Step-by-step explanation:
Quadrilateral ABCD has vertices A(- 3, 1), B(4, 2) B(4, 2), C(9, - 3) , and D(2, - 4) . aProve that quadrilateral ABCD is a rhombus b )Prove that ABCD is not a square .
9514 1404 393
Explanation:
The vectors representing the diagonals are ...
AC = C - A = (9, -3) -(-3, 1) = (12, -4)
BD = D - B = (2, -4) -(4, 2) = (-2, -6)
The dot-product of these vectors is the sum of the products of corresponding coordinates:
(12)(-2) +(-4)(-6) = -24 +24 = 0
When the dot-product is zero, the vectors are perpendicular. These vectors are different lengths (BD = 1/2·AC), so they are not the diagonals of a square.
__
The midpoints of the diagonals will be in the same place if the quadrilateral is a rhombus.
(A +C)/2 = (B +D)/2
We can simplify our effort a bit by multiplying by 2.
A+C = B+D
(9, -3) +(-3, 1) = (2, -4) +(4, 2)
(6, -2) = (6, -2) . . . . . . . . . . . . . . . . yes, the midpoints are the same point
__
We have shown the diagonals of the quadrilateral are different lengths and perpendicular bisectors of each other, so the quadrilateral IS A RHOMBUS, NOT A SQUARE.

solve the triangle give the measure of y
Given:
In triangle [tex]BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ[/tex].
To find:
The value of y.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
In triangle BGU,
[tex]\tan B=\dfrac{GU}{BU}[/tex]
[tex]\tan 44^\circ=\dfrac{7}{y}[/tex]
[tex]0.966=\dfrac{7}{y}[/tex]
Isolating y, we get
[tex]y=\dfrac{7}{0.966}[/tex]
[tex]y=7.2463[/tex]
[tex]y\approx 7.2[/tex]
Therefore, the correct option is A.

The scale of map is 1cm : 70km. What is the actual distance between towns that are 5cm apart on the map
Answer: 350km
Step-by-step explanation:
Since we are informed that the scale of map is 1cm : 70km. Therefore, the actual distance between towns that are 5cm apart on the map will be:
= 5 × 70km
= 350km
Therefore, the answer is 350km
Brett has 100 feet of fence with which to make a rectangular cage for his dog. The area of the cage in square feet is given by the polynomial where w is the width of the cage in feet. What is the area of the cage if the width is 8 feet?
Answer:
Area of rectangle cage = 336 feet²
Step-by-step explanation:
Given:
Wire required for fencing = 100 feet
Width of rectangular cage = 8 feet
Find:
Area of rectangle cage
Computation:
Wire required for fencing = perimeter of cage
Perimeter of rectangular cage = 100 feet
2[l + b] = 100 feet
l + 8 = 50 feet
Length of rectangular cage = 42 feet
Area of rectangle cage = Length x Width
Area of rectangle cage = 42 x 8
Area of rectangle cage = 336 feet²

Two sides of a triangle have length 10 and 17. What is the range of the length of the 3rd side
Answer:
13.7477270849 to 19.7230829233.
Step-by-step explanation:
1. Using the pythagorean theorem, a²+b²=c², we try different combinations of given lengths 10 and 17.
2. If 10 and 17 are legs and 10²+17²=√389 = 19.7230829233, then c=19.7230829233.
3. If 10 is a leg and 17 is a hypotenuse,
10²+b²=17²
100+b²=289
b²=189
b=13.7477270849
4. The case of 17 is a leg and 10 is a hypotenuse is not possible because the hypotenuse is the longest side.
5. The range of the length of the 3rd side is 13.7477270849 to 19.7230829233.

The ratio of potatoes to onions is 1:2 respectively if there are 14 onions how many photatoes are there
Answer:
7
Step-by-step explanation:
The ratio of potatoes to onions is 1:2, meaning there are twice as many onions as potatoes.
[tex]\frac{\text{potatoes}}{\text{onions}}=\frac{1}{2}=\frac{x}{14}[/tex]
The fraction on the right is equivalent to 1/2, so the numerator is half the denominator. There are 7 potatoes.
Q1.) A carton contains 25 cards numbered 1 to 25. Alecia picks a card randomly. What is the probability that Alecia will pick an odd number?
Answer:
52%
Step-by-step explanation:
Since there are 25 numbers in 1-25, you need to divide 100/25 which is 4.
There are 13 odd numbers in 1-25 so you need to multiply 13x4.
13x4=52
There is a 52% chance she will pick an odd number.
What does the 49 days until Fourth of July there are seven days in a week and how many weeks will it be Fourth of July
Answer:
It will be Fourth of July in 7 weeks.
Step-by-step explanation:
Since you know that there are seven days in a week, you can use a rule of three to find the amount of weeks in 49 days that is the number of days until Fourth of July:
7 days → 1 week
49 days → x
x=(49*1)/7
x=7
According to this, the answer is that it will be Fourth of July in 7 weeks.
A factory manufactures 9 x 10^5 packs of gum each month. They send these out to 16 different distribution centers. If each distribution center gets the same number of packs, how many are sent to each center?
Answer:
The answer would be A.
Step-by-step explanation:
You would take 9 x 10^5 = 900000 and divide that by 16 to get 56250.
After that, you move the decimal over by 4 to make it a number with only one number above zero in front of the decimal to make 5.625 (negate the 0 bc it does not mean anything after you moved the decimal over)
Since you moved it over by four places, the exponent next to the 10 will be 4, making the final answer 5.625 x 10^4
Good luck and hope this helps!!
Carolina va a repartir entre sus estudiantes una barra de chocolate, a Valeria le da 5/18, a Camila le da 1/3, a Carlos 2/9 y a Pedro 1/6. Al ordenar los estudiantes, desde el que recibió más chocolate hasta el que recibió menos, se obtiene:
Respuesta:
Camila> Valeria> Carlos> Pedro
Explicación paso a paso:
Dado que :
Valeria = 5/18
Camila = 1/3
Carlos = 2/9
Pedro = 1/6
Podríamos convertir las acciones recibidas a decimal para facilitar la comparación:
Valeria = 5/18 = 0,27777
Camila = 1/3 = 0.3333
Carlos = 2/9 = 0,2222
Pedro = 1/6 = 0.16666
Comparando los decimales:
0,3333> 0,2777> 0,2222> 0,16666
Camila> Valeria> Carlos> Pedro
