Step-by-step explanation:

5^2-3^2=16

sqrt16=4

Answer:

A. 4

Step-by-step explanation:

hypotenuse (h) = 5

base (b) = 3

perpendicular (p) = a = ?

We know

By using Pythagoras theorem

p = √( h² - b²)

a = √( 5² - 3²)

a = √(25 - 9)

a = √ 16

a = 4

Answer:

El precio de la entrada al cine es de $56

Step-by-step explanation:

Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28  ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:

                                                 28 x 2 =$56

El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.

Entonces podemos hacer la siguiente relación matemática: Precio total de las palomitas dos veces por semana = Precio de la entrada a cine.

Answer:

13,200 vehicles

Step-by-step explanation:

57% of 80,000 is 45,600

3 people per car for 2000 vehicles is 6,000

45,600-6,000=39,600

lastly 39,600/3=13,200

Answer:

Answer:

The answer is 0.60 cents

Step-by-step explanation:

1.20 ÷ 2 = .60

.60 × 2 = 1.20

.60 × 4 = 2.40

.60 × 7 = 4.20

.60 × 12 = 7.20

Answer:

V = 288π [tex]unit^{3}[/tex]

Step-by-step explanation:

The volume of the sphere = [tex]\frac{4}{3}[/tex] * π * [tex]r^{3}[/tex]

V =  [tex]\frac{4}{3}[/tex] * π *[tex]6^{3}[/tex]

V = 288π [tex]unit^{3}[/tex]

(π is pi or 3.14)

Answer:

$19.10

Step-by-step explanation:

So since he charges $1.85 for the first quarter mile we can keep that as it is for now. If we add 0.25 4 times to make it $1 that would be a mile. We just have to add $17.25 plus the original $1.85 fee

Answer:

about $1

Step-by-step explanation:

Answer:

an = 6n - 18

Step-by-step explanation:

a3 = 0, a4 = 6, a5 = 12, a6 = 18, a7 = 24

a3 = a + 2d

a4 = a + 3d

a + 2d = 0 (1)

a + 3d = 6 (2)

Subtract (1) from (2) to eliminate a

3d - 2d = 6 - 0

d = 6

Substitute d = 6 into (1)

a + 2d = 0 (1)

a + 2(6) = 0

a + 12 = 0

a = -12

nth term,an = a + (n - 1)d

= -12 + (n - 1) 6

= -12 + 6n - 6

= 6n - 18

an = 6n - 18

Answer:

Approximately 40.37 feet

Step-by-step explanation:

Opposite = 30 feet and the length of the wire (I'll use x to represent it) is the hypotenuse.

sin(48) = 30/x

x = 30/sin(48)

x = 30/0.74

x ≈ 40.37

Answer:

No, they aren't equal

Step-by-step explanation:

5x & 5+x

let's say x=1

5(1)=5

but 5+(1)=6

Therefore they aren't equal

Answer:

See explanation below

Step-by-step explanation:

Find the value of x in each of the following

1) x-1+5√x-1+3=0

5√x-1 = -x -2

Square both sides

25(x-1) = (-x-2)^2

25(x-1) = x^2+4x + 4

25x-25 = x^2+4x + 4

x^2 +4x + 4 - 25x + 25 = 0

x^2 - 21x + 29 = 0

x = 21±√21²-4(29)/2

x = 21±√441-116/2

x = 21±√325/2

x = 21±18.03/2

x = 21+18.03/2 and 21-18.03/2

x = 19.515 and 1.485

4)  x^4-64=0

x^4 = 64

[tex]x = \sqrt[4]{64}[/tex]

x = 2.83

Answer:

Fairview is lower.

Step-by-step explanation:

IXL

The required, city Fairview has a lower ratio of negative to positive reviews.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
A restaurant critic reviewed restaurants in Oxford and Fairview.
In Oxford, the critic gave 18 negative reviews and 33 positive reviews.
ratio = 18 / 33 = 0.54

In Fairview, 5 of the reviews were negative and 11 were positive reviews.
Ratio = 5 / 11 = 0.45

Thus, the required, the city of Fairview has a lower ratio of negative to positive reviews.
