Answer: If 36/7 is one of the options, choose that one.

If the question involves an exponent, you should use the "caret" which is ^ found above the 6 on a keyboard. [Shift + 6]. That helps avoid confusion.

Step-by-step explanation: 7 is equal to 35/5 because 7×5=35

Add 1/5 and you end up with 36/5. A Common rational number.

7^(1/5) = the 5th root of 7. A very small irrational number!

Great Dish believes that it will need new equipment in 8 years. The equipment will cost $26,000. What lump sum should be investe

xenn [34]

Answer:

d. $10,234.80

Step-by-step explanation:

we are given

The equipment will cost $26,000

so, Amount is $26000

A=26000

should be invested today at 12%

r=12%=0.12

It is compounded semiannually

so, n=2

t=8

now, we can use formula

$A=P(1+\frac{r}{n})^{nt}$

now, we can plug values

$26000=P(1+\frac{0.12}{2})^{2\times 8}$

now, we can solve for P

$P=10234.80338$

The prices of houses in Tennessee have been on a steady incline for the last several years. If the average price of a house has

sveticcg [70]

Answer:

The average price of a house last year was = $124,423.96

Step-by-step explanation:

Let the average price of houses in Tennessee last year in dollars be = $x$

This year the increase percentage in average price was = 8.5%

The change in average price can be calculated in dollars as:

⇒ $8.5\%\ of\ \textrm{Last year average price}$

⇒ $0.085\times x$

⇒ $0.085x$

New increased average price in dollars can be calculated as:

$\textrm{Last year average price + Increase in average price}$

⇒ $x+0.085x$

⇒ $1.085x$

The new increased average price actually is = $135,000

So, we have,

$1.085x=135000$

Dividing both sides by 1.085

$\frac{1.085x}{1.085}=\frac{135000}{1.085}$

∴ $x=124423.96$

Thus average price of a house last year was = $124,423.96
