Answer:
A = 0.75 gram or 1 gram
Step-by-step explanation:
The half-life of carbon 14 is years. How much would be left of an original -gram sample after 2,292 years? (To the nearest whole number).
We can use the following formula for half-life of 
to find out how much is left from the original sample after 2,292 years:
where:
<em>A</em> is the amount left of an original gram sample after <em>t</em> years, and
is the amount present at time <em>t</em> = 0.
The half-life of is the time <em>t</em> at which the amount present is one-half the amount at time <em>t </em>= 0.
If 1 gram of is present in a sample,
Solve for A when t = 2,292:
Substituting = 1 gram into the decay equation, and we have:
A = 0.75 g or 1 g
The LCM is 210
70×2=210
14×15=210
30×7=210
The answer is A.
Speed = distance / time
Speed = (4*400) / (6*60) (6*60 to turn minutes to seconds)
Speed = 1600 / 360
Speed = 4.44
Velocity = displacement / time
since she is running in a circle, she stops where she started making he displacement 0
Velocity = 0 / 6*60
Velocity = 0
7/8 x = 21
7x = 21×8
7x = 168
x = 24
Answer:
$137.75
Step-by-step explanation:
question is 'what is 5.8% of 2375'
'what' means assign a variable
'is' means an equal sign
'of' means to multiply
p = .058 x 2375
p = 137.75
*You could do the following: p = 5.8 x 2375 and get 13775 but you have to remember to move the decimal point two places to the left
