Answer:
Step-by-step explanation:
Neptune is about 2,700,000,000 miles from Earth.
Mercury is about 135,000,000 miles from Earth.
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. The power is the number of decimal places you move.
1) 2,700,000,000 = 2.7 x 
135,000,000 = 1.35 x 
2)
You can see there is only one extra 0 on top, the rest will cancel so you have:
It's 20x farther to Neptune from Earth, than it is to Mercury from Earth.
Answer:
Step 1: Fill three gallon jug
Step 2: Pour the water from the three gallon to the five gallon jug
Step 3: Refill three gallon jug
Step 4: Pour three gallon jug into five jug until full (this leaves one gallon in the three gallon tank.
Step 5: Dump out the water in the five gallon jug
Step 6: Pour the 1 gallon of water into the five gallon jug
Step 7: Refill the 3 gallon jug
Step 8: Pour the 3 gallons into the five gallon jug (3 + 1 = 4)
Step 9: Place jug on scale.
Hope this helps!
Answer:
Step-by-step explanation:
y ∞ x/m
y = kx/m
Where k is the constant of proportionality
A. k = ym/x
y=5 when x=7 and m=4
k = (5×4)/7
k = 20/7
y = 20x/7m
B)the value of when x=2and m=2
y = 20x/7m
y = (20×2)/(7×2)
y = 40/14
y = 20/7
y = 2 6/7
C. The value of m when y=2 and x=4
y = 20x/7m
7ym = 20x
m = 20x/7y
m = (20×4)/(7×2)
m = 80/14
m = 40/7
m = 5 5/7
Answer:
complete the pattern 1,2,4,8, 10 and 12 and 14
