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.

What was Maria’s team score
Answer:
-2
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

g(x) = –2x – 9 What is g(–7)? A. 5 B. –1 C. –5 D. –23
Answer:
D. -23
Step-by-step explanation:
The question wants you to plug in the -7 into the equation. So in this case it wants you to plug the -7 in so it looks like this:
-2(-7)-9
Now it's just simplify which would be easy. Follow PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction). Do the multiplication first so you get -14-9 and then you'll get -23.

Can somebody help me solve this? Don’t just give me the answer, tell me how to get the answer to problems like these. I forgot what to do on these
Answer:
it would be 8^12
Step-by-step explanation:
when exponents are dividing eachother and the bases are the same it would be like
[tex] \frac{ {x}^{3} }{x} [/tex]
so it would turn into x^3-1 then the answer would be x^2

Name 4 collinear points
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).

Which of the following describes a correct process for solving the equation 3(x + 6) = 21 and arrives at the correct solution?
A. Divide both sides of the equation by 3, and then subtract 6 from both sides of the equation. The solution is x = 1.
B. Subtract 6 from both sides of the equation, and then divide both sides of the equation by 3. The solution is x = 5.
C. Distribute the 3, subtract 6 from both sides of the equation, and then divide both sides of the equation by 3. The solution is x = 5.
D. Add 6 to both sides of the equation, and then divide both sides of the equation by 3. The solution is x = 9.

The one and THE only common factor is 7, which is going to be the GCF
find the value of x and y
<1=(10x)
<2=(10y+20)
<3 =100
Answer:
1008010080x = 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

if angle 1 and angle 2 form a linear pair. if m angle 1=(5x+9) and m angle 2= (3x+11), find the measure of each angle
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

Calculate the cost for the fuel needed for Sam to drive to Nanaimo to tofino
(15 points)
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
Note:If you have question about it you can ask.Thanks
