It is 5/8 because it is 5 per 8. You cut up the cookies and not the people. It does not reduce.
Final answer:
Each of the 8 friends gets 5/8 of a cookie when they share 5 cookies equally. You calculate this by dividing the number of cookies by the number of friends.
Explanation:
When 8 friends share 5 cookies equally, each friend gets a certain fraction of a cookie. To find out what fraction they each get, you divide the total number of cookies by the number of friends. In this case, you divide 5 cookies by 8 friends.
The calculation is 5 cookies ÷ 8 friends = 5/8 of a cookie for each friend.
Therefore, this means each friend gets 5/8 of a cookie. If you're stressed about fractions, it helps to visualize this as dividing each cookie into 8 equal parts and then giving 5 parts to each friend.

A recent survey by the cancer society has shown that the probability that someone is a smoker is P(S)=0.19. They have also determined that the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158. What is the probability (rounded to the nearest hundredth) that a random person is a smoker and has lung cancer P(S∩LC) ?
0.35
0.03
0.02
0.83
Answer:
P (S∩LC) = 0.03
Step-by-step explanation:
We are given that the probability that someone is a smoker is P(S)=0.19 and the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158.
Given the above information, we are to find the probability hat a random person is a smoker and has lung cancer P(S∩LC).
P (LC|S) = P (S∩LC) / P (S)
Substituting the given values to get:
0.158 = P(S∩LC) / 0.19
P (S∩LC) = 0.158 × 0.19 = 0.03
A college football stadium holds 45,000 fans. In a random sample of 30 fans, 26 were wearing the colors of the home team. Predict the number of fans who are wearing the colors of the home team.
Answer:
38,999
Step-by-step explanation:
In your sample you have 26 out of 30. I like to get that number into a percentage, so you do 26 divided by 30
26/30 = .8666
Then you take your total amount of fans, 45,000 and multiply it by your percentage wearing team colors.
45,000 x .8666 = 38,999.97
Since you can't have .97 of a person, your round it down to 38,999.

What is the total number of digits required in numbering the pages of a book which has 53 pages?
Answer:
The total number of digits required in numbering the pages of a book that has 53 pages would be: 97.
Step-by-step explanation:
This answer would be 97 due to the first nine digits being singular.
The next 44 digits are double, so therefore, you multiply 44 by 2, and you end up with 88.
After that, you take 88 and add the 9, which, is 97 digits in total that you would need to number a 53 page book.

The area of the green square is 9 ft2. The area of the yellow square is 25 ft2.
What is the area of the red square (labelled "b" in the diagram)?
Answer:
the answer is 16Ft^2
Step-by-step explanation:
Square A's area is 9 so take its square root =3
then do the same for Square c =5
then use pythagram theory which is
3^2 + 5^2 = 4^2 = 16
Answer:
area = 16 ft²
Step-by-step explanation:
The area of the green square = 9 ft²
area of the yellow square = 25 ft²
Area of the red square can be computed as follows:
area of a square = L²
Since one side of each triangle forms a part of the triangle knowing the length of sides of the green and yellow triangle can be use to get the sides of the red square and invariably the area.
Green square
L² = 9
square both sides
√L² = √9
L = 3 ft
Yellow square
L² = 25
square both sides
√L² = √25
L = 5 ft
use Pythagoras theorem to get the third side of the triangle which is the b
c² = a² + b²
b² = c² - a²
a = 3 ft
c = 5 ft
b² = 5² - 3²
b² = 25 - 9
b² = 16
square both sides
√b² = √16
b = 4
Red square
area = L²
area = 4²
area = 16 ft²
Need help with Geometry
Answer:
Answer: 56*pi
Step-by-step explanation:
The easiest way is to find the area of the circle and subtract the area of the sector.
Area of the circle
d = 16 cm given
d = 2*r definition
16 = 2*r divide by 2
16/2 = 2r/2
r = 8
Area of the circle = pi * r^2
Area of the circle = pi * 8^2
Area of the circle = 64 pi
Area of the sector
Area of sector = (theta/360) * pi * r^2
Area of sector = 45/360 * pi * 64
Area of sector = 1/8 * pi * 64
Area of sector = 8 * pi
Area of the shaded area
Area of the shaded area = 64 * pi - 8*pi = 56*pi
Note: There is a shorter way, but one can never be confident of getting an angle greater than 180 correct.
360 - 45 = 315
Area of the sector = 315/360 * pi * r2
Area of the sector = 7/8 * pi * 64
Area of the sector = 7 * pi * 8
Area of the sector = 56*pi
the starting salary at a company is $38000 per year.the company automatically gives a raise of 3.5% per year.write the explicit and recursive frmulas for the geometric sequence formed by the salary increase.
Final answer:
The explicit formula for the salary increases represented as a geometric sequence is a_n= 38,000(1.035)^(n-1), and the recursive formula is a_1= $38,000 and a_n= a_(n-1) × 1.035 for n > 1, reflecting an annual raise of 3.5%.
Explanation:
The starting salary at a company is $38,000 per year with an annual raise of 3.5%. To represent the salary increases as a geometric sequence, we need both explicit and recursive formulas.
The explicit formula for a geometric sequence is an= a1 × r(n-1), where a1 is the first term, r is the common ratio, and n is the term number. In this case, a1= $38,000 and r = 1.035 (since the salary increase is 3.5%, or 0.035 in decimal form, plus the original amount, hence 1 + 0.035). Therefore, the explicit formula is an= 38,000(1.035)(n-1).
The recursive formula defines each term based on the previous term. It can be written as a1= $38,000, an= a(n-1) × 1.035, for n > 1. This means that starting from the second year (when n > 1), the salary is obtained by multiplying the previous year's salary by 1.035.

