Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
- BC' = BC×1/2
- BC' = 16×1/2
- BC' = 8
The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
Answer: false
Step-by-step explanation:
The volume of the diamond is 137.1 cm³. The correct option is the last option 137.1 cm³
<h3>Density, Mass and Volume </h3>
From the question, we are to calculate the volume of the diamond
Using the formula,
Density = Mass/ Volume
Then, we can write that
Volume = Mass/ Density
From the given information,
Mass of the large diamond = 481.3 grams (g)
Density of the diamond = 3.51 grams/ centimeters cubed (g/cm³)
Putting the parameters into the formula, we get
Volume = (481.8 g)/ (3.51 g/cm³)
Volume = 137.1225 cm³
Volume ≈ 137.1 cm³
Hence, the volume of the diamond is 137.1 cm³. The correct option is the last option 137.1 cm³
