550+450-120+720=1,600
720/1,600*100%
=720/160%
=45%
therefore, 45% of new balance
Answer:
<h2>D.
240 strands of bacteria</h2>
Step-by-step explanation:
Given a population culture modeled by the equation P(t) = 15(2)^t/4,
If the population culture begins with 15 strands of bacteria, at t = 0sec, P(t) = 15
if the population doubles after 4hours, this means a t = 4hrs, P(t) =2 * 15 = 30strands
We are to get P(t) when t = 16hours. Substituting t = 16 into the modeled equation we have;
P(16) = 15(2)^16/4
P(16) = 15(2)^4
P(16) = 15(16)
P(16) = 240 strands of bacteria.
Answer:
Solving for x gives x=7
Step-by-step explanation:
First lets rewrite our equation clear, which from the question reads as :
Eqn(1).
This is a case of an equation with one variable <em>(i.e. one uknown)</em> denoted as .
The question is asking as to solve this equation and obtain the value of .
To do so we start by rewriting and simplifying the equation as follow:
which is the same as
Here we have a fraction on the left hand side reading as and an integer on the right hand side as . Thus we move the denominator of the fraction, in this case to the right hand side where we multiply it with , to eliminate our fraction and solve for as follow:
(Note how we transferd from the left hand side to the right hand side, the sign changed from <em>negative </em>to <em>positive). </em>
Answer:
84
Step-by-step explanation:
140% of 60 = 60 times 140% = 60 × 1.4 = 84
