How many cubes with edge lengths of 1/4 in. will it take to fill the prism?

Mathematics

Ulleksa [173]2 years ago
3 0

Answer:

1560

Step-by-step explanation:

First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10

Next, 3/(1/4) = 3(4) = 12

Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13

This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.

Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8

A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64

(195/8)/(1/64) = (195/8)(64) = 1560 cubes.

What is the probability of getting an even number on the roll of a six-sided die? 1/6 1/3 1/2
givi [52]

Answer: 1/2

Step-by-step explanation:

The sample space when a six sided die is thrown once is :

{ 1,2,3,3,5,6}

The even numbers are :

{2,4,6}

Therefore :

P(even) = n(even) / total number

That is

P(even) = 3/6

P(even) = 1/2

I need a help please <br> Answer for me all the question
irina1246 [14]

Answer:

see below

Step-by-step explanation:

The sum of the interior angles is 180

<1 + <2 + <4 = 180

<1 + 31+ <4 = 180

<1 + <4 = 180-31

<1 + <4 = 149

<2 + <3 = 180 because it forms a straight line

31 + <3 = 180

<3 = 180-31

<3 = 149

Setting theses equal (since they are both equal to 149)

<1 + <4 = <3

The exterior angle is equal to the sum of the opposite interior angles

The school cafeteria served three kinds of lunches today to 225 students. The students chose the cheeseburgers three times more
r-ruslan [8.4K]

1)

Let the number of fish sandwiches sold br represented by x

Then the number of grilled cheese sold is 2X

and the number of cheeseburgers 3(2x)

x + 2x + 3(2x) = 225

and solve

2)

Let x represent the no. of pounds of peanuts

Then x + 14 represents the no of pounds of the mixture

And

(2.25)x + (3.25)(14) = (2.65)(x + 14

and solve

3) Try on your own

plz mark me as brainliest :)
