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.

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

x= \frac{-b+- \sqrt{ b^{2}-4ac } }{2a}

b = coefficient of x term = 5
a = coefficient of squared term = 1
c = constant term = 7

Using the values, we get:

x= \frac{-5+- \sqrt{25-4(1)(7)} }{2(1)} \\  \\ 
x= \frac{-5+- \sqrt{-3} }{2}

So, the correct answer to this question are option E and F

Ratling [72]
Are you saying that $1050 was the initial amount of money in the savings account? If so then you'd find 84% of 1050, which is 1050*.84. (.84 is the decimal version of 84%)

BRAINLIESTTT ASAP!! PLEASE HELP ME :)
Andrej [43]

Answer:

2017.

Step-by-step explanation:

The equation for the future sale of motorcycles

= 5.75(1.16)^t  where t is in years

For cars it is

3.5(1.25)^t

3.5(1.25)^t > 5.75(1.16)^t

(1.25)^t > (5.75/3.5) 1.16^t

t ln 1.25 > ln 1.64286 + t ln 1.16

t ln 1.25 -  t ln 1.16 > ln 1.64286

t (ln 1.25 - ln 1.16) > ln 1.64286

t > ln 1.64286 / (ln1.25 - ln 1.16)

t > 6.64 .

So the answer is in the year 2017.
