Here we are give the value for π and Diameter of the circle fence

π=3.14

Diameter = 16

Radius = Diameter/2

2πr = 2(3.14)(8)

Circumference = 50.27

Now to fine the square fence length so we do 16*4 = 64

64-50.27 = 13.73 in

Therefore, the square fence is 13.73 inches longer than the circle fence

two species of birds are being compared. Species A can fly 18.9 miles in 42 minutes, while species b can fly 20.3 miles in 58 mi
AysviL [449]
Species A: 18.9 miles / 42 minutes = 0.45 miles per minute
Species B: 20.3 miles / 58 minutes = 0.35 miles per minute
Therefore, species A is faster and flies at a speed of 0.45 miles per minute
(27 mph)
0.45 x 60 = 27 mph

Darya [45]
She needs more then 472 and has 296 so she still needs 176 because 472-296=176
Each bracelets is 4 so then 176/4 is 44
1. She needs to sell 44 more bracelets,45 if she needs more than 472
2 the inequality would be x>=44 bracelets

Please do this for me <br><br> I am very lazy
Alexandra [31]

First, let's turn all the numbers into improper fractions so that we can find the answer easier.

-2 \frac{1}{4} = r - \frac{4}{5}

-\frac{9}{4} = r - \frac{4}{5}

Now we have to isolate 'r'.

First, we have to make sure that the variable is on one side and all the numbers are on the other side.

To do this, we have to add \frac{4}{5} to both sides.

In order to do this, we need to ensure that both fractions have a common denominator.

-\frac{9}{4} = r - \frac{4}{5}

Ensure that the denominators are the same:

\frac{45}{20} = r - \frac{16}{20}

\frac{45}{20} + \frac{16}{20} = r

\frac{61}{20} = r

Good luck!
