Answer:
1600
Step-by-step explanation:
Do 400 ÷ 0.25 = 1600
0.25 because of the discount
Check by doing 1600 X 0.25 and it should be 400 which it is
Answer: Y=60x
Step-by-step explanation:
find the slope (Y2-Y1)/(X2-X1)
(240-150)/4-2.5)
90/1.5 =60
It's multiple choice so it can only be a or b. If you do 60 x 2.5 you get 150 so there's no way you will add 480 so you are done it's A. If it's not a multiple choice question then you would do the who y=mx+b and plug in x, y and m and then find the b which in this case would be 0.
Since 30÷15 is 2 you now know each party hat is 2 dollars. Now we know that and we can easily find out how much a roll of streamer is. 11-(4x2)=3. 3÷2=1.5. One roll of streamer is $1.50 and one party hat is $2. I'm pretty sure I did this right lol I hope it helps
You'll need to specify the accuracy to which you want your answer. For example: "Find the volume of this cone to 3 decimal place accuracy."
The formula for the volume of a cone is V = (1/3) (base) (height), where "base" represents the area of the base.
Here the diameter of the base is 24 feet, so the radius of the base is 12 feet.
Thus, the area of the base is (12 feet)^2 times pi: A = 144 pi ft^2.
Multiply this area by the height of the cone, which is 10 feet:
V = 1440 pi ft^3
By calculator, this volume is 4523.893421 cubic feet.
If you want this volume to the nearest cubic foot, it'd be 4524 cubic ft.
If you want this vol. to the nearest 100th cubic ft., it'd be 4523.89 cu. ft.
What is that really supposed to mean
