Answer:
80 * 80% = 64 So it's not A
80 * 55% = 44 so it's not B
80 * 100% = 80 so it's not C
80 * 125% = 100 so D is your answer
Step-by-step explanation:
Answer:
Part A: A(m(t)) = π(81t²); Part B: 1017.36
Step by step explanation:
Part A:
To find A(m(t)), we substitute our value for m(t), 9t, in place of m:
A(m(t)) = πm² = π(9t)² = π(81t²)
A(m(t)) = π(81t²)
Part B:
Substitute 2 in for t:
A(m(2)) = π(81(2²)) = π(81(4)) = 3.14(324) = 1017.36
It would probably be x= 20 ×7
Answer:
Step-by-step explanation:
(1,2) ; (3,2)
slope = y₂ - y₁ / x₂ - x₁
= ( 2-2 )/( 3 - 1) = 0
So, the line is parallel to x-axis and its slope is 0
For this case we propose a rule of three. We assume that the excess water received was in one day. So:
cup ------> 100%
x ----------------------------> 25%
Where "x" represents excess water.
Thus, the excess water is 
cups.
Then, in one day you receive in total:
cups of water.
Answer:
cups of water
