answer:
6
step-by-step explanation:
- for this you would find the volume and then divide by 1/2
v = l x w x h
v = (1)(2)(3/2)
v = 3
3 ÷ 1/2 = 6
- therefore, it will take 6 half cubes to fill up the container
Answer:
3/4=63/84
66.66%=56/84
5/7=60/84
⇒66.66%; 5/7; 3/4
Step-by-step explanation:
We need to build a system of equations:
a + b + c = 127......(1)
b - c = 13..............(2)
a - b - c = 41..........(3)
adding equations (1) and (3):-
2a = 168
a = 84
Substituting for in equation (1)-
84 + b + c = 127
b + c = 43...........(4)
Adding equations (2) and (4):-
2b = 56
b = 28
Finally from equation (2)
c = 28-13 = 15
Answer is Country a had 84 points , b had 28 points and c had 15 points.
Question Correction
Evelyn packed this box with 1 inch cubes. Which expression does not show how Evelyn can find the volume of the box?
- (A)6+6+6+6+6+6
- (B) 2 X 3 X 6
- (C) 2 + 3 + 6
- (D) 6 X 6
Answer:
(C) 2 + 3 + 6
Step-By-Step Explanation
In the diagram,
- Height = 6 Units
- Length =2 Units
- Width =3 Units
Volume = Height X Length X Width
= 6 X 2 X 3
=36 cubic units
Consider the options:
(A)6+6+6+6+6+6 =36 cubic units
(B) 2 X 3 X 6 =36 cubic units
(C) 2 + 3 + 6 = 11 cubic units
(D) 6 X 6 =36 cubic units
Out of the option, that which is not equivalent to 36 cubic units is:
(C) 2+3+6
Therefore, it does not show how Evelyn can find the volume of the box.
The LCM is 280.
