A quadrilateral has vertices A(3,0),B(-4,4),C(-7,0) and D(-3,-5).Find the midpoints coordinates of each sides
Answer:
See explanations below
Step-by-step explanation:
Given the quadrilateral ABCD
A(3,0),B(-4,4),C(-7,0) and D(-3,-5)
The sides of the quadrilateral are AB, BC, CD and AD
The midpoint coordinate of the line is expressed as;
X = x1+x2/2
Y = y1+y2/2
Given A(3,0),B(-4,4)
Midpoint of AB = (3-4/2, 0+4/2)
midpoint of AB = (-0.5, 2)
Given B(-4, 4),C(-7, 0)
Midpoint of BC = (-4-7/2, 4+0/2)
midpoint of BC = (-11/2, 4/2)
Midpoint of BC = (-5.5, 2)
Given C(-7, 0) D(-3,-5)
Midpoint of CD = (-7-3/2, 0-5/2)
midpoint of CD = (-10/2, -5/2)
Midpoint of CD = (-5, -2.5)
Given A(3,0),D(-3, -5)
Midpoint of AD = (3-3/2, 0-5/2)
midpoint of AD = (0/2, -5/2)
Midpoint of AD = (0, -2.5)

What is the value of X?
Answer:
12
Step-by-step explanation:
Midsections are half of the length of the base of the triangle. 12 - 2 = 10 and half of 20 would be 10.
Answer:
Its most likely 8 because the second layer is 10 and it goes -2 so 10 - 2 is 8

Mr. Jaxon tips 25% of the dinner bill before tax. The expression 0.25(102−x) models the tip amount for a total bill of $102, where x is the dollar amount of tax. Mr. Jaxon tips $23.50. How much is the tax?
Answer: 1.02
Step-by-step explanation:because it is
The tax amount for the dinner bill can be calculated with the given expression.The tax amount for the dinner bill given by Mr jaxon is $8.
Given-
Total Total amount of the bill dinner is $102.
Tips given by Mr. Jaxon [tex]t[/tex] percent is 25 percent of the dinner bill before tax.
The expression for the tip amount [tex]t[/tex] can be model as,
[tex]t=0.25(102-x)[/tex]
Here [tex]x[/tex] is the tax amount.
Put the value of the tip in the above expression we get,
[tex]23.5=0.25(102-x)[/tex]
Divide by 0.25 both side, we get,
[tex]\dfrac{23.5}{0.25} =(102-x)[/tex]
[tex]94 =(102-x)[/tex]
Rewrite the equation for the [tex]x,[/tex]
[tex]x=102-94[/tex]
[tex]x=8[/tex]
Thus, the tax amount for the dinner bill given by Mr jaxon is $8.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman B a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman C a proportional relationship? Use complete sentences to explain your reasoning.
Answer:
See below
Step-by-step explanation:
Proportional relationship formula:y = kxAs per given we have:
Salesman A
p(s) = 65s (p = $1300 maximum)This is a proportional relationship, $65 per each sale. But this is restricted to 20 sales.Answer is yes (ignoring the restriction)Salesman B
p(s) = 40s + 300This is a linear but not proportional relationshipAnswer is noSalesman C
p(s) = 900There is no relationship between sales number and weekly earning as it is a fixed salaryAnswer is noHow many times would that person's heartbeat if he/she ran a 5K

Which statement is the correct interpretation of the inequality −4 > −5?
On a number line, −4 is located to the left of 0 and −5 is located to the right of 0.
On a number line, −4 is located to the right of 0 and −5 is located to the left of 0.
On a number line, −4 is located to the right of −5.
On a number line, −4 is located to the left of −5.
Answer:
On a number line, −4 is located to the right of −5Step-by-step explanation:
We know that numbers increase from left to right on the number line.
- 4 > - 5 means:
- 4 is greater than -5 and therefore is located to the right of -5Correct choice is:
On a number line, −4 is located to the right of −5Answer:
On a number line, -4 is located to the right of 5!
Step-by-step explanation:
It is closer to the 0 therefore it is greater than 5 if you want more information...

If the mountain is 1,200 feet tall, find the length of the ski lift. *
360 ft
452 it
Ski Lint
Mountain
Answer:
The length of the sky lift is 3.387.05 ft
Step-by-step explanation:
By an online search, i found that the sky lift rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such that:
One cathetus is 1200ft, this is the opposite cathetus to the angle of 20.75°
The length of the ski lift would be the hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus = 1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse = 1200ft/sin(20.75°) = 3.387.05 ft
The length of the sky lift is 3.387.05 ft

The diagonals of kite ABCD intersect at E. If ∡EBC=30°, what is ∡BCE?
Answer:
∡BCE = 60
Step-by-step explanation:
Here, we want to find the angle marked BCE
From our diagram, the angle marked BCE is y
Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE
mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180
Thus, we have that;
y + 30 + 90 = 180
y = 180-120
y = 60

Answer:
Answer:
x= −1/2 y+7
Step-by-step explanation:
Let's solve for x.
2x+y=14
Step 1: Add -y to both sides.
2x+y+−y=14+−y
2x=−y+14
Step 2: Divide both sides by 2.
