What is 449/60 as a mixed number

1 answer:

6 0

$\dfrac{449}{60}=\dfrac{300+120+29}{60}=\dfrac{300}{60}+\dfrac{120}{60}+\dfrac{29}{60}\\\\=5+2+\dfrac{29}{60}=\boxed{7\dfrac{29}{60}}$

A car rental company rents cars for x dollars per day plus y dollars for each mile driven. Carlos rented a car for 4 days, drove

topjm [15]

Answer:

x = $20/day, y = $0.35/mile

Step-by-step explanation:

x = $/day, y = $/mile

4x + 160y = 136

1x + 240y = 104

You can solve by elimination or substitution.

Ramon uses models to compare two decimial he says 0.09 greater than 0.1 because 9>1 which of these explain ramon's mistake

Shalnov [3]

Answer:

Ramon's mistake was that he used whole numbers in comparison to decimals, which is not an accurate way to solve. Think about it this way, 0.1 is the tens place, 0.01 is the hundreds place. Which would be greater 100% of the time? The hundreds place, in decimal terms, the hundredths.

0.09 is greater than 0.1

Given: Lines a and b are parallel and line c is a transversal. Prove: Angle2 is supplementary to Angle8 Horizontal and parallel

kondaur [170]

Answer:

The correct option is;

Corresponding angles theorem

Step-by-step explanation:

Type of lines of lines a and b = Horizontal and parallel lines

The transversal to a and b = Line c

The angles between a and c labelled clockwise from the upper left quarter segment = 1, 2, 4 and 3

The angles between b and c labelled clockwise from the upper left segment = 5, 6, 8 and 7

Therefore, we have;

Statement ${}$ Reason

1. a║b, c is a transversal ${}$ Given

2. ∠6 ≅ ∠2 ${}$ Corresponding angles theorem

3. m∠6 = m∠2 ${}$ Definition of congruent

4. ∠6 is supp. to ∠8 ${}$ Definition of linear pair

5. ∠2 is supp. to ∠8 ${}$ Congruent supplement theorem

Corresponding angles are the angles located in spatially similar or matching corners of two lines that have been crossed by the same transversal. When the two lines having a common transversal are parallel, the corresponding angles will be congruent.
