Answer:

9 bags

Step-by-step explanation:

We need to find the area of the putting green with a radius of 30 ft

A = pi r^2

A = 3.14 (30)^2

A =2826 ft^2

Each bag will cover 315 ft^2

Divide the area by 315 ft^2 to determine the number of bags

2826/315 =8.971428571 bags

Rounding up to the nearest bag

9 bags

The water in a reservoir decreased by 47% during a drought. Before the drought, the reservoir held 44,580 acre ft (AF) of water.
RSB [31]


44,580 x 47 %

44,580 x .47 = 20,952.6

So, the water decreased 20,952.6 ft

If you want the water level after the drought just subtract.

44,580 - 20,952.6 =  23,627.4 ft

Hope this helps. :)

How to convert 11/27 into a decimal
il63 [147K]

Answer:

11 ÷ 27 = 0.407407

Step-by-step explanation:

Una fracción, como 11/27, tiene un numerador y un denominador separado por una línea divisoria.

11 es el numerador, porque es el número de arriba de la línea divisoria.

27 es el denominador porque es el número de abajo de la línea divisoria.

Para convertir 11/27 a decimal, divide el numerador por el denominador.

A monomial of the 2nd degree with a leading coefficient of 3
Rzqust [24]

Given:

Polynomials

To find:

Monomial of 2nd degree with leading coefficient 3

Solution:

Monomial is an algebraic expression with only one term.

Option A: 3 n^{2}-1

It is not a monomial because it have 2 terms.

It is not true.

Option B: 3 n-n^{2}

It is not a monomial because it have 2 terms.

It is not true.

Option C: 3 n^{2}

It have one term only. So, it is a monomial.

Degree means highest power. So degree = 2

Leading coefficient means the value before variable.

Leading coefficient = 3

It is true.

Option D: 2n^3

It have one term only. So, it is a monomial.

Degree means highest power. So degree = 3

It is not true.

Therefore 3 n^{2} is a monomial of 2nd degree with a leading coefficient of 3.
