what is the perimeter of triangle KLM? i was only given one side and then 60° and 30°
please help this makes no sense
Answers
Answer:
[tex]18+6\sqrt{3}[/tex]
Step-by-step explanation:
In all 30-60-90 triangles, the side lengths are in the ratio [tex]x:x\sqrt{3}:2x[/tex], where [tex]2x[/tex] is the length of the hypotenuse, or longest side, of the triangle and [tex]x[/tex] is the length of the side that is directly opposite to the 30 degree angle.
The figure consists of three 30-60-90 right triangles (two inside a larger one). The side KL is marked as 6 meters and represents the side opposite to the 30 degree angle of the largest triangle (Since [tex]\angle L=90^{\circ}[/tex] and [tex]\angle K=60^{\circ}[/tex]). Therefore, the hypotenuse (longest side) of the triangle must be [tex]2\cdot 6=12[/tex] and the other leg must be [tex]6\sqrt{3}[/tex].
The perimeter of a polygon is equal to the sum of all the polygon's sides and therefore the perimeter of thing triangle is [tex]6+12+6\sqrt{3}=\boxed{18+6\sqrt{3}}[/tex]

7 x 5e = 105
plz help
Answers
e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
Answer:
e = 3
Step-by-step explanation:
7 × 5e = 105
35e = 105
35e ÷ 35 = 105 ÷ 35
e = 3

Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.
Answers
Step-by-step explanation:
Given
The function is [tex]f(x)=x+4[/tex]
for [tex]x_2>x_1[/tex], we will check the values of [tex]f(x_1)[/tex] and [tex]f(x_2)[/tex]
Take 3 and 4
[tex]f(4)=4+4\\f(4)=8[/tex]
Similarly,

Thus, [tex]f(4)>f(3)[/tex]
Also, [tex]f'(x)[/tex] is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.

x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10
Answer:
[tex]x=-\frac{3}{10}[/tex]
Step-by-step explanation:
2x - 4y = 3
y = 3x
2x - 4(y = 3x) = 3
2x - 4(3x = 3)
2x - 12x = 3
- 10x = 3
- 10x ÷ - 10 = 3 ÷ - 10

Step-by-step explanation:
The areas marked 1, 2, and 3 each take up 1/4 of the box. This means that the probability that you will spin the arrow and land in any of those spaces is 1/4 each.
Areas 4 and 5 are HALF the size of areas 1, 2, and 3. This means that areas 4 and 5 are half of 1/4. Half of 1/4 is 1/8.
The word "or" means that you ADD whatever two probabilities they are asking for. In this case, you add areas 3 and 5. So, add 1/4 + 1/8 = 3/8.
(an easy way to add 1/4 to 1/8 is to change 1/4 to 2/8. Then you can add the two areas easily)

1. Pick two animals to be in a race and answer the following questions.
a. Suppose two animals are in a race. Choose two animals from Table 1 and calculate the speed of each animal in yards per second. (6 points)
Example: Kangaroo – 30 miles/hour multiply by 1760 (conversion to yards) divided by 3600 (conversion to seconds). So the speed of a Kangaroo is 14.67 yd/sec.
b. You decide how much of a head start (in yards) the faster animal will offer the slower animal. For each animal, write an equation relating speed (v), distance from the starting line (d), and time (t). (6 points)
Formula:
c. Graph the two equations on the same coordinate plane. (4 points)
d. How long will it take the faster animal to overtake the slower animal? How many yards from the starting line are the animals when the faster animal overtakes the slower animal? (3 points)
e. Reduce the head start by half and repeat parts (c) and (d) from above. (9 points)
(c)
(d) How long will it take the faster animal to overtake the slower animal? How many yards from the starting line are the animals when the faster animal overtakes the slower animal?
2. Pick a third animal and answer the following questions.
a. Choose a third animal. Calculate its speed in yards per second. Compare its speed with the speed of the two animals you chose in Activity 1. (6 points)
b. Decide which two animals should get head starts and how much of a head start each should get. Write three equations relating distance from the starting line to time. (10 points)
c. Graph all three equations on the same coordinate plane. (6 points)
Part B: Which Community Garden Plan? (50 possible points)

One community member, Nancy, suggests a square garden while another member, Juan, suggests a rectangular garden. You will be in charge of determining which of the two gardens would cover the most area while using the least amount of fencing to surround it. You should show all calculations, and give complete explanations.
1. Nancy’s plans for a square garden include an area of (x2 + 12x + 36) m2. Write expressions for the length and width of this square garden. (8 points)
2. The plans for the square garden shows a length of 12 m. What is the width of the square garden? Using the area from problem 1, what is the value of x? What is the total area of this square garden? (9 points)
3. Juan’s plans include a rectangular garden with an area of (x2 + 14x + 24) m2. Write expressions for the length and width of the rectangular garden. (8 points)
4. The plans for the rectangular garden shows a length that is 6 m. longer than the length of the square garden. What is the width of the rectangular garden? How much shorter is the width of the rectangular garden than the square garden? (9 points)
5. Write expressions for the perimeter of each garden in terms of x. Then find each perimeter for the x-values calculated in the previous questions. (8 points)
6. The Community Garden Club would like the garden that covers the most area possible while requiring the least amount of fencing needed to completely surround it. Which garden plan should they choose? Explain your reasoning using the information you calculated for each garden plan. (8 points)

HYRIGH fararefant et fanter i In a class of 25 student,

Illustrate it with a Venn-diagram and find the number of
students who don't like any of the games. (Ans: 3]
Answers
Given:
Total students in a class = 25
Students who like volleyball = 17
Students who like basketball = 15
Students who like both = 10
To find:
The students who don't like any of the games.
Solution:
We have,
Total students in a class = 25
Students who like volleyball = 17
Students who like basketball = 15
Students who like both = 10
Now,
Students who like only volleyball = 17-10
= 7
Students who like only basketball = 15-10
= 5
Students who don't like any of the games is the difference of total number of students and number of students who like at least one game.
Students who don't like any of the games = 25 - (7+5+10)
= 25 - 22
= 3
Therefore, 3 students don't like any of the games.
