What is the area of the triangle given below?
2
11
O A. 11 sq. units
B. 13 sq. units
C. 8 sq. units
O D. 22 sq. units

Answer: A

Step-by-step explanation: I would say A, because on the left, you have your domain, and the right is your range and codomain.

Answer:

C) 60 degrees

Step-by-step explanation:

An equilateral triangle has all equal angles. We know that all the angles of a triangle add up to 180 degrees. Therefore 45+45+45=180 giving you an equilateral triangle angle measure.

Answer:

58.208 times 8 equals 465.664 rounded down to 465.66

Step-by-step explanation:

Answer:

$465.66

Step-by-step explanation:

First, we are buying 8 uniforms. Therefore, the total price on a normal day would be 8x68 = $544

However, on this day, there is a 20% discount. In other words, we are only paying 80% of the original price as percentages are always out of 100.

The price after the sports discount will be 544x0.8 = $435.2

On top of this, we have to pay a sales tax of 7 percent. The 7 percent is an additional cost to the discounted price of 435.2, hence we add 0.07 (7 percent in decimals) onto 1 (100% in decimals).

This gives us 435.2 x ( 1 + 0.07 )  = 465.664.

Because currency is to 2 decimal points (1 cent), the final answer will be 465.66, or 465 dollars and 66 cents.

Answer:

#2 is combine like terms.

Step-by-step explanation:

Answer:

34 trabajadores.

Step-by-step explanation:

Supongamos que el empresario tiene N trabajadores, y tiene la cantidad de dinero D para pagarles cada día.

Si el empresario decide pagarle 50 a cada trabajador le faltan 110.

Esto se puede reescribir como:

50*N = D + 110

(50 por número de empleados es igual que el dinero que tiene más lo que le falta para pagar)

También sabemos que si pagara 45 a cada empleado, le sobraría 60.

Esto se puede reescribir como:

45*N = D - 60

Entonces tenemos dos ecuaciones:

50*N = D + 110

45*N = D - 60

Para resolver esto, el primer paso es aislar una de las variables en una de las ecuaciones, en este caso aislaré D en la segunda ecuación.

45*N + 60 = D

Ahora podemos reemplazar esto en la primer ecuación y resolver para N

50*N = (45*N + 60) + 110

50*N = 45*N + 170

50*N - 45*N = 170

5*N = 170

N = 170/5 = 34

El empresario tiene 34 trabajadores.

Answer:

69.28 cm

Step-by-step explanation:

i used a calculator but the steps you take to solve this are...

1. Multiply the length of one side by the length of the other.

             80x60 = 4,800

2. Square that number to get the hypotenuse

              [tex]\sqrt48000[/tex]

Answer:

x = 20% acid = 60 ml

y = 45% acid = 40 ml

Step-by-step explanation:

Let

x = 20% acid

y = 45% acid

x + y = 100 (1)

.20x + .45y = .3 ×100

.20x + .45y = 30 (2)

From (1)

x + y = 100 (1)

x = 100 - y

Substitute x = 100 - y into (2)

.20x + .45y = 30

.20(100 - y) + .45y = 30

20 - .20y + .45y = 30

- .20y + .45y = 30 - 20

.25y = 10

y = 10/.25

y = 40 ml

Substitute y = 40 into (1)

x + y = 100

x + 40 = 100

x = 100 - 40

x = 60 ml

x = 20% acid = 60 ml

y = 45% acid = 40 ml

Answer:

Answer is A -  Angles that are congruent are complementary to the same angle.

Answer:

D

Step-by-step explanation:

Mathematically, for us to have a right triangle, Pythagoras’ theorem must be obeyed

From the theorem, the square of the hypotenuse (longest side) equals the sum of the squares of the two other sides

Let us take a look at the given set of numbers:

2 square is not same as 1 squared + 1 squared

9 squared is not equal to 3 squares + 5 squared

7 squared is not equal to 4 squared + 3 squared

But;

root 2 squared equals 1 squared plus 1 squared and that is our answer

Answer:

-3 = N

Step-by-step explanation:

2-2N=3N+17

Add 2N to each side

2-2N+2N=3N+2N+17

2 = 5N +17

Subtract 17 from each side

2-17 = 5N+17-17

-15 = 5N

Divide each side by 5

-15/5 = 5N/5

-3 = N

Answer:

N= -3

Step-by-step explanation:

First, bring 3N on to the left side by subtracting 3N with 2N

2-2N-3N=17

Then, move 2 to the right side by subtracting 17 and 2: -2N-3N= 17-2

Solving the like terms gives us -5N= 15

N= 15/-5

N= -3

Factoring is an important process that helps us understand more about our equations. Through factoring, we rewrite our polynomials in a simpler form.

It is used in asset (stock) valuation. It is used in bond trading and mortgage calculations.

Step-by-step explanation:

Answer:

The angels are 60 degrees and 120 degrees

Step-by-step explanation:

The sum of two supplementary angels equal 180 degrees.

So, lets look at the ratio: 6:3

We then add 6 and 3 together which gives us 9.

Then you put it in this equation:

9x = 180

x= 20

- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.

- In this case, we multiply 20 by 6 = 120 degrees

- Then we multiply 20 by 3 = 60 degrees.

(We can check our answer by: 120 + 60 = 180 degrees) :)

Answer:

(31, 2); Substitution.

Step-by-step explanation:

x - 3y = 25

Use SUBSTITUTION by setting everything in the above equation equal to x...

x = 3y + 25

2(3y +25) + y = 64

6y + 50 + y = 64

7y + 50 (-50) = 64 (-50)

7y = 14

y = 2

Then, substitute y = 2 into the original equation.

x - 3(2) = 25

x - 6 = 25

x = 31

(x, y) = (31, 2)

Answer:

x = 4

Step-by-step explanation:

By intersecting secants theorem:

Answer: S=5r+85 i think try it out

Step-by-step explanation:

Answer:

The second statement.

Step-by-step explanation:

The function S = 5r + 13 means that the Total = 5 * Tickets + 13 Admission

So if Camille bought 13 tickets, the + 13 at the end means that no matter what, she had 13 dollars admission.

Answer:

Zero

Step-by-step explanation:

Solve the equation by subtracting 8z from both sides:

8z − 5 = 8z

-5 = 0

-5 [tex]\neq[/tex] 0

This is a false statement, because -5 is not equal to zero.

This means that there are no solutions to the equation.

So, the equation has zero solutions

Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.
