Can't see the figure, but the basic way to solve this problem is to use the formula for volume of a pyramid which is (length * width * height )/3. Slant height is just the square root of ((length/2)2 + height2) recognizing that there is a right triangle there. Since slant height increased by 4 cm when its height increased by 2cm, you know that the length/2 term had to increase by the square root of 12 (22+root(12)2) = 42=16. From there you can figure out the rest pretty readily.
3/5 of fifteen is 9 because that's the same as saying (3/5)*15 = (45/5) = 9. Since 3/5 animals are dogs, 2/5 aren't, and 15 - 9 leaves 6 animals that aren't dogs.

Answer:
Correct choice is C
Step-by-step explanation:
The first term of arithmetic cequence is -15, the second term is -7, the third term is 1 and i.e.
The difference between two consecutive terms of the arithmetic sequence is the difference of the arithmetic sequence. Thus, the difference of the arithmetic sequence is
Hence,
- fourth term is
- fifth term is
- sixth term is
- seventh term is
Next four terms are 9, 17, 25, 33.
Answer:
139.79 yd²
Step-by-step explanation:
area of rectangle = l·w
A = 12·9 = 108
area of semi-circle = 1/2πr²
A = 1/2·(3.14)·(9/2)²
A = 31.79
area of composite shape = 108 + 31.79
A = 139.79
