Use long division to find the quotient of 990 and 45.

22

Step-by-step explanation:

because if you divide 45 first it will be wrong so you must always first will the biggest number in your problem

22

Step-by-step explanation:

990/45

45 goes 2 times into 99 with 9 left over. Bring down the 0 and you have 90. 45 goes into 90 2 times evenly. So 22 is the answer,

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

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)
