Answer:

The correct answer will be "60 min/hour".

Step-by-step explanation:

At time 2:00 PM

A car reads = 30 mi/h

At time 2:20 PM

A car reads = 50 mi/h

Now,

At time 2:00 PM

t = 0

At time 2:20 PM

t = $\frac{1}{3}$

$v(0)=30$

$v(\frac{1}{3})=50$

For MVT,

$v'(c)=\frac{v(\frac{1}{3} -v(0))}{(\frac{1}{3} )}$

$=\frac{20}{\frac{1}{3} }$

$=60 \ min/hour$

Whats 20 inches and 7 feet as a fraction in simpalist form

Rudik [331]

4 4/7 feet is it's simplest form because 20 I'm chea equal 1.67 feet and 7 feet equals 84 inches so do 20 × 4 = 80 then you would have 4 left over and turn that into 4/7

Consider the equation below.

Eduardwww [97]

Answer:

The equation has no solutions .

Step-by-step explanation:

Given as :

<u>The linear equation is </u>

$\dfrac{3}{4}$ (24 -16 x) = $\dfrac{-2}{3}$ (18 x -27)

Or, $\dfrac{3}{4}$ ×24 - $\dfrac{3}{4}$ × 16 x = $\dfrac{-2}{3}$ × 18 x - $\dfrac{-2}{3}$ × 27

Or, $\dfrac{3}{4}$ ×24 - $\dfrac{3}{4}$ × 16 x = $\dfrac{-2}{3}$ × 18 x + $\dfrac{2}{3}$ × 27

Or, $\frac{3\times 24}{4}$ - $\frac{3\times 16 x}{4}$ = $\frac{-2\times 18 x}{3}$ + $\frac{2\times 27 x}{3}$

Or, 3 × 6 - 3 × 4 x = - 2 × 6 x + 2 × 9

Or, 18 - 12 x = - 12 x + 18

Or, 18 - 18 = - 12 x + 12 x

or, 0 = 0

∵ The linear equation has no variables , so the equation has no solution

Hence,The equation has no solutions . Answer
