Answer:
94.2 ft of fencing
Step-by-step explanation:
To answer this, find the circumference, C, of the garden, using the circumference formula C = 2(pi)r.
Here, with r = 15 ft, we get C = 2(3.14)(15 ft) = 94.2 ft of fencing will enclose this garden.
Answer:
20 hours
Step-by-step explanation:
We can work easier if we think in terms of an hour
the first equation that we can write is
A + B = 1/4 (its meaning is that in an hour A and B fill 1/4 of the cistern)
the second equation we can write is
A + C = 1/5 (its meaning is that in an hour A and C fill 1/5 of the cistern)
the third equation that we can write is
B = 2C (its meaning is that in an hour B fill 2 times C the cistern)
now we can substitute the value of B in the first two equations
A + 2C = 1/4
A + C = 1/5
A = 1/5 - C
1/5 - C + 2C = 1/4
C = 1/4 -1/5
C = (5-4)/20
C = 1/20 (this means that in an hour C will fill 1/20 of the cistern, so it takes 20 hours to fill the entire cistern)
A = 1/5 - 1/20
A = (4-1)/20 = 3/20
B = 1/20 *2 = 1/10

Answer:
False
Step-by-step explanation:
According to the section, "When Good Bananas Go Bad", we are made to understand that one of the reasons why the TR4 fungus can spread easily through banana roots is because, there is only one variety, which is the Cavendish variety. Experts advise that people should develop interest in other varieties like the Manzano, which has the taste of Apple and Strawberry.
Another reason given for the spread of the disease is increased human transportation. Although growing one type of banana would be beneficial for companies, the fact that they have the same genetic material, aids the spread of the disease. So, diversification is advised.
