Answer:

There were 60 audience members at the seminar.

Step-by-step explanation:

Let's assume that the total number of audience members at the seminar is "x".

From the given information, we know that:

2/5 of the audience were students, so the number of students was (2/5)x

3/10 of the audience were retirees, so the number of retirees was (3/10)x

The rest were professionals, so the number of professionals was x - (2/5)x - (3/10)x = (1/10)x

We also know that there were 18 more students than professionals, so:

(2/5)x - (1/10)x = 18

Multiplying both sides by 10, we get:

4x - x = 180

Simplifying, we get:

3x = 180

x = 60

Therefore, there were 60 audience members at the seminar.

Step-by-step explanation:

According to the given situation,

the area of figure A= l*b

                                =4m * 5m

                                =20m²

As the measures of the figure A and B is same,

the area of figure B = the area of figure A=20m²

the length of the side C and D are = 16m-8m-4m=4m

the area of figure C = l * b

                                 =4m*5m

                                 =20m²

As the measures of the figure C and D is same,

the area of figure D = the area of figure C=20m²

Area of the figure E=l * b

                               =8m * 13m

                               =104m²

∴ the area of the shaded region is =184m²

Answer: The decay rate is 8.4%, which means that the sample will have 91.6% of its original mass after one year, 91.6% of that amount after two years, and so on.

Therefore, we can write the relationship between y and t as:

y = 600 * (0.916)^t

This is an exponential decay function, where the initial value is 600 milligrams and the decay factor is 0.916 (1 minus the decay rate of 8.4%). As time t increases, the mass of the sample y decreases exponentially.

Step-by-step explanation:

la cantidad buscada es 1440.

Para encontrar la cantidad dada el 15% de la misma, podemos usar una ecuación:

15% de x = 216

Podemos convertir el porcentaje a decimal dividiendo por 100:

0.15x = 216

Luego, para despejar x, podemos dividir ambos lados de la ecuación por 0.15:

x = 216 / 0.15

x = 1440

The answer to the given question about inscribed angles intercepting an arc is option A. 100

As we know that the measure of an inscribed angle is half the measure of the intercepted arc, we can use the formula:

Measure of inscribed angle = 1/2 × Measure of intercepted arc

So, if the intercepted arc has a measure of 200 degrees, then the measure of the inscribed angle is:

Measure of inscribed angle = 1/2 × 200 degrees

= 100 degrees

Therefore, the answer is A. 100 degrees. In a circle, an inscribed angle is an angle formed by two chords of the circle that have a common endpoint on the circle. The measure of an inscribed angle is half the measure of the intercepted arc. Therefore, if an arc has a measure of 200, then an inscribed angle that intercepts that arc will have a measure of half of 200, which is 100 degrees.

Another mathematical representation of how a rider on this Ferris wheel might move is :y =  cos(0.25x) + 40

Trigonometry is widely used in many fields, including physics, engineering, architecture, surveying, oceanography, and more. Here are several examples:

In astronomy and physics, trigonometry is used to compute the motions of moving objects, gauge the separations between planets and stars, and examine waves. Trigonometry is used in architecture and engineering to determine angles and distances for building structures like bridges and buildings.

In surveying, trigonometry is a tool used to determine angles and separations between points on the surface of the ground.

.

The function y = a cos(bx) + c, where an is the function's amplitude, b is its frequency, and c is its vertical shift, can be used to mimic the height of a rider on a Ferris wheel.

Given that the Ferris wheel's diameter in this instance is 60 meters, its radius is 30 metres. The Ferris wheel's center axle is 40 metres off the ground. This indicates that a rider is 70 metres above the earth when they are at the top of the Ferris wheel (30 + 40). A rider is 10 metres above the ground when they reach the bottom of the Ferris wheel. (40 - 30).

We can determine that the Ferris wheel's period is four minutes because it rotates once every four minutes. The following formula can be used to get our function's frequency:

f = 1/T, 1/4, and 0.25 Hz

Therefore, our function has a frequency of 0.25 Hz.

The vertical shift of our function is equivalent to 50% of the difference between a Ferris wheel passenger's maximum and minimum heights:

, c = (a_max + a_min) /2

c = (70 + 10) /2

c = 40

Therefore, 40 is the vertical shift of our function.

