A rocket ship is travelling at an average speed of 1.75 × 104 miles per hour. How many miles will the rocket ship travel in 1.2 × 102 hours? 1. Write the expression: (1.75 × 104)(1.2 × 102)

2. Rearrange the expression: (1.75 × 1.2)(104 × 102)

3. Multiply the coefficients: (2.1)(104 × 102)

4. Apply the product of powers: 2.1 × 10y

The rocket ship will travel 2.1 × 10y miles. What is the value of y in the solution?

y =

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

answer: it is d

step-by-step explanation:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
