Answer:

28 minutes

Step-by-step explanation:

4 miles = 45 minutes

4 kilometers = (m) minutes

45 ÷ 4= 11.25

4 kilos= 2.48548 miles

2.48548 x 11.25= 27.96165

m = 28 minutes

A diagram of Eric pool as shown below. He plans to fill this pool to a depth of 4ft with a garden hose that flows at 80ft expone

<span>The Volume of a Cylinder = </span><span>π <span>• r² • height<span>
</span></span></span>radius = 13.5 feet
volume = PI * 13.5^2 * 4 feet (the problem states it is to be filled to a depth of 4 feet)
volume = PI * 182.25 * 4
volume = <span> <span> <span> 2,290 cubic feet</span></span></span>
The hose delivers 80 <span>cubic feet per hour so it will take:

The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2,

timama [110]

N = d - 5

2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3

Let's see if it checks out.
n = 3
d = 8

2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.

En una escuela hay 135 mujeres y la razón entre hombres y mujeres es de 7 a 9. ¿Cuántos estudiantes hay en la escuela? *

Answer:

There are 531.5625 students which is 531 students in the school

Step-by-step explanation:

We add the ratio numbers ( 7 + 9 = 16)

We then divide that number by 135 ( 135 / 16 = 8.4375)

After we multiply by each ratio number, ( 7 and 9).

And we end up with 531.5625, also 531 students.

--------------------------------------------------------------------------------

Hay 531.5625 estudiantes, que son 531 estudiantes en la escuela.

Explicación paso a paso:

Sumamos los números de razón (7 + 9 = 16)

Luego dividimos ese número por 135 (135/16 = 8.4375)

Después, multiplicamos por cada número de razón (7 y 9).

Y terminamos con 531.5625, también 531 estudiantes.
