How Does 2 / 0.1 become 20?​

Answers

Answer 1

The decimal value 0.1 converts to the fraction 1/10

This is because the 1 in 0.1 represents "one tenth", as its in the tenths place.

So this means 2/0.1 is the same as 2/(1/10) or [tex]2 \div \frac{1}{10}[/tex]

Then we can follow these steps:

[tex]2 \div \frac{1}{10} = \frac{2}{1} \div \frac{1}{10}\\\\\\2 \div \frac{1}{10} = \frac{2}{1} \times \frac{10}{1}\\\\\\2 \div \frac{1}{10} = \frac{2*10}{1*1}\\\\\\2 \div \frac{1}{10} = \frac{20}{1}\\\\\\2 \div \frac{1}{10} = 20\\\\\\[/tex]

Note in the second step, we flip the second fraction to go from a division problem to a multiplication problem. The general rule is [tex]\frac{A}{B} \div \frac{C}{D} = \frac{A}{B} \times \frac{D}{C}[/tex]. The first fraction does not flip.

Calculate the cost for the fuel needed for Sam to drive to Nanaimo to tofino

(15 points)

Answers

Answer:

cost of Sam of fuel from Nanaimo to Tofino(207km) is $34.78

Step-by-step explanation:

Diatance from Nanaimo to Tofino is 207km.

Now:

fuel consume in 100km= 12L

fuel consume in 1km=12/100L

We have to find consumption of fuel in 207km.

fuel consume in 207km=12/100 × 207km

= 24.84L

Price of 1 liter= $1.40

Price of 24.84 liters=$1.40 × 24.84

=$34.78

<2=(10y+20)
<3 =100 ​

Answers

Answer:

1008010080

x = 10

y = 6

Step-by-step explanation:

We can use the vertical angle theorem to solve for most of this problem. We know that 1/3 will have the same measure and so will 4/2. We can create an equation to solve for 1 and 3.

10x = 100

x = 10

We aren't given angle 4 so we are going to have to solve that ourselves. We can create an equation knowing that 4 and 3 will create a supplementary angle.

100 + z = 180

z = 80

Now, that we have angle 4, we know that angle 2 will have the same measure because they are vertical angles. Now to find the value of y, we can take the angle measure and solve for it.

10y + 20 = 80

10y = 60

y = 6

Step-by-step explanation:

So Maria's team skipped 8 turns, losing 8 points, putting them at -8 points. But, Maria's team also guessed correctly 6 times, putting them at -8 + 6 points.

So now we can subtract 8 from 6, or you could subtract 6 from 8(If you do the latter, make sure the answer is negative.):

-8 + 6 = -2

or

6 - 8 = -2

or

8 - 6 = 2 Then make it negative: -2

Name 4 collinear points

Answers

Answer:

B) H, N, K, I

Step-by-step explanation:

Collinear points are points that are on the same line. Therefore, the answer is B.

The points H, N, K, and I are collinear which is the correct answer that would be an option (B).  

What are the collinear points and the coplanar?

Collinear points are defined as points that are along a straight line represented by a collinear. Because a straight line may be drawn continuously between any two points, they are always collinear. There can be a collinear relationship from three or more points, although it is not necessary.

A group of points that are coplanar, or a planar surface that extends endlessly in all directions, are all located on the same plane. Four or more points may or may not be coplanar, however, any two or three points are always coplanar.

We have given a line and a planar surface with points H, N, K, I, M, N, O, J, K, and L.

At the line, points H, N, K, and I are collinear.  

Hence, the points H, N, K, and I are collinear which is the correct answer that would be an option (B).

Answers

Answer:

5x+9 =  109

3x+11 =71

Step-by-step explanation:

A linear pair adds to 180

5x+9  + 3x+11 =180

Combine like terms

8x + 20 =180

Subtract 20 from each side

8x +20-20 = 180-20

8x = 160

Divide each side by 8

8x/8 = 160/8

x=20

5x+9 = 5*20+9 = 100+9 = 109

3x+11 = 3*20+11 = 60+11=71
