Answer:

The answer is "about 8."

Step-by-step explanation:

Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally. While it is hard to mentally calculate 55.59 divided by 7.8, it is easier to mentally calculate 56 divided by 7, because they are compatible numbers, and they are close to the numbers given in the problem (55.59 and 7.8). 56 divided by 7 leaves us with a quotient of 8, which is a good estimate for the quotient of 55.59 and 7.8.

Her gross weekly pay would be $1375.

25 * 40 = $1000

time and a half means she would make $37.50 for the 10 hours overtime she works. 10 * 37.5 = 375

375 + 1000 = $1375

Given the circle with the equation (x - 3)2 + y2 = 49, determine the location of each point with respect to the graph of the cir
Bas_tet [7]
To find out if a point is inside, on, or outside a circle, we need to substitute the ordered pair into the equation of the circle:
(x-xc)^2+(y-yc)^2=r^2
where (xc,yc) is the centre of the circle, and r=radius of the circle.

If the left-hand side [(x-xc)^2+(y-yc)^2] is less than r^2, then point (x,y) is INSIDE the circle.  If the left-hand side is equal to r^2, the point is ON the circle.
Finally, if the left-hand side is greater than r^2, the point is OUTSIDE the circle.

For the given problem, we have xc=3, yc=0, or centre at (3,0), r=sqrt(49)=7
(x-xc)^2+(y-yc)^2=r^2 => (x-3)^2+y^2=7^2

A. (-1,1), 
(x-3)^2+y^2=7^2 => (-1-3)^2+1^2=16+1=17 <49  [inside circle]

B. (10,0)
(x-3)^2+y^2=7^2 => (10-3)^2+0^2=49+0=49  [on circle]

C. (4,-8)
(x-3)^2+y^2=7^2 => (4-3)^2+(-8)^2=1+64=65 > 49  [outside circle]
