Factors are the two numbers you multiple to get a certain number. What I use to find factors of a number is a factor tree. It is a fast and very simple way of helping find factors. For example, lets use the number 30. We have to find the numbers that can be multiplied to get 30.
Now find the biggest number that can go into 30. Which would be 15 times 2.
So it would look like this:
30
^
15 2
Answer:
14: B. 40 C. 40 D. 100
Step-by-step explanation:
a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100.
To double check just add 100+40+40=180
R is the origin (0,0). The point at the origin stays where it is assuming the center of dilation is the origin.
More technically we can multiply each coordinate of point R by the scale factor 0.5
x*k = 0*0.5 = 0
y*k = 0*0.5 = 0
Answer: Choice B. R' (0,0)
Answer:
- Both are terminating decimals
Step-by-step explanation:
<u>Answer to your questions:</u>
- First of all, both A and B are correct and both quotients are terminating decimals.
- To find out if the decimal is terminating or not, multiply the quotient by divisor. If you get exactly the same number as dividend, then it is terminating otherwise it is non-terminating.
- The fraction may have greater numerator than denominator, in this case the quotient will be greater than one.
- Now regarding simplification. You would be asked to give an answer rounded to some extend. One decimal place, two decimal places, 3 significant numbers etc. For the first operation you would get 34.8 (rounded to nearest tenth).
- Or you may be asked to have a best estimated result. In this case you would round the initial numbers and find results. 205/714 ≈ 0.29
(-4x + 9) - (2x - 1)
5 - (2x - 1)
5 - 2x + 1
-2x + (5 + 1)
-2x + 6
