Answer:
1/5
Step-by-step explanation:
The stick has a length of 5 units
The stick is broken at two points chosen at random
First break: the probability that you get a piece that is 1 unit or longer than 1 units= 1/5.
Second break, the probability that you get a piece that is 1 unit or longer than 1 units is 1/5.
Therefore,
The total probability =probability of first break * probability of second break * original stick unit
=1/5 * 1/5 * 5
= 1/25 *5
=5/25
=1/5
Answer: 10m+2
Explanation: perimeter = all the sides added together. Then simplify it. :)

Sorry, I'm on the road and couldn't take a picture of the solution
Answer:
a⁻³⁵
Step-by-step explanation:
((a²)⁻²)⁵ ÷ (a⁴a)³
((a²)⁻²)⁵ ÷ (a⁴a¹)³
= (a⁻⁴)⁵ ÷ (a⁵)³
= a⁻²⁰ ÷ a¹⁵
= a⁻²⁰⁻¹⁵
= a⁻³⁵
Exponent rules:
Multiplying two numbers with same base: add exponents
Dividing two numbers with same base: subtract exponents
Number with exponent raised to another exponent: multiply the exponents together
