Answer:
JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5Step-by-step explanation:
We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.
1. JKLM ~ QRSP
JK : KL : LM : MJ = 20 : 15 : 24 : 25
QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)
The scale factor is 12/20 = 0.6.
__
2. ΔABC ~ ΔUVT
AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6
UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)
The scale factor is 24/16 = 1.5.

∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°Measure of angles for figure 1:
∠1=36∠2=56∠3=124∠4=88∠5=36Measure of angles for figure 2:
∠1=35∠2=145∠3=55∠4=125∠5=55The angle is formed by two rays at a common point of the two rays.
For given figure 1:
∠1+144=180 (Sum of angles on same side of transversal is 180°)
∠1=180-144
∠1=36
∠5+144=180(Sum of angles on a line is 180°)
∠5=180-144
∠5=36
Similarly, ∠3=180-56
∠3=124
∠4+36+56=180(Sum of all angles of a triangle is 180°)
∠4=180-36-56
∠4=88
∠2+36+88=180
∠2=56
Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.
For given, figure 2:
∠1=35(Alternate angle on same side of transversal are equal)
∠2=180-35
∠5=180-35-90(Sum of all angles of a triangle is 180°)
∠5=55
∠4+55=180(Sum of angles on a line is 180°)

Two candles were lit and are burning. Candle A has
an initial height of 10 inches and burning down at a
rate of 1.5 inches per hour. Candle B is burning down
at a rate of 0.5 inches per hour and has an initial
height of 6 inches. Let t represent time in hours and
h represent the total height of the candle.
Answers
Answer:
A - 6 hours and 40 minutes
B - 12 hours
Step-by-step explanation:
Candle A - After 6 hours: the candle will be 1 inch tall, because 6 times 1.5 = 9. You need an extra 40 minutes for the candle to burn completely, because 10/1.5 = 6 and 2/3
Candle B - After 12 hours, the candle will be completely burned, because 6/.5 = 12.
Equation - Initial height/inches burned per hour = time it takes for cnadle to burn down completely
Which conic section is represented by the following equation? 9x^2 – 5x – 3y^2 – 2y + 4 = 0
Answers
Answer:
D. Hyperbola
Step-by-step explanation:
I put B but it was wrong
D is the right answer
The given equation is represent a ''Hyperbola''.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 9x² - 5x - 3y² - 2y + 4 = 0
Now, We know that;
The standard form of the equation is,
⇒ ax² + by² + 2gx + 2fy + 2hxy + c = 0
For Hyperbola, The condition is,
⇒ h² > ab
For Ellipse , The condition is,
⇒ h² < ab
Here, We have;
⇒ h = 0
⇒ a = 9
⇒ b = - 3
⇒ ab = 9 x - 3 = - 27
⇒ h = 0
Hence, We get;
⇒ 0 > - 27
⇒ h² > ab
Thus, This equation is represent a ''Hyperbola''.

A garden table and a bench cost $618 combined. The garden table costs $82 less than the bench. What is the cost of the bench?
Answers
Answer:
268
Step-by-step explanation:
If a garden table and a bench cost $618 combined. The garden table costs $82 less than the bench then the cost of the bench is $350.
Let's denote the cost of the bench as "x."
According to the given information, the garden table costs $82 less than the bench, so its cost can be represented as "x - 82."
The total cost of the garden table and bench combined is $618. Therefore, we can set up the following equation:
x + (x - 82) = 618
Simplifying the equation:
2x - 82 = 618
Next, we isolate the term with "x" by adding 82 to both sides of the equation:
2x - 82 + 82 = 618 + 82
2x = 700
Divide both sides by 2:
x=350
Therefore, the cost of the bench is $350.

5. Solve the equation - 4(x - 1) + 6x = 2(17 -- x) for x.
Answers
Answer:
x = 15/2 or 7.5
Step-by-step explanation:
-4 (x - 1) + 6x = 2(17 - x)
First, distribute the -4 and 2, and remember that multiplying two negatives make a positive.
-4x + 4 + 6x = 34 - 2x
Combine like terms
2x + 4 = 34 - 2x
Subtract 4 from both sides
2x = 30 - 2x
Add 2x to both sides
4x = 30
Finally, divide both sides by 4
x = 15/2 or 7.5
