Answer:
salini -= 5 years
mother = 40years
Step-by-step explanation:
then you equate the values of x
The answer should be 25.64$
You multiple that by 8% and then what you get out of it you add on to what you got as the total .
Answer:
$1200
Step-by-step explanation:
First we need to find 25% of 5,000, which is 5,000*.25=1250
Then we need to reduce 50 from 1250 which is 1250-50=1200.
Hope this helps!
Answer:
• $250
,
• y=200+50x
,
• Graph A
,
• Yes
Explanation:
(a)Han cellphone's plan costs a fixed fee of $200 and an extra $50 per month.
Therefore:
(b)If Han uses the phone for x months
Extra Cost = 50x
Therefore:
(c)Since the number of months = x; and
Total cost for x months = y
When x=24
The graph that shows the cost of the cell phone plan over a period of two years using months as the units of time is Graph A.
(d)We see that the equation y=50x+200 has a proportional constant (50).
Another approach is to say that it is a linear equation.
Therefore, there is a proportional relationship between time and the cost of the cell phone plan.
Answer:
14,648 years
Step-by-step explanation:
The amount remaining is ...
1 - 0.83 = 0.5^(t/5730) . . . . . . . half-life equation
log(0.17) = (t/5730)log(0.5) . . . . take the log of both sides
t = 5730·log(0.17)/log(0.5) ≈ 14,648
The approximate age of the bones is 14,648 years.
