You would multiply 90x7.8 to get the answer.
Step-by-step explanation:
9x10=90.
Answer:
d=3
Step-by-step explanation:
by using distance formula
d=√(x2-x1)²+(y2-y1)²
let the points be A(-3,2) B(0,2)
d=√(0--3)²+(2-2)²
d=√(+3)²+(0)²
d=√9
d=3
First Answer Is 15
Second Is 2
Answer:
An old bone contains 80% of its original carbon-14 in 1844.6479 years
Step-by-step explanation:
We know that
half life time of C-14 is 5730 years
so, h=5730
now, we can use formula

we can plug back h
and we get

An old bone contains 80% of its original carbon-14
so,
P(t)=0.80Po
we can plug it and then we solve for t





So,
An old bone contains 80% of its original carbon-14 in 1844.6479 years
Answer: 0
35X +14=3X +14
35X = 3X
35X-3X=0
32X = 0 divide both sides by 32
x=0
