Answer:
3927 litres of oil to the nearest litre.
Step-by-step explanation:
The volume of the cylinder = π r^2 h
= π * 100^2 * 250.
When half full the volume is
1/2 * π * 100^2 * 250
= 3926991 cm^3 Dividing this by 1000:
= 3927 litres.
Answer:
c.10x90
Step-by-step explanation:
if you multiply 10 by 90 it will give you 900. i learned math a weird way. i think this only works with 10's. if you take 1 and 9 and multiply them you will get 9. then there are two zeros in total out of 10 and 90 then you add them to the 9 to get 900
Answer:
Step-by-step explanation:
The same space of this experiment is the possible outcomes of selecting two out of the three breakfast. let the sample space = B
the sample space = {(cereal and egg), (cereal and fruit), (fruit and egg), (fruit and cereal), (egg and fruit), (egg and cereal)}
b) A = {(cereal and egg), (cereal and fruit), (egg and cereal), (fruit and cereal)}
A ⊆ B =n(A) ≤ n(B) (4≤6) = {(cereal and egg), (cereal and fruit), (egg and cereal), (fruit and cereal)} ⊆{(cereal and egg), (cereal and fruit), (fruit and egg), (fruit and cereal), (egg and fruit), (egg and cereal)} where a subset means all the element of A can be found in B.
Answer:
381 cubic inches
Step-by-step explanation:
To find the volume of the cube, use the volume formula for a rectangular prism V = l*w*h and for a triangular prism V = 1/2 l*w*h.
<u>Rectangular prism</u>
Substitute l = 16, w = 7, and h = 3.
V = 16*7*3 = 336 cubic inches
<u>Triangular prism</u>
Substitute l = 5, w = 3 and h = 6.
V = 1/2*5*3*6 = 45 cubic inches
Together the volume will be 336 + 45 = 381.
