The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 101010 denarius per day to support 333 legionaries and 333 archers. It only costs 333 denarius per day to support one legionary and one archer. Use a system of linear equations in two variables.

### Answers

Complete question :

The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legionaries and 3archers. It only costs 3 denarius per day to support one legionary and one archer. Use a system of linear equations in two variables. Can we solve for a unique cost for each soldier?

Answer:

No unique solution

Step-by-step explanation:

Given that:

Cost of supporting 3 legion aries and 3 archers = 10 denarius daily

Cost of supporting one legionary and one archer = 3 denarius

Let:

Legionaries = l ; archers = a

Equation for the first sentence :

3l + 3a = 10 - - - (1)

Second sentence :

l + a = 3 - - - - - (2)

From (2)

l = 3 - a

Substituting l = 3 - a into (1)

3(3 - a) + 3a = 10

9 - 3a + 3a = 10

9 - 0 = 10

The variable cancels out, Hence, ( there is no unique solution to find the cost of each soldier)

**Answer:**

No; the system has no solution.

**Step-by-step explanation:**

We'll use *L* to represent the cost per day of a legionary, and we'll use *A* to represent the cost per day of an archer. So we have the following system of equations:

3L+3A=10

L+A=3

If we multiply both sides of the second equation by 3, we get the equation 3L+3A=9

But this indicates that the cost to support 3 legionaries and 3 archers is 9 denarius. The first equation indicates that it costs 10 denarius to support 3 legionaries and 3 archers.

The cost cannot be 9 denarius and 10 denarius at the same time.

Henceforth the answer is:

**No; the system has no solution.**

John's phone company offers 2 cell phone plans, A and B. Both plans offer 450 free minutes per month, but plan A charges $40 per month and $0.35 for each additional minute, while plan B charges $45 per month and $0.30 for each additional minute. Which inequality shows the number of minutes, x, that John may use in a month in order to make plan B the better plan for that month?

A.

40 + 0.35(x − 450) 45 + 0.30(x − 450)

D.

40 + 0.35x > 45 + 0.30x

### Answers

**Answer: ** 45 + 0.30(x-450) > 40 + 0.35(x-450)

**Step-by-step explanation:**

Given: Free minutes = 450

**For plan A,**

Fix charge = $40

Charge per minute after free minutes = $0.35

**For plan B,**

Fix charge = $45

Charge per minute after free minutes = $0.30

Let x be the additional minutes.

**Charges according to plan A** = 40 + 0.35(x-450)

**Charges according to plan B** = 45 + 0.30(x-450)

If plan B is better than plan A.

45 + 0.30(x-450) > 40 + 0.35(x-450)

**Required inequality : ** 45 + 0.30(x-450) > 40 + 0.35(x-450)

The bill at a restaurant came to $136.40.The customer decided to leave a 15% tip.What was the total bill including tip.

### Answers

**Answer:**

$156.86

**Step-by-step explanation:**

To calculate tip, you need to multiply the total bill by the percent tip you are going to leave. In this case the bill is $136.40, and the customer is going to leave a 15% tip. So, you would want to move the decimal place over to the left by 1, which you should get 13.64 as your number. Then divide it in half, which should give you 6.82. Now add 13.64 and 6.82 with the original bill price. If you don't add the 13.64 you would've forgotten the 10% part of the tip. At the end you should get $156.86 as your final bill.

Kimberly tracked the cartoons shown on the channel her kids watch for a week. The probability that the show had animals in it was 0.7 . The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times?

### Answers

Answer:

p(A or more than 10) = 0.7 + 0.4 - 0.2 = 0.9

Step-by-step explanation:

Given the following probabilifu distribution :

Probability that show had animals in it :p(A) = 0.7

Probability that show aired more than 10 times : p(more than 10) = 0.4

Probability that show had animals and aired more than 10 times: p(A n more than 10) = 0.2

Recall:

P(A or B) = p(A) + p(B) - p(A n B)

Hence,

p(A or more than 10) = p(A) + p(more than 10) - p(A n more than 10)

p(A or more than 10) = 0.7 + 0.4 - 0.2 = 0.9
