One circle has a circumference half as large as that of a second circle what ratio compares the diameter of the first circle

Answers

The diameter of the first circle is 1/2 the diameter of the second circle.

These are linear measurements.  This means that the ratio of the circumference, distance around, of two circles is the same as the ratio of their diameters, or distance across.

The diameter of first circle is half of the second one.

What is a circle?

A circle is a geometric shape, all of which points are equidistant from a fixed point called as the Centre. The centre of the circle does not lie on it. The tangents drawn from the same point outside a circle are equal in length.

The given problem can be solved as follows,

The circumference of a circle is given as C = πd where d is the diameter of the circle.

Suppose, the circumference and diameters for both the circles are C₁, d₁ and C₂,d₂ respectively.

Now, the expression for circumference can be written as,

C₁ = πd₁

And, C₂ = πd₂

As per the question C₁ = 1/2C₂, then the following equations can be written as,

πd₁ = 1/2πd₂

⇒ d₁ = 1/2d₂

Hence, the diameters of the two circles are also in the same ratio.

The diameter of a basketball rim is 18 inches. A standard basketball has a circumference of 30 inches. What is the distance between the ball and the rim in a shot in which the ball goes exactly in the center of the rim? Show your work.

Answers

we know that
circumference=2*pi*r-------> r=circumference/(2*pi)
circumference=30 in
r=circumference/(2*pi)------> 30/(2*pi)-----> 4.7746 in
the radius of a standard basketball is 4.77 in

the distance between the ball and the rim is equal to
radius of a basketball rim minus radius of a a standard basketball  
radius of a basketball rim =18/2------> 9 in
radius of a a standard basketball=4.77 in


the distance between the ball and the rim=[9-4.77]------> 4.23 in

the answer is
4.23 in
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above:

 - The diameter of a basketball rim is 18 inches.
 - A standard basketball has a circumference of 30 inches. 

 2. Therefore, the diameter of the standard basketball is:

 D=30 inches/π
 D=9.54 inches

 3. Therefore you have:

 (18 inches-9.54 inches)=8.45 inches on both sides

 4. Then, the distance the distance between the ball and the rim in a shot in which the ball goes exactly in the center of the rim, is:

 d=8.45 inches/2
 d=4.22 inches

 The answer is: 4.22 inches
 

Find the mean, median, and interquartile for the data set below. Round your answer to the nearest tenth. 27,16,8,5,19,14,22,31,13,5,23,16,8 Mean: Median: Interquartile range:

Answers

mean: 15.92
Median: 26
interquartile range: 14-16

The mean of the data set is 15.9, the median is 16, and the interquartile range is 14.5 after rounding to the nearest tenth.

To find the mean, median, and interquartile range for the data set 27, 16, 8, 5, 19, 14, 22, 31, 13, 5, 23, 16, 8, we need to follow these steps:

Organize the data in ascending order: 5, 5, 8, 8, 13, 14, 16, 16, 19, 22, 23, 27, 31.

Calculate the mean by adding all numbers and divide by the total count. Mean: (5+5+8+8+13+14+16+16+19+22+23+27+31)/13 = 207/13 ≈ 15.9.

Find the median which is the middle number. Since there are 13 values, the median is the 7th number: Median: 16.

For the first quartile (Q1) and third quartile (Q3), divide the list into two halves. The Q1 is the median of the first half, and Q3 is the median of the second half. Q1: Median of 5, 5, 8, 8, 13, 14 ≈ 8.5; Q3: Median of 19, 22, 23, 27, 31 ≈ 23.

Calculate the interquartile range (IQR) by subtracting Q1 from Q3. Interquartile range: IQR = Q3 - Q1 = 23 - 8.5 = 14.5.

The mean is approximately 15.9, the median is 16, and the interquartile range is 14.5.

The length of a rectangle is twice the width. the area is 256 squared. find the length and the width.

Answers

The solution is quite simple. 
First, draw a rectangle. Label two opposite sides as "w", representing the width. Label the other two sides as "2w", since the length is twice the width.
Next, write an equation. In this case, the equation would be 256=2w*w.
Simplify the equation to 2w^2=256. Divide both sides by two to get w^2=128. The width would be the square root of 128. The length would be twice that, so it would be the square root of 256. That would be 16, so the length is 16.

