Which square number below 100 also prime numbers?

1 answer:

4 0

There's no this kind of number because when a number is a square number, it equals its square root multiplies itself, which contradicts with the definition of prime number (A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself). There's only 1=1×1, but since 1 isn't included in prime number, there's no answer to your question.

How do i find the proportionality of r

Paha777 [63]

Since the graph is a linear function, we're going to use the slope formula solve this:

Note I am replacing m with k
$k= \frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }$

Inserting 2 points from the graph, let's use (1,8) and (2,16).

$\frac{16-8}{2-1}

$

k=8

20 is how much less than 30? What percent less?

LenKa [72]

Answer:

33.3333% decrease

Step-by-step explanation:

Percent change formula: $\frac{(x-y)}{|y|} *100$ , where x is the new value and y is the starting value.

Plug in values and solve:

$\frac{20-30}{30} *100\\\frac{-10}{30} *100\\-0.3333*100\\$

-33.3333% change, or a 33.3333% decrease.
