3.375 because 9 is 3/4th of the 12 so you would divide 4.5 by 4 and multiply by 3 and it gives you 3.375

A local hamburger shop sold a combined total of 380 hamburgers and cheeseburgers on Friday. There were 70 fewer cheeseburgers so

NISA [10]

c= cheesebuger

h= hamburger

h=c+70

c+h=380

c+c+70=380

2c+70=380

2c=310

c=150

h =c+70

h=230

Consider the incomplete paragraph proof. given: isosceles right triangle xyz (45°–45°–90° triangle) prove: in a 45°–45°–90° tria

mash [69]

1. We have to prove that in a 45°–45°–90° isosceled triangle, the hypotenuse is times the length of each leg.

2. Since, triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, which states $a^2+b^2=c^2$

But, in isosceles triangle it becomes

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

3. By combining like terms, we get

$2a^2=c^2$

4. Now, we will determine the principal square root of both sides of the equation.

$\sqrt2 a = c$

5. Dividing both sides of the equation by '2', we get

$\frac{a}{\sqrt 2} = \frac{c}{2}$

$a = \frac{c}{\sqrt 2}$

So, $c = \sqrt{2}a$

6. So the hypothenuse c is $\sqrt 2$ times the length of each leg 'a'.

Given the points (2, 2) and (-1, -7) find the slope.

Softa [21]

Slope is change in y over the change in x.

Slope = (-7 - 2) / (-1 -2)

Slope = -9/-3

Slope = 3
