The solution of your problem is shown on the picture below.
Answer:
-6
Step-by-step explanation:
Estimate :
7 1/8 rounds to 7
6 * 7 = 42.....about 42 yds
Step-by-step explanation:
what is THE partial product ? there is a mistake in your problem description.
it must read "what are valid partial products".
1262×3 has the following partial products :
1000×3 = 3000
200×3 = 600
60 × 3 = 180
2×3 = 6
-----------
3786
so, D seems to be the best answer, because both numbers are partial products here.
A, B and C have each only one correct.
Answer - Perpendicular
First, find the slope of each line by using the point slope formula [(y2-y1)/(x2-x1)]. You should get that the slope line 1 is -2/3 and the slope of line 2 is 3/2. Using this, we can conclude that both the lines are perpendicular because their slopes are opposite reciprocals (meaning you flip one fraction and change its sign to get the other fraction).
