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

Answer:

650,000÷10^3 = 650

7,000÷10^2=70

Step-by-step explanation:

The linear function passing through points (1,7) and (2.5, 1) is given by:

y = -4x + 11.

A linear function, in slope-intercept format, is modeled according to the rule presented below:

y = mx + b

In which the coefficients are described as follows:

For this problem, the two points that form the function are given as follows:

(1,7) and (2.5, 1).

The slope is given by change in y divided by change in x, hence it is given by:

m = (1 - 7)/(2.5 - 1) = -4.

Then:

y = -4x + b.

When x = 1, y = 7, hence we can find the intercept b of the function as follows:

7 = -4(1) + b

b = 7 + 4

b = 11.

Hence the equation is:

y = -4x + 11.

If we factor out -6 from the given expression, then we get the answer as -6(-3z + 5/2).

A factor may be defined as a number of another number which when divided by the other number leaves no remainder or it completely divides the other number. For example, 2 is a factor of 4 as when 4 is divided by 2 the remainder is zero. Now, we are given in the question that we need to factor -6 out of 18z - 15. In order to do that we divide and multiply -6 from the given expression. This can be represented as

-6 × (18z - 15)/(-6)

Further we get

-6 × (-3z + 15/6)

-6 × (-3z + 5/2)

which is the required value.

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

The question can be answered by simply following the rules of angles of geometry. The rule that follows here is:

Rule: Vertically opposite angles are equal i.e whenever two straight lines cross, they create two pairs of equal vertically opposite angles.

Because, both the angles given in the question are vertically opposite to each other

Therefore, angle 80 degree = angle 86 + X

i.e   80 = 86 + X

-->   80 - 86 = X

-->   -6 = X

The inequalities in interval notation are given below

What is an inequality?

An inequality in maths is a relationship that makes a non-equal distinction between two values as well as other mathematical expressions. It is most frequently used to compare the sizes of two digits on a number line. There are multiple formulae used to denote various types of inequalities:
(i) The symbol a < b indicates that a is less than b.

(ii) a > b indicates that a is bigger than b.

In either scenario, a and b are not equivalent. These are characterized as tight inequalities because a is either strictly less than or strictly bigger than b. Equivalence is not permitted. In contrary to rigorous inequalities, there are two forms of non-strict inequality relationships.

Answer:

Positive Slope, the graph interprets how much it costs to rent a canol per hour.

Step-by-step explanation:

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

The weakness of plotting a scatterplot is given below

What is a scatterplot?

A scatterplot (also known as a scatter plot, scatter graph, scatter chart, scattergram, or scatter diagram) is a form of plot or mathematical diagram that uses Cartesian coordinates to represent values for a collection of data for generally two variables. One more variable can be presented if the points are coded (color/shape/size). The data is represented as a collection of dots, with the value of one variable defining the horizontal axis and the value of the other variable determining the vertical axis. A scatterplot can be used when one continuous variable is within the experimenter's control and the other is reliant on it, or when both continuous variables are independent.

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
