Answer:
About 90%
Step-by-step explanation:
If the cup was filled at a constant rate, then the cup fills at 70/2=35 cubic centimeters per second. The formula for the volume of a cone is 
, or in this case 
cubic centimeters. After 3 seconds, the cup would have 35*3=105 cubic centimeters of water inside of it, or about 89.52% which rounds to 90%. Hope this helps!

For Q1 and Q2
For Q3 and Q4
Correct the answer is -55
Answer:
a
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Rearrange 3x - y = 4 into this form ( add y to both sides )
3x = y + 4 ( subtract 4 from both sides )
3x - 4 = y OR y = 3x - 4 → a
Answer: y=-(1/8)x+(21/2)
Explanation:
The new equation’s slope needs to be perpendicular to y=8x-1
To get the new slope, we take the negative reciprocal of the slope from above
8 —> -1/8
Now we have y=-(1/8)x+b but it needs to pass through (4,10), so we need to find the value of b that makes this possible.
Since (4,10) is in the form of (x,y) we can plug in these values into the new equation to solve for b:
y=-(1/8)x+b
10=-(1/8)4+b
10=(-1/2)+b
b=(21/2)
Now put b back into the new equation
y=-(1/8)x+b
y=-(1/8)x+(21/2)
