Find the value of x in the parallelogram
Leo wants to determine the average number of texts middle school students send in a day. Since all middle school
students are enrolled in history, he randamly surveyed 4 'students from each of Mr. Barnes's eighth-grade history
classes. Ms. Lopez and Mrs. Frank also teach eighth-grade history. What should Leo do to ensure his sample is
representative of all middle school students?
O He should take the sample as is because he randomly surveyed students in each of Mr. Barnes's classes.
He should also take a sample from Ms. Lopez's and Mrs. Frank's classes so that each student has the same
chance of being chosen.
O He should also take a sample from each of the other history classes in all of the other grades in the middle school.
O He should survey al the students in all the history classes to make sure he collects enough data.

Solve for X. 2y-4x=10
Answer:
y = 5 + 2x
Step-by-step explanation:
Simplifying
2y = 4x + 10
Reorder the terms:
2y = 10 + 4x
Solving
2y = 10 + 4x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = 5 + 2x
Simplifying
y = 5 + 2x

What is the distance from point (-5, 6) to point (-5.-2)?
Answer:
8
Step-by-step explanation:
(-5,6) (-5,-2)
Notice how the two points have the same x-coordinate. This means that they are directly on top of each other. To find their distance, all we need to do is subtract their y-coordinate values.
6-(-2)
Two negatives make a positive
6+2
8
Therefore, the distance between the two points is 8 units.
I hope this helps!

A triangle has an area of 72 cm² and a base of 10 cm². What is the height of the triangle?
Answer:
14.4
Step-by-step explanation:
Area= 72 cm^2
Base= 10 cm
height= ?
Area= base x 1/2 x height
72 = 10 x 1/2 x h
72= 5 x h
72/5 = h
h= 14.4
Given the function below, what is the value of g(4)?
g(x)=3x2−3x−9
Select one:
A. 15
B. 27
C. 38
D. 56
Answer:
g(x) = 3x^2-3x-9
g(4) =3(4)^2-3(4)-9
g(4)=3(16)-12-9
g(4)=48-12-9
g(4)=27
So B is the correct answer.

The perimeter of a right-angled triangle is 96 cm.
The lengths of its sides are in the ratio 6:8:10
Work out the area of the triangle in cm”.
B x W x = 2
Total marke: 4
Answer:
[tex]A=384\ cm^2[/tex]
Step-by-step explanation:
Let the sides of a triangle be 6x,8x and 10x.
Perimeter of the triangle, P = 96 cm
We need to find the area of the triangle.
P = sum of all sides
6x+8x+10x = 96
24x = 96
x = 4
Sides are :
6x = 6(4) = 24 cm
8x = 8(4) = 32 cm
10x = 10(4) = 40 cm
Area,
[tex]A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2[/tex]
So, the area of the triangle be [tex]384\ cm^2[/tex].

Un estudiante de álgebra ha ganado $100,000 en una lotería y desea depositarlos en cuentas de ahorros en dos instituciones financieras. Una cuenta paga 8%de interés simple pero los depósitos se aseguran sólo a $50,000. La segunda cuenta paga 6.4% de interés simple y los depósitos se aseguran hasta $100,000 determine si el dinero se puede depositar para que quede completamente asegurado y gane un interés anual de $7,500
Answer:
Si puede asegurarse, ya que la inversión en la cuenta bancaria que da un 8% anual, es menor a 100 000 y mayor que 500 000.
Step-by-step explanation:
Ci= 100 000 $
Cuenta #1 = 8% de interés simple. con depósitos de 50 000$.
La segunda para 6.4% con interés simple para depósitos de 100 000$
Determine si el dinero se puede depositar para que fenere un interés de 7500
7500 = C1(0.08)+C2(0.064)
C1+C2= 100 000
C2 = 100 000 -C1
7500 = C1(0.08)+(100 000 - C1)(0.064)
1100= 0.016 C1
C1= 68750$.
