The way this problem is stated is that you put 1 grain of rice on the first square, the second square has 2 grains of rice. The third square has 4 grains of rice and you keep on doubling from there. When you tell me there is a 0 square, I'm not sure what you mean.
That would mean (to me) that square 1 has 2 grains of rice
Square 2 has 4 grains of rice
Square 3 has 8 grains of rice
The table goes up to 64 squares on a chess board.
2^64 which is (rounded) to about 1.84 with 17 zeros behind the 1.84.
My calculator says the answer is 1.84 * 10^19
I think you want 
2^64<<<<<answer.
Or maybe
y =R(x) =  2^x <<<< answer.
where the domain is 0 <=x <= 64 contained in the integers.

In a parallogram the two angles on the same side ( Angle T and Angle C) equal 180 degrees

So we have 8x +29 + 2x +11 = 180

combine the like terms:
10x + 40 = 180

Subtract 40 from each side:
10x = 140

Divide each side by 10:
X = 140 /10
X = 14

Now we have X, replace X into the equation for angle C

2(14) +11 = 28 + 11 = 39 degrees

PLS HELP! URGENT!!!! A circular flower bed is 20 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the
krok68 [10]

Answer: Area of sidewalk is 217m²

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle

π is a constant whose value is 3.14

A circular flower bed is 20 meters in diameter.

radius = diameter/2 = 20/2 = 10 meters

Area of the flower bed = 3.14 × 10²

= 314m²

The circular flower bed has a circular sidewalk around it that is 3 meters wide. This means that the total diameter would be

3 + 20 + 3 = 26m

Radius = 26!2 = 13m

Total area = 3.14 × 13² = 530.66m²

Therefore, area of the sidewalk is

530.66 - 314 = 216.66

The area of sidewalk is 217m² to the nearest whole number

The width of a rectangle is 5 units less than the length. The area of the rectangle is 6 units. What is the width, in units, of
Readme [11.4K]

Answer:

The width of rectangle is 1 unit.

Step-by-step explanation:

Given:

The area of rectangle is 6 units and its width is 5 units less than the length.

So, to find the width of rectangle.

Let the length be x and the width be x-5.

Now, to find the width we put the formula of area of rectangle:

Area = length × width

6= x\times (x-5)

6=x^{2}-5x

0=x^{2}-5x-6

0=x^{2}-6x+x-6

0=x(x-6)+1(x-6)

0=(x-6)(x+1)

<em>On solving equation we get:</em>

x-6=0, x+1=0

Therefore, we take the value x=6 as it is positive value:

x-6=0

x=6

So, the width of rectangle:

Width = x-5

          = 6-5

          = 1

Therefore, the width of rectangle is 1 unit.
