She can fill 5/12 of the pyramid.

The volume of a pyramid is given by the formula 
V = 1/3lwh.  Using our information, we have:

V = 1/3(40)(30)(60) = 24000 cm³

She has 10,000 cm³ of sand; 10000/24000 = 5/12.

Inessa [10]

Answer:

$29.50

Step-by-step explanation:

First we need to find the tip

tip = pre tax bill * 10 %

tip = 25 * .10

tip =2.5

Next we need to find the tax

tax = pre tax bill * 8%

tax = 25 * .08

tax =2

Final bill = pre tax bill + tax + tip

Final bill = 25 + 2 + 2.5

              =29.50

Nataly_w [17]

Hey there! Welcome to Brainly!

Let's see how many marbles we have in total.

12+11+17+5=45

We want to find the probability of selecting a marble that is not blue. Let's see how many marbles aren't blue.

12+11+5=28

We have this probability out of 48.

28/48

We simplify, giving us 7/12 or about 58.33%.

I hope this helps!
