Which diagram shows an obtuse scalene triangle?
Option D. is an obtuse scalene triangle in the given lists of diagrams.
What is obtuse scalene triangle?In terms of geometry, an obtuse scalene triangle is one in which one of the angles is less than 90 degrees and the other two are less than 180 degrees, with the one angle measuring greater than 90 degrees but less than 180 degrees. Measurement differences exist for each of the three sides and angles.
Both the obtuse triangle and the scalene triangle's characteristics are present in an obtuse scalene triangle. A scalene triangle has all three sides and angles that are of a different size, whereas an obtuse triangle only has one obtuse angle. The following are the characteristics of an obtuse scalene triangle:
Two of its angles are acute, while the other is obtuse.Measurement varies across all sides and angles.Three interior angles added together result in a 180° angle.Learn more about obtuse triangle

What is a contingency table?A contingency table is a matrix-form table that shows how often different combinations of variables appear.
It's really popular in survey research, business intelligence, engineering, and scientific research. Basically, a contingency table with 10 rows and 11 columns has 90 degrees of freedom.
They are also sometimes known as two-way frequency tables and are used to show how often different combinations of variables occur.
A contingency table gives you an idea of how two variables relate to each other.
It displays one categorical variable along the rows and another categorical variable along the columns. It can help point out any interactions between them.
Therefore, essentially, a table with 10 rows and 11 columns has (D) 90 degrees of freedom.

Meri is making birdhouses. Each birdhouse uses 58 yard of wood. What is the total length of wood Meri will need to make 12 birdhouses? Drag each of the numbers from the box to complete and solve the equation. Each number will be used once
Meri will need 696 yards of wood to make 12 birdhouses, as each birdhouse requires 58 yards of wood.
Meri is making birdhouses and each birdhouse needs 58 yards of wood. To find out the total length of wood needed for making 12 birdhouses, we can use the formula:
length of wood per birdhouse x number of birdhouses = total length of wood
So, in this case, we can substitute the given values in the formula:
58 yards x 12 birdhouses = 696 yards
This means Meri needs 696 yards of wood to make 12 birdhouses.
This equation works because it uses the concept of the unitary method, where we find the total length of wood by multiplying the number of birdhouses by the length of wood used in each birdhouse, this way we are able to find the total amount of wood needed.

If Ahmad took 200 mg of medication and the function [tex]f(t) = 200e^{-0.4t}[/tex] can be used to determine the amount of medication, then He will have only 50 mg of medication left in his system after (c) 3.47 hours .
The Function that is used to determine the amount of medication, f(t), still in his system after t hours. is given as [tex]f(t) = 200e^{-0.4t}[/tex] ,
we have to find the after how many hours there will be only 50 mg of medication left ;
we need to substitute f(t) as 50 ;
we get ;
⇒ [tex]50 = 200e^{-0.4t}[/tex] ;
⇒ [tex]\frac{50}{200} =e^{-0.4t}[/tex] ;
⇒ [tex]\frac{1}{4} =e^{-0.4t}[/tex]
On solving further ,
we get ;
⇒ [tex]t=3.4657..[/tex] hours ;
So , t≈ 3.47 hours .
Therefore , After 3.47 hours there will be 50 mg of medication left .

Kevin wants to build a dartboard. The dartboard consists of two
circles centred at O and three shaded regions as in the diagram.
The diameters BOD and AOC are perpendicular to each other.
Given OE= ED = 10 cm. Calculate the area of the shaded regions
22
in cm². ((Use π= 22/7))
Answer:
Step-by-step explanation:
strategy: Find the area of the entire dartboard, then subtracted the inner circle from that whole. we will have the entire outer circle, so divide that by 2 for half of it. Next divide the inner circle by 4 . Then add that to the outer circle answer from above.
whole circle = [tex]\pi[/tex]*[tex]20^{2}[/tex] = 1257.142857 [tex]cm^{2}[/tex]
inner circle = [tex]\pi[/tex]*[tex]10^{2}[/tex] = 314.2857143 [tex]cm^{2}[/tex]
1257.142857 - 314.2857143 = 942.8571427 outer circle
942.8571427 / 2 = 471.4285 ( half of the outer circle)
now find quarter of the inner circle
314.2857143 / 4 = 78.57142855
add the two parts together
78.57142855 + 471.4285 = 549.9999

