Answer:
choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec
Step-by-step explanation:
To find average speed between 3 and 8 seconds, find the total distance traveled during that time.
650 meters at 3 seconds
to 375 meters at 8 seconds
then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec
Answer:
There are three main types of congruence transformations: reflections (flips), rotations (turns), and translations (slides). These congruence transformations can be used to obtain congruent shapes or to verify that two shapes are congruent
You take 4/15 and make the denominator 315
4/15 = ?/315
15 x 21 = 315
4 x 21 = 84
4/15 = 84/315
so 84 of 315 members are male
315 - 84
= 231
231 are female
