Answer:
$99
Step-by-step explanation:
Cost of electricity per year= $165
Tax per month= 5%
Amount of tax paid per month= 5% of $165
= 0.05 × 165
= $8.25
Ella's family pays $8.25 tax per month
There are 12 months in 1 year
Ella's family will pay Ina year = $8.25 × 12
= $99
Ella's family will pay $99 tax for an entire year
Answer:
of the phones in office has both a speaker phone and a conference-call capability
Step-by-step explanation:
Since total number of phones in the office is not given, the answer will be "in that terms".
let it be x
So built in speaker phones is (1/4)x
Hence conference call phones would be (1/2)(1/4x) = (1/8)x
Hence "1/8th of the phones in office has both a speaker phone and a conference-call capability"
Answer:
Step-by-step explanation:
Simplifying the given expressions we proceed as follows:
(5sqrt3)^x
=5^x*(3^1/2)^x
=5^x*3^x/2
=5^x3^u
where u=x/2
(1/2)^(x-3)
=1/2^(x-3)
=2^-(3-x)
=2^u
where u=-(3-x)
9/3sqrt(3)
=3/(3)^(1/2)
=3(3)^(-1/2)
16/(3sqrt (2^x))
=1/3*(2^4*2^(-x/2))
=1/3*2^(4-x/2)
=1/3*2^u
where:
u=4-x/2
