What is the surface area of this square pyramid?

Karo-lina-s [1.5K]

Answer:

A;3600 yd2

Step-by-step explanation:

The surface area is found by adding the area of the sides

The area of the bottom is

A= s^2 where s is the side length since it is a square

A = s^2 = 30^2= 900

We can find the area of one of the sides and multiply by 4 since all the sides are the same

The sides are triangles so

A = 1/2 bh where b is the base b=30 and h is the height = 45

A = 1/2 (30)* 45

A = 675

We have 4 of these triangles

4*675 =2700

Add the 4 triangles and the bottom

2700+900

3600

Cameron earn's $7 per hour at her after school job. The total amount of her paycheck varies directly with the amount of time she

polet [3.4K]

Answer:

Proportionality equation: $y=7kx$

Linear equation: $y=7x$

Step-by-step explanation:

So the amount that Cameron earns = 7/hr

Hours = x

And total earned amount = y

So we can form an equation from this for the total amount:

$y=7x$

But the question asks us for a proportionality equation so:

Proportionality constant = k

So we get the equation:

$y=7*k*x$