Olving ytem of linear equation in two variable
1. 4x8y=24 2. 2xy=19 3. 3x2y=15
4x2y=12 x-y=11 x2y=10
The solution of this system of linear equations is x=3, y=-5.
To solve this system of linear equations, you can use various methods such as substitution, elimination, or matrices. Here is one way to solve using the substitution method:
From equation 2, we can find the value of x in terms of y: x = (11+y)/2Substitute this value of x into equations 1 and 3:4((11+y)/2) + 8y = 24
3((11+y)/2) + 2y = 15
Solve for y in the first equation: 8y = 24 - 44 = -20y = -5
Substitute this value of y back into equation 2 to find x:x = (11 + (-5))/2
x = 3
Substitute the values of x and y back into the original equations to check if they are correct:4(3) + 8(-5) = 24
3(3) + 2(-5) = 15

Answer:
x = 3.5
Step-by-step explanation:
Each value is multiplied by 1.5 so 7 times 1.5 is 10.5
10.5/3 = 3.5
Answer:
1.5
Step-by-step explanation:
To find the value of x that makes triangle DEF similar to XYZ, we have to find the scale. To do this find 2 similar sides. I chose 7.5 from XYZ and 5 from DEF. Divide 7.5 by 5 to get 1.5. 1.5 is our scale so this means we will insert 1.5 for x and get 4.5 as our answer.

if the center of a circle is (-5, -8) and contains the point (16, 68) what is the equation ?
Answer:
[tex](x+5)^2+(y+8)^2=6217[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius
1) Plug the center of the circle into the equation
Center: (-5,-8)
[tex](x-h)^2+(y-k)^2=r^2\\(x-(-5))^2+(y-(-8))^2=r^2\\(x+5)^2+(y+8)^2=r^2[/tex]
2) Determine r²
Plug in the given point (16,68)
[tex](x+5)^2+(y+8)^2=r^2\\(16+5)^2+(68+8)^2=r^2\\(21)^2+(76)^2=r^2\\441+5776=r^2\\6217=r^2[/tex]
Therefore, r² is equal to 6217. Plug this back into [tex](x+5)^2+(y+8)^2=r^2[/tex]:
[tex](x+5)^2+(y+8)^2=6217[/tex]

An amusement park has a collection of scale models, with ratio 1:20, of buildings and other sights from around the country. The height of the United States Capitol is 289 feet. What is the height in feet of its replica at this park, rounded to the nearest whole number
The height in feet of its replica at this park, rounded to the nearest whole number is 14 feet.
What connection exists between height and separation?Distance is the measurement of an object's horizontal distance from a specific location, whereas height is the measurement of an object's height in the vertical direction.
Since the heights of real buildings are 1:10 times higher than those of model buildings, this is evident. We also know that the actual height of the US Capitol is 289 feet, so we divide that figure by 20 to determine the model's height. That amounts to 14.45, rounding to 14. Thus, the duplicate is 14 feet, rounded up to the nearest whole number.

Examples of negation are ,
The negation of P is ∼P.The negation of A ^ B^ C is ∼( A ^ B ^ C ).The negation of A is ∼( A ).The negation of Y ^ VB is ∼( Y ^ VB ).The negation of 6 ^ 7is ∼( 6 ^ 7).Logical operations are performed to check the trueness of an expression.
These are generally Boolean expressions or algebraic functions.
A negation of a basic assertion is made by inserting the word "not" into the original statement. The truth value of the negation will always be the inverse of the truth value of the original assertion.

The graphs of lines f an g are shown on the grid. Write a system of equations to represent this graph.
The Equation of line F is y= -9/2x + 59/2.
The Equation of line G is y = 1/10 x .
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
For Line F:
slope = -9 /2
and, Equation of line F as
y - (-2) = -9/2 (x -(7))
y + 2= -9/2( x- 7)
y = -9/2x + 63/2 -2
y= -9/2x + 59/2
For Line G:
Slope = (0 -(1))/ ( 0-(10))
slope = 1/10

y - (1) = 1/10 (x -10)
y-1 = 1/10 x - 1
