The sum of the interior angles of a triangle (half the rhombus in this case) is 180. Because of the properties of a rhombus, z and x will be equal to each other. Therefore, $124 + z + z = 180$ .
$124 + z + z = 180$
$124 + 2z = 180$
$2z = 56$
$z = 28$
Thus, z is equal to 28.

The sum of the reciprocals of two consecutive even integers is 3/4 Find the two integers.

Vedmedyk [2.9K]

$\Large{ \underline{ \underline{ \bf{ \orange{Solution:}}}}}$

Let one of those even numbers be x, Then other even number would be x + 2.

According to question,

⇛ Their reciprocal add upto 3/4

So, we can write it as,

⇛ 1/x + 1/x + 2 = 3/4

⇛ x + 2 + x / x(x + 2) = 3/4

⇛ 2x + 2 / x² + 2x = 3/4

Cross multiplying,

⇛ 3(x² + 2x) = 4(2x + 2)

⇛ 3x² + 6x = 8x + 8

⇛ 3x² - 2x - 8 = 0

⇛ 3x² - 6x + 4x - 8 = 0

⇛ 3x(x - 2) + 4(x - 2) = 0

⇛ (3x + 4)(x - 2) = 0

Then, x = -4/3 or 2

☃️ It can't be -4/3 because it is fraction and negative number. So, x = 2

Then, x + 2 = 4

✤ So, The even numbers are 2 and 4.

PLEASE HELP ; I need help on this ? I am confused .

256,000-2.56*100,000
Since there are 6 digits in 256,000, it is 2.56*100,000 becuase 100,000 also has 6 digits.
2.56*100,000=2.56*10^5
Since there are 5 zeroes in 100,000, it is 10^5.
256,000=2.56*100,000=2.56*10^5
First box: 100,000
Second box: 5

Write an equation to convert a diamond's weight in carats to its weight in milligrams. Be sure to define your variables.

kolbaska11 [484]

Carats, known as ct, is a measure of weight used for gemstones.One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. So, the equation would be as follows:

m = c x 200

where m is the mass in units of milligrams and c is the weight in units of carats.

Hope this helped. Have a nice day.
