Answer:
216 cm³
Step-by-step explanation:
1/3x + 63 = 5/8x
subtract 1/3x from each side; (1/3x = 8/24x and 5/8x = 15/24x)
63 = 7/24x
7x = 63(24)
7x = 1512
x = 216
The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour

Answer:

Step-by-step explanation:
A geometric mean is just
, where n is the number of terms.
i.e. Geometric mean of 5, 6, 7: there are three values, so the mean is ![\sqrt[3]{5*6*7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%2A6%2A7%7D)
