We know that
[the circumference of a circle]=2*pi*r
r=2 ft
[the circumference of a circle]=2*pi*2------> 12.56 ft
if 360° (full circle) has a length of-----------> 12.56 ft
72°---------------------------------> X
x=72*12.56/360-------< x=2.512 ft
1 ft----------> 12 in
2.512 ft-----> x
x=2.512*12------> x=30.14 in-----> x=30 in
the answer is
30 in
Answer:
$750
Step-by-step explanation:
We can set up the equation 30x + 50y = z where x = the amount of small dogs, y = the amount of big dogs, and z = the total.
After plugging in the x and y values to solve for z, we are left with the following equation:
30(15) + 50(6) = 750
the answer to your question is 333.333 dollars
The number of problems Shelly has to complete is 25 problems
<h3>Fraction:</h3>
- Total problems = x
- Number of problems completed = 10
- Number of problems to complete = 2/7x
x = 10 + 2/7x
x - 2/7x = 10
(7x-2x)/7 = 10
5/7x = 10
x = 10 ÷ 5/7
= 10 × 7/5
= 70/5
x = 35 problems
So,
Number of problems to complete = Total problems - completed problem
= 35 - 10
= 25 problems
