Consider the picture, and check the choices:
A. The alternate interior angles, are also called Z angles, because of the Z shape they create.
examples of Z angles, are the green angles and purple angles shown in the picture.
They really look identical (congruent)
B.
No: check the green angles in figure 1, and purple angles if figure 2. they are not acute.
C.
No. In each case, we have the same number of acute angles and obtuse angles,
except case3, where the intersecting line, is perpendicular to the parallel lines.
D.
No, by the same reasoning used in part C. Only when the intersecting line cuts the 2 parallel lines perpendicularly, all the angles are congruent.
Answer: A
Why not start out by writing a linear relationship for the plant height?
h(m) = 10 + 3m, where h is the height in mm and m is the time in years, starting from zero (0).
After 8 months, the plant height is h(8) = 10 mm + 3(8) mm, or 34 mm.
After 3 years (36 months), the plant ht. is h(36) = 118 mm.
Before:
The number of goats =60%
The number of cows = 100%
Using ratio
Cows : Goats
60 : 100 reduced to simplest term
C:G
3:5
After
The number of cows = 100%
The number of goats = 60%
Using ratio
C:G
100:60 reduced to simplest term
C:G
5:3
Number of cows remained constant. Therefore find the common multiple.
Before
C:G
15:25
After
C:G
15:9
Find the difference in the units of goats
(a)25 - 19= 16
16 units =80
1 unit = 5
15 units (cows) = 5 x 15 = 75
There were 75 cows.
(B)
Number of goats at first
25 units = 5 x 25 = 125
Therefore percentage= 80/125 x 100
= 64%
Answer:
B. 4 7/8 x 5 x 12 1/2
Step-by-step explanation:
volume = L x H x W
First note that 10 2/3 feet equate 127.2 inches.
Denote by x the distance we are looking for.
We have the following equation:

Solving the above equation for x we get:
The distance is 25.7 inches.
