Answer:
None of the above
Step-by-step explanation:
15/45=1/3
The area of a pyramid is the sum of area of the base and the area of slant triangles.
The area of the base is 1.5 × 1.5 = 2.25 cm²
The slant height of each triangle, s is 3 cm
The area of the triangles = 1/2 × 1.5 × 3 × 4
= 9 cm²
Therefore, the area of the pyramid
=9 +2.25
= 11.25 cm²
1. 6
2. -2
3. -7
(I am a bit confused on what you are asking for the "3(-4)" one, so I decided to skip that one.)
4. 4

6. -6
Answer:
The answer is 14.46%
Step-by-step explanation:
Given is : A culture containing 20 bacteria multiplies to 117,360 in one minute.
Let A0 be initial bacteria count = 20
Let A be final bacteria count = 117360
Time = 60 seconds
R = rate
Formula to be used = 
Taking log function (ln) on both sides.
Hence, r = 0.1446 and in percentage it is 14.46%
Answer:
25 and -31
Step-by-step explanation:
Notice that if all the negatives were positive, you would have the arithmetic sequence 1, 7, 13, 19, on and on, adding 6 every time. So basically we have a geometric and arithmetic sequence combined, with the geometric sequence making it positive, and negative, and the arithmetic sequence adding 6 every time. This means the answer(s) are 25 and -31.
