Answer:

The area of the room is 125 square feet because 12.5 times 10=125 square feet. As a result, you will spend $187.5 for it cost $1.5 to buy one square foot of carpet, and now we need 125 square feet to cover the room which 125 times 1.5 to get 187.5. Hope it help!

Answer:

$C.\ Perimeter = 48 * 18$

Step-by-step explanation:

Given

See attachment for her sketch

Required

Which equation do not represent the perimeter

From the attached sketch:

$L =18in$ --- Length

$W =48in$ --- Width

Perimeter (P) is calculated as:

$P = 2 * (L + W)$

This gives:

$P = 2 * (18 + 48)$ ---- This represents (A)

Open bracket

$P = 2 * 18 + 2*48$ ---- This represents (B)

In algebra:

$2 * a$ means $a+ a$

So, the expression becomes

$P = 18 + 18 +48 + 48$ --- This represents (D)

<em>This implies that (C) does not represent the perimeter</em>

Write a rule for the nth term of the sequence.

Helga [31]

Answer:

The rule for given sequence is: a_n = -27+16n

And the 100th term is: 1573

Step-by-step explanation:

Given sequence is:

-11, 5, 21, 37, 53, ...

Here

$a_1 = -11\\a_2 = 5\\a_3 = 21\\a_4 = 37$

First of all, we have to find if this is an arithmetic sequence

For that purpose, the common difference has to be found. Common difference, denoted by d, is the difference between consecutive terms of an arithmetic sequence

So,

$d = a_2 -a_1 = 5-(-11) = 5+11 = 16\\d = a_3 -a_2 = 21-5 = 16\\d = a_4-a_3 = 37-21 = 16$

As the common difference is same, the sequence is an arithmetic sequence

General rule for arithmetic sequence is:

$a_n = a_1+(n-1)d$

Putting values

$a_n = -11+(n-1)(16)\\a_n = -11+16n-16\\a_n = -27+16n$

For 100th term,

Putting n=100

$a_{100} = -27+16(100)\\a_{100} = -27+1600 = 1573$

Hence,

The rule for given sequence is: a_n = -27+16n

And the 100th term is: 1573

Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At su

Kipish [7]

Answer:

7 hours

Step-by-step explanation:

We are given that

At sunset, the temperature=-5 degrees Fahrenheit

Each hour, temperature falling=2degrees Fahrenheit

We have to find time taken to reach the temperature -19° F.

Let x be the time time taken to reach the temperature -19° F

According to question

$-5+x(-2)=-19$

Where we taking 2 negative because temperature decreases.

$-5-2x=-19$

$-5+19=2x$

$14=2x$

$x=\frac{14}{2}$

$x=7$

Hence, it will take 7 hours for the temperature to reach -19° F.

Slew lines are lines that don’t intersect (or cross over one another) and don’t lie on the small plane. So for an example, if you pick a line on the floor and a line on one of the walls, they would be skew lines because they are on different planes. It they also can’t intersect each other.
