A rental car company charges drivers a flat fee to rent a car plus $0.25 for each mile they drive. If a driver pays
$100 and drives 160 miles, which equation can he use to find his total cost y in terms of the number of miles
driven x? SELECT ALL THAT APPLY
y = 25.2 + 100
y = .25x+ 140
y = .25x + 160
y - 100 = 25(x – 160)
0.25x + 100y = 160
25x – y = 14000

Answers

Answer: y-100= 0.25(x-160)

Step-by-step explanation:

Given: Charge per mile = $0.25

Total amount driver pays = $100

Number of miles he drove = 160 miles

Total cost = Flat fee +  ( Number of miles he drove) (Charge per mile) ...(i)

i.e. 100= Flat fee +  (160)(0.25)

⇒ Flat fee = 100 - (160)(0.25)

If y= total cost , x= number of miles, then

y= ( 100 - (160)(0.25))+ (x)(0.25)  [Substitute value of flat fee in (i)]

⇒ y= 100 - (160)(0.25)+ (x)(0.25)

⇒ y-100= (x)(0.25)- (160)(0.25)

⇒  y-100= 0.25(x-160)

Hence, the required equation:  y-100= 0.25(x-160)

Emily read 24 fiction books and 2 nonfiction books. What is the ratio of the number of fiction books she read to the total number of books that she
read?

Answers

Answer:

12:1 or 1:12

Step-by-step explanation:

For every 1 non fiction there is 12 fiction or for every 12 fiction there is 1 non fiction

The required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.

Given that,
Emily read 24 fiction books and 2 nonfiction books.
To determine the ratio of the number of fiction books she read to the total number of books that she read.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of fiction books  = 24
number of nonfiction books = 2
Total number of books = 24 + 2 = 26
The ratio of a fiction book to the total number of books,
= 24 / 26
= 12 / 13

Thus, the required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.

What is a polynomial?

An algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).

Given, P(x) is a polynomial. Here are a few values of P(x).

P(-6) = 3, P(-4) = -1, P(4) = 2, and P(6) = -5

The remainder theorem says that:

“When a polynomial p(x) is divided by (x−a), the remainder is p(a).

Since, p(6) is -5 and p(-4) is -1

Thus, the remainder when P(x) is divided by (x – 6) is -5

the remainder when P(x) is divided by (x + 4) is -1

Therefore, When Polynomial P(x) is divided by (x -6) and (x +4) the reminders would be -5 and -1 respectively.
