a greenhouse has the shape of a square pyramid. the base has a side length of 30 yards. the height of the greenhouse is 18 yards
snow_lady [41]

space inside the greenhouse is 5,400 yards^3 .

<u>Step-by-step explanation:</u>

We have , a greenhouse has the shape of a square pyramid. the base has a side length of 30 yards. the height of the greenhouse is 18 yards.  We need to find how much space is inside the greenhouse . Let's find out:

We know that Volume of square Pyramid is , Volume = A(\frac{h}{3}) Where

a = Area of Base

h = height of Pyramid

According to Question , h=18 yards and , side = 30 yards , So Area of base

⇒ (side)^2

⇒ (30)^2

⇒ 900yards^2

Now , Volume is

⇒ A(\frac{h}{3})

⇒ 900(\frac{18}{3})

⇒ 900(6)

⇒ 5,400 yards^3

Therefore, space inside the greenhouse is 5,400 yards^3 .

A piece of buttered toast falls to the floor 17 times. The toast landed buttered side up 6 times. What is the probability that t
kirza4 [7]

Step-by-step explanation:

Given that,

A piece of buttered toast falls to the floor 17 times. The toast landed buttered side up 6 times.

It means that the total number of outcomes are 17

We need to find the probability that the toast lands buttered side down. Favourable oucome is 17-6 = 11

So, probability is given by :

P(E)=\dfrac{\text{favourable outcomes}}{\text{total no of outcomes}}

P(E)=\dfrac{11}{17}

So, the  probability that the toast lands buttered side down is 11/17.
