Answer:

200 minutes

Step-by-step explanation:

So we know that the speed is 92 km/h for the first car and 68 km/h for the second car. We do not know the time, but we do know that we need to convert it into minutes. The time for both cars would be x/60. Now we multiply speed by time and get distance. The first car would be 92 x/60 and the second would be 68 x/60, now we cross multiply and make an equation. 92x/60 - 68x/60 = 80, 24x = 80, x=200 minutes.

tigry1 [53]

Answer:

The answer is "58th %".

Step-by-step explanation:

2.4 Mbps in the sort data set is the 30th data point. Therefore 29 numbers out of 50 are less than 2.4 Mbps.

=\frac{29}{50} = 0.58 =58\%\\\\

The X-th percent is just the same as x% below the percent and thus 2,4 Mpbs corresponds to a 58th percent.

bazaltina [42]

Answer:

5.1

Step-by-step explanation:

Compounded Annually:

A=P(1+r)^t

A=P(1+r)  

t

 

A=27200\hspace{35px}P=20000\hspace{35px}r=0.062

A=27200P=20000r=0.062

Given values

27200=

27200=

\,\,20000(1+0.062)^{t}

20000(1+0.062)  

t

 

Plug in values

27200=

27200=

\,\,20000(1.062)^{t}

20000(1.062)  

t

 

Add

\frac{27200}{20000}=

20000

27200

​  

=

\,\,\frac{20000(1.062)^{t}}{20000}

20000

20000(1.062)  

t

 

​  

 

Divide by 20000

1.36=

1.36=

\,\,1.062^t

1.062  

t

 

\log\left(1.36\right)=

log(1.36)=

\,\,\log\left(1.062^t\right)

log(1.062  

t

)

Take the log of both sides

\log\left(1.36\right)=

log(1.36)=

\,\,t\log\left(1.062\right)

tlog(1.062)

Bring exponent to the front

\frac{\log\left(1.36\right)}{\log\left(1.062\right)}=

log(1.062)

log(1.36)

​  

=

\,\,\frac{t\log\left(1.062\right)}{\log\left(1.062\right)}

log(1.062)

tlog(1.062)

​  

 

Divide both sides by log(1.062)
