Find the values of x and y

arsen [322]

Answer:

x=18√6 , y=36√2

Step-by-step explanation:

${z}^{2} = 18 {}^{2} + 18 {}^{2} - 2(18)(18) \cos(90 ) \\ z = 18 \sqrt{2 } \\ \frac{x}{ \sin(60) } = \frac{z}{ \sin(30) } \\ x = 18 \sqrt{6} \\ \frac{y}{ \sin(90) } = \frac{z}{ \sin(30) } \\ y = 36 \sqrt{2}$

Answer:

$\frac{3}{4}x + \frac{1}{2}$ = One-half more than three-fourths of a number

$\frac{3}{4}-\frac{1}{2}x$ = Three-fourths minus one-half of a number

$\frac{3}{4}-(x+\frac{1}{2})$ = three-fourths minus the sum of a number and one-half

Step-by-step explanation:

Suppose x be an unknown number.

∵ 3/4th of a number = $\frac{3}{4}x$

$\frac{3}{4}x + \frac{1}{2}$ = One-half more than three-fourths of a number

Now, half of a number = $\frac{1}{2}x$

$\frac{3}{4}-\frac{1}{2}x$ = Three-fourths minus one-half of a number

Sum of a number and one-half = $x+\frac{1}{2}$

$\frac{3}{4}-(x+\frac{1}{2})$ = three-fourths minus the sum of a number and one-half

Which model shows 25%?

Stels [109]

Answer:

The first one shows 25%

In the 1st modal, a whole is divided into 4 and 1 of the 4 is selected or highlighted

And as the whole rectangle is 100% and being divided into four its becomes 100/4% and when we solve we get 100/4=25

And thus its the first modal that shows 25%

In the second case its divide into 3 boxes so.. 100/3% and when we solve we get 33.3333333.......and this is not what we want

THEREFORE, THE CORRECT ANSWER IS 1ST MODAL

What is the first step in solving the equation: 3(x+2) = 12?

yanalaym [24]

Answer:

Divide by 3 on both sides.

Step-by-step explanation:

Original Expression: 3(x+2) = 12

Divide by 3 on both sides: x+2 = 4

Subtract 2 from both sides: x=2
