Estimation is a process by which we do not exactly do the operation but predicts through pre-known facts and methods in order to determine the required. In this item, we are to predict or estimate the place of the decimal point to the answer when we divide the 42.56, dividend, and 22, our divisor.
We can say that 42 can be divided by 22 only once because twice of 22 is already 44. By this we can say that the decimal place will be after 1. There would only be one digit to the left side of the decimal point.
If we are going to answer the division problem, we get an answer of 1.934545..
Answer:
1/30 in fraction form.
0.033333333....
Step-by-step explanation:
The bottom answer is correct. I had some trouble with this so I had to find x and y in separate parts.
TO FIND X
notice that the top triangle and bottom triangles are similar, meaning if you multiple all three sides of one by a specific number, it becomes the same size as the bottom triangle.
17 x n = 8, therefore n=8/17
8 x n = X, therefore X=64/17
For some reason, this does not give a correct value for Y, so I had to use trig
TO FIND Y
Notice that the angle DAB is the same as DBC (lets call this angle Ø)
Using trig rule, we know that the cos of an angle is equal to the adjacent side divided by the hypotenuses.
We can now form some equations:
cosØ = 15/17 (from the top triangle)
cosØ = 8/Y (from bottom triangle)
Now we know that Y=(8x17)/15 = 136/15
X=64/15 Y=136/15
Distribute 4 to both 1 and 8x
4(8x) = 32x
4(1) = 4
32x + 4 is your answer
A) is your answer
hope this helps
The answer for this question is letter D.
This is because correlation coefficient focuses on the linear relationship between two variables. The numbers between -1 and 1 should be one of the value related to the bill. As you can that letter D is the most closest and realistic answer.
