10. Ken has 22 coins, some of which are dimes and the rest are quarters. Alto-
gether, the coins are worth more than $3. 40. At least how many of the
coins are quarters? At most how many are dimes?
Answer: Ken has 22 coins, some of which are dimes and the rest are quarters
Step-by-step explanation:Step 1. Let x be the number of dimes and let 25-x be the number of quarters.
Step 2. Let 0.10x be the total cost for x number of dimes
Step 3. Let 0.25(25-x) be the total cost for 25-x number of quarters.
Step 4. Since the man has $4.60, then 4.60=0.10x+0.25(25-x). Solving for x yields the following steps

Using an absolute-value inequality, describe the set of numbers whose distance from 4 is greater than 5 units. Draw a graph of this set on a number line. Finally, describe this set of numbers using inequalities without absolute value signs.
The solution to the absolute-value inequality is x > 9; and x < -1
What is an inequality?An inequality is an expression that shows the nonequal comparison of two or more numbers and variables.
Let x represent the unknown number, hence:
|x - 4| > 5
(x - 4) > 5; and -(x - 4) > 5
x > 9; and x < -1
The solution to the absolute-value inequality is x > 9; and x < -1

35%of?=242
options are:
a)729
b) 652
c) 693
d) 759
e) none of these
with explaination
Answer:
e) none of these
Step-by-step explanation:
35% of 242 would be 84.7%
We know this because we simply have to solve it!
We solve it by doing:
(35/100)*242
(35*242)/100
= 8470/100 = 84.7
We need to determine 35% of 242 now and the procedure explaining it as such
Step 1: In the given case Output Value is 242.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 242 = 100%.
Step 4: In the Same way, x = 35%.
Step 5: On dividing the pair of simple equations we got the equation as under
242 = 100% (1).
x = 35% (2).
(242%)/(x%) = 100/35
Step 6: Reciprocal of both the sides results in the following equation
x%/242% = 35/100
Step 7: Simplifying the above obtained equation further will tell what is 35% of 242
x = 84.7%
Therefore, 35% of 242 is 84.77
Compare the difference between an independent event and a dependent event.
Dependent event is when two events are dependent events, one event influences the probability of another event whereas independent event has no effect on the probability of another event occurring.
↪DEPENDENT EVENT
When two events are dependent events, one event influences the probability of another event. A dependent event is an event that relies on another event to happen first. Dependent events in probability are no different from dependent events in real life. If you want to attend a concert, it might depend on whether you get overtime at work. if you want to visit family out of the country next month, it depends on whether or not you can get a passport in time. More formally, we say that when two events are dependent, the occurrence of one event influences the probability of another event.
Simple examples of dependent events
Robbing a bank and going to jail.Not paying your power bill on time and having your power cut off.Boarding a plane first and finding a good seat.Parking illegally and getting a parking ticket.↪INDEPENDENT EVENT
An independent event is an event that has no connection to another event’s chances of happening (or not happening). In other words, the event has no effect on the probability of another event occurring. Independent events in probability are no different from independent events in real life. Where you work has no effect on what color car you drive. Buying a lottery ticket has no effect on having a child with blue eyes.
When two events are independent, one event does not influence the probability of another event.

Tamora just made the last of her monthly payments on her loan. she had been making these payments for the past nine years. the loan had a principal of $10,675 and an interest rate of 4.75%, compounded monthly. in addition, tamora paid $939.25 in service charges. what was tamora’s total finance charge? round all dollar values to the nearest cent. a. $939.25 b. $11,614.25 c. $3,403.53 d. $2,464.28 please select the best answer from the choices provided a b c d
Tamora’s total finance charge was $3,403.53 if Tamora paid in addition of $939.25 in service charges option (c) is correct.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We have:
Principal amount(Loan principal) = $10,675
Interest rate = 4.75 %
Monthly rate = 4.75/12% ⇒0.39583% ⇒ 0.00395
Additional amount she paid in service charge = $939.25
Number of months = 9×12 = 108 months
We can find the total finance charge as follows:
Finance charge = Total amount repaid +service charge - Loan principal
The formula for the monthly payment of the loan is given by:
[tex]\rm Monthly \ payment = \frac{Loan \ principal }{\frac{(1-(1+r)^-^n)}{r} }[/tex]
[tex]\rm Monthly \ payment = \frac{10675}{\frac{(1-(1+0.00395)^-^{108})}{0.00395} }[/tex]
After calculating, we get:
Monthly payment = $121.66
For 108 months, Tamora paid:
= 121.66×108
= $13,139.23
The finance charge will be:
= $13,139.23+$939.25-$10,675
= $3,403.53
Thus, Tamora’s total finance charge was $3,403.53 if Tamora paid in addition of $939.25 in service charges option (c) is correct.

Rewrite −2sin(x)+4cos(x) as A sin(x+ϕ). What is the value of A and ϕ?
Expand the target expression:
A sin(x + ϕ) = A (sin(x) cos(ϕ) + cos(x) sin(ϕ)) = -2 sin(x) + 4 cos(x)
Then we have
A cos(ϕ) = -2
A sin(ϕ) = 4
Recall that sin²(x) + cos²(x) = 1 for all x. Then
(A cos(ϕ))² + (A sin(ϕ))² = (-2)² + 4²
A² (cos²(ϕ) + sin²(ϕ)) = 4 + 16
A² = 20
A = √20 = 2√5
Also recall that tan(x) = sin(x)/cos(x) by definition. Then
(A sin(ϕ)) / (A cos(ϕ)) = 4 / (-2)
tan(ϕ) = -2
ϕ = arctan(-2) = -arctan(2)
