Answer:
17
Step-by-step explanation:
From Pythagoras :
Hypotenus = sqrt(opposite² + adjacent²)
From the diagram
l = sqrt((l-9)² + 15²)
l² = (l² - 18x + 81 + 225)
Square both sides
l² = l² - 18x + 306
l² - l² = 306 - 18x
18l = 306
l = 306/18
l = 17

Kevin has these shirts in his closet.
• 3 blue shirts
• 5 red shirts
• 3 purple shirts
• 4 white shirts
Kevin will randomly choose one shirt, not put it back and then choose another shirt. What is the probability that he will choose a red shirt and then a white shirt?
Answers
Since there are a total of 15 shirts,
5 red shirts+4 white shirts= 9 shirts total
3 blue shirts+3 purple shirts= 6 shirts total
The odds that you would pick a red shirt and then a white are 3:2
3 being the 9 red and white shirts combined.
2 being the 6 purple and blue shirts combined.
9:6 simplified=3:2
9/3=3
6/3=2
3:2
Answer: The odds that you would pick a red shirt then a white shirt would be 3:2 or 60%

Kai's mom gave him $25 to spend at the book fair. Kai wants to buy as many books as he can. The
cost of each book is $3. He also wants to buy one poster for $2. Write an inequality to show how
many books he can buy. Highlight your inequality in green. Then,solve the inequality
Answers
Answer:
7 books
Step-by-step explanation:
i cant write it in an equaction but basically 25 - 2 = 23
then 3 x 7 = 21 so he can only buy 7 books and he'll have 2 dollars left
3x +2 =25
-2 -2
23
3x = 23
23 divided by 3 = 7

The area of a circle is 4π in². What is the circumference, in inches? Express your answer in terms of π.
Answers
Answer:
C = 4π in
Step-by-step explanation:
We require to find the radius r of the circle
Given the area is 4π , then
πr² = 4π ( divide both sides by π )
r² = 4 ( take the square root of both sides )
r = [tex]\sqrt{4}[/tex] = 2
Then
C = 2πr = 2π × 2 = 4π inches
Answer:
4π in
Step-by-step explanation:
The formula for area is πr². We will work backwards from 4π. First, I will do √4 so I can find r.
√4 = 2
Now, I know that r = 2. Next, I will substitute r into the circumference formula which is 2πr.
2π(2) - I know r is 2 from my previous set.
Now, I will simplify.
2 · 2 π = 4π
Since the question is asking in terms of π, I will not simplify all the way, and leave pi as is.
