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
Answers
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$.

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
Answers
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].

Ok my bad last question anyways ❤️URGENT 25 EACH❤️
Answers
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°
hope this helps!

What is the distance from point (-5, 6) to point (-5.-2)?
Answers
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.

A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi
Answers
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.
