2. In AKLM, m = 5.9 cm, k = 7.1 cm and of 1, to the nearest 10th of a centimeter.
The length of side KL is approximately 4.8 cm.
To solve this problem, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is equal for all sides of the triangle. In other words:
a/sin(A) = b/sin(B) = c/sin(C)
Where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the measures of the angles opposite those sides.
Using the Law of Sines, we can set up the following proportion:
l/sin(L) = m/sin(M)
Where l is the length of side KL, L is the measure of angle KLM (which is 72 degrees), m is the length of side LM, and M is the measure of angle KML (which we can find by subtracting L from 180 degrees).
M = 180 - L
= 180 - 72
= 108 degrees
Now we can substitute the given values into the proportion and solve for l:
l/sin(72) = 5.9/sin(108)
l = sin(72) * (5.9/sin(108))
≈ 4.8 cm (rounded to the nearest 10th of a centimeter)

each. If Lyle sold 21 benches last month (stained and unstained combined) and collected a total of $600,
how many unstained benches did he selle
Answer:
Step-by-step explanation:
u and s are the number or unstained and stained benches sold, respectively.
Lyle sold 21 benches for $600
u + s = 21
s = 21-u
20u + 32s = 600
20u + 32(21-u) = 600

The length of unknown side x is 58.
The correct answer is option D.
To find the unknown side length, x, in a right triangle with the base measuring 42 and the perpendicular measuring 40, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Let x be the hypotenuse. Applying the Pythagorean theorem, we have:
\(x^2 = 42^2 + 40^2\)
Simplifying:
\(x^2\) = 1764 + 1600
\(x^2\)= 3364
Taking the square root of both sides to solve for x:
x = \(\sqrt{3364}\)
Simplifying the square root:
x = (\(\sqrt{4 * 841)}\)
Since 841 is a perfect square (\(29^2\)), we can further simplify:
x = 2 * 29
x = 58
Therefore, the unknown side length, x, is equal to 58.
From the options provided the correct option is D.

Prob-4 Pressurized air are being used in a manufacturing company in its daily operation. There are three compressors in service; two-screw type compressors, (S1 ,S2) and one-reciprocal type compressor,(R). Each compressor, at any given time, is either off (0), or on (1) . Assume that event A is denoted to reciprocal compressor (R) that is always off . Event B is denoted that at least one of the screw type of compressor is always on. Assume that all outcomes in event B are equally likely. If P(A∩B)=45% and P(A∪B)=93%. Compute the probability that all compressors are off
Answer:
The probability that all compressors are off = P(A ∩ B') = 0.18
Step-by-step explanation:
Event A is denoted to reciprocal compressor (R) that is always off.
Event B is denoted that at least one of the screw type of compressor is always on.
P(A) = Probability that the reciprocal compressor is off.
P(A') = Probability that the reciprocal compressor is on.
P(B) = Probability that at least one of the screw type of compressor is on.
P(B') = Probability that at least one of the screw type of compressor is off.
P(A ∩ B) = 45% = 0.45
P(A ∪ B) = 93% = 0.93
P(U) = P(A ∪ B) + P(A' ∩ B')
1 = 0.93 + P(A' ∩ B')
P(A' ∩ B') = 1 - 0.93 = 0.07
The probability that all compressors are off is given as P(A ∩ B')
P(A) = P(A n B') + P(A n B)
P(B) = P(A n B) + P(A' n B)
The question asks us to assume that all outcomes in event B are equally likely.
The possible outcomes in event B include
- The two compressors are on
- First compressor is on, second compressor is off
- Second compressor is on, first compressor is off
- both compressors are off
Since all the outcomes are equally likely, the probability that at least one of the two compressors is on = (3/4) = 0.75 = P(B)
P(B) = P(A n B) + P(A' n B)
0.75 = 0.45 + P(A' n B)
P(A' n B) = 0.75 - 0.45 = 0.30
P(A ∪ B) = P(A ∩ B') + P(A' ∩ B) + P(A ∩ B)
0.93 = P(A ∩ B') + 0.30 + 0.45
P(A ∩ B') = 0.93 - 0.30 - 0.45 = 0.18

