Answer:
the number of adult tickets sold is
x = 89
and , the number of student tickets sold is y = 178
Step-by-step explanation:
Let the number of adult tickets sold be x and number of student tickets sold be y !
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em> Total 267 tickets were sold
i.e, x + y = 267
x = 267 - y .... ( i )
Also, The number of student tickets sold was two times the number of adult tickets sold.
i.e, y = 2x ...... ( ii )
putting value of x from ( i ) in ( ii )
y = 2 ( 267 - y )
y = 534 - 2y
3y = 534
y = 534/3
y = 178
also, x = 267 - y
x = 267 - 178
x = 89
So, the number of adult tickets sold is
x = 89
and , the number of student tickets sold is y = 178
Answer: The amount of carbon-14 remaining after 4 years is 99.95 grams.
Step-by-step explanation:
Hi, to answer this question we simply have to substitute t=4 in the equation given and solve for c.
c= 100 (0.99988)^t
c =100 (0.99988)^4
c = 100 x 0.999520086
c= 99.95200864 ≅99.95 grams (rounded)
The amount of carbon-14 remaining after 4 years is 99.95 grams.
Feel free to ask for more if needed or if you did not understand something.
It is B because it can’t be A and it can’t be C and it can’t be D so my answer is B
-1/6 + 2/3 (9-3/4)-1/2
= -1/6 + 2/3 (33/4) -1/2
= -1/6 + 11/2 - 1/2
= 16/3 - 1/2
= 29/3
