Answer:
BF = 30
Step-by-step explanation:
Each midsegment is half the length of the parallel side of the triangle. CE is 60 and is parallel to BF, so BF = 60/2 = 30.
Answer:
Step-by-step explanation:
vector u=<(11-(-7),(-5-2)>=<18,-7>
as direction is opposite to u
so vector v=-3(18,-7)=(-54,21)
Start out with 24 and then move onto dividing 24 by 3/4 your answer should be 32
The beetle ate everything except the front cover of volume one and the back cover of volume four.
The thickness of the front cover of volume one and the back cover of volume four = 0.5 cm + 0.5 cm = 1 cm.
Total distance covered by the books = 4 x 8cm = 32 cm.
Therefore, total distance travelled by the beetle is 32 - 1 = 31 cm.
Answer:
95% chance
Step-by-step explanation:
10+6+3+1=20
1/20=0.05 or 5%
5% chance of the marble being green
100%-5%=95%
