Answer:
The age of Jenny's mom is 40 % of age of Jenny's great-grandmother. (Input: 40)
Step-by-step explanation:
The percentage needed is calculated by the following expression:
Where:
- Percentage of Jenny's mother with respect to Jenny's great-grandmother, measured in percentage.
- Age of Jenny's mother, measured in years.
- Age of Jenny's great-grandmother, measured in years.
If we know that 
and 
, the percentage is:
The age of Jenny's mom is 40 % of age of Jenny's great-grandmother.

Step-by-step explanation:
Acute angle
Answer:
When point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).
i.e A'(0, 1) is the image of point A after a reflection.
Hence, point A is reflected across the x-axis.
Step-by-step explanation:
When we reflect a point A across the x-axis, the value of 'y' gets negated, but the value of 'x' remains unchanged.
In other words, when point P with coordinates (x, y) is reflected across the x-axis and mapped onto point P', the coordinates of P' will be (x, -y).
Thus, the rule is:
P(x, y) → P'(x, -y)
Thus, when point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).
i.e A'(0, 1) is the image of point A after a reflection.
Hence, point A is reflected across the x-axis.

Answer:
D) 4
Step-by-step explanation:
By remote interior angle property if a triangle, we have:
19x° + (18x - 4)° = 144°
(18x - 4 + 19x)° = 144°
(37x - 4)° = 144°
37x - 4 = 144
37x = 144 + 4
37x = 148
x = 148/37
x = 4
