2/3 because 8/12 divided down is 4/6 which reduced again is 2/3

8/12 but you have to reduce which is 4/6 but then you reduce which is 2/3 and 2/3 can't be reduced so it is 2/3.

a photograph that measures 20 cm by 15 cm is enlarged so that its length becomes 28 cm. what does the width become?

Answers

$(width)/(distance) = (15)/(20) = (3)/(4)$

This means that ,assumining the dimensions stay the same, the width will be equal to three quaters of the length

∴ When length=28cm
width = 0.75 × 28 = 21cm

the width becomes 21 centimeters hope this helps:)

Solve for x and y please!

Answers

Answer:

$x = 8$

$y=2√(3)$

Step-by-step explanation:

The figure is composed of 3 Right triangles. To find the values of the variables x and y we use the Pythagorean theorem to propose one equation.

$x^2 =4^2 + (4√(3))^2$

Now we solve for x

$x=\sqrt{4^2 + (4√(3))^2}$

$x=√(16 +16*3)\n\nx=√(64)\n\nx=8$

Let's call z at the angle opposite to y

Then we have that:

$sin(z) =(opposite)/(hypotenuse)$

Where

$hypotenuse = 8$

$opposite=4$

$sin(z) =(4)/(8)$

$z=sin^(-1)((1)/(2))$

$z=30$

Now we use this angle to find the length y

$sin(z) =(opposite)/(hypotenuse)$

Where in this case

$hypotenuse = 4√(3)$

$opposite=y$

$z=\°30$

$sin(30\°) =(y)/(4√(3))$

$y=sin(30\°)*4√(3)$

$y=2√(3)$

How many 2/3 pieces can you cut from a 10 foot long board

Answers

I told you in my answer that I was writing that you have to remember that in math any whole number converted to a fraction is over 1. So make the 10 a 10/1.

10/1 divided by 2/3 copy change flip.

10/1 x 3/2 multiple across 30/2 divide that answer is 15. You can cut 15 boards that are 2/3 in length from a 10 foot long board.
