Answer:
9.899495
Step-by-step explanation:
=(0−(−7))2+(−6−1)2−−−−−−−−−−−−−−−−−−−√
d=(7)2+(−7)2−−−−−−−−−−√
d=49+49−−−−−−√
d=9–√8
d=9.899495
6 sets of birds were in a brown crate and 2 sets of birds were in a green crate? How many birds altogether were in those crates.
Answer:
7) a = 60; b = 100
8) c = 20
9) d = 45
Step-by-step explanation:
7)
a + 120 = 180
a = 60
b + 80 = 180
b = 100
8)
5c + 4c = 180
9c = 180
c = 20
9)
3d + d = 180
4d = 180
d = 45
Answer:
D
Step-by-step explanation:
There are 50 clips and 14 of them are purple.
Probability of picking purple is 14/50 or 7/25. Probability of picking non purple is 1 - 7/25 = 18/25
Answer: 54.4 mph
Step-by-step explanation:
First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:
= Speed * time
= 68 * 4
= 272 miles
This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:
= Distance / time
= 272/5
= 54.4 mph
