Answer:

2 hours

Step-by-step explanation:

Using the work word problems, 1/3 + 1/6 = 2/6 + 1/6

3/6 = 2

setting 1/x, where 1 is a completed job, then x/1 = 2/1, therefore, the combined effort finishes the job in 2 hours. This is from the best of my knowledge. Purple Math is a great resource if extra help is needed.

Find the scale factor of the dilation. Then tell whether it is enlargement or reduction.​
mariarad [96]

Answer:

  a) 1/2; reduction

  b) 5/4; enlargement

Step-by-step explanation:

In each case, the scale factor is CP'/CP. When it is more than 1, the dilation is an enlargement.

Even before you run the numbers, you can tell if it is an enlargement or not. If the dilated figure is larger, P is closer to C than is P'. If P' is closer to C, then it is a reduction.

a) CP'/CP = (4-2)/4 = 2/4 = 1/2 . . . . a reduction

__

b) CP'/CP = 25/20 = 5/4 . . . . an enlargement
