A hotel with 200 rooms has two types of rooms, and when it is completely booked, the hotel earns $18,250. Double rooms rent for
Mkey [24]

A) S + D = 200

B) 85 S + 110 D = 18,250   we multiply A) by -85

A) -85 S -85 D = -17,000  then we add to B) and get

25 D = 1,150

Double Bed Rooms = 46

Single Bed Rooma = 154

*************************************************

Double Check

46 * 110 = 5,060   154 * 85 = 13,090

Total = 18,150

Which expressions are equivalent to (2 Superscript 5 Baseline) Superscript negative 2? 2–10 and StartFraction 1 Over 20 EndFract
Serggg [28]

Answer:

\frac{1}{2^{10}} \ and\ \frac{1}{1024}

Step-by-step explanation:

Given

(2^{5})^{-2}

Required

Find the equivalent;

To find the equivalent of the given expression, we make use of laws of indices;

Using the following law of indices;

(a^m)^n = a^{m*n}

So;

(2^{5})^{-2} becomes

(2^{5})^{-2} = 2^{5*-2}

(2^{5})^{-2} = 2^{-10} ------------ This is one equivalent

Solving further;

Using the following law of indices;

a^{-m} = \frac{1}{a^m}

So;

(2^{5})^{-2} = 2^{-10} becomes

(2^{5})^{-2} = \frac{1}{2^{10}}

2^10 = 1024

Hence;

(2^{5})^{-2} = \frac{1}{1024}

Conclusively; the equivalents of (2^{5})^{-2} are \frac{1}{2^{10}} \ and\ \frac{1}{1024}

At what rate does a payment plan for $1,500 accumulate $450 interest after 6 years?
Lisa [10]

Answer:

At a rate of 5%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question:

Payment plan for $1500 means that P = 1500

$450 interest after 6 years means that E = 450, t = 6

We have to find the rate I. So

E = P*I*t

450 = 1500*I*6

I = \frac{450}{1500*6}

I = 0.05

At a rate of 5%.
