Answer:
-60% decrease
Step-by-step explanation:
60 is the old value and 24 is the new value.
percent change = x 100%
so for this problem, you can substitute the values given in the formula:
percent change = x 100% = x 100% =
-60% (decrease)
what that guy said ddddddddddddddddd
The height on the wall a 15-foot ladder will reach if it is placed 3. 5 feet from the base of a wall is 14.6 feet.
Using Pythagoras theorem,
c² = a² + b²
where
c = hypotenuse
a and b are the other two legs
The ladder length represent the hypotenuse sides
The distance of the ladder to the base of the wall is one of the leg.
The height on the wall the 15 ft ladder reach is the other leg
Therefore,
a² = 15² - 3.5²
a² = 225 - 12.25
a = √212.75
a = 14.5859521458
a ≈ 14.6 feet

Answer:
-2 + 6!
Step-by-step explanation:
Since the last two are negatives back to back, you change them to positive to make the problem easier! Anytime the last two signs are back to back negatives, you can do that, but never change the first sign!
I hope this helps!!
