Answer:
The brainliest!
Step-by-step explanation:
c= 7/6k- 17(7/6)
6/7c = k - 17
k = 6/7c+17
The answer is 74,000 years.

amount remaining, where n is a number of half-lives.
<span>Decimal amount remaining is 0.00012 (= 0.012%). Let's calculate number
of half-lives.</span>

⇒ n ≈ 13
<span>
Now we know that number of half-lives is 13.</span>
Number of half-lives is quotient of total time elapsed and length of
half-life.<span>
<span>So, total time elapsed is a product of length of
half-life (5,730 years) and number of half-lives (13). Since 5,730 years × 13 =
74,490 years, then the person died 74,000 years ago (rounded to the nearest thousand).</span></span>
Answer:
$5.75
Step-by-step explanation:
Joshua paid $9.10 for a bag and has $16.25 left
Now let's find out how much Joshua had before spending on a bag. To do this, we simply sum up the cost of the bag and how much Joshua had lefyt
9.10 + 16.25
=$25.35
Since Joshua and Shopping had the same amount, Shuping also had $25.35
To get the cost of the pen, we subtract the amount Shuping had left after purchasing the pen
This gives;
25.35 - 19.60
=$5.75
Answer:
92.5km
Step-by-step explanation:
By cross multiplication you will get 2x=7.4x25.(cross multiply map scale = 2cm and 7.4 put them under each other and for the actual distance it's 25 km and X cross multiply and that's how u get 2x=7.4*25) now u will multiply 7.4*25 u will get 185 and then divide by 2 on each side so the x is left alone (2x/2=185/2) which will give you x=92.5km.
I tried my best to explain it
One angle = 360 / n
Let x be the angle and n be the number of sides.
x = 360 / n
nx = 360
now, let's use this:
(2n - 4 )*90 = 1260
2n - 4 = 1260 / 90
2n - 4 = 42 / 3
2n - 4 = 14
2n = 18
n = 9
x = 360 / 9
x = 40 degrees for each exterior angle
so the interior angle's measurement is 140 degrees
So 9 would be the answer