Finally, we must ascertain the function's amplitude. The difference between a Ferris wheel passenger's maximum and minimum heights is equal to half of the amplitude:

For example, c = (a_max + a_min) / 2 c = (70 + 10) / 2 c = 40

Therefore, 40 is the vertical shift of our function.

Finally, we must ascertain the function's amplitude. The difference between a Ferris wheel passenger's maximum and minimum heights is equal to half of the amplitude:

A=(a_max - a_min) / 2 A=(70 - 10) / 2 A=30

Therefore, our function has an amplitude of 30.

When you combine everything, you get:

Y equals a cos(0.25x) + 40

y = -25 cos(C), where C is the time in minutes since the motion started at position, is another potential mathematical model that could describe this motion. (0,-25).

Given that 60% of Olivia's fruit salad is made up of apples as opposed to Amadou's fruit salad's 52.63%, Olivia's fruit salad will have a more apple-forward flavor based on percent.

The amount of apples in each fruit salad needs to be compared in order to determine which salad will taste more apple-like.

There are 19 cups of fruit in Amadou's fruit salad, of which 10 cups are apples. By dividing the total number of cups of fruit by the number of cups of apples, and multiplying the result by 100, we can get the proportion of apples in Amadou's salad:

Apple's percent of Amadou's fruit salad is equal to (10/19) x 100, or 52.63%.

There are 5 cups of fruit in Olivia's fruit salad, of which 3 cups are apples. We can use the same formula to determine how much apple is in Olivia's salad:

Olivia's fruit salad contains 60% apples, or (3/5) x 100.

As a result, Olivia's fruit salad will taste more apple-like because apples make up 60% of it as opposed to only 52.63% of Amadou's fruit salad.

It is important to keep in mind that the maturity, sweetness, and freshness of the fruits used, as well as other elements like the dressing and presentation, may all affect how the fruit salad tastes.

Answer:

the concentration of sugar in the tank after 10 minutes is approximately 0.056 pounds per gallon.

Step-by-step explanation:

Let's first calculate the amount of sugar that will be added to the tank during the 10 minutes:Amount of sugar added = rate of sugar * time = 2 pounds/minute * 10 minutes = 20 poundsThe initial amount of water in the tank is 300 gallons, and 20 gallons per minute are being added, so after 10 minutes, the amount of water in the tank will be:Amount of water in the tank = initial amount of water + rate of water * time = 300 gallons + 20 gallons/minute * 10 minutes = 500 gallonsTherefore, after 10 minutes, the total volume of the mixture in the tank will be 500 gallons, and the total amount of sugar in the tank will be 8 + 20 = 28 pounds.To find the concentration of sugar in the tank, we divide the total amount of sugar by the total volume of the mixture:Concentration of sugar = total amount of sugar / total volume of mixture = 28 pounds / 500 gallons ≈ 0.056 pounds per gallon

We can use the formula:

concentration = (total sugar added in pounds) / (total water in gallons)

First, we need to find out how much sugar is added in 10 minutes. Since sugar is being added at a rate of 2 pounds per minute , in 10 minutes, we will have:

total sugar added = 2 pounds/minute * 10 minutes = 20 pounds

Next, we need to find out how much water is in the tank after 10 minutes. Since water is being added at a rate of 20 gallons per minute , in 10 minutes, we will have:

total water added = 20 gallons/minute * 10 minutes = 200 gallons

Therefore, the total amount of water in the tank after 10 minutes is:

total water = 300 gallons (initial water) + 200 gallons (water added) = 500 gallons

Finally, we can calculate the concentration of sugar in the tank by plugging in the values:

concentration = total sugar added / total water

concentration = 20 pounds / 500 gallons

concentration = 0.04 pounds/gallon

Therefore, after 10 minutes, the concentration of sugar in the tank is 0.04 pounds per gallon.

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle may be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

x = 3h - 1

A = (1/2)bh

The estimated probability that it takes 10 or fewer shots to get his first successful shot is:

P(10 or fewer shots) ≈ 0.825

What is probability?

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.

To estimate the probability that it takes 10 or fewer shots to get his first successful shot, we need to add up the number of dots for the first 10 bars on the dot plot.

From the given dot plot, we can see that the number of dots for each value up to 10 shots are:

0 + 9 + 6 + 5 + 4 + 4 + 2 + 2 + 0 + 1 = 33

Therefore, the estimated probability that it takes 10 or fewer shots to get his first successful shot is:

P(10 or fewer shots) ≈ 33/40

This can also be written as a decimal:
