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%.