David and Tonya each cut a cylinder in half. The cross-section that results from David's cut is a rectangle. The cross-section that results from Tonya's cut is a circle.
Answer:
Tonya cut the cylinder vertically and David cut it diagonally.
David’s cut along the length of his cylinder resulted in a rectangular cross-section, while Tonya’s perpendicular cut resulted in a circular cross-section. This illustrates principles of geometric cross-sections and plane intersections with solids.
Explanation:In the problem described, David and Tonya are each cutting a cylinder, a geometric shape. The cuts they make, and the cross-sections they create, depend on the orientation of their cuts in relation to the shape of the cylinder.
When David cuts the cylinder, his cross-section result is a rectangle. This implies that he made a longitudinal cut along the length of the cylinder, essentially splitting it from top to bottom.
When Tonya cuts her cylinder, the cross-section is a circle. This means she made a cross-sectional cut perpendicular to the length of the cylinder, slicing it into two equal half cylinders.
This problem illustrates the principles of geometric cross-sections and plane intersections with solids, which are part of the broader field of study in geometry.

Find the measure of an angle with measure between 0 degrees and 360 degrees that is coterminal with an angle measuring 800 degrees.
To find a coterminal angle to 800 degrees within the 0 to 360-degree range, divide 800 by 360 and find the remainder, which is 80 degrees. Hence, 80 degrees is the angle that's coterminal with 800 degrees.
Explanation:To find an angle that is coterminal with 800 degrees, which means an angle that shares the same terminal side as the 800-degree angle but is between 0 degrees and 360 degrees, we use the concept of coterminal angles. Since a complete circle has 360 degrees, we can subtract or add multiples of 360 degrees to any angle to find a coterminal angle.
Here’s how we find it for 800 degrees:
Divide 800 by 360 to find how many complete turns the angle makes: 800 ÷ 360 = 2.22. This shows the angle makes more than 2 full rotations.Find the remainder when 800 is divided by 360 to find the coterminal angle within the 0 to 360-degree range. The remainder is 80 degrees (800 - 720 = 80).Therefore, 80 degrees is the angle between 0 degrees and 360 degrees that is coterminal with an angle measuring 800 degrees.

Step-by-step explanation:
if you look at option c it would be correct because 0.75 (3/4) is bigger than 0.7. Then 11/12 is a bigger proportion then 0.75. there for your answer is correct.
The correct order of the numbers given when converted to decimals for easy comparison is 0.7, 3/4 and 11/12, which corresponds to option b: 0.7 < 3/4 < 11/12.
Explanation:This is a question about comparing and ordering fractions and decimals. To answer this, we first need to convert all the numbers into the same format. We can convert the fractions 11/12 and 3/4 into decimals for easier comparison.
First, to convert 11/12 to a decimal, you'll do the division to find approximately 0.9167. Secondly, 3/4 can be converted to a decimal by performing 3 divided by 4, which equals 0.75. Now, we can easily compare these decimals to 0.7.
From this, we can see that 0.7 is less than 0.75 (3/4) and both 0.7 and 0.75 are less than 0.9167 (11/12). So the correct order of the numbers from least to greatest would be 0.7 < 3/4 < 11/12.
So the correct option is b. 0.7 < 3/4 < 11/12.