What is the difference between the integers negative 11 and -3
Answer:

When comparing -11 and -3, -3 is bigger than -11. Both numbers are negative. A larger negative number is actually smaller than a smaller negative number. So, -3 is greater than -11. To find the difference, subtract -3 from -11 and you get -8.
find the exact value of x. 45 degree and 10 side
Answer:
The exact value of the other leg is 10.
Step-by-step explanation:
Finding the exact value of x given a 45 degree angle and a side length of 10 can be done using trigonometry. In a 45-45-90 right triangle, the two legs are congruent and the hypotenuse is equal to the square root of 2 times the length of the legs.
Therefore, if one leg is 10, the hypotenuse is 10 times the square root of 2. To find the length of the other leg, we can use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the legs of the right triangle.
Substituting known values, we get:
(10√2)^2 = 10^2 + b^2
200 = 100 + b^2
b^2 = 100
b = 10
Therefore, the exact value of the other leg is 10.

The sum of two consecutive natural numbers is 575. Find the numbers. (Enter your answers as a comma-separated list.)
Answer:
Step-by-step explanation:
To find the two consecutive natural numbers whose sum is 575, we can set up the following equation:
x + (x+1) = 575
where x and x+1 are the two consecutive natural numbers.
We can solve this equation by combining like terms:
2x + 1 = 575
Subtracting 1 from both sides, we get:
2x = 574
Dividing both sides by 2, we get:
x = 287
Therefore, the two consecutive natural numbers are 287 and 288. Our final answer is 287, 288.
Answer:
287,288
Step-by-step explanation:
Question
The sum of two consecutive natural numbers is 575. Find the numbers
soln
x +( x + 1) = 575
x + x + 1 = 575
2x + 1 = 575
2x = 575 – 1
2x = 574
\( \frac{2x}{2} = \frac{574}{2} \)
x = 287
since we got x as 287, lets solve(x+1)
by substituting
287 + 1 = 288
hence the consecutive numbers are 287,288
Check
287 + 288 = 575
we are correct.

Furthermore 9 engage in swimming and visit national parks, 9 engage in swimming only while 11 visit national parks only. How many engage in
i. Swimming and cycling
Answer:
Step-by-step explanation:
i am working on the assumption that nobody does all three of them
i got 4 because including the people that do swimming and park, the total number of people that do swimming is 22.
the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.
so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

you spin the spinner once
What is P(5)?
0-10
A spinner is split into 11 different pieces so you are less likely to land on five than the other numbers.
The probability of getting 5 on spinner is 0.25.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, on the spinner there are four numbers {3, 4, 5, 6}.
Number of favorable outcomes = 1
Total number of outcomes = 4
So, P(5) = 1/4
= 0.25

Solve (x+1)2 =13/4 using the square root property
Answer:
Starting with the equation:
(x + 1)^2 = 13/4
We can use the square root property, which states that if a^2 = b, then a is equal to the positive or negative square root of b.
Taking the square root of both sides, we get:
x + 1 = ±√(13/4)
Simplifying under the radical:
x + 1 = ±(√13)/2
Now we can solve for x by subtracting 1 from both sides:
x = -1 ± (√13)/2
Therefore, the solutions to the equation are:
x = -1 + (√13)/2 or x = -1 - (√13)/2

Step-by-step explanation:
Factor 4x²-12x+5x-15
Answer:
\((4x+5)(x-3)\)
Step-by-step explanation:
We can separate this expression into two parts: \(4x^2-12x\) and \(5x-15\).
We can first take the first part and factor out 4x, getting \(4x(x-3)\).
We can then take the second part and factor out 5, getting \(5(x-3).\)
Now when we put these parts together, they make \(4x(x-3)+5(x-3)\\\).
The last step is to factor \((x-3)\) to get \((4x+5)(x-3)\).
