Answer:
72 square units
Step-by-step explanation:
The figure shown has a uniform horizontal cross section, so is equivalent to a rectangle with length 12 and height 6. Its area is given by the rectangle formula:
A = LW
A = (12)(6) = 72 . . . . square units

<em>Additional comment</em>
Essentially, the semicircle removed from the left side is tacked onto the right side. The rectangle area is unchanged by that.
Answer:
To convert radians to degrees, multiply by 180π , since a full circle is 360° or 2π radians. Cancel the common factor of π . Move the leading negative in −8π3 - 8 π 3 into the numerator. Factor π π out of −8π - 8 π
Step-by-step explanation:
Answer:
116°
Step-by-step explanation:
180-64=116°
Since the lines are parallel, x is equal to 116°
Answer:
0.027 to the nearest thousandth.
Step-by-step explanation:
There are 14 marbles in the bag, so:
Prob( a blue on the first draw) = 5/14.
Prob( a blue on the 2nd draw) = 4/13.
Prob( a blue on the 3rd draw) = 3/12 = 1/4.
So the required probability is 5/14 * 4/13 * 1/4
= 20/ 728
= 0.02747.
Answer:
We want to divide 30 by it's half.
The half of 30 is 30/2 = 15
then we have: 30/15 = 2
Now we want to add the half of 18, that has ben divided by the half of the half of 12 hafter been divided by half.
The half of 12 is 12/2 = 6
the half of the half of 12 is 6/2 = 3
now, we wanto to divide the half of 18 by that number.
The half of 18 is 18/2 = 9
then we have 9/3 = 3
and we wanted to add this to the number previous found:
2 + 3 = 5
