a. 45
0.90
b. 40
d. 80
Please select the best answer from the choices provided

Jessica's annual salary decreased by 3800, which was a 9% decrease. what was Jessica's original salary?
Answers
Answer:
Step-by-step explanation:
x = original salary
$3800 = (1-9%)x = (1-0.09)x = 0.91x
x = $3800/0.91 = $4175.82
The original annual salary of Jessica is 42222
Let the original annual salary of Jessica be represented by x.
Percentage decrease in salary = 9%
Amount of the decrease = 3800
Therefore, based on the information given, the equation to solve the question will be:
9% × x = 3800
0.09 × x = 3800
0.09x = 3800
Divide both side by 0.09
0.09x/0.09 = 3800/0.09
x = 42222
Therefore, the original annual salary of Jessica is 42222.

If a woman making $37,000 a year receives a cost-of-living increase of 2.4%, what will her new salary be?
Answers
Answer: $37,888
Step-by-step explanation:
2.4% of 37,000 is 888.
37,000 + 888 = 37,888.
=$37,888
Her new salary will be $37,888.
What is cost-of-living?
“Cost of living” exists as the amount of money you require to sustain a certain lifestyle in a disseminated place. Because the price of goods and services differs from one city to the next, calculating the cost of living will determine how reasonable it exists to live in a certain area.
increased cost of living would be :
2.4% of 37,000 = 2.4/100 X 37,000 = 888
therefore, new salary would be :
37,000 + 888 = 37,888.

A certain radioactive material is known to decay at a rate proportional to the amount present. If initially there is 50 mg/L of the material present and after 2 hours it is observed that the material has lost 10 percent of its original concentration, find (a) an expression for the concentration of the material remaining at any time.
Answers
Answer:
[tex]Q(t) = 50e^{-0.0527t}[/tex]
Step-by-step explanation:
A certain radioactive material is known to decay at a rate proportional to the amount present.
This means that the situation can be described by the following differential equation:
[tex]\frac{dQ}{dt} = -rQ[/tex]
In which r is the decay rate.
Solving the differential equation by separation of variables, we have that:
[tex]\frac{dQ}{Q} = -r dt[/tex]
Integrating both sides:
[tex]\ln{Q} = -rt + K[/tex]
In which K is the integrative constant.
Applying the exponential to both sides, to remove the ln, we get:
[tex]Q(t) = Ke^{-rt}[/tex]
In which K is the initial amount present.
Initially there is 50 mg/L
This means that [tex]K = 50[/tex].
After 2 hours it is observed that the material has lost 10 percent of its original concentration
This means that [tex]Q(2) = 0.9K[/tex]. So
[tex]0.9K = Ke^{-2r}[/tex]
[tex]e^{-2r} = 0.9[/tex]
[tex]\ln{e^{-2r}} = \ln{0.9}[/tex]
[tex]-2r = \ln{0.9}[/tex]
[tex]r = -\frac{\ln{0.9}}{2}[/tex]
[tex]r = 0.0527[/tex]
So
[tex]Q(t) = Ke^{-rt}[/tex]
[tex]Q(t) = 50e^{-0.0527t}[/tex]
Refer to the following formula for expected payoff:
Expected payoff= (Probability Of rival matching x Loss from price cut) + (Probability Of rival not matching x Gain from price cut)
Suppose the payoff for each Of four strategic interactions is as follows:
Rival Response

Reduce Price Loss=$800 Gain= $50,000
Don't Reduce Price Loss=$6000 No loss or gain
Required:
a. If the probability of rivals matching a price reduction is 98 percent, what is the expected payoff of a price cut?
b. If the probability of rivals reducing price even though you don't is 5 percent, what is the expected payoff Of not reducing price?
b. If the probability of rivals reducing price even though you don't is 5 percent, what is the expected payoff of not reducing price?
c. Based on your answers to (a) and (b), should the firm Cut its price?
Can't determine from the information given
Yes
No
Answers
Answer:
Step-by-step explanation:
From the given information:
The price reduction = 98% = 0.98
[tex]Then \ the \ expected \ payoff \ = \[(probability \ of \ matching \ price \ reduction \ * \ size \ of \ loss \ from \ price \ cuts \ ) \ + \ ( \ probability \ o f \ rivals\ not \ matching \ * \ gain \ from \ price \ cuts )][/tex]
where;
P(rival not matching ) = (100 - 98)% = 2%
P(rival not matching ) = 0.02
The expected payoff = [(0.98 * -800) + (0.02*50000)]
The expected payoff = [( -784+ 1000)]
The expected payoff = 216
(b) Probability of rivals reducing price = 5%
= 5/100
= 0.05
∴
Probability of rivals reducing price = 1 - 0.05 = 0.95
The expected payoff = (0.05 * -6000) + (0.95 *0)
The expected payoff = -300 + 0
The expected payoff = -300
(c) Yes.
Based on answers (a) and (b), the firm should cut the price.

Cherylis making candy bags for her friends. She has a bag of candy that has 20 pieces and a bag of candy that has 15 pieces. If she is making candy bags for 5 friends, how many pieces of candy, c, will each friend receive?
Answers
Answer:
Each friend will receive 7 candies.
Step-by-step explanation:
Given that:
Number of candies in one bag = 20 pieces
Number of candies in other bag = 15 pieces
Total number of candies = 20 + 15 = 35 pieces
Number of friends = 5
Let,
c be the number of candies each friend will receive.
5c = 35
Dividing both sides by 5
[tex]\frac{5c}{5}=\frac{35}{5}[/tex]
c = 7
Hence,
Each friend will receive 7 candies.

Answer:C. The value of the series is equal to the value of the 1st or 24th numbers in the series.
Step-by-step explanation:
The given series is .
To find the first term of this series, we substitute k=1 to obtain:
To find the 24th term of the series, we put k=24 to get:
The value of the series is the sum of all the terms in the series.
We can find the value of the series using the formula:
.
In this case, the last term is .
.
.
.
Now let us analyse the options:
A. The value of the series is greater than the value of the 24th number in the series.
False: because 6 is not greater than 6.
B. The value of the series is between the values of the 1st and 24th numbers in the series.
False: because 6 is not between -5.5 and 6
C. The value of the series is equal to the value of the 1st or 24th numbers in the series.
True: In logics, an "or" statement (disjunction) is true if one of the alternatives is true. In this case the sum of the series is equal to the 24th number of the series because 6=6 is true
D. The value of the series is less than the value of the 1st number in the series.
False: because 6 is not less than -5.5

What is the value of x

Answer:
x = 10
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation ...
Sin = Opposite/Hypotenuse
sin(30°) = 5/x
Solving for x, we get ...
x = 5/sin(30) = 5/0.5
x = 10
_____
It can be helpful to remember that the side ratios in a 30°-60°-90° triangle are ...
1 : √3 : 2
That is, the hypotenuse is 2 times the length of the side opposite the 30° angle. Here, that means x = 2×5 = 10, as we found above.
