The vertices of δabc are a(1,–2), b(1,1), and c(5,–2). which could be the side lengths of a triangle that is similar but not congruent to δabc? 3, 4, and 5 units 9, 12, and 15 units 6, 4, and 5 units 9, 12, and 5 units

Option B.

Step-by-step explanation:

The vertices of ΔABC are A(1,–2), B(1,1), and C(5,–2).  

Distance  formula:

Using distance formula we get

The length of sides are 3,4 and 5.

We need to find the side lengths of a triangle that is similar but not congruent to ΔABC.

It means the sides of new triangle are 3k, 4k and 5k, where k is a positive number and not equal to 1.

For k=3, the sides of new triangle are

The side lengths of a triangle that is similar but not congruent to ΔABC are 9, 12, and 15 units .

Therefore, the correct option is B.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
