Answer:
11=11*1
Step-by-step explanation:
Eleven is a prime number, you can see that by proving with other minor prime numbers. like 2,3, 5 and 7
Neighter of those divide exactly 11, except 1
Answer:
a₄ = 320
Step-by-step explanation:
To obtain a term in a geometric sequence , multiply the previous term by the common ratio r
r = = = 4 , then
a₄ = 4 × a₃ = 4 × 80 = 320
Answer:
138π m²
Step-by-step explanation:
The following data were obtained from the question:
Diameter (d) = 6 m
Height (h) = 20 m
Surface Area (SA) =?
Next, we shall determine the radius. This can be obtained as follow:
Diameter (d) = 6 m
Radius (r) =?
r = d/2
r = 6/2
r = 3 m
Finally, we shall determine the surface area of the cylinder. This can be obtained as follow:
Radius (r) = 3 m
Height (h) = 20 m
Surface Area (SA) =?
SA = 2πrh + 2πr²
SA = 2πr (h + r)
SA = 2 × π × 3 (20 + 3)
SA = 2 × π × 3 × 23
SA = 138π m²
Thus, the surface area is 138π m².
Answer:
A
Step-by-step explanation:
given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the given condition y = 2 when x = 10
k = = =
y = x ← equation of variation
when x = 40, then
y = × 40 = 8 → A
The correct option is Quantity a: the number of prime numbers between 0 and 100, inclusive is greater.

What is a prime number?</h3>
A prime number is a natural number greater than 1 that is not the sum of two lesser natural numbers (or a prime). Any natural number greater than one that is not prime is referred to as a composite number. For instance, the product 1 5 and 5 1 are the only two ways to write the number 5, making it a prime. The fact that it is the sum of two smaller integers (2 x 2), 4, however, makes it composite. Primes play a significant role in number theory because of the fundamental theorem of arithmetic, it states that any natural number greater than one is either a prime number itself or may be factored as a unique prime product up to the order of the primes. the prime number (or a prime).
The number of primes reduces almost exponentially as we move up the number line. The prime numbers between 0 and 100 are therefore far more numerous than those between 101 and 200. It is crucial to understand this general number theory point, but it may also be rapidly illustrated by attempting to find some primes in these two groups.
