Answer:
B. 8
Step-by-step explanation:
Triangle's weight is equal to the sphere's weight.
Total of 16 blocks. Since the triangle's weight is equal to the sphere's, the weight will be half of the blocks.
Divide 2 from 16.
16/2=8
The triangle's weight is equal to 8 blocks.
Hope this helps!
If not, I am sorry.
Answer:
10
Step-by-step explanation:
Solution 1: At first, you might think that because there are 5 ways to choose the first store and 4 ways to choose the second store, the answer is 5 * 4 = 20 but this is over-counting by a factor of 2. Say that two of the stores are A and B. If she went to A then B, that's the same as going to B then A since you still go to the same stores, therefore, the answer is 20 / 2 = 10.
Solution 2: We need to find the number of ways to choose 2 stores from 5, we can do this by calculating ₅C₂ which equals:
5! / 2! * 3!
= 5 * 4 * 3 * 2 * 1 / 2 * 1 * 3 * 2 * 1
= 5 * 4 / 2 * 1
= 10
I believe the answer is -27
