Answer:
Let x = the age of the youngest child
Let x + 1 = the age of the middle child
Let x + 2 = the age of the oldest child
x + x + 1 + x + 2 = 39
3x + 3 = 39
3x = 36
x = 12 years
Solution:
The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes.
On analysing the graph ,
This table shows how the volume, V, of the cube changes as the length of the sides, S, changes.
Option C is the correct option for the table that matches the graph.
Step-by-step explanation:
Suppose AB is the 3- foot high access ramp that ends at point C 20 feet along the ground and
theta is the angle of depression from the start of 3 foot high ramp at point A
Now, in ∆ ABC
m<ACB= theta ( alternate interior angle)
Therefore,
(theta) = tan⁻¹(3/20)
= 8.5°
I’d say A: congruent by SSS because the sides are labeled as equal and they share the other side.
