The answer is C, number of snails to the total number of animals
Answer:
33.3%
Step-by-step explanation:
It was a sale for 33.3% off.
80=66.6% of 120
the last third, which is 40, equals 33.3% of 120
40 is 1/3 of 120
1/3=33.3%
The answer is 102 because you subtract 180-78.
4. B
5. B
6. D
Step-by-step explanation:
4. The radius is 3 units (3 boxes). So you do pi*r^2 = 3.14*9
5. You want the area of the box minus the area of the two circles.
Height of the box is 8 (bottom of circle to the top is two times the radius). Width of the box is 16 (left end of the left circle to the right end of the right circle) so 4 times the radius of the circles. Area of box is 128
Area of each circle is 3.14*(16). So you do 128 - 2*3.14*16.
6. Just plug in the radius 9 to the area of a circle formula: pi*radius^2 = 81*pi
