Answer:

15 feet

Step-by-step explanation:

The area of a circle is pi*r^2, and we're using 3.14 as pi, so we get: area= 3.14 r^2

We plug 706.50 into the equation and get:

706.50 = 3.14 r^2

Divide both sides by 3.14:

225 = r^2

Square root both sides:

15 = r

Answer:

15 feet of water spread

Step-by-step explanation:

Area of the circular pattern is 706.50 sq. feet

Area = A = π r^2 = (3.14)* r^2

706.50 = (3.14)* r^2

r^2 = 706.50 / 3.14

r = root (225)

r = 15 feet

A team of scientists estimate the current number of butterflies in a park to be 20 thousand. The butterfly population is expecte

Jlenok [28]

Answer:

Option B is the correct answer.

Explanation:

Current number of butterflies in the park = 20 thousand.

Rate of increase of butterfly population = 4% = 0.04

The population of butterfly after 1 year = 20+0.04*20 = 20*1.04

The population of butterfly after 2 years = 20*1.04 + 20*1.04*0.04 = 20*1.04*1.04

The population of butterfly after 3 years = 20*1.04*1.04 + 20*1.04*1.04*0.04 = 20*1.04*1.04*1.04

So, population of butterfly after n years = 20*(1.04*1.04*1.04* .... n times)

$= 20*1.04^n$

Option B is the correct answer.

Find the other endpoint given endpoint (-10,7) midpoint (6,2)

Makovka662 [10]

Answer:

(22;-3)

Step-by-step explanation:

if to calculate the coordinates of the given midpoint it needed to use:

$x_{midpoint}=\frac{x_{endpoint1}+x_{endpoint2}}{2};$

$y_{midpoint}=\frac{y_{endpoint1}+y_{endpoint2}}{2};$

then to calculate the coordinates of endpoint2, it needed to perform the substitution:

$\frac{-10+x_{endpoint2}}{2}=6,$

$2=\frac{7+y_{endpoint2}}{2},$

finally:

$x_{endpoint2}=22;$

$y_{endpoint2}=-3.$

QUICK I NEED HELP PLEASE!

seraphim [82]

Assuming you meant is $- \frac{3}{5} x+ \frac{1}{5} \ \textgreater \ 720$

The answer would be :
$- \frac{3}{5} x\ \textgreater \ 719.8$

$x \ \textless \ \frac{719.8}{ \frac{-3}{5} }$
$x\ \textless \ 719.8 *( \frac{-5}{3} )$
$x\ \textless \ \frac{-3599}{3}$

Hope this helps !

Gavin was thinking of a number. Gavin halves the number and gets an answer of 34.3. Form an equation with x as information.

Lostsunrise [7]

Gavin's number is 68.6

Equation: 1/2(x) = 34.3

Use inverse operations on both sides.

1/2(x) = 1x or x = 34.3(2)

34.3(2) = 68.6

Thus, x equals 68.6
