Answer:
A) x=46
Step-by-step explanation:
The triangles are congruent, which means the angles are congruent as well. Therefore, we can set angles ADC and ABC equal to each other to solve for x:
100=2x+8
92=2x
46=x
Therefore, A is correct
Answer:
The light intensity at a depth of 24 feet is 3.0143 lumens.
The light intensity will be 7 lumenus at the depth of 9.3732 feet approximately.
Step-by-step explanation:
Consider the provided formula.

Where I is the intensity of light and x is the depth.
Part (A) Find the light intensity at a depth of 24 feet.
Substitute x=24 in above formula.





Hence, the light intensity at a depth of 24 feet is 3.0143 lumens.
Part (B) At what depth is the light intensity 7 lumens
Substitute I=7 in above formula.





Hence, the light intensity will be 7 lumenus at the depth of 9.3732 feet approximately.
False.
The volume of a cylinder is how much space it takes up INSIDE. You would use volume to measure how much you can put something inside (like water)
Surface area measures the OUTSIDE of a shape. In this case, you'd use surface area to determine how much paper he needs.

Answer:
x = 1.5; 20x + 5 = 35; 24x + 1 = 37;
Step-by-step explanation:
______________________________
1) 20x + 5 = 24x - 1
2) 20x + 6 = 24x
3) 6 = 4x
4) x = 1.5
_______________________________
20x + 5
1) 20(1.5) + 5
2) 30 + 5
3) 35
_______________________________
24x + 1
1) 24(1.5) + 1
2) 36 + 1
3) 37
