If Michael is bike riding at a speed of 4 miles an hour you would multiply 4 miles by the hour
So it would be x times y
0x4=0
1x4=4
2x4=8
3x4=12
4x4=16
5x4=20
9x4=36
1/2x4=2
Answer:
Below.
Step-by-step explanation:
If the sum of any 2 sides are less than or equal to the third side then there's no triangle
1. N0 because 4 + 5 < 10
2. YES
3. NO because 2 + 3 = 5.
Answer:
All real numbers less than 0
Step-by-step explanation:
I think it's this one because greater than 0 is wrong
Half life means exactly 1/2 of what's left decays
example
if yo has 16grams
if half life is 1 hour, after 1 hour, 8g is left
after another hour, 4g is left
after another your, 2g is left
etc
so find how many half lifes have elapes
so
the amount left after n halflives when you start with P amount is
A=P(1/2)^n
5hr=60*5=300mins
300/30=10
10 half lifves
P=1500
n=10
A=1500(1/2)^10
A=375/256
A≈1.46484g
about 1.5g left
