Javier earns $7.50 per hour and works 20 hours per week. He wants to know how many weeks, w, he will need to work to save
$1,200.00 for school. Using the equation below, how many weeks will he need to work to save up $1,200.00?

8 Weeks

Step-by-step explanation:

Earning per hour = $7.50

and Javier works 20 hours per week

Therefore, in one week, Javier will earn $7.50 X 20 = $150

To save $1,200.00 for school, Javier will need to work;

1200.00 / amount earned per week

This will give;

1200.00 / 150

= 8 weeks

70,000 + 6,000 + 800 + 30

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
