Answer:
y = 3 + 0.40x
Step-by-step explanation:
Fixed cost of taxi fare = $3
Additional cost = $0.40
Let
y = Total cost
x = number of kilometers
The equation:
Total cost = Fixed cost of taxi fare + (Additional cost * number of kilometers)
y = 3 + 0.40x

What is the circumference of the circle whose equation is (x − 9)2 + (y − 3)2 = 64?
Answer:
C = 16pi or ≈50.24 units
Step-by-step explanation:
(x − 9)^2 + (y − 3)^2 = 64
This equation is in the form
(x-h)^2 + (y-k)^2 = r^2
The radius is 8
The circumference is given by
C = 2*pi*r
C = 2*pi*8
C = 16 pi
Using 3.14 as an approximation for pi
C = 16(3.14)
C ≈50.24

What is Heron's formula of area of triangle?
Then the semi-perimeter is, s = (a + b + c)/2 = (3 + 6 + 7)/2 = 8. We will find the area of the triangle using the Heron's formula. This formula was derived by a mathematician known as the Hero of Alexandria.

...What is the area of formula of area of triangle?The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Substitute 14 for b and 10 for h in the formula.Answer:
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Step-by-step explanation:
Heron's formula allows us to find the area of any triangle when given the length of the three sides of the triangle. Let [tex]s[/tex] represent the semi-perimeter of the triangle and let the three sides be [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex].
The semi-perimeter is equal to half the perimeter and is calculated by:
[tex]s=\frac{a+b+c}{2}[/tex]
After you've found [tex]s[/tex], multiply it by the difference between it and each of the sides of the triangle. Then take the square root of that value to find the area of the triangle. Therefore, Heron's Formula is:
[tex]\boxed{A=\sqrt{s(s-a)(s-b)(s-c)}}[/tex]

draw two intersecting line segment AB and CD intersecting O. Measure the size of each pair of vertically opposite angles. Verify each pair of vertically opposite angles are equal.
When two line segments intersects, a set of vertically opposite angles are formed. So that by comparison of angles formed in the attachment, a set of vertically opposite angles formed are: >AOC and >BOD; then >AOD and >BOC.
A pair of vertically opposite angles are formed when two lines meet at a point. And the pair of vertically opposite angles formed are said to have equal size.
From the given question, line segment AB intersecting CD at point O would produce a set of vertically opposite angles. So that each pair has equal size.
From the attached diagram, it can be observed that;
m>AOC = m>BOC = m>AOD = m>BOD = [tex]90^{o}[/tex]
But;
m>AOC ≅ m>BOD = [tex]90^{o}[/tex] (vertically opposite angle property)
also,
m>AOD ≅ m>BOC = [tex]90^{o}[/tex] (vertically opposite angle property)
Therefore it can be verified that each pair of vertically opposite angles are equal.
NB: The required diagram to the question is herewith attached to this question for more clarifications and reference.

A department store is ordering the fall line of shoes. Which of the following statistical measurements would they use to determine what sizes they should order the most? A. range B. median C. mean D. mode
Answer:
Mode
Step-by-step explanation:
If I'm not mistaken the mode is the value that appears most which in this case would mean the size that is bout the most.So he should use the mode which basically shows what size is bought the most and buy that size
The statistical measurements they would use to determine what sizes they should order the most is mode option (D) is correct.
What is the mode?It is defined as the highest frequency of data and how many times the element is repeated in the data set, known as the mode value.
We have:

it is a rectangle. 18m × 4m = 72 m²
the paving costs $35 per m², and we have 72 m², so it does not take a genius to figure out what to do next ...
right : we multiply 35 by 72
35×72 = $2520

how much volume is a liter ?
a liter fits into a cube of 10cm side length.
and 1 meter = 100 cm = 10×10cm.
so, 1 m³ = 10×10×10 = 1000 such cubes of 10cm side length = 1000 liters.
the pool is 5 m × 15 m × 1.5 m = 112.5 m³ = 112500 liters
we need 2 kg salt for every 10000 liters water, so we have how many units of 10000 liters in the pool ?
112500 / 10000 = 11.25
so, we need
11.25 × 2 = 22.5 kg salt

12 seconds = 1/5 of a minute.
so, batman runs at 3 km / min (= 60×3 km/hour = 180 km/h - not possible in real life for any human being, but let's play ...) for 12 seconds = 1/5th of a minute, and so he runs 3km/5 = 600 meters in that time.
that means he has 2km - 600m = 1400m left to run in the 2 km race.
it takes him 1400/3000th of a minute (3000 m would take him the full minute)
1400 m × minute / 3000 m = 14/30 = 7/15 minutes
1/15th minute = 60 seconds / 15 = 4 seconds.
so, 7/15th of a minute = 7×4 seconds = 28 seconds.
the bionic woman runs the full 2000 m with 5 km / minute.
it takes her 2000/5000th of a minute
2000 m × minute / 5000 = 2/5th of a minute.
1/5th of a minute is 60 seconds / 5 = 12 seconds.
so, 2/5th of a minute is 12×2 = 24 seconds.
therefore, the bionic woman wins by 4 seconds (24 seconds vs. 28 seconds).

there is enough food for 150 students for 5 days = 150×5 =750 "food units".
therefore, if there were only 100 students, the food would last 750/100 = 7.5 days.
and if the food runs out after 4 days it means there are
750/4 = 187.5 students (how much sense that makes to have half a student ...).

x = the workload to be done
Michelle's work speed is x/6 days
Danielle's work speed is x/4 days
on each day working together they achieve
1× x/6 + 1× x/4 of the total work load.
that is
2x/12 + 3x/12 = 5x/12
so, they need 5x/12 × a days to finish the whole x.
5x/12 × a = x
5/12 × a = 1
5a = 12
a = 12/5 = 2.4 days to finish the whole work when working together.

Phone calls to texts is 3 to 5, so for every 3 phone calls she makes 5 texts:
Divide total phone calls by 3:
27/3 = 9

solve for w: 7w < -56
Lets solve
[tex]\\ \sf\longmapsto 7w<-56[/tex]
Take 7 to right side[tex]\\ \sf\longmapsto w<dfrac{-56}{7}[/tex]
Simplify[tex]\\ \sf\longmapsto w<-8[/tex]
Answer:
[tex]\boxed {\boxed {\sf w < -8}}[/tex]
Step-by-step explanation:
We are given an inequality and asked to solve for the variable w.
[tex]7w < -56[/tex]
In order to solve for w, we must isolate the variable. It is being multiplied by 7. The inverse of multiplication is division, so we divide both sides of the inequality by 7.
[tex]\frac {7w}{7} < \frac {-56}{7}[/tex]
[tex]w < \frac{-56}{7}[/tex]
[tex]w < -8[/tex]
w is less than -8 or w < -8.

What are the root(s) of the quadratic equation whose related function is graphed below?
Answer:
0 and 4
Step-by-step explanation:
roots are where the graph intersects at x axis
The roots of the quadratic equation whose related function is graphed are 0 and 4, the correct option is C.
What is the quadratic equation?A quadratic equation is a second-order equation written as ax2 + bx + c = 0 where a, b, and c are coefficients of real numbers and a ≠ 0.
If b2 – 4ac > 0 roots are real and different. As the discriminant is >0 then the square root of it will not be imaginary. It has two cases.
If b2 – 4ac is a perfect square then roots are rational. As the discriminant is a perfect square, so we will have an integer as a square root of the discriminant. Hence, the roots are rational numbers.
The shape of the graph is a downward parabola on the positive x-axis therefore the roots of the graph are positive.
From the given option the roots of the equation are 0 and 4 both are positive.
Hence, the roots of the quadratic equation whose related function is graphed are 0 and 4.

Answer:1. 0.889, 2. −0.4, 3. 0.636 (i rounded the answers to the nearest thousandths)
Step-by-step explanation: the thing is when you are changing them from fraction to decimal you use long division for example
let us say the fraction is a half.
we put the numerator inside and the denominator outside.
so in this case 2 is outside and 1 is inside.
(forgive my drawing)
So after the zero we put a point if it is any number we still put a point after the first division answer.
We also put a zero next to 1 even though it is any other number a the answer on top we still put a zero if the number is over like in this case.
so 10 divide by 2 is 5 we put it on top.
Since we got an answer with no reminder our answer is 0.5.
