C: 7/8
Explanation: Since we want a number that makes 4p less than 4, we need to find a number for p that is less than 1. By looking at each fraction, only 7/8 will render it less than 4
Answer:
Notice that 99 players need to be eliminated for there to be declared a winner. Notice also that every match eliminates exactly one person. Therefore, 99 matches are needed to eliminate 99 people and therefore declare a winner. The rest of the information is irrelevant. Therefore, the total number of matches is text divisible by 11.
R=5
r(r-1)=30
r²+r=30
5²+5=30
5²=30-5
5²=25
5=5
Black box = r x 2
5 x 2 = 10
Black part of card is 10 sq cm.
Answer:
837 miles
Step-by-step explanation:
Since they are on the same longitudinal line we can treat it just like a circle of radius 4000 miles, since the circles making of the longitude stay the same on a sphere. if they had the same latitude we would need an extra step of figuring out that particular circle's radius.
Now, on a circle of radius 4000 there is one point at 50 degrees on the circle and anther at 38 degrees, so now we find the arc length.
Arc length is basically taking a fraction of the circumference. if we went half way around the circle the arc length would be half the circumference. a tenth of the way makes a tenth of the circumference.
We go from 38 to 50 which is 12 degrees. out or 360 total this is 1/30 of the full circumference.
The circumference is 2*pi*r = 2*3.14*4000. so we want 1/30 of that, which means we divide it by 30.
2*3.14*4000/30 837.33 so to the nearest mile is just 837
