Answer:
A
Step-by-step explanation:
Rules:
odd x odd = odd
even x even = even
even x odd = even
even + even = even
odd + odd = even
odd + even = odd
We can determine whether 2a + 3b is odd if we have both statements because we know that a is odd and 2 is even, which means their product will be even. 3 is odd and b is odd, so their product will be odd. The sum of the even and odd will be odd.
If we have just the second statement we can determine the answer because anything multiplied by 2 is even.
So whether or not we know if a is odd, we know that 2a is even because 2 doubles everything which means it's divisible by 2 which means it's even.
However, statement 1 alone is not enough because if a is odd, then 2a is even. However, 3b can be even or odd depending on b. If b is odd, then 3b is odd. if b is even, 3b is even.
Therefore, if you have statement 2 you can answer the question but if you only have statement 1 then you also need statement 2

Answer:
256π
Step-by-step explanation:
Given that:
The height of the cylinder: 12 cm
The radius of the sphere : 10
Let r is the radius of the cylinder, use Pytagon
10² = r² + 6²
<=> r² = 10² - 6² = 64
<=> r = 8
Hence, the lateral area of the cylinder
L= 2πrh
= 2π8*16
= 256π
Answer:
This will give 5 Students each in 12 different equally sized groups
This also shows that students can grouped in equal groups of 12 in 5 places
Step-by-step explanation:
From the question we are told that
60 children in equal sized groups
Generally interpreting 
can be mathematically represented as
a)
This will give 5 Students each in 12 different equally sized groups
b)
This also shows that students can grouped in equal groups of 12 in 5 places
