2πr= c
So π=3.14
56÷2= 28
2 x 3.14 x 28=c
87.12 x 2 = 174.24
The circumference is 174.24
Equation of a line with an slope of 1/2 that contains (-4, 7) is 
<em><u>Solution:</u></em>
We have been given a point and slope of an equation and have been asked to write it in an equation. The two forms of writing a point and slope in equation are point slope form and standard form.
The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.
To write in standard form we will first write it in point slope form and then rearrange it into a standard from.
<em><u>The formula for point slope form:</u></em>

where "m" is the slope of line
Given that "m" =
and 

Now, let us convert this equation to standard form
0.5x + 9 = y
0.5x - y = -9
Thus we have found out equation of line in point slope and standard form
Answer:
A. 3 13/20
B.3.8 kg
C.Strawberries
Step-by-step explanation:
In order to solve this we just need to find the amount of strawberries he picked, and if he picked 1 2/5 less in the morning and in the morning he picked 2 1/4, we just add that up to know how much he picked in the afternoon:

So in the afternoon he picked
.
Now he picked 5 3/10 kg of tomatoes but 1.5 were rotten, we just have to withdraw the rotten from the total:

So now we know that he picked
kg of good tomatoes.
If he picked in the afternoon and the morning 5.05 kg of strawberries, he picked more strawberries than tomatoes.
Answer:
the minimum is 410, the max is 450
Step-by-step explanation:
to find the minimum you would do 430-20 and the max would be 430+20
See the attached figure to understand the problem
we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft
tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft
AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft
the answer is
The runners are 199.85 feet apart
