Answer:
12.5
Step-by-step explanation:
In a rectangle, the two diagonals are equal length, so MK = JL = 2x + 9
Note MK = 2 * MN, so
2x + 9 = 2 * (3x + 1)
expand:
2x + 9 = 6x + 2
Solve:
9 - 2 = 6x - 2x
4x = 7
x = 7/4
MK = JL = 2x + 9 = 2 * 7/4 + 9 = 7/2 + 9 = 3.5 + 9 = 12.5

Answer:
TU = 15
Step-by-step explanation:
The two rectangles are similar. That means that the lengths of corresponding sides are in the same ratio.
Pairs of corresponding sides:
MN, ST
NO, TU
OP, UV
PM, VS
Equal ratios of lengths of corresponding sides:
MN/ST = NO/TU = OP/UV = PM/VS
Plug in the given information:
MN/ST = 10/x = 4/6 = PM/VS
10/x = 4/6
4x = 10 × 6
4x = 60
x = 15
TU = 15

A concert promoter is forecasting this year's attendance for one of his concerts based on the following historical data: What is this year's forecast using exponential smoothing with alpha = .2, if last year's smoothed forecast was 15,000?
Answers
The smoothed forecast for this year depends on last years forecast and
observation, as well as the value of alpha.
Response:
The forecast for this year is 16,000What relationship can be used to find the smoothed forecast?The given parameter are;
α = 0.2
From a similar question online, we have the following possible values;
Last year's smoothed forecast, F₄ = 15,000
Last years actual value, A₄ = 20,000
Required:
The forecast this year
Solution:
The exponential smoothing relationship is expressed as follows;
F₅ = F₄ + α·(A₄ - F₄)
Which gives;
F₅ = 15,000 + 0.2 × (20,000 - 15,000) = 16,000
This year's forecast, F₅ = 16,000

Answer:
a. given ∠1≅∠2, the converse of the corresponding angles theorem shows l║m.
Step-by-step explanation:
There are several things you need to know to be able to answer this question.
corresponding angles where a transversal crosses (parallel) lines are angles that are in the same direction from the points of intersection. Here angles 1 and 2 are both "northwest" of the points of intersection, so are corresponding angles.the "corresponding angles theorem" tells you "if the lines are parallel, then corresponding angles at a transversal are congruent."the converse of a theorem "if A, then B" is "if B, then A". Here, the converse of the "corresponding angles theorem" is "if the corresponding angles at a transversal are congruent, then the lines are parallel."__
You are given ∠1 ≅ ∠2, so the hypothesis of the converse of the corresponding angles theorem is already true. The conclusion that the lines are parallel is what you are asked to prove. To prove that, you only need to identify the angles as being corresponding, and invoke the theorem. The logic matches answer choice A.
∠1≅∠2 is given. The diagram shows ∠1 and ∠2 are corresponding angles, so by the converse of the Corresponding Angles Theorem, l║m.

Find the values of x between 0 and pi where the tangent line to the graph of y = sin(x) cos(x) is horizontal.
Answers
Answer:
π/4, or 3π/4
Step-by-step explanation:
dy/dx = cos(x)*cos(x)+sin(x)*[-sin(x)]=(cosx)^2-(sinx)^2=[1-(sinx)^2]-(sinx)^2 = 1-2(sinx)^2
Tangent line is horizontal, so dy/dx = 0
1-2(sinx)^2 = 0
(sinx)^2 = 1/2
sinx = [tex]\frac{1}{\sqrt{2}}, -\frac{1}{\sqrt{2}}[/tex]
Between 0 and pi, sinx >0
so sinx = [tex]\frac{1}{\sqrt{2}}[/tex]
x = π/4, or 3π/4
Pls answer this for brainliest A refrigerator worth Rs.58000 is offered for sale at Rs.45000. What per cent discount is offered during the sale?
Answers
Discounts are used to reduce the price of items
The percentage discount during the sale is 22.41%
How to calculate the percentage discountThe given parameters are:
Worth = Rs 58000
Selling price = Rs 45000
Start by calculating the discount amount
Discount = Worth - Selling Price
So, we have:
Discount = Rs 58000 - Rs 45000
Discount = Rs 13000
The percentage discount is then calculated as:
[tex]\% Discount = \frac{Discount}{Worth}[/tex]
This gives
[tex]\% Discount = \frac{13000}{58000}[/tex]
Simplify
[tex]\% Discount = 22.41\%[/tex]
Hence, the percentage discount during the sale is 22.41%

Answer:
65 degrees
Step-by-step explanation:
All angles of a triangle have to add up to 180 degrees. After establishing that, we can see that there are two angles given. 25 degrees and a 90-degree symbol. So if two angles add up to 115 degrees, we can do 180-115=65 to find the angle of C.
Answer:
m∠C=65°
Step-by-step explanation:
m∠B=90°
m∠A=25°
m∠A+m∠B+m∠C=180°
25°+90°+m∠C=180°
m∠C=180°-(90°+25°)
m∠C=65°

On average, every minute of every day, 167 babies are born. The bar graph represents the results
of a single day of births, deaths, and population increase worldwide.
Each day, the number of births in the world is 45 thousand less than three times the number of
deaths.
a.) If the population increase in a single day is 241 thousand, determine the number of births and deaths per day.
There are____ thousand births per day
There are ____ thousand deaths per day
Answers
Answer:
Let x thousand births per day
Let y thousand deaths per day
Each day, the number of births in the world is 45 thousand less than three times the number of
deaths.
x=3y-45 (1)
Population increase= birth - death
=x-y(2)
substitute (1) into (2)
3y-45-y=241
2y-45=241
2y=196 (plus 45 from both side)
y=98 (divide 2 from both side)
x-y=241
x-98=241
x=339 ( pluse 98 from both side)
So, There are 339 thousand births per day
There are 98 thousand deaths per day
