Ace Truck leases its 10-ft box truck at $20/day and $0.50/mi, whereas Acme Truck leases a similar truck at $15/day and $0.55/mi.
Masja [62]

Answer:

a) f(x) = 0.5 \frac{dollars}{day} x + 20

g(x) = 0.55 \frac{dollars}{mi} x + 15

b) f(70)=0.5*70 +20 =55

g(70)= 0.55*70 + 15 =53.5

If we want to minimize the cost then we should rent the Acme Truck company.

Step-by-step explanation:

Assuming the following questions.

(a) Find the daily cost of leasing from each company as a function of the number of miles driven and sketch the graph of these functions.

For the Ace truck we know that leases its 10-ft box truck at $20/day and $0.50/mi. So then f(x) representing the daily cost is given by:

f(x) = 0.5 \frac{dollars}{day} x + 20

Where x represent the  number of miles driven

For the Acme Truck we know that leases a similar truck at $15/day and $0.55/mi, so then the g*x( representing daily cost would be given by:

g(x) = 0.55 \frac{dollars}{mi} x + 15

Where x represent the miles driven.

We can see the plot on the figure attached.

(b) Which company should you rent a truck from for 1 day if you plan to drive 70 miles and wish to minimize cost?

If we replace the value x=70 for both functions we got:

f(70)=0.5*70 +20 =55

g(70)= 0.55*70 + 15 =53.5

If we want to minimize the cost then we should rent the Acme Truck company.

What is the value of x in the equation 3x-4y=65, when y=4?
Softa [21]

Answer:

\boxed{ \bold{ \huge{ \boxed { \sf{x = 27}}}}}

Step-by-step explanation:

Given, value of y = 4

To find : Value of x

\sf{3x - 4y = 65}

plug the value of y

\dashrightarrow{ \sf{3x - 4 \times 4 = 65}}

Multiply the numbers : 4 and 4

\dashrightarrow{ \sf{3x - 16 = 65}}

Move 16 to right hand side and change it's sign

\dashrightarrow{ \sf{3x = 65 + 16}}

Add the numbers : 65 and 16

\dashrightarrow{ \sf{3x = 81}}

Divide both sides by 3

\dashrightarrow{ \sf{ \frac{3x}{3}  =  \frac{81}{3} }}

Calculate

\dashrightarrow{ \sf{ x = 27}}

Hope I helped!

Best regards! :D

There are 25 students in Mrs. Venetozzi's class at the beginning of the school year, and the average number of siblings for each
Rainbow [258]

Answer:

The new class average for number of siblings is 3 5/26 or 3.1923

Step-by-step explanation:

if the average is 3 siblings per student and there are 25 students, it means that we can calculate the number of siblings

25 * 3 = 75

we add the 8 new siblings and we also add the student

75 + 8 = 83

25 + 1 = 26

To find the new average of siblings per student, we divide the number of siblings by the number of students.

83 / 26 = 3 5/26

the new class average for number of siblings is 3 5/26 or 3.1923

Determine which of the following graphs is the graph of 8x + 9y - 72.
Fittoniya [83]

Step-by-step explanation:

To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.

Step 1: 8x + 9y - 72 = 0

Step 2: 8x + 9y = 72

Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C

Y-INTERCEPT (vertical line): ( \frac{c}{b} , 0 )

X-INTERCEPT (horizontal line): ( 0 , \frac{c}{a} )

Insert your numbers how it shows in the standard form equation and you should get something like this:

Y-INTERCEPT: ( \frac{72}{9} , 0 )

<em>Simplified Y-INTERCEPT: </em>( 8 , 0 )

X-INTERCEPT:  ( 0 , \frac{72}{8} )

<em>Simplified X-INTERCEPT: </em><em> ( 0 , 9 )</em>

<em />

Insert that into your graph and you should be able to get your answer.
