Answer:

$1680

Step-by-step explanation:

The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.

Account 1:

I = (8000)(0.065)(6)

I = $3,120

Account 2:

I = (8000)(0.03)(6)

I = $1,440

$3120 - $1440 = $1680

1. The perimeter of a piece of paper is 18 cm.
OlgaM077 [116]

Answer:

a) length = 3 and width = 6

Area of the rectangle = 3 × 6 = 18 cm²

b)  length = 7 and width = 2

Area of the rectangle = 7 × 2 = 14 cm²

c)  length = 5 and width = 4

Area of the rectangle = 5× 4 = 20 cm²

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given perimeter of the paper = 18 cm

we know that the paper has a rectangle shape

The perimeter of the rectangle = 18 cm

 2( l + w ) = 18

a)

we choose length = 3 and width = 6

The perimeter of the rectangle = 2( 3+6) = 18 cm

Area of the rectangle = 3 × 6 = 18 cm²

b)

we choose length = 7 and width = 2

The perimeter of the rectangle = 2( 7+2) = 18 cm

Area of the rectangle = 7 × 2 = 14 cm²

c)

we choose length = 5 and width = 4

The perimeter of the rectangle = 2( 5+4) = 18 cm

Area of the rectangle = 5× 4 = 20 cm²

If the graph of the function g defined by g(x)=-2x^2+9. Is translated vertically downward by 8 units, it becomes the graph of a
tester [92]
G ( x ) = - 2 x² + 9
If this function is translated vertically downward by 8 units it becomes:
f ( x ) = g ( x ) - 8
f ( x ) = - 2 x² + 9 - 8
Answer:
f ( x ) = - 2 x² + 1

A un paciente se le toma la temperatura a las 7 am, 9 am, 2 pm y a las 4 pm. La primera segunda y cuarta lecturas son de 66 grad
Gnesinka [82]

Answer:

94

Step-by-step explanation:

(Lo siento, español no es mi primero lingua, pero intentaré mi mejor :) )

La ecuación is (66 + 90 + x + 94)/4 = 86

Multiple los dos de los lado por 4.

66 + 90 + x + 94 = 344

Hace 66 + 90 + 94, y ponelos a la otro lado con sustracción.

X = 94

94 es la tercera lecture.
