Suppose that a bored student wants to go to a restaurant for lunch, but she only has an hour in which to go, eat, and get back i
Blababa [14]

Missing information

Take local speed ad 30 mph and express your answer in miles

Answer:

7.5 miles

Step-by-step explanation:

Time for lunch is 1 hour but once will wait for 30 minutes before served and eat.

Out of 1 hour, 30 mins is for service and eating to mean time to get from work to restaurant, to and fro is the other 30 mins

Since 30 mins is for to and fro, then one way direction takes 15 mins.

Speed, s=d/t and distance d=speed*time

Given local speed of 30 mph and time as 15 mins,

To convert minutes to hours, we divide it by 60 hence the distance is

30*15/60=7.5 miles

Therefore, the student can go to a restaurant that is 7.5 miles from the office.

What is an equation of the line that passes through the points (6, -3)and (−6,−5)?
Lady_Fox [76]

Answer:

y = 1/6x -4

Step-by-step explanation:

First find the slope

m= ( y2-y1)/(x2-x1)

m=(-5 - -3)/( -6 -6)

   = (-5+3)/ (-6-6)

       = -2/-12

       = 1/6

The slope intercept form is

y= mx+b where m is the slope and b is the y intercept

y = 1/6 x +b

Substitute a point into the equation

-5 = 1/6(-6) +b

-5 = -1+b

Add 1 to each side

-4 = b

y = 1/6x -4

Artyom0805 [142]

Answer: Kriz should pay $50,100 at the end of the term.

Step-by-step explanation:

If the interest is compunded quarterly, then the accumulated amount after t years will be:

A=P(1+\frac{r}{400})^{4t} , where P= principal value , r = rate of interest .

Given: P= 50,000 , r= 5% = 0.05, t= 4 years

Then,

A=50000(1+\dfrac{0.05}{400})^{4(4)}\\\\= 50000(1+0.000125)^{16}\\\\=50000(1.000125)^{16}\\\\=50000(1.002)\\\\=\$50,100

Hence, Kriz should pay $50,100 at the end of the term.
