the height of the ramp is 2ft, then the correct answer is the second option.

we have the following

sin of an angle is the same as:

therefore we can create the following right triangle:

we can calculate the adjacent side using the pythagorean theorem

where h is the hypotenuse, a is the adjacent side and b the opposite side to the angle.

thus, the adjacent side is:

Using that value, we can now calculate cos of the angle

which can't be simplify, thus that is the answer for the exact value

Given that:

- The triangle is isosceles.

- Its base is 49.96 meters.

The situation describes an exponential growth, which can be expressed using the general formula:

Where

a is the initial value

r is the growth rate, expressed as a decimal value

x is the number of times intervals

y is the final value after x time intervals

For the studied population, the growth rate is 2.5%, to express this number as a decimal value you have to divide it by 100:

The initial value is the current population of the town: a=50000

You can express the equation of exponential growth for this population as follows:

We know that after x years the population will be y=100000, to determine how many years it will take to reach this value you have to equal the equation to 100000 and solve for x:

-Divide both sides of the expression by 50000

-Apply logarithm to both sides of the equal sign:

-Divide both sides by the logarithm of 1.025

After approximately 28 years the population of the town will be 100,000.

Using it's concept, the probabilities are given as follows:

1. Red then white: 7/26.
