Answer:
625 cm3
Step-by-step explanation:
Formula V1 * P1 = V2 * P2
V1 = 450 cm3
P1 = 125 kPa
P2 = 90 kPa
V2 = ?
V2 = (V1 * P1) / P2
V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3
Answer:
-16p³ + 48p² - 16p
Explanation:
In order to simplify the given expression, we need to multiplied 8p with (-2p²+6p-2)
8p*(-2p²+6p-2)
we need to distribute 8p over the brackets or parenthesis.
=8p*(-2p²) + 8p*(6p) + 8p*(-2)
= 8*(-2)*p*p² + 8*6p*p + 8*(-2)* p
= -16p³ + 48p² - 16p
We can't simplify it more, so that's the final answer.
I hope it's help.
Answer:
Adults=8
Childrens=2
Seniors=2
Step-by-step explanation:
Children $4
Adults $6
Seniors $5
There are an equal number of seniors and children.
The entire group spent a total of $66.
If 11 adults attended, the total amount will be $66 and the number of senior and childrens will be the same, 0. But this is not possible because the statement says that childrens and seniors are part of the group.
If we add the charges of childrens and seniors is equal to $9.
Assuming that the group has 2 childrens and 2 seniors the add is equal to:
Now we substract the result from the total amount:

48 is multiple of 6, this means we have in the group 8 adults, 2 childrens and 2 seniors.
Answer:
6(x+2)=66
6x+12=66 -12
6x= 54 :6
x=9
