Mathematics
1 answer:
Elza [17]3 years ago
4 0

Answer:

y=-1/3x-1

Step-by-step explanation:

1. Find the slope.

Start from the point on the y-axis and count down and over until you get to the other point marked on the graph. This gets you -1/3

Slope is -1/3

2. Find where the line crosses the y-axis. This is the y-intercept. On this graph, the line crosses the y-axis at (0,-1). The y-value is the intercept.

3. Put the equation in slope-intercept form. Slope intercept form is y=mx+b with mx being the slope and b being the y-intercept.

y=-1/3x-1

On a given day, 36 of the 445 students in a school were absent. What was the appproximate absentee rate that day?
Nata [24]

Answer: The approximate absentee rate that day would be 8.09%.

Step-by-step explanation:

Since we have given that

Number of students who were absent = 36

Total number of  students = 445

We need to find the approximate absentee rate that day :

Rate of absentee of that day would be

\dfrac{\text{Number of absentee}}{\text{Total number of students}}\times 100\\\\=\dfrac{36}{445}\times 100\\\\=8.09\%

Hence, the approximate absentee rate that day would be 8.09%.

HHenry is going on a trip to Brazil. He is currently deciding which cities he will visit during his stay. The table below shows
Karo-lina-s [1.5K]
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)

I would like to purchase 20 products at a cost of $65 per product. What would be my total with 3.5 sales tax
alexandr402 [8]

Answer:

Answer:

The total is: $ 1345.5

Step-by-step explanation:

It is given that:

I would like to purchase 20 products at a cost 65.00 per product.

This means that the cost of 20 products will be:

Also, there is a sales tax of 3.5%

This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.

i.e. he need to pay 3/5% on $ 1300

This means that the amount of tax he need to pay is: 3.5% of 1300

                                                                             =  3.5%×1300

                                                                            = 0.035×1300

                                                                           = $ 45.5.

Hence, the total cost is: $ 1300+$ 45.5

This means that the total cost is: $ 134.5
