Answer:

Olivia babysat for a total of 15 hours.

Step-by-step explanation:

8.50(h) + 12 = 139.50

In order to get a direct result of the hours she

worked, we have to subtract 12 on both sides:

8.50(h) + 12 - 12 = 139.50 - 12

In order to fine the value of time she spent, we have to divide the amount of money she got on both sides:

8.50(h) = 127.5

8.50 = 8.50

h = 15

Therefore, Olivia babysat for a total of 15 hours.

How were the latin american policies of president theodore roosevelt and president wilson similar

zysi [14]

Ultimately Woodrow Wilson's preferred direction was not to get involved with the internal affairs of the USA's near neighbors in Latin America. However events unfolded that meant his governments ended up being as interventionist as those of Teddy Roosevelt, for example occupying Haiti and the Dominican Republic. These activities were not intended plans of Wilson's in the way that Roosevelt set out to police Latin America but nonetheless the impact was the same.

The equation of a circle whose center is (3,7) and whose radius is 6 is

Aleks [24]

The equation of any given circle is:
${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$
where (h, k) is the center and r is the radius.

In the problem, we are given the center, and the radius. When we plug them in:
${(x - 3)}^{2} + {(y - 7)}^{2} = 36$
we got the formula of the circle.
