To figure out long it took for Ingrid to walk her dog,multiply 3*1 and 1/2 or 3*1.5 to get 4.5 hours or 4 and 1/2 hours.
This is a right triangle (hence the 90° angle), so you'd find the legs (both are the same length of a right triangle) by using Pythagoras Theorem (a2 + b2 = c2) Since you have the hypotenuse (6"), just go backwards. 62 = 36 = a2 + b2. Like I said before the legs are the same length so you can rewrite it as 36 = 2x2, where x = either a or b. Then just solve for x.
The simplified form of the expression ( 6 1/5 - 3 3/4 ) as a mixed fraction .
<h3>What is the simplified form of the expression?</h3>
Given the data in the question;
6 1/5 - 3 3/4
First we convert the mixed fraction into an improper fraction.
6 1/5 = ( 6×5 + 1 )/5 = ( 30 + 1 )/5 = 31/5
3 3/4 = ( 3×4 + 3)/4 = ( 12 + 3 )/4 = 15/4
Hence;
31/5 - 15/4
We re-write both terms with common denominator.
( 31/5 × 4/4 ) - ( 15/4 × 5/5 )
124/20 - 75/20
Now, we can combine the denominators over common denominator.
( 124 - 75 )/20
( 124 - 75 )/20
49/20
Next we convert to a mixed fraction
We can get 20 from 49, 2 times with a remainder of 9
Hence
The simplified form of the expression ( 6 1/5 - 3 3/4 ) as a mixed fraction .

Answer:
1/3
Step-by-step explanation:
The scale factor is the ratio of image lengths to original lengths. For this pair of figures, the scale factor is ...
A'B'/AB = 2/6 = 1/3
The scale factor is 1/3.
