a. Select the system of equationslokat model the situation. Solve by using substitution.

Answers

Answer:

A.

Step-by-step explanation:

The entrance fee of an adult is equal to $37 and the entrance fee of a child is equal to $24.

What is a system of equations ?

A system of equations is a set or collection of equations that you deal with all together at once.

It is given that :

The total entrance fee for a group of 4 adults and 3 children = $220

and

The total entrance fee for a group of 2 adults and 1 child = $98

Let's assume that the entrance fee for an adult is x and entrance fee for a child is y.

So , the equations can be written as :

4x + 3y = $ 220  --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 1

2x + y = $ 98  --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 2

Now , multiply equation 2 by 2 :

4x + 2y = $ 196  --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 3

Subtracting equation 3 from equation 1 , we get :

(4x - 4x) + (3y - 2y) = $220 - $ 196

y = $24

or entrance fee of a child is $24.

Now , substituting the value of y in equation 1 , we get :

4x + 72 = $220

4x = 148

x = $37

or entrance fee of an adult is $37.

Therefore , the entrance fee of an adult is equal to $37 and the entrance fee of a child is equal to $24.

Mr. Flores opened an account with a deposit of $5,000.


• The account earned annual simple interest.

• He did not make any additional deposits or withdrawals.

• At the end of 4 years, the balance of the account was $6,500.


What is the annual interest rate on this account?

A. 5.8%

B. 7.5%

C. 3.3%

D. 1.9%

Answers

Answer:

B. 7.5%

Step-by-step explanation:

First, we need the Simple Interest (S.I)

Total = Principal + Simple Interest

T = P + S.I

6500 = 5000 + S.I

[make S.I the subject of the formula]

S.I = 6500 - 5000

S.I = 1500

Simple Interest = (Principal × Rate × Time) / 100

S.I = (P × R × T) / 100

1500 = (5000 × R × 4) / 100

1500 = 20000R / 100

1500 = 200R

[divide both sides of the equation by 200]

1500 / 200 = 200R / 200

R = 1500 / 200

R = 7.5

The annual interest rate is 7.5%

Axel and Carl both volunteer at a science museum. The manager needs one helper at a time for at most 18 hours this month. Axel wants to work at least 6 hours. The manager wants Carl to work no more than twice as many hours as Axel. Let a represent the number of hours that Axel works. Let c represent the number of hours Carl works. Which system of inequalities represents the constraints of this problem situation?

Answers

We want to find a system of inequalities that models the given situation.

We will find the system:

a + c ≤ 18

a ≥ 6

c ≤ 2*a

First we define the variables:

c = number of hours that Carl works.a = number of hours that Axel works

The given information is:

The manager needs one helper at a time for at most 18 hours.

From this we can write:

a + c ≤ 18

Axel wants to work at least 6 hours.

a ≥ 6

The manager wants carl to work no more than twice as many hours as Axel.

c ≤ 2*a

The system is then:

a + c ≤ 18

a ≥ 6

c ≤ 2*a

The Lucas numbers are defined by the recursive formula t1 = 2, t2 = 1, tn = tn - 1 + tn - 2, where n âN and n > 2. What are the first 9 Lucas numbers?

Answers

The first two are given to you, [tex]t_1=2[/tex] and [tex]t_2=1[/tex]. Use the recursive formula to get the 3rd term; then use the 2nd and 3rd terms to get the 4th; and so on.

Since the n-th Lucas number is the sum of the previous two Lucas numbers, you have

[tex]t_3 = t_2 + t_1 = 1 + 2 = 3[/tex]

[tex]t_4 = t_3 + t_2 = 1 + 3 = 4[/tex]

[tex]t_5 = t_4 + t_3 = 4 + 3 = 7[/tex]

[tex]t_6 = t_5 + t_4 = 7 + 4 = 11[/tex]

[tex]t_7 = t_6 + t_5 = 11 + 7 = 18[/tex]

The owner of an organic food store would like to analyze the sales data to determine if the business is growing, declining or remaining flat. The owner has the following data: Sales Revenue Last Year = $350,000 // Sales Revenue Current Year = $402,000. What is the sales growth? Question 3 options: 10% 17% 13% 15%

Answers

The percentage sales growth recorded by the food store is 15%

Given the Parameters :

Last year revenue = $350,000

Current year revenue = $402,000

The growth sales can be obtained using the relation :

Change in revenue / Last year revenue) × 100%

Change in revenue = Current year - Last year

Change in revenue = $402,200 - $350,000 = $52,200

Hence, percentage sales growth :

(52,200 / 350,000) × 100% = 14.914 %

Therefore, the percentage sales growth is 15%.

You may choose which civilization to research and highlight. Examples include:China, including the Tang, Song, Yuan, and Ming dynastiesThe Byzantine EmpireThe Mongol EmpireBackground InformationFollowing the death of Muhammad, early caliphs expanded Muslim empires throughout the Arabian Peninsula and into the Middle East. The Umayyad dynasty extended Muslim empires west to Spain and east into Persia. The Abbasid dynasty continued to rule much of this same territory for another five hundred years.After the fall of the Abbasid dynasty, the Ottoman Empire rose in Anatolia. As the Ottoman Empire expanded, two other Muslim empires were formed in Persia and India: the Safavid and Mughal Empires. These three empires existed in parallel for two hundred years, until the Safavid and Mughal Empires ended. During this same era in world history, several other civilizations continued to expand and develop. For example, several Chinese dynasties controlled territory in East Asia. The Byzantine Empire persisted in the eastern Mediterranean region from the 4th century CE until the 15th century CE. Also, in the 13th century CE, the Mongol Empire rapidly spread across Asia and influenced Europe and the Middle East.Historians use time lines to track the order of key events in different time periods. Time lines also create opportunities to compare and contrast events that took place in different regions. Focus your time lines on one topic, such as rulers or politics.
