Answer: This is a nonfunction because there are two different x values for the y value of 20 . In order for it to be functional every x value has to have a different y value.
Step-by-step explanation:
1st Question:
the answer is 85 because the angle measure does not change even if you rotate the figure.
2nd Question:
The answer is A) reflection across y-axis and translation 7 units down
3rd Question:
The first answer choice is correct because the figure increases/decreases in length on all side lengths and the angle measures stay the same.
Question 10: (on the test online)
The answer is 12*6 or 72 because 30 (a'b') / 5 (ab) is 6 giving you the scale factor for the dilation.
Question 11:
The answer is a dilation
Question 12:
The answer is a dilation and a translation because you first increase the size of the figure then move it down and to the right.
This can be treated as a proportion problem.
Larger solid:
Surface area = 1,372 cm²
Volume = 1,801 cm³
Smaller solid:
Surface area = 1,008cm²
Volume = ?
1,372 / 1,801 = 1008 / x
1,372 * x = 1,801 * 1008
1,372x = 1,815,408
x = 1,815,408 / 1,372
x = 1,323.18
The volume of the smaller solid is 1,323.18 cm³
Answer : A
The word "increased" indicates a plus sign. The word "is equal" helps show us show that something is = to 15
Answer:
1/2
Step-by-step explanation:
1/2 means one half. 50% is a half of a whole. I hope I helped :)
