Answer:
or 
Step-by-step explanation:
We can convert from mixed numbers to decimal numbers:

Since they cleaned up 8.2 kilograms of trash in one neighborhood and 11.5 kilograms in another neighborhood, the total trash they cleaned up was:

We know that they sent 1.25 kilograms to be recycled. Then, in order to calculate how many kilograms of trash they threw away, we must subtract the total kilograms of trash they cleaned up and the kilograms they sent to be recycled.
Then:
or 
Angle a is 35 degrees angle b is 55 degrees angle c is 110 degrees
This division question is asking how many 1/4 you can fit into 50 1/2.
We can fit 4 of them into 1 whole (4 x 1/4 = 1)
We can fit 8 of them into 2 wholes (8 x 1/4 = 2)
and so on.
But we have 50 1/2 wholes, so we would need 50 1/2 x 4.
The new number sentence is 50 1/2 x 4.
Answer:
The circumference of circle is: 31.714 cm
Step-by-step explanation:
Let C be the circumference of the circle
And A be the area of circle
It is given that:

We have to find the radius first so that it can be used to find the circumference
The area of circle is given by the formula:

Putting the value of area

Taking square root on both sides

Now

Putting the value of radius

Hence,
The circumference of circle is: 31.714 cm
