Remark
Good golfers never slice the ball. They occasionally may hook it but they seldom if ever slice it. If he only slices it 10 years and his shot is 275 yards from the tee, his straight line distance from the hole is hardly noticeable from 478 - 275 = 203. It will take a couple of decimal places I would think to notice the difference.
If he shot the first shot straight down the middle of the fairway, his distance to the flag would be exactly 203 yards. Since he is 10 yards off the center line. You need to employ the Pythagorean theorem twice. The first time to figure out what that slice has cost him. His tee shot is 275 yards. The straight line distance is (b).
a=10
b = ??
c = 275
a^2 + b^2 = c^2
10^2 + b^2 = 275^2
100 + b^2 = 75625
b^2 = 76625 - 100
b^2 = 76525
b = sqrt(76525)
b = 274.82
So his straight line distance is 475 - 274.82 = 200.18
Now what you need to do is take another shot from 10 yards of the straight line distance.
a = straight line distance = 200.18
b = 10
c = actual distance
a^2 + b^2 = c^2
200.18^2 + 100 = c^2
40072.78 + 100 = c^2
c = sqrt(40172.78)
c = 200.43 yards. Answer

Step-by-step explanation:
Answer:
9465 people/square mile.
Step-by-step explanation:
If there are 646,449 people in 68.3 square miles for the district of columbia, the unit rate in terms of people per square mile for the District of Columbia will be expressed as shown;
646,449 people = 68.3 square miles
x people = 1 square mile
Cross multiply
646,449 people * 1 square mile = 68.3 square miles * x people
x = 646,449 people * 1 square mile/68.3 square miles
x = 646,449/68.3 square miles
x = 9464.8463 square miles
x ≈ 9465 people/square mile.
<em>Hence the unit rate in terms of people per square mile for the District of Columbia is approximately 9465 people.</em>
Multiply 25 by .04 (change percent to decimal by moving the decimal two places to the right) You will get one. So four percent of 25 is one.
25x.04=1
