What is the geometric mean between 9/16 and 25/36

Mathematics

sergiy2304 [10]3 years ago
6 0

Answer:

5/8

Step-by-step explanation:

Geometric mean is found by multiplying the n number of values and then taking the n-root.

To do this with these numbers, sqrt((9/16)*(25/36)) = (3/4)(5/6) = (1/4)(5/2)= 5/8

I hope this helps! :)

Solve the equation x – 5 = 0.1(x + 5) for x. Round your answer to the nearest hundredth.
Nadusha1986 [10]

Answer:

x=6.111....

Step-by-step explanation:

x-5=0.1(x+5)

distribute 0.1 into (x+5)

x-5=0.1x+0.5

subtract 0.1x on both sides

x-0.1x-5=0.5

combine like terms

0.9x-5=0.5

add -5 on both sides

0.9x=5.5

divide both sides by 0.9

\frac{0.9x}{0.9} =\frac{5.5}{0.9}

x=55/9 or 6.11111.......

hope this helps

A certain forest covers an area of 4900km^2. Suppose that each year this area decreases by 7.25%. What will the area be after 5
ratelena [41]

Each year, the forest decreases in area by 7.25%, which means that 92.75% of the forest remains each year.

With this, we can write a basic exponential decay equation:

4900*(0.9275)^t

Where t is the number of years past.

When you plug in 5 for t, the result shows that 3363.3005km^2 offorest will remain.

Hope this was helpful!
