Answer:
The correct option is C. weight of sugar
So we can only measure Weight of Sugar.
Step-by-step explanation:
Balance Scale:
- It is a device for weighing.
- It has a balanced beam and two pans.
- When the pans contain exactly the same mass, the beam is in balance condition.
- You can place an object in one pan and standard weights in the other to find what the object weighs.
So we can only measure Weight of Sugar.
Answer:
C. 82
Step-by-step explanation:
A- 70x.33==23.1 (not 27 1/2)
B- 79x.33=26.07 (not 27 1 /2)
C- 82x.33= 27.333 (closest to 27 1/2)
D- 159x.33=52.47 (not 27 1/2)
**changed 1/3 into a decimal (.33)**
Hope it helps!
So I think it’s 6.5x5.6=34.6 which is the surface area for one triangle.
However there is 4 triangles so multiply by four.
34.6 x 4= 145.6m2
Answer:
80/121
Step-by-step explanation:
For simplicity,
Probabilities of getting a red, a blue or a green in a single spin are, respectively, 4/11, 4/11 & 3/11.
Therefore, probabilities of getting 2 reds, 2 blues or 2 greens in 2 spins are, 16/121, 16/121 & 9/121 respectively.
Then, total probability of getting same colour both times would be 16/121 + 16/121 + 9/121 = 41/121.
Any other option would result in 2 different colours. Thus, the probability of getting two different colours in 2 spins = 1 - 41/121 = 80/121.
