Mathematics

Nataly [62]3 years ago

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

5x + 7 + 4x + 2 + 90 = 180 , that is

9x + 99 = 180 ( subtract 99 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9

Then

∠ ACB = 4x + 2 = 4(9) + 2 = 36 + 2 = 38°

∠ BAC = 5x + 7 = 5(9) + 7 = 45 + 7 = 52°

-----------------------------------------------------------------------

Since the triangles are congruent then corresponding angles are congruent , so

∠ B = ∠ E

6x + 10 = 70 ( subtract 10 from both sides )

6x = 60 ( divide both sides by 6 )

x = 10

1.3( x + 2 )-( y - 6) <br> Help please
mestny [16]
Basically, we need to plug in the given values for the variables x and y into the given expression 1.3(x+2)-(y-6). First off, we can plug in all the given values into the expression, giving us 1.3(4+2)-(2-6). Now, perform the operations on the inside of the parentheses. Doing this, we get 1.3(6)-(-4). Now, we use the distributive property to simplify. This gives us 7.8+4. Finally, when we add the two numbers, we get \boxed{11.8}. Hope this helped!

What is called wage?

  • A wage is money that is paid by an employer to an employee in exchange for work.
  • The amount may be fixed for each task completed (this is called piece rate); or it may be based on time or other measurable quantity of work done.
  • Work for wages is the most common form of work.

Her real salary has fallen and her nominal salary has risen.

<u>Reason -</u> She can generate lesser goods so her real wage decreases and $200 leads to increase in nominal salary .

So,  option (d) is correct .

Kaya rented a limousine for prom. There was a one time charge of $100 dollars plus an hourly rate of $45. Her total cost for the
AleksAgata [21]
Hello!

Firstly, let's subtract the one time charge of $100, because we know for sure that Kaya is paying that:

347.50 - 100 = 247.50

Now, divide this by the hourly rate:

247.50 / 45 = 5.5

Kaya rented the limo for 5.5 (five and a half) hours. =)
