So its asking you to find the gravity on earth relative to the gravity on mars.
Set up an equation to figure out the difference between the two gravities
x=.38
I don't know what constant of proportionality is in this context but a ball on mars would weigh .38 the amount that it does on earth.
Answer:
20 : 30
x : 7200
∴(20*7200)/30=4800
Step-by-step explanation:
20 pencils is to 30 seconds so x is to 7200(2 hours is seconds) then cross multiply and lastly divide 144000 by 30 to get the answer
Answer:
14x+6z
Step-by-step explanation:
distribute 2 into (4x-3z) and 3 into (2x+4z)
8x-6z+6x+12z
combine like terms
8x+6x=14x
12z-6z=6z
14x+6z
hope this helps
Answer:
There's 3 total decimal places in both numbers.
Ignore the decimal places and complete the multiplication as if operating on two integers.
1 9
× 2
+ 3 8
= 3 8 Rewrite the product with 3 total decimal places.
Answer = 0.038
Therefore:
0.19 × 0.2 = 0.038
