Answer:
shorter piece = 6. longer piece = 12
Step-by-step explanation:
short piece = s
long piece = l
l+s= 18
l= 6+s , substitute
6+s+s = 18
6+2s= 18
2s= 18-6
2s= 12
s=12/2
s= 6= shorter piece
l= 6+s
l= 6+6= 12 = longer piece
<h2>
6.7 hectometers is equal to "670 meters".</h2>
Step-by-step explanation:
We have,
6.7 hectometers
To convert 6.7 hectometers to meters.
We know that,
1 hectometer = 100 meters
⇒ 1 hm = 100 m
∴ 6.7 hectometers
= 6.7 × 100 meters
= 670 meters
∴ 6.7 hectometers (hm) = 670 meters (m)
Thus, 6.7 hectometers is equal to "670 meters".

Step-by-step explanation:
Answer:
The period of Y increases by a factor of 
with respect to the period of X
Step-by-step explanation:
The equation 
shows the relationship between the orbital period of a planet, T, and the average distance from the planet to the sun, A, in astronomical units, AU. If planet Y is k times the average distance from the sun as planet X, at what factor does the orbital period increase?
For the planet Y:
For planet X:
To know the factor of aumeto we compared 
with 
We know that the distance "a" from planet Y is k times larger than the distance from planet X to the sun. So:
So
Then, the period of Y increases by a factor of with respect to the period of X
Answer: $ 17.72
Step-by-step explanation:
Cost of soda = $2.15 , Cost of chicken = $8.77 , Cost of slice of cake = $4.10.
Total bill amount = (Cost of soda ) + (Cost of chicken) +(Cost of slice of cake)
= $ (2.15 + 8.77 +4.10)
= $ 15.02
Tip amount = 18% of Total bill amount
= 0.18 (15.02)
= $ 2.7036 ≈ $2.70
Entire bill = Total bill amount + Tip amount
= $ ( 15.02+2.70)
= $ 17.72
Hence, entire bill = $ 17.72
