Answer:
x = 10
Step-by-step explanation:
l n 20 + l n 5 = 2 l n x
ln (20×5) = ln x²
ln(100) = lnx²
100 = x²
x = +/- 10
Since logs of negative numebrs don't exist, we reject -10
Answer:
Height is 3
Step-by-step explanation:
4.24 x 4.24 x 6
Right triangle base = a + b + c
a^2 + 3^2 = 4.24^2
= a^2 + 9 = 17.98
We cross out b to subtract.
a^2 = 17.98 - 9
a^2 = 8.98
We then square √a^2 = √8.98
a = 2.996
We round up a = 3
We have found the height is 3
Since the troop made 10 times her then you multiply 950 by 10 and that will give you 9510
Check the picture below.
now, bear in mind that, there are 60minutes in 1 degree, so 23' is just 23/60 degrees or about 0.38 degrees.
and 29' is just 29/60 degrees or about 0.48 degrees.
so 16°23' is about 16.38°, and 49°29' is about 49.48°

make sure your calculator is in Degree mode.
