The total cost of renting the car for 6 days and driving 350 miles is $358.75 .

What is renting car?
An organisation known as a car rental, hire car, or car hire agency lends out cars to the general public for brief periods of time, typically from a few hours to a few weeks. Usually situated close to airports or busy city centres, it is frequently structured with a number of local branches that let customers return vehicles to multiple locations. A website that allows online reservations is sometimes added on top of this.
Car rental businesses generally cater to customers who need a short-term vehicle, such as those who don't own their own car, tourists who are out of town, or owners of damaged or totaled vehicles who are awaiting repairs or insurance settlement.

The cost of renting the car is $35 for each day .
And for each mile the car is driven we have to pay 42.5 cents .
Therefore 6 days the rent is = $35 x 6
= $210

And for 350 miles we have to pay = 350 x 42.5 cents
= 14875 cents = $148.75
In total $ 358.75

Answer:

18.25%

Step-by-step explanation:

730/4000 = 0.1825

The number of phone calls that Karen can be said to have received in these evenings are: 30 , 80 , and 20 calls

Wr have x, y , z as the number of phone calls that have been received

Such that

x + y + z = 130

On the second day she received 4 calls more than the 3rd day

y = 4z

On the first evening she had 10 more calls than the last

x = 10 + z

We have to substitute the equations in the first equation

10 + z + 4z  + z = 130

10 + 6z = 130

6z = 120

divide through by 6

z = 20

Then x = 10 + 20

x = 30

y = 4z

= 4 x 20 = 80

Therefore on the first day the phone call was 30 minutes, the second day was 80  and the third was 20

To check, 20 + 30 + 80 = 130. the solution is correct

The equation of the line is x + 3y = 2

Linear equations are equations that have constant average rates of change.

The given parameters are

Slope, m = -1/3

Points (x, y) = (1, 1/3)

A linear equation is represented as

y = slope * (x - x₁) + y₁

Where

(x₁, y₁) = (1, 1/3)

Substitute (x₁, y₁) = (1, 1/3) and Slope, m = -1/3 in the equation y = slope * (x - x₁) + y₁

So, we have

y = -1/3* (x - 1) + 1/3

Multiply through by 4

So, we have

3y = -(x - 1) + 1

Remove the brackets

3y = -x + 1 + 1

So, we have

x + 3y = 2

Hence. the linear equation is x + 3y = 2

A function can be defined as a law, rule or expression that shows the relationship between two known variables:

Given the function:

h(t) = -16t² + 96

Where;

To determine the maximum height in feet that the ball reached, we have to substitute the value of t as

We have:

h(1) = -16(1)² + 96

expand the bracket

h = -16 + 96

Add the values

h = 80 feet

The time it took the ball to stay in the air would be 1 second, this is so because the ball reached it maximum height as t = 1 sec

the total number of students in class is given by the equation x - 1 / 2 x - 1 / 4 x - 1 / 7 x = 3 and is equal to 28.

Let the total number of students be x

Mathematics = 1 / 2 x

natural philosophy = 1 / 4 x

Silence = 1 / 7 x

Remaining = 3

So, we get the equation as:

x - 1 / 2 x - 1 / 4 x - 1 / 7 x = 3

(28 x - 14 x - 7 x - 4 x) / 28 = 3

3 x / 28

x = (3 × 28) / 3

x = 28

Using system of equation, the solution shows that it will take 50 weeks before Jacob and Diego will be tied in the race to complete community service hours for scouting.

As given,

let us assign the unknown quantity (number of weeks) a variable x.

Jacob plans to devote 5 hours per week from now onwards. Hence his volunteer hours will cumulate to 5x+50 as he has already completed 50 weeks.

Diego plans to devote 6 hours per week from now onwards. Hence his volunteer hours will cumulate to 6x.

For Jacob and Diego to tie in the race, their volunteer hours should be equal.

Solution of the  system of equation is given by:

6x = 5x+50

=> 6x-5x = 50

=> x = 50
