Answer:
7/8 or 0.875
Step-by-step explanation:
If you want it in fraction form, it's 7/8. If you want it in decimal form, it's 0.875.
The area of the red piece of paper is A= 4(2*4)= 4*8= 32 in^2.
The area of the blue piece of paper is A= 3*7=21 in^2. You subtract 21 from 32 and the difference is 11. So 11in^2 is visible.
Answer:
40.5 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees, so to solve this all you need to do is add the two numbers you have and subtract them from 180.
62.5+77+x=180
139.5+x=180
-139.5 -139.5
x=40.5
Answer: 494991
Step-by-step explanation:
Answer:
A regional soccer tournament has 64 participating teams.
In the first round of the tournament, 32 games are played.
In each successive round, the number of games played decreases by 1/2.
Part A:
We know;



So, we get;
The rule for the number of games played in the nth round is given by:

where 
Part B:
As in each successive round the rounds are decreasing by 1/2 we have.
round 1 = 32
round 2 = 16
round 3 = 8
round 4 = 4
round 5 = 2
round 6 = 1
So, the total number of games played in the regional soccer tournament are:
