Answer:
A.The scale factor is 0.25 ⇒ <u>True</u>
B.The scale factor is 4 ⇒ <u>False</u>
Step-by-step explanation:
<u>See the attached figure.</u>
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
A dilation that creates a smaller image is called a reduction.
As Shown, two right triangles, The first triangle is dilated to form the second triangle.
We can deduce that the second image is a smaller than the first triangle.
The hypotenuse of the first triangle = 4.4
The hypotenuse of the second triangle = 1.1
So, the scale factor = 1.1/4.4 = 11/44 = 1/4 = 0.25
<u>We will check the options:</u>
A.The scale factor is 0.25 ⇒ True
B.The scale factor is 4 ⇒ False
Answer:
A. T = 20°C - (2.8°C/h × 4h)
Step-by-step explanation:
The rate of change of temperature (-2.8°C/h) is multiplied by time (4h) to get the change in temperature (-11.2°C). That change is added to the initial temperature (20°C) to find the temperature after 4 hours.
Only equation A properly expresses this calculation.
In choice B, the rate of change is (wrongly) shown as +2.8°C/h. In the other choices, the combinations of units are nonsense. (What is a °C·h?)
The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10 18-10=8 There is two sides so you do eight divided by two
The length is 4
Hello.
<span>Reorder the terms:
-6 + y = 4(x + 5)
Reorder the terms:
-6 + y = 4(5 + x)
-6 + y = (5 * 4 + x * 4)
-6 + y = (20 + 4x)
Solving
-6 + y = 20 + 4x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + y = 20 + 6 + 4x
Combine like terms: -6 + 6 = 0
0 + y = 20 + 6 + 4x
y = 20 + 6 + 4x
Combine like terms: 20 + 6 = 26
y = 26 + 4x
Simplifying
y = 26 + 4x
