The answer would be 3.9 because the nine is in the tenths place and the two is not equal to or greater than five so it stays the same

It is 3.9 because none of the other numbers are over 5 so the 9 doesn't become a 10. Even though there is a six the 1 becomes a 2 and that is all that happens<span />

There are 8 rows and 8 columns, or 64 squares

Complete Question:

There are 8 rows and 8 columns, or 64 squares on a chessboard.

Suppose you place 1 penny on Row 1 Column A,

2 pennies on Row 1 Column B,

4 pennies on Row 1 Column C, and so on …

Determine the number of pennies in Row 1

Determine the number of pennies on the entire chessboard?

Answer:

255 in the first row

18,446,744,073,709,551,615 in the entire board

Step-by-step explanation:

Given

$Rows = 8$

$Columns = 8$

Solving (a): Number of pennies in first row

The question is an illustration of geometric sequence which follows

$1,2,4....$

Where

$a =1$ --- The first term

Calculate the common ratio, r

$r = \frac{T_2}{T_1} = \frac{4}{2} = 2$

The number of pennies in the first row will be calculated using sum of n terms of a GP.

$S_n = \frac{a(r^n - 1)}{n - 1}$

Since, the first row has 8 columns, then

$n = 8$

Substitute 8 for n, 2 for r and 1 for a in $S_n = \frac{a(r^n - 1)}{r - 1}$

$S_8 = \frac{1 * (2^8 - 1)}{2 - 1}$

$S_8 = \frac{1 * (256 - 1)}{1}$

$S_8 = \frac{1 * 255}{1}$

$S_8 = 255$

Solving (b): The entire board has 64 cells.

So:

$n = 64$

Substitute 64 for n, 2 for r and 1 for a in $S_n = \frac{a(r^n - 1)}{r - 1}$

$S_{64} = \frac{1 * (2^{64} - 1)}{2 -1}$

$S_{64} = \frac{(2^{64} - 1)}{1}$

$S_{64} = \frac{(18,446,744,073,709,551,616 - 1)}{1}$

$S_{64} = \frac{18,446,744,073,709,551,615}{1}$

$S_{64} = 18,446,744,073,709,551,615$

4+m/3 = 5/6 solve for m<br> Show your work pls<br> It is URGENT

Likurg_2 [28]

Answer:

M = - 19/2 or in decimal form - 9.5

Step-by-step explanation:

1. Subtract 4 from both sides.

M/3 = 5/6 - 4

2. Simplify

5/6 − 4 to −19/6

3. Multiply both sides by 3.

M = - 19/6 x 3

4. Simplify 19/6 × 3 to 57/6

M = -57/6

5. Simplify 57/6 to 19/2

M = - 19/2

Find the sine ratio of angle Θ. Hint: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no s

uysha [10]

Answer:

12/13

Step-by-step explanation:

Sine is equal to Opposite over hypotenuse. The opposite side of an angle in a triangle is the one that it does not touch. AB is the opposite side of C here.

The hypotenuse is the line that does not create the right angle. In this triangle that is BC.

We already know the measurements of these sides, so we just need to plug them in.

SinC = 12/13
