Answer:
2 9/10 miles
Step-by-step explanation:
Ellis rides 29/5 miles a day, today she rode half of it, that is 29/10 miles which is equivalent to 2 9/10.
Answer:
D) t=4d+5
Step-by-step explanation:
If d=1,
![t=4\times 1+5\\t=9](https://tex.z-dn.net/?f=t%3D4%5Ctimes%201%2B5%5C%5Ct%3D9)
If d=2,
![t=4\times2+5\\=8+5\\=13](https://tex.z-dn.net/?f=t%3D4%5Ctimes2%2B5%5C%5C%3D8%2B5%5C%5C%3D13)
If d=4,
![t=4\times4+5\\=16+5\\=21](https://tex.z-dn.net/?f=t%3D4%5Ctimes4%2B5%5C%5C%3D16%2B5%5C%5C%3D21)
Therefore,
![t=4d+5](https://tex.z-dn.net/?f=t%3D4d%2B5)
Answer:
(sqrt(7))/3 or decimal 0.8819171036881968635005385845464201419034197276941500601227781530...
Step-by-step explanation:
Simplify the following:
(sqrt(14))/(sqrt(18))
Hint: | Simplify radicals.
sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):
(sqrt(14))/(3 sqrt(2))
Hint: | Multiply numerator and denominator of (sqrt(14))/(3 sqrt(2)) by sqrt(2).
Rationalize the denominator. (sqrt(14))/(3 sqrt(2)) = (sqrt(14))/(3 sqrt(2))×(sqrt(2))/(sqrt(2)) = (sqrt(14) sqrt(2))/(3×2):
(sqrt(14) sqrt(2))/(3×2)
Hint: | Multiply 3 and 2 together.
3×2 = 6:
(sqrt(14) sqrt(2))/6
Hint: | For a>=0, sqrt(a) sqrt(b) = sqrt(a b). Apply this to sqrt(14) sqrt(2).
sqrt(14) sqrt(2) = sqrt(14×2):
(sqrt(14×2))/6
Hint: | Multiply 14 and 2 together.
14×2 = 28:
(sqrt(28))/6
Hint: | Simplify radicals.
sqrt(28) = sqrt(2^2×7) = 2 sqrt(7):
(2 sqrt(7))/6
Hint: | In (2 sqrt(7))/6, divide 6 in the denominator by 2 in the numerator.
2/6 = 2/(2×3) = 1/3:
Answer: (sqrt(7))/3
Answer:
True
Step-by-step explanation:
The real answer is either A. Or from what I've been taught, Columbus thought that he could sail around the world to reach to India and did NOT know there were other lands. And he landed in America and he thought it was India.
