Answer:
1071202 miles
Step-by-step explanation:
Circumference of planet A = 
We are given that Planet A has a circumference of 93,480 miles.


Since we know that twice the radius is diameter
So, 
Now we are given that Its moon has a diameter that is approximated to be 1/ 8 that of Planet A.
So, 





Hence the approximate distance of the moon from Planet A is 1071202 miles
Answer:
Step-by-step explanation:
6) triangle ABC is similar to triangle DEC. It means that
AB/DE = BC/EC = AC/DC
Therefore,
6/21 = 10/y
Cross multiplying, it becomes
6y = 210
y = 210/6
y = 35
Also
6/21 = x/28
Cross multiplying, it becomes
6 × 28 = 21x
21x = 168
x = 168/21
x = 8
7) triangle JKL is similar to triangle NMP. It means that
JK/NM = KL/MP = JL/NP
Therefore,
49/14 = (9x + 1)/(x + 5)
Cross multiplying, it becomes
49(x + 5) = 14(9x + 1)
49x + 245 = 126x + 14
126x - 49x = 245 - 14
77x = 231
x = 231/77
x = 3
The tax is 6.5% OF the listed price. "OF" in math means multiply.
First convert the percentage to a decimal
6.5% = .065
Then multiply .065*813.95 = 52.90675. This is the tax.
Simply add the tax onto the cost
813.95 + 52.90675 = $866.86 (rounded)
Its independent because it does not depend on the answer before
