Answer:

a)   s=482moh

b)  s'=9mph

Step-by-step explanation:

From the question we are told that:

Distance d=3930mi

Time of flight T=8hr

Flight back T_b=8.3hr

Generally the equation for Time for flight with jet steam is mathematically given by

T=\frac{d}{s+s_1}

8=\frac{3930}{s+s'}

s+s'=491.3 ....equ1

Generally the equation for Time for flight against jet steam is mathematically given by

T=\frac{d}{s-s_1}

8.3=\frac{3930}{s-s_1}

s+s'=473.5......equ 2

Solving equ 1 and equ 2 simultaneously

s+s'=491.3

s+s'=473.5

Therefore

s=482moh

s'=9mph

There are 48 DVDs of comedies and dramas on the shelf. If 25% of the DVDs are comedies, how many are dramas?
Mazyrski [523]

There are 36 drama DVD's

<em><u>Solution:</u></em>

Given that there are 48 DVD's of comedies and dramas on shelf

25 % of DVD's are comedies

To find: number of drama DVD's

Total number of dvd = 48

Number of comedy dvd = 25 % of 48

Let us find 25 % of 48

\rightarrow 25 \% \text{ of } 48\\\\\rightarrow 25 \% \times 48\\\\\rightarrow \frac{25}{100} \times 48\\\\\rightarrow 0.25 \times 48 = 12

Thus, number of comedy dvd = 12

Thus we get,

number of drama DVD's = Total number of dvd - number of comedy dvd

number of drama dvd = 48 - 12 = 36

Thus there are 36 drama dvd's

The cost of a car rental is twenty-five dollars a day plus ten cents a mile. What is the total cost, in dollars, if the car is r
Fudgin [204]

Answer:

The total cost is D) $141

Step-by-step explanation:

To solve we can use the equation: y=25d+0.10m

d= number of days  m= number of miles

We know both of these values so we can plug them in and solve.

y= 25(3) + 0.10(660)

y= 75 + 66

y = 141

Kryger [21]

Answer:

x^3-8

Step-by-step explanation:

apply the inverse properties of logarithmic and exponential functions to simplify  

- 8 + e^{lnx^3}

Inverse property of log says that

e^{ln(x)=x

we apply this property in our problem. ln has same base 'e' . so ln and e gets cancelled

e^{ln(x^3)=x^3

- 8 + e^{lnx^3}

- 8 +x^3

x^3-8
