The monthly cost of 57 minutes calls is $12.55.
The monthly cost is $12.03 for 53 minutes and $ 13.59 for 65 minutes call
Therefore we have two points (53, 12.03) and ( 65, 13.59)
slope = (13.59 - 12.03)/ ( 65 - 53)
= 1.56/ 12
= 0.13
The intercept is
y = mx + c
12.03 = 0.13×53 + c
12.03 = 6.89 + c
c = 5.14
Equation:
cost = 0.13(minutes) + 5.14
= 0.13×57 + 5.14
= 7.41 + 5.14
= 12.55
Therefore the monthly cost for 57 minutes is $12.55.

What kind of numbers are −5 and 7?
-5 and 7 are real and rational numbers also they are integers.
What is a rational number ?Numbers which can be written in the form of p/q are rational numbers where q must not be zero.
According to the given question we have to determine what kind of numbers are -5 and 7.
In a most simple way we can say that - 5 is an negative integer and 7 is a positive integer.
But -5 can be written as -5/1 which is a rational number also and 7 can also be written as 7/1 so we can also say they are integers al well as rational numbers.Lastly they are real numbers as they don't have any imaginary part 'i' in it.

Use the graph of the line to answer the questions. what is an equation of the line in slope-point form? _____
How can the point-slope form be written in function notation?
_______
The slope-point form is y + 1 = (1/4) (x +2)
The function notation for the point-slope form is f(x) = -1 + (1/4) (x +2)
From the graph, we get two points (x₁, y₁) = (-2, -1) and (x₂, y₂) = (2,0)
Slope, m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{0 --1}{2--2}[/tex]
= 1/4
The slope-point form of a line is (y-y₁) = m(x-x₁), where (x, y) is the general point on the line, (x₁, y₁) is a given point on the line and m, the slope of the line.
So here the slope-point form of the line is,
(y- -1) = 1/4(x- -2)
⇒ y + 1 = (1/4) (x +2)
For the function notation, we put y = f(x) simply and write it as,
f(x) = -1 + (1/4) (x +2)

Hope it helpsSix friends each use $2-off coupons to but themselves a movie ticket. They spend a total of $42. What is the price of one movie ticket without coupon?
Modelling the situation, it is found the price of the ticket without the coupon is of $9 when all the six friends spent $ 42 to buy the tickets.
Total money spent by 6 friends on purchasing of the movie tickets = $ 42
So, the money spent for the purchase of 1 ticket will be calculated by dividing the $ 42 by 6.
So, cost of 1 ticket = 4 42 / 6 = $ 7
Coupon is of $2-off.
This means that with the coupon, $2 is subtracted from the ticket price.
So, price of ticket will be = $ 7 + $ 2 = $ 9.
Therefore, the price of the ticket without the coupons will be $ 9.

Answer: 1/4
Step-by-step explanation:
The easiest way to solve this is to make them all common denominators.
The common denominator for this problem is 24.
Change the denominators:
1/4 = 6/24
4/12 = 8/24
3/8 = 9/24
2/6 = 8/24
This way it is easier to see which one is smaller and closest to 0. In this case, it is 6/24 or 1/4 because 6/24 is the smallest out of all of them.

The days it would take to complete the building is 104 22/25 days.
How many days would it take to complete the building?A fraction is a non-integer that has a numerator and a denominator. The numerator is the number above. While the denominator is the number below. An example of a fraction is 1/4.
A mixed number is a number that has a whole number and a proper fraction. A proper fraction is a non-integer in which the numerator is less than the denominator. An example of a mixed number is 3 1/2.
The first step is to determine the total height of the office bulding = height of each floor x total number of floors
15 x 10 2/5
15 x 52/5 = 780 /5 = 156
The next step is to determine the floors left to complete the office building :
156 - 24 9/10 = 131 1/10 feet
The last step is to divide the feet that can be built each day by the number of floors needed to complete the builfing :
1311/10 ÷ 1 1/4
1311 / 110 ÷ 5/4
1311 / 10 x 4/5 = 104 days 44/50

Is the slope of a linear demand curve positive or nega-

The slope of a linear demand curve is negative
The demand curve's negative slope indicates that there is an inverse link between price and demand.
It is true that the demand curve's negative slope indicates an inverse link between price and quantity desired. According to the demand curve, demand declines as prices increase and rises as prices decrease.
This statement is false since it only applies to Giffen products, where the demand curve has a positive slope and a direct correlation between price and quantity desired.
Because unit requests rise when prices decrease and decline when prices rise, the demand curve often slopes downward (i.e., is negative). Demand increases when prices are low, but demand decreases when prices are high.

