A.) 75
B.) 115
C.) 10
D.) 65

Answers

Answer:

D) 65

Step-by-step explanation:

<1 = 11x + 5

<2 = 8x - 15

These angles are supplementary so,

11x + 5 + 8x - 15 = 180

19x - 10 = 180

19x = 190

x = 10

Lukas depositó $ 3000 en una cuenta de ahorros que genera una tasa de interés del 3.7% compuesto anualmente. ¿Cuál es el valor total de la cuenta después de 5 años?

Answers

Answer:

El valor total de la cuenta después de 5 años es de $3,598.

Step-by-step explanation:

Para encontrar la respuesta, tienes que utilizar la fórmula para encontrar el valor futuro:

VF=VP*(1+i)^n

VF=valor futuro

VP= valor presente=$3000

i=tasa de interés=0.037

n=número de periodos de tiempo=5 años

Ahora, puedes reemplazar los valores en la fórmula:

VF=3,000*(1+0.037)^5

VF=3,000*(1.037)^5

VF=3,598

De acuerdo a esto, la respuesta es que el valor total de la cuenta después de 5 años es de $3,598.

A staircase has a height of 14ft and a slant length of 52ft.

Answers

Answer:

50.1ft approx

Step-by-step explanation:

Given data

Height=14ft

Slant height= 52ft

Applying Pythagoras theorem, we can solve for the horizontal lenght

we know that

hyp^2= Opp^2+Adj^2---------- Pythagoras theorem

52^2=14^2+x^2

2704=196+x^2

2704-196=x^2

2508=x^2

x= √2508

x=50.07

Hence the horizontal distance is 50.1ft approx

Find the circumference of the semi circle 7cm

Answers

Given:

A semicircle with radius 7 cm.

To find:

The circumference of the given semi circle.

Solution:

We know that,

Circumference of a semi circle = Half of circumference of the circle + Diameter

                                                    [tex]=\dfrac{1}{2}(2\pi r+d[/tex]

                                                    [tex]=\pi r+2r[/tex]

Putting [tex]\pi=\dfrac{22}{7},r=7[/tex], we get

Circumference of the semi circle [tex]=\dfrac{22}{7}(7)+2(7)[/tex]

                                                        [tex]=22+14[/tex]

                                                        [tex]=36[/tex]

Therefore, the circumference of the given semi circle 36 cm.

Answers

Answer:

y = 10 - 0.3t

Step-by-step explanation:

Amount of cat food purchased= 10 pounds

Daily pounds fed to dog = 0.3 pounds

How the amount of cat food in bag changes over time ;

Let y = amount of cat food left in bag
