224
Duque de Caxias
242
Rio de Janeiro
193
Campinas
185

Guarulhos
120
Fortaleza
201

Henry’s original plan was to visit Duque de Caxias, Campinas, Rio de Janeiro, and Guarulhos. However, he only has R$699 to spend, so he cannot afford to use his original itinerary. Which of the following changes will be the cheapest swap Henry can make and still come in under budget?
a.
Replace Duque de Caxias with Salvador.
b.
Replace Duque de Caxias with Fortaleza.

First, sum up the total expenses for the original plan

Duque de Caxias + Campinas + Rio de Janeiro + Guarulhos = 242+185+193+120 = R$740

It is clearly over the intended budget. The average cost per itinerary is around R$200 so we will consider making a swap on either Duque de Caxias and Rio de Janeiro.  Possible answers are (b) or (c)

for (b) Replace Duque de Caxias with Fortaleza, we will have

Fortaleza + Campinas + Rio de Janeiro + Guarulhos =
⇒ 201+185+193+120 = R$699  ⇒ This is exactly the budget intended for the trip

for (C) Replace Rio de Janeiro with Porto Alegre
Duque de Caxias + Campinas + Porto Alegre  + Guarulhos =
⇒ 242 + 185 + 153 +120 = R$ 700 ⇒ This is over R$1

The answer is (b)

Last week, Robert’s family discussed insurance. He learned about some of the factors that may or may not affect each family memb
ale4655 [162]

Answer:

The classification are as follows;

1) Robert's older brother Howard has been working as an electrician for the last year

  • Increases insurance need

2) Robert's younger sister Amelia recently obtained her driver's licence and has already been at fault for a car accident

  • Increases insurance need

3) Robert exercises regularly makes good grades in school, and eats healthy food

  • Does not affect insurance needs

4) Robert's uncle goes scuba diving each summer and enjoys snowboarding in the winter

  • Increases insurance need

5) Robert's mother enjoys scrap-booking and making quilts in her spare time

  • Does not affect insurance needs

6) Robert's grandfather, Eugene, recently celebrated his 82nd birthday

  • Increases insurance need

Step-by-step explanation:

1) The statements are analyzed as follows;

Robert's older brother Howard has been working as an electrician for the last year

One of the four types of insurance cover that everyone needs is the long-term disability coverage, more so for Howard who is working as an electrician as 30% of new entrants into the workforce will become disabled

2) Robert's younger sister Amelia recently obtained her driver's licence and has already been at fault for a car accident

Given the likelihood of an accident occurring and the (unexpected) cost of being involved in an accident having an auto insurance will help with the expenses and protect the insurance holder against the possible litigation that results from being involved in the accident

3) Robert exercises regularly makes good grades in school, and eats healthy food

Given that Robert is a physically fit good student that eats a healthy diet, there are few potential for losses due to Robert's current status or activities, therefore, his activities does not affect insurance needs

4) Robert's uncle goes scuba diving each summer and enjoys snowboarding in the winter

Given the physical nature of Robert's uncle's activity, an accident insurance is needed which in the event of an injury, will help in taking care of the expenses so as to increase the insurance holder's peace of mind

5) Robert's mother enjoys scrap-booking and making quilts in her spare time

The activities of Robert's mother are less injury prone such that they do not affect her insurance needs

6) Robert's grandfather, Eugene, recently celebrated his 82nd birthday

Due to the age status of Robert's grandfather, it will be prudent for there to be consideration for the provision for the people that Robert's grandfather will leave behind such as mortgage payments, loans that are outstanding and possible university tuition costs that may come up in the future as well as funeral costs and daily living expenses of loved ones left behind

Therefore, there is an increased insurance need due to age status

the vertex of this parabola is at (3,-2). When the x-vaue is 4, the y-value is 3. What is the coefficient of the squared express
bixtya [17]
<h3>Answer:   5</h3>

=========================================================

Explanation:

Vertex form is

y = a(x-h)^2 + k

We are told the vertex is (3,-2), so we know (h,k) = (3,-2)

y = a(x-h)^2 + k will update to y = a(x-3)^2 - 2

--------

Then we also know that (x,y) = (4,3) is a point on the parabola. Plug those x and y values into the equation and solve for 'a'

y = a(x-3)^2 - 2

3 = a(4-3)^2 - 2

3 = a(1)^2 - 2

3 = a - 2

3+2 = a

5 = a

a = 5

This is the coefficient of the x^2 term since the standard form is y = ax^2+bx+c.

Find the slope of 10y = 7x + 5.<br> Round to the third.
hram777 [196]

Answer:

0.7

Step-by-step explanation:

10y = 7x + 5

Divide both sides by 10.

y = 7x/10 + 5/10

y = 0.7x + 0.5

On a straight line of the form y = kx + m, k is the slope of the line.

In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

Answer: 0.7
