Answer:

12 1/2 mins

Step-by-step explanation:

If the teacher has 47 1/2 minutes left, and there are 60 minutes in an hour, all you have to do is 60-47.5 which is 12.5. To change this into a mixed number, we know 5 is half of 10, so it is 12 1/2 minutes. Hope this helped.

<h2>60-47 1/2</h2><h2>60-47.5=12.5</h2><h2>12.5= 12 1/2</h2>

Answer:

95 over 2

because if it is 47 you double that since the denominator is 2 then you add the numerator and now you have your answer.

F (x)= 5x-14 G (x)= 12x+8 H (x)= 62x-54 Dadas las funciones resolver las siguientes operaciones a. F (x)+ G (x) b. G (x)- (H (x)
Alborosie

Answer:

a) 17\cdot x -6, b) -45\cdot x +48, c) 518\cdot x^{2} +1306\cdot x -1012, d) \frac{-57\cdot x +40}{17\cdot x -6}, e) 2\cdot \left(\frac{3\cdot x + 2}{31\cdot x - 27} \right)

Step-by-step explanation:

Sean f(x) = 5\cdot x -14, g(x) = 12\cdot x + 8 y h(x) = 62\cdot x - 54. A continuación, desarrollamos las siguientes operaciones:

a) f(x) + g(x)

(5\cdot x - 14) + (12\cdot x + 8)

17\cdot x -6

b) g(x) - [h(x)-f(x)]

(12\cdot x + 8) - [(62\cdot x - 54)-(5\cdot x - 14)]

12\cdot x + 8 - (57\cdot x -40)

12\cdot x +8 -57\cdot x +40

-45\cdot x +48

c) [g(x)-f(x)]\cdot [h(x)+g(x)]

[(12\cdot x + 8)-(5\cdot x -14)]\cdot [(62\cdot x -54)+(12\cdot x +8)]

(12\cdot x +8 -5\cdot x +14) \cdot (62\cdot x -54+12\cdot x+8)

(7\cdot x +22)\cdot (74\cdot x-46)

7\cdot x \cdot (74\cdot x - 46)+22\cdot (74\cdot x -46)

(7\cdot x)\cdot (74\cdot x) - 46\cdot (7\cdot x )+22\cdot (74\cdot x)-22\cdot (46)

518\cdot x^{2}-322\cdot x +1628\cdot x -1012

518\cdot x^{2} +1306\cdot x -1012

d) \frac{f(x)-h(x)}{g(x) + f(x) }

\frac{(5\cdot x - 14)-(62\cdot x - 54)}{(12\cdot x +8)+(5\cdot x -14)}

\frac{-57\cdot x +40}{17\cdot x -6}

e) \frac{g(x)}{h(x)}

\frac{12\cdot x + 8}{62\cdot x - 54}

\frac{4\cdot (3\cdot x +2)}{2\cdot (31\cdot x -27)}

2\cdot \left(\frac{3\cdot x + 2}{31\cdot x - 27} \right)

Can someone please explain what I need to do pls asap
alexgriva [62]

Answer: 1) 530.66 ft^2

Step-by-step explanation:

You need to find the area of the circles.

They gave you the formula to find them which is

Area = Pi * R^2    //// Pi times Radius squared will give you the area.

For example, the radius of the 1st question is 13ft. We use it with the formula given.

A = 3.14 * 13^2  /// 13 squared is just 13 x 13 = 169

A = 3.14 * 169   /// Now multiply Pi times 169

A = 530.66      /// Thats your answer.

530.66 ft^2
