19. 10 divided by 3 = 5 pounds
20. 5.5 divided by .5 = 11
21. no because 1.25 x 2.5 = 3.12 and she only has $3
22. the restaurant because the restaurant wants to buy 30lb and its $1.25 so 30 x 1.25 = 37.5 and the hotel buys 12 lb for $3 so that is 12 x 3= 36
Answer:
A
Step-by-step explanation:
Step-by-step explanation:
The hypotenuse of a right-angled triangle = 25 cm
One side is twice as long as the other.
Let the other side is x.
First side = 2x
Using Pythagoras theorem to find the lengths of the shorter sides.

So, the other side = 11.18 cm
First side = 2(11.18) = 22.36 cm
So, the lengths of the shorter sides are 11.18 cm and 22.36 cm.
Volume of a cube is side^3
therefor
v=27
27=side^3
what^3=27?
factor 27
27=3 times 3 times 3=3^3
27=side^3
3^3=side^3
cube roo bth sides
3=side
3 cm is on side
area=side^2
area=3^2
area=9 cm^2
the 2nd answer makes the most since
