FIRST PERSON TO ANSWER GETS BRANILYEST
Veseljchak [2.6K]

Car A                               Car B

d=rt                                  d = rt

d = ra * 2.4                        d = rb 4

ra = rb+22

distances are the same so set the equations equal

ra * 2.4 =rb *4

substitue in  for ra

(rb+22) 2.4 =rb *4

distribute

2.4 rb +52.8 = 4 rb

subtract 2.4 rb from each side

52.8 = 1.6 rb

33 = rb

Car b travels at 33 miles per hour

Car a = 33+22

Car a = 55 miles per hour

Simplify 4sqrt(6) / sqrt(30) by rationalizing the denominator.
daser333 [38]
Given question is 4√6/√30
by rationalizing the denominator
4√6x√30/√30x√30
= 4√6x30/√30²
=4x√180/30 (i)
by solving the √180
√180=6√5
putting the value of √180 in (i)
=4x6√5/30
=24√5/30
=4√5/5 is the right answer.

What is 2 3/8 as an improper fraction?<br><br> Give answers, please.
m_a_m_a [10]

To convert a mixed fraction into an improper fraction, we must follow some steps.

First, we take the whole part and multiply it by the denominator of the fraction.

In this case, we take 2 and multiply it by 8.

Now we add the numerator:

16+3=19

The denominator stays the same:

\frac{19}{8}

Hope it helps! :)