Whst is the remainder when f(x)=x^3+3x^2-10x-4 is diveded by x-3

Answers

The polynomial remainder theorem allows us to calculate the remainder when a polynomial is divided by a linear polynomial:
The remainder of f(x) divided by (x-k) equals f(k).

Thus
f(x)=x^3+3x^2-10x-4 divided by x-3
gives a remainder of
f(3)=27+3(9)-10(3)-4=27+27-30-4=20
Therefore the remainder required is 20.

The remainder when the polynomial [tex]f(x)=x^3+3x^2-10x-4[/tex] is divided by x-3 is found using the Remainder Theorem and is 20.

The remainder when a polynomial f(x) is divided by a linear divisor such as x - 3 can be found using the Remainder Theorem, which states that the remainder is simply f(3). To find the remainder for [tex]f(x)=x^3+3x^2-10x-4[/tex], we substitute x = 3 into the polynomial.

Calculate f(3):

[tex]f(3) = (3)^3 + 3*(3)^2 - 10*(3) - 4[/tex]

f(3) = 27 + 27 - 30 - 4

f(3) = 54 - 34

f(3) = 20

Therefore, the remainder when f(x) is divided by x - 3 is 20.

sam had four test last month his scores were 81 94 83 and 91 what is the median of his scores

Answers

put them in order of least to greatest and then cross out them till you get the middle number. 81,83,91,94. answer is 91.

Final answer:

The median of Sam's test scores (81, 83, 91, 94) is 87, calculated by averaging the two middle numbers after arranging the scores in ascending order.

Explanation:

To find the median of Sam's test scores, we first list the scores in numerical order: 81, 83, 91, 94. Since there are an even number of scores, the median will be the average of the two middle numbers, which are 83 and 91. To find the median, you add those two middle scores and divide by 2: (83 + 91) / 2 = 174 / 2 = 87. Therefore, the median of Sam's scores is 87.

Calculating the median of a set of values involves organizing them in ascending order, as done with Sam's test scores. In cases where there is an even number of values, the median is determined by averaging the two middle numbers. This method ensures a representative central value for the dataset, providing insight into the typical test performance. In Sam's case, with test scores 81, 83, 91, and 94, the median is computed as 87, offering a balanced perspective on his overall performance.

a catering company needs to know how much roast beef to slice for sandwiches for an event.They are making 30 club sandwich, which requires 1/8lb of roast beef each. They are also making 20 french dip sandwiches, which require 1/5lb each. How many pounds of roast beef should they slice in total?

Answers

1/8(30)+1/5(20)= 31/4 = 7.75
You should slice 7 and 3/4 lbs of roast beef
The would need 7 3/4 pounds (8 if you round up) of roast beef.

To find this you'd multiply 30/1 (30 as a fraction) by 1/8. To do so, you multiply straight across which gives you 30/8 or 3 3/4 when simplified. You repeat this process for the next two numbers too (20/1*1/5 = 20/5. Simplified it equals 4). Finally you add 4 and 3 3/4 together to get your answer of 7 3/4. Round up to 8 if needed.

Mary has 7 1/4 yard of fabric. she cuts off 3/4 foot fabric to make the edge even. Mary wants to end up with 3 pieces of fabric that are the same size. how long will each piece be?

Answers

7 1/4 - 3/4 = 6 5/4 - 3/4 = 6 2/4 

6 2/4 ÷ 3 = 26/4 ÷ 3 = 26/4 x 1/3 = 2 1/6

Answer: 2 1/6 yd

Final answer:

Mary has 7 1/4 yards of fabric, and after cutting off 3/4 foot (which is 1/4 yard), she is left with 7 yards. When she divides this equally into 3 pieces, each piece will be 2 1/3 yards long.

Explanation:

Mary has 7 1/4 yards of fabric. To convert the fabric she cuts off, which is 3/4 foot, to yards, we use the fact that 1 yard = 3 feet. Thus, 3/4 foot is 1/4 yard. After cutting off 1/4 yard from her fabric, she is left with 7 yards (7 1/4 yards - 1/4 yard). Mary wants to divide this into 3 equal pieces. To find the length of each piece, we divide 7 yards by 3, which is 2 1/3 yards for each piece.
