Each square on olivias chessboard is 11 square centimeters. a chessboard has 8 squares on each side. To the nearest tenth, what

levacccp [35]

The answer is 9 centimeters rounded up. You multiply 11 squares by 8 squares which is 88(9 rounded up) and the answer is the same on each side which means the width is 9 centimeters rounded up.

You can use the sum of angles identities, then rearrange to put the result in the form of tangents.

$\displaystyle\frac{\sin{(x+y)}}{\sin{(x-y)}}=\frac{\sin{(x)}\cos{(y)}+\cos{(x)}\sin{(y)}}{\sin{(x)}\cos{(y)}-\cos{(x)}\sin{(y)}}\\\\=\frac{\left(\frac{\sin{(x)}\cos{(y)}+\cos{(x)}\sin{(y)}}{\cos{(x)}\cos{(y)}}\right)}{\left(\frac{\sin{(x)}\cos{(y)}-\cos{(x)}\sin{(y)}}{\cos{(x)}\cos{(y)}}\right)}\\\\=\frac{\tan{(x)}+\tan{(y)}}{\tan{(x)}-\tan{(y)}}$

Mrs. Magee's farm covers 14 1/3 acres. She grows corn on 5/8 of her farm. On how many acres of land does Mrs. Magee grow corn?

Aleonysh [2.5K]

C. 8 23/24. One way you can solve this is by dividing 14 1/3 by 8, because it is the denominator of 5/8, then multiplying the quotient by 5, because it is the numerator of 5/8. (14 1/3 / 8) x 5 = 8 23/24

Nathaniel measured the height of one shelf on his bookcase. He wants to know which books will fit on the shelf. The shelf is 22.

UkoKoshka [18]

PART A - So the ruler is 22.86 centimeters tall, and after measuring with an inch ruler, is also 9 inches tall.
ruler = 22.86cm
ruler = 9 in
You can equate 22.86cm and 9in because they both equal the length of the ruler (transitive property).
22.86cm = 9in
Then you can write a proportionality equation.
$\frac{22.86cm}{9in} = \frac{x}{1in} \\$

Part B -
Cross multiplying,
$(9in)x = (22.86cm)1 \\ 
x = \frac{22.86cm}{9in}= 2.54cm/in$

Part C - We can use something called dimensional analysis - multiplying 12 cm by (1in/2.54cm) - in order to change the units from inches to cm. This is possible because 1in = 2.54cm, the fraction 1in/2.54cm = 1. And also the units cm will cancel out.
$\frac{12cm}{1} * \frac{1in}{2.54cm} = 4.72in$
