Step-by-step explanation:
Area= height*base/2
i hope this is correct :)
Answer:
The are 125:9
Step-by-step explanation:
When we know the scale factor
The lengths are related by the scale factor
The areas are related by the scale factor squared
The volumes are related by the scale factor cubed
Since the scale factor is 5:3
Cube each side
5^3: 3^3
125:9
The are 125:9
Answer:
A, C, D
Step-by-step explanation:
When lines are parallel, alternate interior angles at a transversal (5 & 6) are congruent, as are corresponding angles (2 & 3), (2 & 4). The converse is also true: congruent angles mean the lines are parallel.
Angles 2 & 3 are corresponding angles at the transversal <em>r</em> if lines <em>p</em> and <em>q</em> are parallel, so their congruence will guarantee that those lines <em>are</em> parallel. (choice A)
Angles 2 & 4 are corresponding angles at the transversal <em>q</em> if lines <em>r</em> and <em>s</em> are parallel, so their congruence will guarantee that those lines <em>are</em> parallel. (choice C)
Angles 5 & 6 are alternate interior angles at the transversal <em>p</em> if lines <em>r</em> and <em>s</em> are parallel, so their congruence will guarantee that those lines <em>are</em> parallel. (choice D)

Angles 5 and 7 have no common side, so their congruence does not guarantee anything about the lines that create them. Choice B is not applicable.
