These questions are SOOO easy, but I just don't have a clue. (don't even know if they technically are algebra they are that easy).
x² - 8x - 20 =
(x+10) (x-2)
Thats what I got for that answer (lucky guess) but how do you know which side each sign goes on.. ie (x+10)(x-2) or (x+2) (x-10)??
Same problem with this question...
(x-6) (x-5) =
x² - 11x + 30
Answer. 2(x-4)
Step-by-step explanation:
common factor
2x-8
2(x-4)
The parent volunteers:
120 snow cones ... 5 hours
x snow cones = ? ... 1 hour
120 * 1 = 5 * x
120 = 5 * x /5
x = 120 / 5 = 24 snow cones
The student council:
100 snow cones ... 4 hours
y snow cones = ? ... 1 hour
100 * 1 = 4 * y
100 = 4 * y /4
y = 100 / 4 = 25 snow cones
Result: The student council made more snow cones per hour (25 > 24).
Answer:
6433.98 ft
Step-by-step explanation:
In order to find what 25% of the tank's capacity is, we know to know the full capacity of the tank then take 25% of that. The volume formula for a right circular cone is
We have all the values we need for that:
This gives us a volume of 25735.93 cubic feet total.
25% of that:
.25 × 25735.93 = 6433.98 ft
Since p=24 and to get p you do 3w+3w+w+w which equals 8w=24 and 24/8 is 3 so your answer is 3
