What total length of ribbon is needed to Line the two long sides of the hat?

Answers

Answer:

Total length of ribbon to line the long sides will be 22 in

Step-by-step explanation:

In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.

Then by applying Pythagoras theorem in both the triangles.

h²= (3x + 5)² + (2x + 1)² ------(1)

h²= (5x + 1)² + 5² ------(2)

By equating both the equations

(3x + 5)² + (2x + 1)² = (5x + 1)² + 25

9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25

13x² + 34x + 26 = 25x² + 10x + 26

13x² - 25x² + 34x - 10x + 26 - 26 = 0

- 12x² + 24x = 0

12x² - 24x = 0

x² - 2x = 0

x(x - 2) = 0

x = 2

Now we will put x = 2 in the measure of sides of the kite.

Side 1 = (3x + 5)

          = 3×2 + 5

          = 11

Side 2 = (5x + 1)

          = 5×2 + 1

          = 11

Side 3 = (2x + 1)

          = 2×2 + 1

          = 5

Therefore, Total length of ribbon to line the long sides will be = 11 + 11

= 22 in.

Select the correct answer.A soccer team wins 65% of its matches, and 15% of its matches end in a draw. If the team is scheduled to play 20 matches, about how many
matches is it expected to lose?

Answers

Final answer:

To determine the expected losses for the soccer team, we subtract the percentage of wins and draws from 100% to get the loss percentage. We then multiply this percentage by the total number of scheduled matches (20 matches), which results in an expected 4 matches lost.

Explanation:

To determine how many matches the soccer team is expected to lose, we must first consider the percentage of wins and draws. With the team winning 65% of its matches and drawing 15%, we can deduce that the remaining percentage of matches will be losses. This is because the outcomes (win, draw, lose) must account for 100% of the possible results.

Therefore, we calculate the percentage of losses as 100% - (65% wins + 15% draws) = 100% - 80% = 20%.

If the team is scheduled to play 20 matches, we can calculate the expected number of losses by multiplying the total number of matches by the percentage of losses. Thus, the expected number of losses = 20% of 20 matches = 0.20 × 20 = 4 matches.

What is 12,925 to the nearest ten thousand

Answers

To the nearest ten thousand. I believe 12 is closer to 10 so if you had to say the answer it would be ten thousand.
12,925 is closest to 10,000 because in the thousands place there is a 2 and since 2 is lesser than 5 you round down which gives you 10,000.
