Answer:

2.5 counters

Step-by-step explanation:

On the right, there are 8 spheres. Since the scale is balanced, we can assume there is an equivalent of 8 spheres on the left side. We can clearly see three spheres (in red), so we'll subtract that from the 8. The canisters (blue) are the same weight, and make up 5 spheres togther. So, divide by 2, and your answer is the blue canister is equal to 2.5 spheres/counters.

You want to draft a four ­player tennis team. There are eight players to choose from. How many different teams can you form?
Butoxors [25]

We want to make a 4 players team, and there are total 8 players. As we know the order of selection does not matter in a team of players, only the combination of players matters.

So we would use concept of Combinations and It will be choose 4 out of 8 players.

The formula for Combination is given as follows :-

nCr = \frac{n!}{r!*(n-r)!} \\\\
Choose \;4 \;out \;of \;8 \;players \\\\
8C4 = \frac{8!}{4!*(8-4)!} = \frac{8!}{4!*4!} \\\\
8C4 = \frac{8*7*6*5*4*3*2*1}{(4*3*2*1)*(4*3*2*1)} = \frac{8*7*6*5}{4*3*2*1} =\frac{1,680}{24} = 70 \;combinations

Hence, Total number of different teams = 70 combinations.

What is the area of this figure? Enter your answer as a decimal in the box. cm² A parallelogram with a length of 11 cm. A triang
Art [367]
Given:
Parallelogram length = 11 cm
triangle atop the parallelogram : short leg = 7 cm
Right triangle inside the parallelogram : long leg = 9cm

Area of parallelogram = base * height
A = 11cm * 9cm
A = 99 cm²

Area of a triangle atop the parallelogram:
A = ab/2
A = (11cm * 7cm)/2
A = 77 cm² / 2
A = 38.5 cm²

Total area of the figure
99 cm² + 38.5 cm² = 137.5 cm²
