¿Cuáles son las longitudes de un terreno rectangular, si se sabe que el ancho es dos veces más pequeño que el largo, y que su área es de 16, 200 m2? cuanto mide el ancho cuanto mide el largo

Answers

Answer:

El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m

Step-by-step explanation:

Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.

En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.

Siendo el área del terreno rectangular 16,200 m², entonces

x*(x÷2)= 16,200 m²

Resolviendo:

x² ÷2= 16,200 m²

x²= 16,200*2 m²

x²= 32,400 m²

x= √32.400 m²

x= 180 m

Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

Find the value of each variable in the parallelogram?

Answers

Answer:

Step-by-step explanation:

In parallelogram opposite angles are equal

6x = 66      {Divide both sides by 6}

x = 66/6

x = 11

20y - 46 = 13y + 10     {Add 46 to both sides}

20y - 46 + 46 = 13y + 10 + 46

             20y   = 13y + 56     {Subtract 13y from both sides}

   20y - 13y    = 13y-13y + 56

              7y    =  56    {Divide both sides by 7}

                y =  56/7

y = 8

Step-by-step explanation:

3 is the slope. Since it is y/x, then it is 9/3, which is simplified to 3/1.

Answer: 3

Why?
You need two points to find slope I will use 5,19 and 2,10.
Slope is the difference of Y over the difference of x
19-10/5-2= 9/3 (simplify but divided each by 3)
3/1 so the slope is 3

You plan to go snowboarding this weekend in Pennsylvania. The resort charges $15.75 per hour in addition to a $25 deposit to rent a snowboard. Write and solve a linear equation to find the total cost to rent the snowboard from 8:30 a.m. to 12:30 p.m.

Answers

Answer:

$88 in total

Step-by-step explanation:

x = number of hours

y = total cost to rent the snowboard.

$25 is already guaranteed

25 + 15.75x = y

since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.

25+15.75(4) = y

88 = y

Triangles MNQ and MOP are similar. What is the slope of segment MO?

A. 1/3
B. 1/2
C. 2/3
D. 3/2

Answers

Answer:

D. 3/2

Step-by-step explanation:

The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

If Tim plotted the points 2,4 and 6,4 What is the equation of a line that passes both of tim’s points ?

Answers

Answer:

y = 4

Step-by-step explanation:

1. Find the slope

slope = rise over run or change in y divided by change in x

The slope of (2,4) and (6,4) is

(4 - 4)/(6 - 2) = 0/4 = 0

the slope is 0

2. Use point-slope form: y - y₁ = m(x - x₁)

(2, 4) -> x = 2 y = 4

m -> (slope) = 0

y - 4 = 0(x - 2)

y - 4 = 0

y = 4

A quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years. What is the value of the quantity after 0.7 decades, to the nearest hundredth?

Answers

Answer:3329.95

Step-by-step explanation:

The value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.

Given that, a quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years.

What is the exponential function?

Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

We know that, S.I=(P×T×R)/100

Amount after 4 years is 1980

So, 990= (990×4×R)/100

⇒ 39.6R=990

⇒ R=990/39.6

⇒ R=25%

Amount = [tex]a(1+r)^t[/tex]

= [tex]990(1+0.25)^{0.7}[/tex]

= 1157.37

Therefore, the value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.

Answer:

(4, 6 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 36 → (1)

y = - [tex]\frac{1}{2}[/tex] x + 8 → (2)

Substitute y = - [tex]\frac{1}{2}[/tex] x + 8 into (2)

3x + 4(- [tex]\frac{1}{2}[/tex] x + 8) = 36 ← distribute and simplify left side

3x - 2x + 32 = 36

x + 32 = 36 ( subtract 32 from both sides )

x = 4

Substitute x = 4 into (2) for corresponding value of y

y = - [tex]\frac{1}{2}[/tex] × 4 + 8 = - 2 + 8 = 6

solution is (4, 6 )

What is the measure of the vertex angle

Answers

Answer:

Vertex angle = 124°

Step-by-step explanation:

m<BAC = m<BCA (base angles of isosceles ∆ are congruent)

7x + 1 = 5x + 9

Collect like terms

7x - 5x = -1 + 9

2x = 8

divide both sides by 2

x = 4

Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)

Plug in the value of x

Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))

Vertex angle = 180 - (29 + 29)

Vertex angle = 124°
