A shopping mall parking garage charges $2 for the first half hour and $1.20 for each additional half hour (even if it is under 3

Neko [114]

You can park in the garage for 5 hours 30 minutes

Solution:

Given that, shopping mall parking garage charges $2 for the first half hour and $1.20 for each additional half hour (even if it is under 30 minutes)

Therefore,

Cost for first half an hour = $ 2

Cost for each additional half an hour = $ 1.20

Let "x" be the number of each additional half hour

Therefore, total cost to pay is given as:

Total cost = Cost for first half an hour + (Cost for each additional half an hour)(number of each additional half hour)

Total cost = 2 + 1.20x

Given you have $ 8 in cash

$8 = 2 + 1.20x\\\\1.20x = 8 - 2\\\\1.20x = 6\\\\x = \frac{6}{1.20}\\\\x = 5$

Total hours parked = first half an hour + 5

Thus you can park in the garage for 5 hours 30 minutes

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car’s average acceleration?

Dahasolnce [82]

Answer:

$a=4\ m/s^2$

Step-by-step explanation:

Given that,

The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.

We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,

$a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2$

So, the car's average acceleration is equal to $4\ m/s^2$ .

Milk is delivered to a chain of regional supermarkets once a week. If the weekly volume of sales in thousands of gallons is a ra

sleet_krkn [62]

Answer:

The chain of supermarkets must order 428.1 gallons of milk.

Step-by-step explanation:

Let's define the random variable X.

X : ''Weekly volume of sales in thousands of gallons''

X is a continuous random variable.

The probability density function for X is

$f(x)=7(1-x)^{6}$ when 0 < x < 1

$f(x)=0$ Otherwise.

Let's denote as ''a'' to the quantity of milk for the question.

We are looking for :

$P(X>a)=0.02$

$P(X>a)=\int\limits^1_a {f(x)} \, dx$

$P(X>a)=\int\limits^1_a {7(1-x)^{6}} \, dx$

$P(X>a)=(1-a)^{7}$

$(1-a)^{7}=0.02$

$a=1-\sqrt[7]{0.02}$

$a=0.4281$

a is in thousands of gallons, therefore the chain of supermarkets must order

428.1 gallons of milk in order to satisfy the question.
