Wayne's deli sells whole sandwiches and half sandwiches. The half sandwiches are in the shape of a triangle because they are cut

Katarina [22]

Answer:

No, those are not the correct measurements.

Step-by-step explanation:

Assuming that 9 will equal the hypotenuse we will use the Pythagorean theorem.

$a^2+b^2=c^2$

a = 5

b = 3

$5^2 + 3^2= 25 + 9 = 34$

Well $9^2= 81$

So...that doesn't quite work out.

Let's change our equation to double check.

$c^2/a^2= b^2$

$9^2/5^2 = b^2\\\\81/25 = 3.25$

Once again, that doesn't work out.

So the final answer is, no. Those are not the correct measurements.

Simplify.

Dominik [7]

Simplify: [{y^(2/7)}/{y^(1/2)}]

Since, [{a^(p/q)}/{a^(r/s)}] = a^{(p/q)-(r/s)}

Where,

a = p
p/q = 2/7 and
r/s = 1/2

so,

= y^{(2/7)-(1/2)}

Take the LCM of denominator i.e.,2 & 7 is 14.

= y^{(2*2 - 1*7)/14}

= y^{(4-7)/14}

= y^(-3/14) Ans.
