The answer is the fourth option. Put the compass point on A and the pencil point on the segment, closer to point B than to point A, and draw a circle centered at point A. Without changing the compass opening, draw a circle centered at point B. The diagonals of a square bisect each other in mutually perpendicular. Let AB be the diagonal, when we draw a perpendicular to the diagonal AB the other two points of the square are in this perpendicular.And are in opposite sides.So we draw the two circles with same radius less than AB and greater than half of AB.
Answer:
Step-by-step explanation:
Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.
The answer should be without negative exponents.
Answer:
20.28 cm²
Step-by-step explanation:
The rectangle on the bottom is 7 cm by 2 cm.
The semicircle has a diameter of 7 cm - 1 cm - 2 cm = 4 cm
diameter = 4 cm
radius = diameter/2 = 2 cm
total area = area of semicircle + area of rectangle
total area = (1/2)πr² + LW
total area = (1/2)(3.14)(2 cm)(2 cm) + 7 cm × 2 cm
total area = 20.28 cm²
Since we know what time Dennis' sister finished babysitting, we can calculate how much money she's made since 9p.m. Between 9 and 11 is 2 hours, so we know she made $16 ($8 per hour x 2 hours).
That means she made $22 before 9p.m. ($32 total - $16 made past 9p.m.)
So, you just need to figure out how many hours $22 is worth and subtract that number of hours from 9p.m. That will get you to the starting point of babysitting.
$22 / $5.50 = 4 so we know that $22 is 4 hours' worth of babysitting.
9p.m. - 4 hours is 5p.m., so we know that Dennis' sister started babysitting at 5p.m.
