Answer:
The minutes wouldn't it be hours?
Step-by-step explanation:
Look at the digit to the right of the required number. If it is a 5 or greater, add 1 to previous digit.
If it is less than 5, leave the previous digit unchanged. In either case, drop all the remaining digits. Example: Round off this decimal 7.253896 to three decimal digits.
Answer. 7.253896approximately7.254
(The wavy equal sign approximately means "is approximately equal to.")
To round off to three decimal digits, we must look at the digit in the fourth place. The digit in the fourth place is 8 (greater than 5). Therefore, we add 1 to the previous digit 3.
the fencing is the perimeter to the tree, then we can use the formula of the perimeter of a circle to replace this value

now we can solve r from the formula to know the radious

we can use 3.14 to pi

the value of the radio is 3 feet
now we can use the formula of the area of the circle to calculate the total area

and replace the known value of the radious and pi

<em>the area is 28.26 square feet</em>
Answer:
its about 2
Step-by-step explanation:
Simplifying
7(3x + 5y) = 0
(3x * 7 + 5y * 7) = 0
(21x + 35y) = 0
Solving
21x + 35y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-35y' to each side of the equation.
21x + 35y + -35y = 0 + -35y
Combine like terms: 35y + -35y = 0
21x + 0 = 0 + -35y
21x = 0 + -35y
Remove the zero:
21x = -35y
Divide each side by '21'.
x = -1.666666667y
Simplifying
x = -1.666666667y
