Maria studied the traffic trends in India. She found that the number of cars on the roads increases by 10% each year. If there were 80 million cars in year 1 of her study, how many more cars were on the road in year 3 compared to year 2?

Answers

Answer 1

Answer:

Answer: 8.8 million

Step-by-step explanation:

Given: The number of cars in year 1= 80 million

As she found that the number of cars on the roads increases by 10% each year.

Now, 10% of 80 million= $0.10*80\ million=8\ million$

Thus, the number of cars in year 2= 80 million+8 million=88 million

Now, 10% of 88 million= $0.10*88\ million=8.8\ million$

Thus, the number of cars in year 3= 88 million+8.8 million=96.8 million

Now, the difference in the cars in year 3 compared to year 2=96.8 million-88 million

Thus, the difference in the cars in year 3 compared to year 2=8.8 million

Answer 2

Answer: Year 2 is 88 million and in year 3 it is 96.8 million. 96.8 million-88 million it makes 8.8 million. So the answer is 8.8 million people.

using a picture picture show how six people could share four sandwiches. then write an equation and solve. please explain

Answers

An equation $(total of part get by each people)/(number of parts in each sandwich)$ and the result is $(2)/(3)$

Further explanation

A sandwich is a food that consist of vegetables, sliced cheese or meat, placed on or between slices of bread, or any dish wherein two or more pieces of bread serve as a container or wrapper for another food type. Some people think that a sandwich on square bread should be cut diagonally, so the sandwich halves are two triangles. Other people prefer to cut the sandwich straight down the middle to make two rectangles

By using a picture picture show how six people could share four sandwiches. then write an equation and solve.

We can draw the sandwiches showed in the shape of square, and then make 6 divides to each sandwich so we can share it to six people precisely.

According to the picture, each people get one part of every sandwich, then there are 4 whole sandwiches where each sandwiche have 6 parts. So,

$(total of part get by each people)/(number of parts in each sandwich)$

$= (4)/(6) = (2)/(3)$

Answer details

Grade: 5

Subject: math

Chapter: sandwiches

Keywords: sandwiches, equation, picture, equation, people

Ok so split each of the 4 sandwiches into 3 parts. That means 4*3 because each sandwich is now made up of three pieces.

So that means there are 12 pieces in total.

Then you can give each person 2 pieces. So everyone is happy cause everyone gets 2 pieces of sandwich. Because there are 6 people.

Now um pictures... right.

Y=2x-20
y=-x+34 it is a substitution method

Answers

I will help you do it the correct way.

To solve by substitution, you must cancel out either x or y.
We will choose x, as -x and 2x are easier to change and cancel.
We multiply the second equation by 2 to make -x -2x, the opposite of 2x in the first equation.

y=-x+34
2(y = -x + 34)
2y = -2x + 78

We add the equations together.

y = = 2x - 20
2y = -2x + 68

y + 2y = 2x - 2x + 68 - 20
Combine like terms
3y = 48

isolate y

3y = 48
/3 /3
y = 16

Now we substitute 16 in for y in an original equation.
Let's choose the first equation.

Y=2x-20
16 = 2x - 20
Isolate x

16 = 2x - 20
+20 +20

36 = 2x
/2 /2
18 = x

x = 18
y = 16

The solution is (18, 16)

To check, substitute both into both equations and see whether or not the equation is true. (you can surely do this on your own)

What is the formula for a parallelogram

Answers

The formula is base*height.
This is because in a parallelogram (a slanted one), you can multiply base*height and the triangle from the other side can be moved.
Which is why it's also the formula for rectangle and squares since they are also parallelograms

It is Base times Height

Which is greater 2/5 or 2/6
