Answer:
20 kilograms.
Step-by-step explanation:
First, we need to find the cost per kilogram.
We can do this by dividing 374 by 34.
That gives us 11. So, our cost per kilogram is $11.
Next, to find how many kilograms we can get with $220 dollars, we need to divide 220 by 11.
That leaves us with a final answer of 20 kilograms.

Fingerprint analysis and blood grouping are features that do not change through the lifetime of an individual. Fingerprint features appear early in the development of a fetus, and blood types are determined by genetics. Therefore, each is considered an effective tool for identification of individuals. These characteristics are also of interest in the discipline of biological anthropology—a scientific discipline concerned with the biological and behavioral aspects of human beings. The relationship between these characteristics was the subject of a study conducted by biological anthropologists with a simple random sample of male students from a certain region with a large student population. Fingerprint patterns are generally classified as loops, whorls, and arches. The four principal blood types are designated as A, B, AB , and O. The table shows the distribution of fingerprint patterns and blood types for the sample. Expected counts are listed in parentheses.

Amadou and Olivia are making fruit salads for a picnic. Amadou mixes 9 cups of melon and 10 cups of apple and Olivia mixes 2 cups of melon and 3 cups of apple. Use Amadou and Olivia’s percent of apple to determine whose fruit salad will taste more appley.
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.

A. 100
B. 200
C. 300
D. 50
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.

There was a sample of 600 milligrams of a radioactive substance to start a study. Since then, the sample has decayed by 8.4% each year.
Let t be the number of years since the start of the study. Let y be the mass of the sample in milligrams.
Write an exponential function showing the relationship between Y and t.
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.

A Ferris Wheel is 60 meters in diameter and rotates once every four minutes. The center axle of the Ferris Wheel is 40 meters. from the ground. Write at least 2 mathematical models that represent the motion of the passenger on this Ferris wheel.
y = acos bx +c
y=-25 cos
C. where X = 2.3 min
Another mathematical representation of how a rider on this Ferris wheel might move is :y = cos(0.25x) + 40
What more uses does trigonometry have?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).

A large mixing tank currently contains 300 gallons of water, into which 8 pounds of sugar have been mixed. A tap will open,
pouring 20 gallons of water per minute into the tank at the same time sugar is poured into the tank at a rate of 2 pounds
per minute. Find the concentration (pounds per gallon) of sugar in the tank after 10 minutes.
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.

In a village, 80% of people are Hindus and 2% are Muslims. If 36 people do not follow these two religions, by drawing a Venn diagram find the number of the Hindu.
Explanation:
Assuming the two religions are mutually exclusive, this would mean 80%+2% = 82% of people are either Hindu or Muslim (but not both).
The remaining 100% - 82% = 18% of people are neither religion mentioned.
x = number of people in the village
18% of x = 36
0.18x = 36
x = 36/0.18
x = 3600/18
x = 200
Then,
80% of x = 0.80*x = 0.80*200 = 160 people are Hindu
The Venn diagram is shown below.
Yolanda hiked each day for a week. The first day she hiked mile, the second day she hiked mile, and the third day she hiked 1 mile. By how much did she increase the distance she hiked each day?
the distance she hiked each day, we need to calculate the difference between the distance she hiked on consecutive days. Yolanda increased the distance she hiked by 1 mile each day.
What is the total distance?To find the increase in the distance Yolanda hiked each day, we need to calculate the difference between the distance she hiked on each consecutive day.
The distance Yolanda hiked each day for the first three days can be represented as:
Day 1: d miles
Day 2: [tex]d + 1[/tex] miles
Day 3: [tex]d + 2[/tex] miles
The increase in distance from day 1 to day 2 is [tex](d + 1) - d = 1[/tex] mile.
The increase in distance from day 2 to day 3 is [tex](d + 2) - (d + 1) = 1[/tex] mile.
Therefore, Yolanda increased the distance she hiked by 1 mile each day.

At a seminar, 2/5 of the audience were students, 3/10 of them were retirees. The rest were professionals. There were 18 more students than professionals. How many audience were at the seminar?
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.
Calculate the area of the figure below using the following information:
Area of triangle ABC = 23.85 square units
Area of triangle ACD = 29.4 square units
Area of triangle AED = 26.25 square units
The area of the given polygon ABCDE divided into three triangles ABC, ACD and AED is 79.5 sq. units.
What is a polygon?
A polygon is a closed figure or shape formed using line segments. Smallest polygon is a triangle containing three sides. On the basis of its sides polygons are classified as triangle, quadrilateral, pentagon, hexagon, heptagon, octagon etc. The sum of interior angles of a polygon is found by the formula (n-2)180 , where 'n' refers to the number of sides in a polygon. The sum of exterior angles of any polygon is always equal to 360°. The area of any irregular or regular polygon may be evaluated by dividing the given shape into standard shapes like square, rectangle, triangle etc and then adding up the areas of all shapes.
Here the given pentagon ABCDE is further divided into three triangles,
ABC, ACD and AED
Also given the areas of triangles:
area of ΔABC = 23.85 sq. units
area of ΔACD = 29.40 sq. units
area of ΔAED = 26.25 sq. units
∴The area of given figure= Sum of the areas of ΔABC, ΔACD and ΔAED
=area of ΔABC+area of ΔACD+area of ΔAED
=23.85+ 29.40+26.25
=79.5 sq. units.
The area of the given figure is 79.5 sq. units
