Answer:
94
Step-by-step explanation:
Add units together. 87+93+102=282.
Divide total number by number of days. 282/3=94
Area = (h/2)(a +b)
where h = distance between the 2 parallel line segments and a and b are the lengths of these 2 line segments.
I don’t know what that is it’s probably 9999999
7978 years
Step-by-step explanation:
A = A02^(-t/hl)
where hl = half-life.
Dividing both sides by A0 and taking the logarithm, we get
ln(A/A0) = -(t/hl)ln2
or solving for t,
t= -(hl)ln(A/A0)/ln2
note that A/A0 = 0.38
t = -(5715 yrs)[ln(0.38)/ln2]
= 7978 years
Answer:
The answer is when they work 4 hours x=4
Step-by-step explanation:
510 + 80x = 650 + 45x
80x - 45x = 650 - 510
35x = 140
x = 140/35
x = 4 hours
