Answer:
$250
Step-by-step explanation:
The numbers in the table indicate a proportional relationship between earnings and hours worked. Among other things, that means you can find the earnings for 20 hours by using any table values that sum to 20 hours.
For example, 9 hours + 11 hours = 20 hours, so the earnings would be ...
$112.50 +137.50 = $250.00 . . . for 20 hours
You could also use 4×5 hours = 20 hours, so ...
4×$62.50 = $250 . . . for 20 hours
__
Or, you can figure ...
$37.50/(3 h) = $12.50/h
so the pay for 20 hours is ...
(20 h)×($12.50/h) = $250.00
6.5 is equal to 65/10 the reciprocal of that is 10/65=2/13
Answer: 60 miles
Step-by-step explanation:
Given
It takes ferry 2 hours to travel to town A and only
to travel back to town B.
Speed of current is 
Suppose the speed of the ferry is
mph
Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.

Distance between the towns is 
Usando conceptos de funciones cuadráticas, se encuentra que:
- El máximo ingreso será alcanzado en 6 años.
- El máximo ingreso será de 800 miles de soles.
La función que estimate el tiempo es dada por:

Que es una función cuadrática con coeficientes
.
El año en qué se alcanzará el máximo ingreso es el <u>valor de t de el vertice</u>, o sea:

El máximo ingreso será alcanzado en 6 años.
El valor del máximo ingreso es el valor de <u>I de el vertice</u>, o sea:

Entonces:

El máximo ingreso será de 800 miles de soles.
