<h3>Answer: 80</h3>
====================================================
Explanation:
There are probably many approaches here, but one way to do this is to extend segment DO to form a line. Check out the diagram below. This line is in red.
The goal is to have this line extend to intersect with line AB. Let's call this intersection point E.
In that diagram, I've marked the variable y as angle EOB. Notice that angles BEO and CDO are congruent alternate interior angles (since lines AB and CD are parallel). So that's where that extra 30 degree angle comes from.
Focus on triangle EOB. The three angles of any triangle always add to 180
E+O+B = 180
30+y+50 = 180
y+80 = 180
y = 180-80
y = 100
The last step is to solve the equation below for x
x+y = 180
x+100 = 180
x = 180-100
x = 80
This works because angles x and y are supplementary. They form a straight angle.

Answer:
a)
b) 334,858 bacteria
c) 4.67 hours
d) 2 hours
Step-by-step explanation:
a) Initial number of bacteria is the coefficient, that is, 250. And the growth rate is the coefficient besides “t”: 0.15. It’s rate of growth because of its positive sign; when it’s negative, it’s taken as rate of decay.
Another way to see that is the following:
Initial number of bacteria is N(0), which implies . And
. The process is:
b) After 2 days means . So, we just replace and operate:
c)
d)
Given Information:
Monthly payment = MP = $1500/4 = $375
Monthly interest rate = r = 25/12 = 2.083%
Required Information:
Present Value = ?
Answer:
Explanation:
n = 10*4
n = 40 monthly payments
The present value is found by
Where r is monthly interest rate.
MP is the monthly payment.
Therefore, $10,110 is the present value of 10 quarterly payments of $1500 each at 25% interest rate compounded each month.
