<h3>
Answer: Choice A) 1/3</h3>
================================================
Work Shown:
x = preimage length = 12
y = image length = 4
z = scale factor
z = y/x
z = 4/12
z = (1*4)/(3*4)
z = 1/3
The scale factor is 1/3.
This means the image is 1/3 of the length of the preimage.
The correct answer would be B. 0.94.
In order to find this, divide the numbers in the top of the table by those in the bottom. below are some examples for you:
53.99/59.21 = 0.91
62.05/66.27 = 0.94
81.47/87.54 = 0.93
Taking these values, we will note that the answer that is closest to all of these is B. 0.94
Answer:
x = 14
Step-by-step explanation:
→ Set up an equation
4x + 15 + 39 = 110
→ Simplify
4x + 54 = 110
→ Minus 54 from both sides
4x = 56
→ Divide both sides by 3
x = 14
Answer:
In total there are 50 students.
Step-by-step explanation:
Since in a group of students 20 study account, 21 study mathematics, 18 study history, 7 study account only, 10 study mathematics only, 6 study account and mathematics only and 3 study mathematics and history only, to determine how many student are there altogether the following calculation must be performed:
7 + 10 + 6 + 3 = 26
Account = 20 - 7 - 6 = 7
Mathematics = 21 - 10 - 6 - 3 = 2
History = 18 - 3 = 15
26 + 7 + 2 + 15 = X
50 = X
Therefore, in total there are 50 students.
1/9 = 1.11
29/8 = 3.63
-------
3.73 = 269/72
or....
1/9 >>> 8/72 (72 is the common denominator) (Multiply the N and D by 8)
29/8 >>> 261/72 (72 is the common denominator) (Multiply the N and D by 9)
-------------
269/72
