Positive numbers are always greater than -15. Therefore, it's a greater than.
-2x = - 15
Dividing both sides by -2, we get
x = 7.5
Negative cancels on both sides, so we get a positive equation.
Positive numbers are always greater than -15. Therefore, it's a greater than.
What is greater than or less than?
- Greater than and less than are the comparison symbols.
- When the number is bigger or smaller than the other, then greater than and less than symbols are used.
- If the number is greater than the other, the greater than (>) symbol is used.
- If the number is lesser than the other, the less than the (<) symbol is used.

Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²
Answer:
Horizontal distance between lifeguard and the person is 22 feet.
Step-by-step explanation:
Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.
To find: Horizontal distance between lifeguard and the person.
Solution : If we draw a triangle then tan∅ = 
Here base is the horizontal distance.
Now we put the values in the formula.
tan 34° = 
Or Base = 
= 
So the answer is 22 feet.
