42 and 17 millionsth.....
bro which class question is this then I can help you with ur question
Hello from MrBillDoesMath!
Answer:
Choice E.
Discussion:
Assuming that n >=1, a(n) = 4n -1, then
a(10) = 4(10) - 1 = 39
but that doesn't match any of the answers...... hmm...
BUT
If you meant that a(n) = 4^(n-1), then
a(10) = 4^(10-1) = 4^9 = 262144
which is Choice E.
Thank you,
MrB
Answer:
The answer is 61.4 L
Step-by-step explanation:
Using the formula of cuboid, V = l×b×h, to find the total amount of water contained :
l = 120cm
b = 40cm
h = 15cm
V = 15×120×40
= 72 000cm³
= 72 L
It is given that she uses 10.6L for shower. Then calculate the remaining water by substracting 10.6L from the original amount of water :
remaining = 72 - 10.6
= 61.4 L
