IF M∠J = 82, M∠L = 57, AND M∠K = 41, list the sides of JLK in order from smallest to largest.
angle list: k,l,j:
sides are: LJ, KJ, KL
To find the sides of triangle JLK in order from smallest to largest, we need to compare the measures of the angles. The side opposite the largest angle is the longest side, so we can determine the order of the sides based on the angle measures.
Explanation:The triangle JLK has angles J, L, and K with measures 82, 57, and 41 degrees, respectively. To determine the sides of JLK in order from smallest to largest, we can use the fact that the side opposite the largest angle is the longest side. So, we need to identify the largest angle and its corresponding side.
Comparing the measures of the angles, we can see that M∠J is the largest angle. Therefore, the side opposite angle J, which is side JL, is the longest side. Next, we compare the measures of the remaining angles. M∠L is the next largest angle, so the side opposite angle L, which is side LK, is the second longest side. Finally, M∠K is the smallest angle, so the side opposite angle K, which is side JK, is the shortest side.
Therefore, the sides of triangle JLK in order from smallest to largest are JK, LK, JL.

Question:
Crispy clover, a popular vegetarian restaurant, introduced a new menu that had 20% more dishes than the previous menu. The previous menu had D dishes. Which of the following expressions could represent how many dishes crispy clovers new menu has?
Answer:
The expression could represent how many dishes crispy clovers new menu has is:
[tex]D + \frac{1}{5}D \text{ or } 1.2D[/tex]
Solution:
Given that,
The new menu had 20% more dishes than the previous menu
The previous menu had D dishes
Therefore,
Previous menu = D dishes
New menu = 20 % more dishes than previous menu
Which means,
New menu = 20 % of previous menu + previous menu
Therefore,
New menu = 20 % of D + D
Solve the above equation
[tex]New\ menu = 20 \% \times D + D\\\\New\ menu = \frac{20}{100} \times D + D\\\\New\ menu = 0.2 \times D + D\\\\New\ menu = 0.2D + D = \frac{D}{5} + D = 1.2D[/tex]
Therefore, new menu has 1.2D dishes

Total distance walked by Layla is 300 yards
Solution:
Given that,
Layla is walking in a rectangular park
She walks one side that is 50 yards and then the other side that is 120 yards
Length = 120 yards
Width = 50 yards
Layla develops a cramp in her leg and walks diagonally through the park to head back home
Let us find the length of diagonal of rectangle
[tex]d=\sqrt{w^2+l^2}[/tex]
[tex]d = \sqrt{50^2+120^2}\\\\d = \sqrt{2500+14400}\\\\d = \sqrt{16900}\\\\d = 130[/tex]
Thus length of diagonal is 130 yards
What is the total distance that layla walked?
Given that Final answer is perimeter of the triangle park
The diagonal and length and width forms a right angle triangle
Perimeter of triangle = diagonal length + width + length
Perimeter of triangle = 130 + 50 + 120 = 300
Thus total distance walked by Layla is 300 yards
The total distance Layla walked, including the two sides of the park and the diagonal path, is calculated using the Pythagorean theorem to be 300 yards.
Explanation:The question asks us to find the total distance Layla walked while going through the rectangular park diagonally. Layla first walks one side of the park which is 50 yards long and then the adjoining side which is 120 yards long. To do this, we will first find the length of the diagonal using the Pythagorean theorem and then add it to the sum of the two sides she walked to get the total distance. The Pythagorean theorem states that in a right-angled triangle the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written as c2 = a2 + b2.
Applying the Pythagorean theorem to find the diagonal (hypotenuse):
Let a = 50 yards (length of the first side)Let b = 120 yards (length of the second side)c2 = a2 + b2 = 502 + 1202c2 = 2500 + 14400c2 = 16900c = √16900 = 130 yards (length of the diagonal)Now, we can find the total distance Layla walked:
Distance along the first side = 50 yardsDistance along the second side = 120 yardsDistance diagonally across the park = 130 yardsTotal distance = 50 yards + 120 yards + 130 yardsTotal distance = 300 yardsTherefore, the total distance Layla walked is 300 yards.

how many and what type of solutions does the equation have 17+3x^2=6x
A. no real solution
B. one real solution
C. two rational solutions
D. two irrational solutions
Option D: Two irrational solutions
Explanation:
The equation is [tex]17+3 x^{2}=6 x[/tex]
Subtracting 6x from both sides, we have,
[tex]3x^{2} -6x+17=0[/tex]
Solving the equation using quadratic formula,
[tex]x=\frac{6 \pm \sqrt{36-4(3)(17)}}{2(3)}[/tex]
Simplifying the expression, we get,

Taking out the common terms and simplifying, we have,
[tex]\begin{aligned}x &=\frac{2(3 \pm i \sqrt{42})}{6} \\&=\frac{(3 \pm i \sqrt{42})}{3}\end{aligned}[/tex]
Dividing by 3, we get,
[tex]x=1+i \sqrt{\frac{14}{3}}, x=1-i \sqrt{\frac{14}{3}}[/tex]

B. 2x + y = 12
C.-7x- 5y = -48
D. 7x - 5y = 48
Answer:
C. -7x- 5y = -48
Step-by-step explanation:
The vector AB is ...
AB = B -A = (4, 4) -(-3, -1) = (4+3, 4+1) = (7, 5)
The dot-product of this vector and the one in the direction of the line through B will be 0:
(7, 5)·(x -4, y -4) = 0
7(x -4) +5(y -4) = 0
7x +5y -48 = 0
Multiplying by -1 gives the form we see in answer choice C:

(1.3x + 2.4) - (6.1x - 3.2)
The expression (1.3x + 2.4) - (6.1x - 3.2) simplifies to -4.8x + 5.6 after distributing the negative sign and combining like terms.
To solve the expression (1.3x + 2.4) - (6.1x - 3.2), we'll distribute the negative sign inside the second parentheses and then combine like terms:
(1.3x + 2.4) - (6.1x - 3.2)
Distribute the negative sign:
1.3x + 2.4 - 6.1x + 3.2
Combine like terms:
(1.3x - 6.1x) + (2.4 + 3.2)
Combine the x terms:
-4.8x + 5.6
So, (1.3x + 2.4) - (6.1x - 3.2) simplifies to -4.8x + 5.6.

an average Scott makes a basket 9 times out of 12 when he is practicing how many baskets can he expect to make when he tried 200.
Answer:
150
Step-by-step explanation:
We know that Scott's ratio of making the basket is 9/12. All we need to do is find out how many baskets he'll make if he attempts 200 shots.
So, 9/12 needs to become x/200. We don't know what x is yet, but there's a shortcut.
9/12 can be simplified by dividing 3 on the top and bottom.
9/12 ÷ 3/3 = 3/4
We can then see how many times 4 can go into 200.
200/4 = 50
So, we multiply 3/4 by 50 on both the top and bottom.
3/4 × 50/50 = 150/200.
So, if he attempts 200 shots then he'll make 150 of them.
Scott can expect to make approximately 150 baskets if he attempts 200 shots with his success rate being 9 out of 12, which equates to a 75% success rate.
Explanation:The question asks how many baskets Scott can expect to make if he tries 200 shots given that his average success rate is 9 out of 12. To find the answer, we can set up a proportion because Scott's shooting is a matter of probability and ratios. First, we determine Scott's success rate as a fraction: 9/12 which simplifies to 3/4 or a success rate of 75%.
Then, we apply this success rate to the new number of attempts (200) to find the expected number of successful baskets:
Expected number of baskets = Success rate x Total attemptsExpected number of baskets = (3/4) x 200Expected number of baskets = 150Therefore, if Scott attempts 200 shots, he can expect to make approximately 150 baskets.

(-5x - 3)(-5x + 3)
Step-by-step explanation:
Difference of squares is a special type of factoring when you are subtracting two numbers that are perfect squares. Perfect squares are numbers that, when you find its square root, it is a whole number.
Difference of squares follows this rule:
a² - b² = (√a² - √b²)(√a² + √b²) = (a - b)(a + b)
Notice in the factored form, you take the same number in both brackets. In one set of brackets you add the numbers. In the other brackets, you subtract the numbers.
In (-5x - 3)(-5x + __), the blank in the second bracket will use the same number as the second number in the first brackets.

A square prism measuring 6 km along each
edge of the base and 5 km tall. Find area
Final answer:
The total surface area of a square prism with a base edge of 6 km and height of 5 km is 192 km².
Explanation:
The question is about finding the surface area of a square prism (also known as a rectangular prism where the base is a square). A square prism has six faces: two square bases and four rectangular sides. To find the total surface area, we calculate the area of each face and sum them up.
The formula for the area of a square is side × side. Since the base of the prism is a square with each side measuring 6 km, the area of one square base is:
Area of one square base = 6 km × 6 km = 36 km²Since there are two square bases:
Total area of two square bases = 36 km² × 2 = 72 km²The formula for the area of a rectangle is length × width. The four rectangular sides each have one dimension that is the height of the prism (5 km), and the other dimension is the length of a side of the base (6 km), so:
Area of one rectangular side = 5 km × 6 km = 30 km²There are four such sides:
Total area of four rectangular sides = 30 km² × 4 = 120 km²Adding the areas of the bases and the sides:
Total surface area of the prism = 72 km² + 120 km² = 192 km²Can anyone help me with theses problems?

To solve this ratio problem, we need to determine the relationship between the given numbers and apply it to find the answer.
Explanation:The given expression is:
9:3 :: 49 :
To solve this, we need to determine the relationship between 9 and 3, and then apply the same relationship to 49.
The symbol '::' represents the ratio or proportion between the numbers before and after it.
9 divided by 3 is equal to 3, so the relationship here is that the first number is three times the second number.
Now, let's apply the same relationship to 49:
49 divided by 3 is equal to 16.33, so we can say that the answer is 16.33.

#SPJ3
The final answer is 9 : 3 :: 49 : 16.33.
Here's a step-by-step solution:
We need to find the missing number such that the ratios are equivalent. This can be written as a proportion: 9/3 = 49/x.First, simplify the left side: 9/3 = 3.So, we have: 3 = 49/x.Next, solve for x by multiplying both sides by x: 3x = 49.Finally, divide both sides by 3 to isolate x: x = 49/3.Therefore, x = 16.33 (rounded to two decimal places).The answer to the question is therefore 49 : 16.33.
The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exercising.
The function g(x) = 2x + 125 represents the calorie deficit that occurs when following a particular diet, where x is the number of hours spent exercising.
What is (f + g)(2)? Explain.
Hey there!
When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.
Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).
That can be simplified to 4x + 335.
So, (f + g)(x) = 4x + 335.
Let's plug 2 in for x and solve.
(f + g)(2) = 4(2) + 335
Multiply.
(f + g)(2) = 8 + 335
Add.
(f + g)(2) = 343
The x value is consistent for the values of both equations, in both x is defined as the number of hours spent exercising.
So, (f + g)(2), which is 343, is the amount of calories burned and the calorie deficit on a diet when 2 hours are spent exercising.
