Answer:

$654

Step-by-step explanation:

Let the amount of money Marlina's received for her salary be x.

We know that she spent 1/2 of her salary on rent and then $338 on her electric and water bill. So, after this, she will have:

x-\frac{1}{2}x-338

Left of her salary.

Next, she spent one half of what was left. So, it will be one-half of the equation. Therefore, she will have spent:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)

Finally, she spent $56 for gas. So, we will subtract 56:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)-56

And we know that after all of the expenses, she will have $102 left. Therefore:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)-56=102

We want to know how much Marlina spent on rent. So, let's find her salary x first.

First, let's distribute the 1/2:

x-\frac{1}{2}x-338-\frac{1}{2}x+\frac{1}{4}x+169-56=102

Combine like terms:

(x-\frac{1}{2}x-\frac{1}{2}x+\frac{1}{4}x)+(-338+169-56)=102

Evaluate:

\frac{1}{4}x-225=102

Add 225 to both sides:

\frac{1}{4}x=327

Multiply both sides by 4:

x=\$ 1308

Therefore, Marlina received a total of $1308 for her salary.

We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:

r=\frac{1}{2}(1308)=\$ 654

And we're done!

triangle ABC is shown in the diagram. The links of the sides are in terms of the variable n, where n >4. complete the inquali
Blababa [14]

9514 1404 393

Answer:

  m∠B < m∠A < m∠C

Step-by-step explanation:

We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.

For n = 4, the side lengths are ...

  a = 2(4) = 8

  b = (4) +3 = 7

  c = 3(4) -2 = 10

The longest side is opposite the largest angle, so the ordering of angles is ...

  m∠B < m∠A < m∠C

_____

The triangle inequality requires all of these inequalities be true:

  • a+b > c   ⇒   3n+3 > 3n-2 . . . always true
  • b+c > a   ⇒   4n+1 > 2n   ⇒   n > -1/2
  • c+a > b   ⇒   5n-2 > n+3   ⇒   n > 5/4

That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5). What are the coordinates after the two transformations: Translati
igor_vitrenko [27]

Given :

Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5).

To Find :

The coordinates after the two transformations:

a) Translation (x, y) --> (x - 2, y - 1) .

b)  Rotation: 90 degrees counterclockwise at the origin.

Solution :

Applying transition a) , we get :

R'(2-2,3-1) , S'(-2-2,1-1) , T'(-1-2,5-1)

R'( 0, 2) , S'( -4 , 0), T'( -3, 4)

Now , When any point ( h , k ) is rotated 90° counterclockwise about the origin, the new points are (-k , h) .

So , R''( -2, 0) , S''( 0, -4 ) , T''( -4 , -3 ) .

Therefore , the coordinates after transformations are

( -2, 0) ,( 0, -4 ) , ( -4 ,-3 ) .

Hence , this is the required solution .
