A model car has a length of 7.25 inches. The actual car is 14.5 feet long. What is the scale of the model car?
Answer:
1:24
Step-by-step explanation:
Convert inches to feet, 7.25 inches is 0.604 feet.
0.604:14.5 needs to become 1:something, so set up 0.604/14.5 = 1/x
Solve for x now by dividing 14.5 by 0.604. You get 24 for x, so the answer is 1:24 scale!

Angle A is a supplementary to Angle B. If < b = 65 degrees what is the value of x if < A = 5x -20 ?
Answer:
x = 27
Step-by-step explanation:
Supplementary angles add up to 180 degrees
65 + 5x - 20 = 180
45 +5x = 180
5x = 135
x = 27

It is given that quadrilateral ABCD is a kite. We know that AD ≅ CD by the definition of . By the kite diagonal theorem, AC is to BD This means that angles AED and CED are right angles. We also see that ED ≅ ED by the property. Therefore, we have that ΔAED ≅ ΔCED by .
Answer:
1. kite 2. perpendiclular 3. reflective 4. HL
Step-by-step explanation:
I hope this helps :)
Answer:
We know that AD ≅ CD by the definition of kite. By the kite diagonal theorem, AC is perpendicular to BD. This means that angles AED and CED are right angles. We also see that ED ≅ ED by the reflexive property. Therefore, we have that ΔAED ≅ ΔCED by HL.
Step-by-step explanation:
We know that AD ≅ CD by the definition of kite.
- adjacent sides in a kite are congruent
By the kite diagonal theorem, AC is perpendicular to BD.
- the kite diagonal theorem states that diagonals of a kite form right angles because they are perpendicular to each other.
We also see that ED ≅ ED by the reflexive property.
- any side or angle congruent to itself is identified by the reflexive property
Therefore, we have that ΔAED ≅ ΔCED by HL.
- the triangles formed are all right triangles, so we can they that the two triangles are congruent to each other by the Hypotenuse Leg theorem.

x is on the left side of the < symbol, so the shaded portion of the line will be on the left side of the boundary dot.
The boundary dot is plotted at the constant, which is 1/2 = 2/4. That plot is shown in selection B.

Additional comment
I like to write inequality solutions using the < or ≤ symbols because the relative positions of numbers and variables match their relative positions on the number line. In this problem, we have x < 1/2, so the shaded portion of the line is on the left of the boundary dot, just as x is on the left of 1/2 in the inequality.

Is the temperature measured in Celsius proportional to the temperature measured in Fahrenheit?
Answer:
The relationship between Fahrenheit and Celsius is directly proportional
The relationship between Celsius and Fahrenheit demonstrates that the two units are directly proportional to one another.
Is there a proportional link between the temperature scales?
No. because the ratio is different (no constant of proportionality). The relationship between Celsius and Fahrenheit demonstrates that the two units are directly proportionate to one another. It suggests that as the temperature rises on the Celsius scale, the temperature rises as well on the Fahrenheit scale. Fahrenheit and Celsius have a proportionate relationship. Both follow the various unit differences between each scale and have varying water freezing points. There is one place where the Fahrenheit and Celsius scales meet. At both -40 °C and -40 °F, they are equal. To determine when two temperature scales are equal to one another, the straightforward technique is to set the

(PLEASE HELP) What is the value of x?
Enter your answer in the box.
x =
Answer:
x = 12
Step-by-step explanation:
(10x - 20)° + (6x + 8)°= 180°
(Linear pair angles)
(10x - 20 + 6x + 8)°= 180°
(16x - 12)°= 180°
16x - 12 = 180
16x = 180 + 12
16x = 192
x = 192/16
x = 12
Answer:
so x would equal 12
Step-by-step explanation:
(10x - 20)° + (6x + 8)°= 180°
so you are going to want to combine like terms which would be
10x and 6x, and 20,8
10x+6x=16x
20-8=12
16x-12=180
now you want to get 12 on the opposite side of the equal side so you add (since it is negative) 12 to each side
which gets rid of the first 12
16x=180+12
now you can add 180+12
and you get 192
so now we want to get x by itself in order to do that you must divide
you are going to divide by 16 an each side and the 16 cancels out the first 16
16x/16=192/16
x=192/16
and 192 divided by 16 is 12
so you answer is
x=12
Hope this made sense :)
