Answer:

Step-by-step explanation:
In order to find which expression is equivalent to
, we need to note the order of operations.
PEMDAS tells us that when solving an equation, we'd go in this order.
<em>P</em><em>arentheses</em>
<em>E</em><em>xponents</em>
<em>M</em><em>ultiplication/</em><em>D</em><em>ivision</em>
<em>A</em><em>ddition/</em><em>S</em><em>ubtraction</em>
Using this, we'd start by evaluating what's inside the parentheses,
. We'd then bring that value to the 0th power.
<em>Wait...</em> there's something special about bringing anything to the 0th power. Bringing anything to the 0th power makes the value 1.
It can be -5... it can be 1,000,000, any number possible, taken to the 0th power, will always be 1.
So no matter what the value inside the parentheses is, taking it to the 0th power will <u>always make it 1</u>.
Therefore, this expression is equivalent to 1.
Hope this helped!
Answer: After 5 minutes, the plane is at 20,000 feet. It descended a total of 10,000 feet.
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000
Answer:

C + d = d + c
what u have here is the commutative property of addition which simply states that u can commute ur numbers (move them around) and it does not change the outcome
Answer:
Step-by-step explanation:
Multiply it by 0.75, or find 3/4 of that number. Whichever you prefer! The first one always works though the second one sometimes does but sometimes 3/4 of the number isn't that obvious.
