Answer:

≈ 13.1 cm²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{60}{360}

   = π × 5² × \frac{1}{6}

   = 25π ÷ 6

   ≈ 13.1 cm² ( to 1 dec. place )

Answer:

area = 13.1 cm²

Step-by-step explanation:

area of sector formulae:

\frac{theta}{360}  \times \pi {r}^{2}

theta = 60°

radius = 5 cm

π = 22/7

substitute the values into the formulae

\frac{60}{360}  \times  \frac{22}{7}  \times  {5}^{2}

\frac{1}{6}  \times  \frac{22}{7}  \times   25

\frac{1}{6}  \times  \frac{25 \times 22}{7}

\frac{1}{6}  \times  \frac{550}{7}

\frac{550 \times 1}{6 \times 7}

\frac{550}{42}

13.1 \: cm {}^{2}

Solve the system substitution y= 4x + 1 and 3x+2y =13
strojnjashka [21]

Given :

{\qquad \sf \dashrightarrow  y= 4x + 1 \: –––– \sf \:  (i)}

{\qquad \sf \dashrightarrow   3x + 2y = 13 \: –––– \sf \:  (ii)}

Now, Substituing the value of y in equation (ii) :

{\qquad \sf \dashrightarrow   \: 3x + 2y = 13   }

{\qquad \sf \dashrightarrow   \: 3x + 2(4x + 1) = 13   }

{\qquad \sf \dashrightarrow   \: 3x + 8x + 2 = 13   }

{\qquad \sf \dashrightarrow   \: 11x + 2 = 13   }

{\qquad \sf \dashrightarrow   \: 11x  = 13 - 2   }

{\qquad \sf \dashrightarrow   \: 11x  = 11   }

{\qquad \sf \dashrightarrow   \: x  =  \dfrac{11}{11}    }

{\qquad \sf \dashrightarrow   \bf \: x  = 1   }

Now, substituting the value of x in equation (i) :

{\qquad \sf \dashrightarrow  y= 4x + 1}

{\qquad \sf \dashrightarrow  y= 4(1) + 1}

{\qquad \sf \dashrightarrow  y= 4 + 1}

{\qquad \bf \dashrightarrow  y= 5}

Answer: 6




Step-byStep:


[(18- 8) x 3) + (4+3) x 6] divided by 12

step 1- start with the stuff in the parentheses

[(10 x 3) + (7 x 6)] divided by 12

step 2- simplify things in parentheses

[30 + 42] divided by 12

step 3- simplify even more

[72] divided by 12

step 4- remove brackets, and simply even further

72 divided by 12 = 6



Hope this helps

Elis [28]

Answer:

x = 36

Step-by-step explanation:

x - 12\sqrt{x} + 36 = 0

Subtract x and 36 from both sides.

-12\sqrt{x} = -x - 36

Divide both sides by -1.

12\sqrt{x} = x + 36

Square both sides.

144x = x^2 + 72x + 1296

Subtract 144x from both sides.

0 = x^2 - 72x + 1296

Factor the right side.

0 = (x - 36)^2

x - 36 = 0

x = 36

Since the solution of the equation involved squaring both sides, we musty check the answer for possible extraneous solutions.

Check x = 36:

x - 12\sqrt{x} + 36 = 0

36 - 12\sqrt{36} + 36 = 0

36 - 12\times 6 + 36 = 0

36 - 72 + 36 = 0

0 = 0

Since 0 = 0 is a true statement, the solution x = 36 is a valid solution.
