C. Yes, the triangles are congruent by SSS.
D. No, the triangles cannot be proven congruent with SSA information.
Answers
Explanation:
Answer:C SSS
Step-by-step explanation:
I got SSS because with the given sides equal, it can be said R is the midpoint of QT therefore QR≈RT and the triangles are congruent by SSS. The theorem used was midpoint theorem

So we know that according to the law of multiplying exponents that when multiplying them, you are just adding them together
With that in mind, x/6+x/8=10
From here, we can just solve for x!
Multiply both sides by 24
4x+3x=240
Add the x’s
7x=240
Anddddd divide both sides by 7
x=240/7
Remember, you can always double check your answer by plugging in your answer into your original equation! :)

Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling
Answers
Answer:
16 meters
Step-by-step explanation:
Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling
The formula to solve for the above question is:
Diagonal² = Width² + Length²
34² = 30² + L²
Collect like terms
L² = 34² - 30²
L = √34² - 30²
L = √(256)
L = 16 meters
Therefore, the length of the ceiling is 16 meters
50 points! Tell whether the orthocenter is inside, on, or outside the triangle. Then find the coordinates of the orthocenter.
Q(-1, 5), R(4, 3), S(-1, -2)
Answers
Answer:
(1,3) is inside the triangleStep-by-step explanation:
Orthocenter is the intersection of altitudes.
We'll calculate the slopes of the two sides and their altitudes ad find the intersection.
Side QRm = (3 - 5)/(4 - (-1)) = -2/5Perpendicular slope:
-1/m = 5/2Perpendicular line passes through S(-1, -2):
y - (-2) = 5/2(x - (-1)) ⇒ y = 5/2x + 1/2Side RSm = (-2 - 3)/(-1 -4) = -5/-5 = 1Perpendicular slope:
-1/m = -1/1 = -1Perpendicular line passes through Q(-1, 5):
y - 5 = -(x - (-1)) ⇒ y = -x + 4The intersection of the two lines is the orthocenter.
Solve the system of equations to get the coordinates of the orthocenter:
5/2x + 1/2 = x + 45x + 1 = -2x + 87x = 7x = 1Find y-coordinate:
y = -1 + 4 = 3The orthocenter is (1, 3)
If we plot the points, we'll see it is inside the triangle

Answers
Answer:
x = -1, y = 0.125
Answer: (-1,1/8)
Step-by-step explanation:
Coordinates are given in (x,y) format. The x axis runs left to right and the y axis runs up and down.
Point P is on -1 of the x axis and appears to be between 0 and .25 on the y axis. This would be half of .25. .25 is 1/4 as a fraction. Half of 1/4 is 1/8. So the coordinates for point P are (-1,1/8)

a sandwich store charges $10 delivery fee and $4.50
b. what is the total cost for x sandwiches ?
Answers
Answer:
Step-by-step explanation:
a sandwich store charges $10 delivery fee and $4.50
b. what is the total cost for x sandwiches ?
total cost equals the cost of the sandwiches plus the delivery fee
one sandwich cost $4.50
x number of sandwiches cost x times $4.50 or $4.50(x)
delivery fee = $10
total cost equals the cost of the sandwiches plus the delivery fee
total cost = $4.50(x) + $10
total cost = $4.50(x) + $10

First find the LCD or least common denominator. The least common denominator is the number that both of the denominators are divisible by.
In this case, 2 and 3 are both divisible by 6.
Convert both fractions into a fraction with a denominator of 6.
1/2 = 3/6 (multiply numerator and denominator by 3)
2/3 = 4/6 (multiply numerator and denominator by 2)
Now you can multiply as they have the same denominator.
3/6 × 4/6 = 12/36
Simplify.
12/36 = 1/3 (numerator and denominator are divisible by 12)

x = 4
Step-by-step explanation:
3x - 5 = 2x -1
Add 5 to both sides
3x - 5 + 5 = 2x - 1 + 5
3x = 2x + 4
Subtract 2x form both Sides
3x - 2x = 2x - 2x + 4
x = 4

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.
Write an equation to represent Steve's situation.
Answers
Answer:
[tex]250 - 20x=y[/tex]
Step-by-step explanation:
As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.
Steve's saving would be equal to his initial value, minus his expense, in essence;
[tex]250 - 20x=y[/tex]
The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.
Answer:
y=250-(20x)
