The volume of a rectangular prism is (length) x (width) x (height).
The volume of the big one is (2.25) x (1.5) x (1.5) = <em>5.0625 cubic inches</em>.
The volume of the little one is (0.25)x(0.25)x(0.25)= 0.015625 cubic inch
The number of little ones needed to fill the big one is
(Volume of the big one) divided by (volume of the little one) .
5.0625 / 0.015625 = <em>324 tiny cubies</em>
=================================================
Doing it with fractions instead of decimals:
The volume of a rectangular prism is (length) x (width) x (height).
Dimensions of the big one are:
2-1/4 = 9/4
1-1/2 = 3/2
1-1/2 = 3/2
Volume = (9/4) x (3/2) x (3/2) =
(9 x 3 x 3) / (4 x 2 x 2) =
81 / 16 cubic inches.
As a mixed number: 81/16 = <em>5-1/16 cubic inches</em>
Volume of the tiny cubie = (1/4) x (1/4) x (1/4) = 1/64 cubic inch.
The number of little ones needed to fill the big one is
(Volume of the big one) divided by (volume of the little one) .
(81/16) divided by (1/64) =
(81/16) times (64/1) =
5,184/16 = <em>324 tiny cubies</em>.
A. 540 is 60% of 900 so 900 people were surveyed.
60/100 • x= 540
Multiply both sides by 100
Then divide both sides by 60
B. If you subtract 900-540 your answer will be 360. 360 people preferred running.
Answer:
A or c!
Step-by-step explanation:
Symmetry means that you should be able to draw a straight line and have both sides of the line be a reflection of the other (reflection like in a mirror or like if you put a miror at the middle of your face and someone looked in it they would see the other side)
so the answer is yes since it can be divided
Answer: SAS
Step-by-step explanation:
Here ABC is a triangle, In which angle BAC is bisected by line AR where, 
.
Thus in triangles ABR and ACR,
AB= AC ( given)
Therefore 
( by the property of angle bisector)
And, 
(reflexive)
Thus by SAS postulate,
△ABR ≅ △ACR.
Therefore, Option D is correct.
