Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?

A.

5 miles

B.

158 miles

C.

300 miles

D.

453 miles

Answers

Answer: D. 453 miles .

Step-by-step explanation:

Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.

At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour [1 hour = 60 minutes],

Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]

[tex]=458-5=453\ miles[/tex]

Jessica is 453 miles from her home after 5 minutes she began returning home.

Hence, the correct option is D. 453 miles .

Paul buys 5 bags of chips and 9 bags of pretzels for $16.95. Ian buys 1 bag of chips and 1 bag of pretzels for $2.55. Find the cost of one bag of chips and one bag of pretzels.

Answers

Answer: The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Step-by-step explanation:

Let x= Cost of one bag of chips

y= Cost of one bag of pretzels.

As per given, we have

5x+9y=16.95 ...(i)

x+y=2.55 ...(ii)

Multiply 5 to (ii), we get

5x+5y=12.75 ...(iii)

Eliminate (iii) from (i), we get

[tex]4y=4.2\\\\\Rightarrow\ y=1.05[/tex]

Put value of y in (ii), we get

[tex]x+1.05=2.55\\\\\Rightarrow\ x=2.55-1.05=1.5[/tex]

Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

When the Mongols invaded Moscow in the thirteenth century, the Russians adapted the idea,adding spices and onions. The dish, eventually made its way from Russia to the port town of Hamburg, Germany, where it was adapted further.
