<h3>Answer: 1728 dollars</h3>

==========================================================

Explanation:

1 yard = 3 feet

We'll divide by 3 to convert from feet to yards

27 feet = 27/3 = 9 yards
18 feet = 18/3 = 6 yards

The basement is 9*6 = 54 square yards in floor area.

At $32 per square yard, the total cost to carpet the floor is 32*54 = 1728 dollars.

Drag each part of the equation to categories it as a term or a coefficient in the expression. Parts that are neither a term nor

faust18 [17]

Answer:

In the given expression:

Term = $x , x$

Coefficient= $-2, (\frac{3}{4})$

Neither one = 5

Step-by-step explanation:

Here, the given expression is : $-2x+\frac{3}{4} x +5$

Now, in the polynomial of the form $ax^{2} + bx + c$

All the x terms involving any powers of x are 'TERM'

Like $x^{2} , x$

All the co efficient of the x in the polynomial are called 'Co -efficient.

Here, a , b are co efficient.

The terms in the polynomial which are neither coefficient nor terms are called 'Constants' . Here, c is constant.

Now, in the given expression:

Term = $x , x$

Coefficient= $-2, (\frac{3}{4})$

Neither one = 5

The half-life of carbon-14 is 5,730 years. Assuming you start with 100% of carbon-14, what is the expression for the percent, P(

vodomira [7]

The general expression would be:
$P(t) = (\frac{1}{2})^{ \frac{t}{5730} }$
In an organism that is 20,000 years old (t = 20000), we would expect:
$P(t) = (\frac{1}{2} )^( \frac{20000}{5730} ) = 0.08898$
This menas there would be around 8.898% of carbon-14 remaining in the organism.

A movie theater has a seating capacity of 289. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults.

torisob [31]

Answer:

Number of children in theater = 94

Number of students = 46

Number of adults in theater= 47

Step-by-step explanation:

Total seating capacity in the theater = 187

Let us assume the number of students in the theater = m

and assume the number of children in the theater = 2k

So, the number of adults in theater = Half of number of children = 2k/2 = k

⇒ Number of ( Adults + Children + students) = 187

⇒ k + 2k + m = 187, or 3k + m = 187
