Answer:
a=32/a
Step-by-step explanation:
Distribute:
8 x 4= 32 8 x -a = -8a
32-8a=2a
add 8a to both sides:
32-8a+8a=2a+8a
Combine like terms:
32=10a
divide by 10 to get a by itself:
32/10=a
flip it around
a=32/10
In 2014, the population of Hong Kong was estimated to be approximately 7,112,688 people. The city covers an area of approximately 426.25 square miles.
The number of people = 7,112,688
City area = 426.25 square miles
The population density =
=
= 16686.65806 people per square mile
The population density of Hong Kong in 2014 is 16687.
The percentages for each acid are:
- 0% acid ⇒ percentage disolved = 0%
- 33% acid ⇒ percentage disolved = 1%
- 66% acid ⇒ percentage disolved = 2%
- 100% acid ⇒ percentage disolved = 4.2%
<h3>
How to get the percentages?</h3>
Here we just need to use the given formula:
For the 0% acid, the initial and final mass are the same:
initial mass = final mass = 10.3g
Then the percent dissolved is:
For the 33% acid we have:
- initial mass = 10.1g
- final mass = 10g
Then:
For the 66% acid:
- initial mass = 10g
- final mass = 9.8g
for the 100% acid:
- initial mass = 9.9g
- final mass = 9.5g

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
Vas happenin!!
The last option is correct… She flipped the Y values and the X values it would be 4-12÷9-7
Hope this helps
