Answer: 5 cm

Step-by-step explanation:

We know that 3x + 2x makes up one side of the square. Recall that the formula for a square's perimeter is P = 4a. Thus:

(3x + 2x) * 4 = 100

5x * 4 = 100

20x = 100 (divide by 20)

x = 5 (cm)

The measure of angle 8 is 118°, and the measure of the angle opposite to it, angle 6, is 62°.

If lines v and w are parallel and angle 1 (denoted as <1) measures 62°, then angle 8 (denoted as <8) is supplementary to <1 (since they are corresponding angles on the same side of the transversal line) and thus measures 180 - 62 = 118°.

When two straight lines are cut by a transversal line, corresponding angles on the same side of the transversal are equal. Therefore, <8 and <1 are equal in measure. By transitivity, <8 is also equal in measure to the angle that is opposite it and adjacent to <1, which we could denote as <6.

We can apply the same reasoning to find the measure of angle 6. Since line v is parallel to line w, angle 6 and angle 1 are alternate interior angles, and thus are equal in measure. Therefore, <6 also measures 62°, and this is the measure of the angle opposite to angle 8.

The number of dimes that Paula had in the purse is  0 dimes .

In the question ,

it is given that ,

the average value of all the pennies , nickels , dimes and quarters = 20 cents .

let the total value (in cents )that Paula has originally be "v" ,

let the number of coin she had be "n" ,

that is , v/n = 20

So ,v = 20n

if she had 1 more quarter means the value of all the coins = v + 25

and number of coins becomes = n + 1

the new average is given as 21,

that means ,

(v + 25)/(n + 1) = 21

v + 25 = 21(n+ 1)

v + 25 = 21n + 21

Substituting the value of v = 20n , we get

20n + 25 = 21n + 21

21n - 20n = 25 - 21

n = 4

and v = 20(4) = 80

and the only way that Paula can satisfy this rule is,  if she had 3 quarters and 1 nickel in her purse.

Therefore , The number of dimes that Paula had in the purse is  0 dimes .

The given question is incomplete , the complete question is

The average value of all the pennies, nickels, dimes, and quarters in Paula's purse is 20 cents. if she had one more quarter, the average would be 21 cents. How many dimes does she have in her purse ?

Karen got an 89 on one quiz and must take two more quizzes to maintain her current average score.

To maintain the current average score, we have to first determine the current average score. The average of scores is calculated by dividing the total of all scores by the number of scores.

To get the current average score, we need to add Karen's score to the total score of the previous quizzes and divide by the number of quizzes.

The following formula is used to find the mean or average score:

Mean score = (Total score of all quizzes) / (Number of quizzes)

Let's say Karen took n quizzes before the current quiz. Therefore, to find the current mean score, we would add up the previous n scores and Karen's current quiz score.

The sum is then divided by n + 1 as there are n + 1 scores, including the current quiz score. That is, the formula becomes:

Mean score = (Total score of all quizzes) / (Number of quizzes)

Mean score = (Score of Quiz 1 + Score of Quiz 2 + … + Score of Quiz n + Karen's current score) / (n + 1)

We are given that Karen got an 89 on one of the quizzes. If the current average is 85, then the sum of all Karen's scores must be 85 × (2 + n) (since there are two more quizzes remaining after the quiz where she got 89).

Thus, the following equation can be written:

Mean score = (85 × (2 + n) + 89) / (n + 3)

We are looking for Karen's next score that will maintain her current mean score. In other words, we need to find the score Karen must obtain in the next quiz so that her current mean score of 85 remains the same. So, we equate the current mean score and the new mean score (when the new score is included) and solve for the new quiz score as follows:(85 × (2 + n) + 89) / (n + 3) = (85 × (2 + n) + x) / (n + 3)Where x is Karen's next score.

Therefore:(85 × (2 + n) + 89) / (n + 3) = (85 × (2 + n) + x) / (n + 3) 85 × (2 + n) + 89 = 85 × (2 + n) + x x = 89

Thus, the score Karen needs to get on the second quiz is 89.

Therefore, Karen needs to get 89 on the other quiz to maintain her current average. The total score of the three quizzes would be:

85 × (2 + n) + 89 + 89 = 85 × (4 + n) + 89.

Hence, the answer is:

Karen needs to get an 89 on the second quiz to maintain her average score.

Answer:

A) d = \(\frac{C}{\pi}\)

B) d = \(\frac{8}{\pi}\) or 2.55 inches

C) r = 3 inches

Step-by-step explanation:

Given the formula for the circumference of a circle, C = πd, where d represents the diameter of a circle.

In order to solve for d, divide both sides of the equation by π:

\(\frac{C}{\pi} = \frac{\pi d }{\pi}\)

d = \(\frac{C}{\pi}\).

Given the circumference of the circle, C = 8 inches:

Use the formula for the diameter of the circle from part A of this post.

d = \(\frac{C}{\pi}\)

d = \(\frac{8}{\pi}\) or 2.55 inches.

Since the diameter of a circle is the same as twice the measure of the radius, r:  d = 2 × r

Then, we can rewrite the formula for the circumference of a circle as:

C = 2πr

Divide both sides by 2π to isolate r :

\(\frac{C}{2\pi } = \frac{2\pi r}{2\pi }\)

r = \(\frac{C}{2\pi }\)

Given the circumference of a circle, C = 6π:

\(r = \frac{6\pi }{2\pi } = 3\)

Therefore, the radius of the circle is 3 inches.

The median number of newspapers sold over seven weeks is 223.

The median is the middle score for a data set arranged in order of magnitude. The median is less affected by outliers and skewed data.

The formula for the median is as follows:

Find the median number of newspapers sold. (87, 87, 215, 154, 288, 235, 231)

We'll first arrange the data in ascending order.87, 87, 154, 215, 231, 235, 288

The median is the middle term or the average of the middle two terms. The middle two terms are 215 and 231.

Median = (215 + 231)/2

= 446/2

= 223

In statistics, the median measures the central tendency of a set of data. The median of a set of data is the middle score of that set. The value separates the upper 50% from the lower 50%.

Hence, the median number of newspapers sold over seven weeks is 223.

Jana, because she has the highest ratio since 8/10 is greater than 9/12.

A ratio is a comparison of two numbers or quantities expressed in relation to each other. It represents the relative size or magnitude of one quantity with respect to another. Ratios are typically written as a fraction, with the first number being the numerator and the second number being the denominator, and can also be expressed as a decimal or percentage.

Batting average is a statistical measure used in baseball to evaluate a player's performance at the plate. It is calculated as the ratio of a player's total number of hits to their total number of at-bats (the number of times they attempt to hit the ball).

In the given question,

A higher batting average indicates a better performance, since it means the player is successfully hitting the ball more often.

In this case, we are given the number of hits and attempts for two players, Jana and Tasha. To compare their batting averages, we need to calculate the ratio of their hits to their attempts.

Jana has hit the ball 8 times out of 10 attempts, so her batting average is 8/10 = 0.8.

Tasha has hit the ball 9 times out of 12 attempts, so her batting average is 9/12 = 0.75.

To determine which player has the better batting average, we compare their ratios. Since 0.8 is greater than 0.75, Jana has the higher ratio and therefore the better batting average.

So, the answer is Jana, because she has the highest ratio (8/10 = 0.8), which means she has the better batting average compared to Tasha (9/12 = 0.75).

The equation to relate the flow of water from the 8-inch pipe (1600) to the flow of water from the 4-inch pipe (2400) is 2400.

To relate the flow of water from the 8-inch pipe to the flow of water from the 4-inch pipe, we can use the equation of continuity, which states that the product of the cross-sectional area of a pipe and the velocity of the fluid is constant.

Let's assume that the velocity of water flowing through the 8-inch pipe is V1 and the velocity of water flowing through the 4-inch pipe is V2. The cross-sectional area of the 8-inch pipe is A1 = π\((8/2)^2\) = 64π square inches, and the cross-sectional area of the 4-inch pipe is A2 = π\((4/2)^2\) = 4π square inches.

According to the equation of continuity, A1 * V1 = A2 * V2.

Substituting the given values, we have:

64π * V1 = 4π * V2

Simplifying, we get:

16V1 = V2

So, the equation to relate the flow of water from the 8-inch pipe (1600) to the flow of water from the 4-inch pipe (2400) is:
