Use the distance formula to determine whether ABCD below is a parallelogram. A(-3,2) B(-3,3) C (5,-3) D (-1.-5)
Answer:
ABCD is not a parallelogram
Step-by-step explanation:
Use the distance formula to determine whether ABCD below is a parallelogram. A(-3,2) B(-3,3) C (5,-3) D (-1.-5)
We have to find the length of the sides of the parallelogram using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For side AB
A(-3,2) B(-3,3)
= √(-3 -(-3))² + (3 -2)²
= √0² + 1²
= √1
= 1 unit
For side BC
B(-3,3) C (5,-3)
= √(5 -(-3))² + (-3 -3)²
= √8² + -6²
= √64 + 36
= √100
= 10 units
For side CD
C (5,-3) D (-1.-5)
= √(-1 - 5)² + (-5 - (-3))²
= √-6² + -2²
= √36 + 4
= √40 units
For sides AD
A(-3,2) D (-1.-5)
= √(-1 - (-3))² + (-5 -2)²
= √(2² + -7²)
= √(4 + 49)
= √53 units
A parallelogram is a quadrilateral with it's opposite sides equal
From the above calculation
Side AB ≠ CD
BC ≠ AD
Therefore, ABCD is not a parallelogram

- A store is located at P(50, -30). How long will it take a truck driving at
50 miles per hour to drive from warehouse N to this store?
Answer:
0.8 hour
Step-by-step explanation:
Given data
Coordinate
P(50, -30)
Say Wharehouse N has a coordinate of N(0,0)
We can find the distance between two coordinate by
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((50-0)²+(-30-0)²)
d=√50²+(-30)²)
d=√2500-900
d=√1600
d= 40 miles
We know that
Speed= distance/time
50= 40/t
t= 40/50
t= 0.8 hour
The mean of 12 numbers is 20 and the mean of another 8 numbers is 25 find the mean of the 20 numbers
Answer:
22
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Given the mean of 12 numbers is 20 , then
[tex]\frac{sum}{12}[/tex] = 20 ( multiply both sides by 12 )
sum = 240
Given the mean of 8 numbers is 25 , then
[tex]\frac{sum}{8}[/tex] = 25 ( multiply both sides by 8 )
sum = 200
Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is
mean = [tex]\frac{440}{20}[/tex] = 22
What are the measures of the other three angles formed by the intersection?
Answer:
1 = 130
2 = 50
3 = 130
Step-by-step explanation:
Since we already know that one angle is 50 degrees, this also tells us that angle two is congruent to it because it is opposite to it. Now the two other adjacent angles, basically just do 180-50 to get 130.

Which values could he use for a, b, and c?
A = 1, B = 8, C = -6
A = 1, B = -8, C = 6
A= -1, B = -8, C = -6
A = 1, B = 8, C= 6
Answer: The CORRECT answer is
a=1, b=8, c=6
Step-by-step explanation:
Took the quiz
The values that can be use for a, b and c in the equation 2x² + 7x − 5 = 0 are a = 1, b = 8, c = 6
Quadratic equation formula
The quadratic equation formula is represented as follows:
ax² + bx + c
where
a, b and c are unknown numbers. a is not 0x = unknownTherefore, lets model the quadratic equation x² + 8x + 6 = 0 to ax² + bx + c
Hence,
a = 1
b = 8
c = 6

Quadrilateral WILDWILDW, I, L, D is inscribed in circle OOO. \overline{WI} WI start overline, W, I, end overline is a diameter of circle OOO. What is the measure of \angle D∠Dangle, D?
Answer:
135degrees
Step-by-step explanation:
Find the diagram attached.
Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.
According to the diagram shown:
<D+<I = 180
<D+45 = 180
Subtract 45 from both sides
<D+45-45 = 180-45
<D = 180-45
<D= 135°
Hence the measure of <D is 135degrees
Answer: 135

Frank designed a net for a storage shed that he is going to construct out of metal. The design consists of a square base and four square sides, plus four triangular parts that make up the roof.
He had 250 square feet of metal to use to build the shed. (What is the surface area of the storage Shed that Frank Designed?) (Does Frank have enough metal to construct his design yes or no?)
Answer:
Yes, Frank does have enough, he has 250 metal and only has 228 surface area.
Step-by-step explanation:
You take all the triangles (4) and multipy 4 x 6 (24) then divide that by 2 (12) so now you know all the triangles are equal to 12. Then the squares, you multiply 6 x 6 (36) now you know all the squres are equal to 36 and then you add 12 + 12+12+12+36+36+36+36+36 and then you get 228.
students at franklin middle school were serveyed to find where they spent there summer vacation .the graph below represents the data from 80 students.
how many more students surveyed spent their summer vacation in californa than number of students who spent their summer vacation in colorado?
Answer:
B. 4 people
Step-by-step explanation:
In total, there are 80 students, so the number of people who spent their vacation in california is 25% of 80, which is 20 people.
For the number of people who went to Colorado, it is 20% of 80, which is 16.
20-16 = 4 people

in a class room 1/6 of students are wearing blue shirts 2/3 are wearing white shirts there are 12 students how many are wearing shirts other than blue shirts?
Answer:
4 students
Step-by-step explanation:
what we know: 12 students, 2/3 are wearing blue, 1/6 are wearing red
first you have to make the fractions have the same denominator(2/3=4/6)
theres also 1/6 that are not wearing blue or red (1/6+4/6=5/6, 6/6-5/6=1/6)
so that makes it 2/6 of the students not wearing blue(1/6+1/6=2/6)
simplify(2/6=1/3)
1/3 of 12 is 4 (12÷3=4)
the equations are in parentheses and bolded, italicized, underlined.
hope this helps :)
Find the area of the figure. Round to the nearest tenth
Answer:
Find the area of each triangle and then add it up. As you are aware, to find the area of a triangle the equation is B times Height divided by 2. And to make it easier do the top left triangle and the top right triangle, add them together and then divide that by 2.
Step-by-step explanation:
3 time 5 equals 15 divided by 2 equals 7.5
5 times 8 equals 40 divided by 2 equals 20
7.5 plus 20 equals 27.5
27.5 times 2 equals 55
therefor your answer should be 55m
how do I calculate the perimeter of a base from a rectangular prism?
Answer:
To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results