The set of ordered pairs that represents a function is the third option.
{ (4, 1), (-6, 6), (5, -2), (-4, 1)}
Which set of ordered pairs represents a function?
For a relation that maps elements x (inputs) into elements y (outputs), we will have ordered pairs of the form (x, y) that define the relation.
Now, a relation is only a function if input are only mapped to only one output.
For example, if you look at the first set of ordered pairs, you can see that the input x = -4 appears twice with two different outputs, then this relation does not represent a function.
For the second set the same thing happens for the input x = -8, and for the last set the same happens for the input x = -8
The only set where each input appears only once is the third one:
{ (4, 1), (-6, 6), (5, -2), (-4, 1)}
This relation represents a function, so this is the correct option.

Calculate the length of a chord of a circle of radius 26cm if the chord is 10cm from the center of the circle
Answer: see explanation
Step-by-step explanation:
The 10 cm distance is measured perpendicularly to the chord, forming a right angle and bisecting the chord. Thus half of the chord, the segment from the center of the chord, and a radius to the end of the chord form a right triangle. The hypotenuse is 26 cm and one leg is 10 cm, so the other leg is given by the Pythagorean theorem: a^2 + 10^2 = 26^2, giving a = 24 cm. Since a is half the chord, the chord is 2a = 48 cm in length.
Hence, the length of a chord of a circle is [tex]48cm[/tex].
What is the circle?
A circle is defined as a two-dimensional figure, which is round in shape where all the points on the surface of the circle are equidistant from the center point is called “[tex]P[/tex]”.
Here given that,
A circle of radius [tex]26[/tex]cm if the chord is [tex]10[/tex]cm from the center of the circle.
So,
The [tex]10[/tex]cm from the center of the circle is perpendicular of the chord and the hypotenuse is [tex]26[/tex]cm .
As we know
[tex]H^2=B^2+P^2[/tex] .......[tex](1)[/tex]
Substituting the values in the equation [tex](1)[/tex], we get
[tex](26)^2=(10)^2+B^2\\B^2=676-100\\B^2=576\\B=\sqrt{576}\\B=24cm[/tex]

There are 35 students in a class. Fifteen of them are men and 20 of them are women. The mean height of the men is 69.65 inches, and the mean height of all 35 students is 66.85 inches. What is the mean height of the women?
Answer:
64.75
Step-by-step explanation:
The total heights of men is m
so m/15 = 69.65 => m = 1044.75
The total heights of all students is s
so s/35 = 66.85 => s = 2339.75
so the total heights of women = 2339.75 - 1044.75 = 1295
The mean height of women = 1295/20 = 64.75

m/NMG = 46°, m/NML = 11x + 11, and m/GML = 8x-5. Find x.
we get that, the value of x for the given angles in the diagram is 10°.
We can see that:
∠ NMG + ∠ GML = ∠ NML
Substituting the values of the angles in the equation, we get that:
46 ° + 8 x - 5° = 11 x + 11 °
Combining the like terms:
8 x + 41° = 11 x + 11°
Taking variables on one side:
11 x - 8 x = 41° - 11°
Combining the like terms again:
3 x = 30°
Divide both sides by 3:
x = 30° / 3
x = 10°

Alfonso borrowed $2500 total from two different banks. One bank charged 4% simple interest, the other charged 3.5% simple interest. After one year, the amount of interest that Alfonso owed was $91.25. How much money did Alfonso borrow from each bank.
Alfonso borrowed $750 from the bank with 4% simple interest and borrowed $1,750 from the bank with 3.5% simple interest.
How do we calculate the amount borrowed?
Let:
x = amount borrowed from the bank that charged 4% simple interest
y = amount borrowed from the bank that charged 3.5% simple interest
Therefore, we have:
x + y = 2,500 ............................... (1)
0.04x + 0.035y = 91.25 ............................. (2)
From equation (1), we have:
x = 2,500 - y ....................... (3)
Substituting equation (3) into (2) and solving for y, we have:
0.04(2,500 - y) + 0.035y = 91.25
100 - 0.04y + 0.035y = 91.25
100 - 0.005y = 91.25
-0.005y = 91.25 - 100
-0.005y = -8.75
y = -8.75 / -0.005
y = $1,750
Substituting for y in equation (3), we have;
x = 2,500 - 1,750
x = $750
