O A. 11 sq. units
B. 13 sq. units
C. 8 sq. units
O D. 22 sq. units

Answers

Answer 1

Answer:

Area = 11 sq. units

Step-by-step explanation:

Base = 11 units

height = 2 units

Area = 1/2 × base × height

Area = 1/2 × 11 × 2

Area = 11 sq. units

Answer 2

11 square units is the area of the triangle , option A is correct.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

The formula to find area of triangle is half times of base and height

Given Base is 11 units

height is 2 units

Area = 1/2 × base × height

Plug in the values of base and height

Area = 1/2 × 11 × 2

Area = 11 sq. units

Hence, 11 square units is the area of the triangle , option A is correct.

help plz thank you

Answers

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

"sports discount" has uniforms for 68$. They are offering a 20% discount on each uniform, and a 7 percent sales tax will be applied to the discount price. What would be the final cost for eight uniforms after the discount and sales tax

Answers

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.

What is the measure of each angle of an equilateral triangle?
A. O 90°
B. O 45°
C. 60°
D. 30°

Answers

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.

The answer is 60 degrees I think!

A student in a chemistry lab has access to two acid solution .The first solution is 20% acid and the second is 45% acid .(the percentage are by volume). How many milliliters of each solution the student mix together to obtain 100 ml of a 30% acid solution?

Answers

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

Determine the best method to solve the system of equations. Then
solve the system. x - 3y = 25 and 2x + y = 64. can you please help!!!!!

Answers

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)

Si un empresario paga diariamente 50 a cada trabajador le faltaria 110 pero si les pagara 45 le sobraria 60 cuantos trabajadores tiene dicho empresario

Answers

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.

How many solutions does this equation have?

8z − 5 = 8z

Answers

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.

2 supplementary angles are in the ratio 6:3
Find the angles

Answers

120:60 i think that’s correct

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) :)
