Answer:
The total percent decrease is 
Step-by-step explanation:
- We are given with a word problem
- We are asked to find the total percentage decrease
- We can do this in two steps
Step 1: Finding the two percentage decrease
Step 2: Finding their difference
Step 1 of 2
Let the decrease by a% be 100-a
Then b% decrease is
Step 2 of 2
The percentage difference between the two percentages is,
Since 100 is the total percent is the percentage decrease.
All you need to do for this is 155-75 which would be 80 :) hope this helps
Find a and b to the nearest integer↑
Answer: V = 100.48
Step-by-step explanation:
To get this value, you need to know the formula of the volume of the cone, which is:
V = π*r^2*h / 3
Where:
r: cone radius
h: height
π: value of pi which is 3.14
Now the radius, is half the diameter of base of the cone so:
r = 8 / 2 = 4 units
Now we have all the data needed to get the volume of the cone, let's use the expression given above:
V = 3.14 * (4)^2 * 6 / 3
V = 3.14 * 16 * 6 / 3
V = 301.44 / 3
V = 100.48
Answer:
y = 4/3x - 3
Step-by-step explanation:
Use this formula to find the slope first.
(y2 - y1) / (x2 - x1)
(x2, y2) --> (-3, -7)
(x1, y1) ---> (3, 1)
Now plug in:
(-7 - 1) / (-3 - 3) = -8 / -6 = 4/3
Now find the y intercept by plugging any points to y= 4/3x + b
I will use (3, 1).
1 = 4/3(3) + b
1 = 4 + b (subtract 4 on both sides)
-3 = b
So the formula is
y = 4/3x - 3
