5. Using the equation y=2x+5, construct a table and graph the line

Answers

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)

Answer: See the graph below.

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger​ block?

Answers

Answer:

I think the larger block has a scale 25 times bigger than the smaller block since 100 divided by 4 equals 25

Please tell me if I'm wrong

I hope this helps

:D

Answer:

The Scale factor is 5.  

Step-by-step explanation:  

Because the area has cm^2  to find the scale factor you find the number it takes to get from one area to the next and take the square root.

4X = 100

X = 100/4

X = 25 (Take the sqrt because of area)

X = sqrt(25)

X = 5

The Scale factor is 5.

The gasoline consumption of a bus is 30l/100km and of a car is 9l/100km. To go on a 250 km trip, 30 people can either go by car with 5 people in each car or take one bus for all 30 people. Which method of transportation uses less gasoline, and how much less?

Answers

Answer:

The bus will take less consumption and by 60 litre

Bus uses less gasoline by 601.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Case 1: Bus

Consumption/ 100Km= 301

and, for 250 Km= 301 /100 x 250

                          = 751

Case 2: Car

Total = 80 people

Total cars= 30/5 = 6

Consumption/ 100Km= 91

and, for 250 Km= 91 /100 x 250

                          = 22.51

Consumption by 6 cars = 6 x 22.51 = 1351

Difference between Gasoline Consumption = 1351-751 = 601
