Answer:

8 years

Step-by-step explanation:

x years later type A and type B will have the same height

Type A = Type B: 10  + (8/12)*X  = 6 + (14/12)*X

multiply 12 each side

120 + 8x = 72 + 14x

14x - 8x = 120 - 72

6x = 48

x = 8

check: A: 10 x 12 + 8 x 8 = 184

            B: 6 x 12 + 14 x 8 = 184

An ac unit uses 3500 watts or power. If it runs for 10 hours each day and the utility company charges $0.13 per kWh, how much do
Helga [31]

Cost = (3500 W)·(1 kw/1000 W)·(10 hrs/day)·(30 day/month)·($0.13/kw-hr)

Cost = (3500·1·10·30·0.13 / 1000)·(W·kW·hr·da·$ / W·da·month·kw·hr)

Cost = <em> 136.50  $/month</em>

Does the decimal equivalent of p/q, where p and q are positive integers, contain only a finite number of nonzero digits?
Aleks [24]

A/B is a reduced fraction which can be represented as a terminating decimal if and only b is of the form 2^n5^n where m and n are non negative integers. For example: 7/250, the terminating decimal here is 0.028 as 250 as the denominator equals to 2*5^2.

According to the above, we must know whether the denominator have only 2-s and or 5-s as the prime factors. So,

Q = 8 = 2 ^3 = hence the denominator has only 2 prime factors. Fraction P/Q will be termed as terminated decimal which is sufficient.
