What are all the possible rational solutions for x^4-3x^2+2x5=0
Answer: x = 1
x =(-3-√-15)/4=(-3-i√ 15 )/4= -0.7500-0.9682i
x =(-3+√-15)/4=(-3+i√ 15 )/4= -0.7500+0.9682i
x2 = 0

ind the measure of angle ABC.
B
8x
6x
6x
A
C.
Ok my bad last question anyways ❤️URGENT 25 EACH❤️
Answer:
angle ABC=72 degrees
Step-by-step explanation:
8x+6x+6x=180 degrees (all triangles contain 180 degrees)
20x=180
x=9
angle ABC=8x or (8)(9)=72 degrees
Answer:
72°
Step-by-step explanation:
Angle A = 6x
Angle B = 8x
Angle C = 6x
The sum of all interior angles in a triangle is 180°, which means angles A, B and C add up to 180:
A + B + C = 180
substitute in the values for A B and C:
6x + 8x + 6x = 180
Simplify by combining like terms:
6x + 6x + 8x = 180
20x = 180
solve for x:
20x/20 = 180/20
x = 9
Since we know x = 9 and angle B = 8x, u can substitute in the value of x to find the value of angle B:
B = 8x
B = 8(9)
B = 72°

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.

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$.

Triangles ABC and CDE are mathmatecilly similar. work out the length of DE. WORK OUT THE LENGHT OF AB
Answer:
[tex]DE = 15[/tex]
[tex]AB = 6[/tex]
Step-by-step explanation:
Given
See attachment for triangles
Required
Determine the lengths of DE and AB
To solve for DE, we make use of the following equivalent ratio
[tex]AC : BC =CE:DE[/tex]
Substitute values
[tex]8:5 = 24:DE[/tex]
Express as fraction
[tex]\frac{8}{5} = \frac{24}{DE}[/tex]
Cross Multiply
[tex]DE * 8 = 24 *5[/tex]
[tex]DE * 8 = 120[/tex]
[tex]DE = 120/8[/tex]
[tex]DE = 15[/tex]
To solve for AB, we make use of the following equivalent ratio
[tex]AB : BC =CD:DE[/tex]
Substitute values
[tex]AB : 5 = 18 : 15[/tex]
Express as fraction
[tex]\frac{AB}{5} = \frac{18}{15}[/tex]
Multiply by 5
[tex]5 * \frac{AB}{5} = \frac{18}{15}*5[/tex]
[tex]AB= \frac{18}{15}*5[/tex]
[tex]AB= \frac{18}{3}[/tex]
[tex]AB = 6[/tex]

A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi
Answer:
15 inches.
Step-by-step explanation:
V = 1/3 pi r^2 h
7065 = 1/3 * 3.14 * 30 * r^2
r^2 = 7065 / (1/3 * 3.14 * 30)
r^2 = 7065 / 31.4 = 225
r = sqrt 225 = 15.
