No, ΔTSR and ΔQRS cannot be proven congruent by SAS because not enough is information given to prove the triangles congruent by SAS.
What is Congruency?Two figures or objects are congruent if they have the same shape and size.
To prove using SAS congruency we should have at least two congruent side and one congruent angle.
But we don't have the sufficient information.
Hence, ΔTSR and ΔQRS cannot be proven congruent by SAS.

NOTE: Angles not necessarily drawn to scale.
Answer:
60
Step-by-step explanation:
I'm assuming that ED is an exactly straight line, that would mean the angle is 180 degrees. So the sum of the angles in between should also equal 180. This gives you the equation
100 + 20 + x = 180
120 + x = 180
60 = x
3/a times x -4 equals 20
Answer:
a = -5/3
Step-by-step explanation:
3/a × -4 = 20
3a × -4/-4 = 20/-4
3a = -5
a = -5/3
Check:
3/(-5/3) × - 4 = 20
-5 × - 4 = 20

use an exponential expression to calculate the area covered by purple loosestrife seven years from now. is this a valid prediction? What does this result tell you about the constraints on the exponential model?
The area of the wetland that will be covered in purple loosestrife 7 years from now is modeled by this expression 500(1.2)^7
How to illustrate the information?The exponential expression to calculate the area covered by purple loosestrife seven years from now will be:
= 500 × 1.2^7
After evaluating the expression, the model predicts that approximately 1,792 acres of the wetland will be covered in purple loosestrife 7 years from now.
This is not a valid prediction because the total area of the wetland is only 1,240 acres. Therefore, a constraint on the model is that the value of the expression 500(1.2)^t must be less than or equal to 1,240.

20) Find the surface area of the solid shown. 16 dm 17 dm 30 dm
Answer:
680π dm² = 2136.28 dm²
Step-by-step explanation:
Recall:
lateral area of cone = πrs; where s = slant height = 17 dm
area of circle = πr²
lateral area of cylinder = πdh
Lateral area of cone: (3.14159)(8 dm)(17 dm) = 427.26 dm²
Area of base of cylinder: (3.14159)(8 dm)² = 201.06 dm²
Lateral area of cylinder: (3.14159)(16 dm)(30 dm) = 1507.96 dm²
Total surface area = 427.26 dm² + 201.06 dm² + 1507.96 dm²
Total surface area = 680π dm² = 2136.28 dm²
In a binomial experiement, what does it mean to say that each trial is independent of the other trials?.
In a binomial experiment to say that each trial is independent of the other trials means that the outcome of one trial does not affect the other trial.
An experiment with a set number of independent trials and just two results is referred to as a binomial experiment.
To say that in a binomial experiment, each trial is independent of the other trials means that the outcome of one trial does not affect the other trials.

37. For the following exercises, given each set of information, find a linear equation satisfying the conditions, if possible.
37. x-intercept at (-5, 0) and y-intercept at (0, 4)
Answer:
The linear equation for the line with an x-intercept at (-5,0) and y-intercept at (0,4) is found as [tex]$y=\frac{4}{5} x+4$[/tex].
Step-by-step explanation:
A condition is given that a line has an x- intercept at (-5,0) and y- intercept at (0,4).
It is asked to find a linear equation satisfying the given condition.
To do so, first determine the slope of the line using coordinates of the given intercepts. Then write the equation in the slope-intercept form using the slope and the y- intercept.
Step 1 of 2
Determine the slope of the line.
The points of the intercepts of the line are given as (-5,0) and (0,4). Next, the formula for the slope is given as,[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
Substitute 4&0 for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex]respectively, and 0&-5 for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows,
[tex]$$\begin{aligned}m &=\frac{4-0}{0-(-5)} \\m &=\frac{4}{5}\end{aligned}$$[/tex]
Step 2 of 2
Write the equation in the slope-intercept form.
The slope-intercept form of a line is given as follows,
[tex]$$y=m x+b$$[/tex]
The coordinates at the y- intercept is (0,4). Now, as the y- coordinate is 4 , so b=4.
So, substitute 4 for b and [tex]$\frac{4}{5}$[/tex] for m in the equation y=mx+b, as follows,
[tex]$y=\frac{4}{5} x+4$$[/tex]
This is the required linear equation.

y1 = 4 - 4.08693 = -0.08693
y2 = 4 - 4.019376 = -0.019376
y3 = 3.5 - 3.918 = -0.518
y4 = 4 - 3.817 = -0.183
y5 = 3.9 - 3.817 = -0.083
y6 = 3.85 - 3.715 = 0.135
y7 = 4 - 3.682 = 0.318

Hello and Good Morning/Afternoon:
Let's take this problem step-by-step:
First off, let's write the line in point-slope form:
[tex]\rm \hookrightarrow (y-y_0)=m(x-x_0)[/tex]
(x₀, y₀) any random point on the line'm' is the value of the slopeLet's calculate the slope:
[tex]\rm \hookrightarrow Slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
(x₁, y₁): any random point on the line ⇒ (-2, -6)(x₂,y₂): any random point on the line that is not (x₁, y₁) ⇒ (2, -3)[tex]\rm \hookrightarrow slope = \frac{-3--6}{2--2} =\frac{3}{4}[/tex]
Now that we found the slope, let's put it into the point-slope form
⇒ we need (x₀, y₀) ⇒ let's use (2,-3)
[tex](y-(-3))=\frac{3}{4} (x-2)\\y+3=\frac{3}{4} (x-2)[/tex]
The equation, however, could also be put into 'slope-intercept form'
⇒ gotten by isolating the 'y' variable to the left
[tex]y = \frac{3}{4}x-\frac{9}{2}[/tex]
Answer:[tex]y = \frac{3}{4}x-\frac{9}{2}[/tex] or [tex]y+3=\frac{3}{4} (x-2)[/tex]

The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed x Time
Given:
Speed = 5 1/2 miles per hour Time = 2 3/4 hoursSubstituting it in the relationship we get,
Distance = Speed x Time
Distance = 5 1/2 miles per hour x 2 3/4 hours
