Answer:

30 ft^2

Step-by-step explanation:

Area of square = 12 x 12 = 144

Area of circle = 3.14 x 6^3 = 3.14 x 36 = 113.04

So area of the remaining board = 144 - 113.04 = 30.96

Solve to find the answer of blue pills Mr body took: number of blue pills, b, mr mattics give him was 3 more than the number of

barxatty [35]

Answer:

Mr body took 9 blue pills

Step-by-step explanation:

Total number of pills consumed = 17

Number of blue pills, b = 11

Number of blue pills, b = g + 3

So that,

b = g + 3

11 = g + 3

g = 8

Total number of pills recommended = b + g

= 11 + 8

= 19

Total number of pills consumed = 17

Thus,

Number of blue pills consumed = 17 - 8

= 9

Therefore, Mr body took 9 blue pills.

Gnoma [55]

Answer:

Equation: $20=4x$ or $x=\frac{20}{4}$

Solution: $x=5$

Step-by-step explanation:

The formula that is used to calculate the perimeter of a square is:

$P=4s$

Where "s" is the side lenght the square.

Knowing that Xin used 20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

$P=20\\\\s=x$

Then, you can susbtitute values into the formula $P=4s$ :

$20=4x$

Finally, you must solve for "x" in order to find its value.

This is:

$\frac{20}{4}=x\\\\x=5$
