The change in the first round is -22.

The change in the second round is unknown, so we let x = the change in the second round.

When we add the two changes we get an overall change of 0.

-22 + x = 0

Add 22 to both sides of the equation.

x = 22

The change in the second round is 22 points because when you add 22 points to -22 points you get the overall change of 0 points.

A sector of a circle makes a 127° angle at its centre. If the arc of the sector has length 36 mm, find
Veseljchak [2.6K]

Answer:

Approximately 68.5\; \rm mm.

Step-by-step explanation:

Convert the angle of this sector to radians:

\begin{aligned}\theta &= 127^{\circ} \\ &= 127^{\circ} \times \frac{2\pi}{360^{\circ}} \\ &\approx 2.22\end{aligned}.

The formula s = r\, \theta relates the arc length s of a sector of angle \theta (in radians) to the radius r of this sector.

In this question, it is given that the arc length of this sector is s = 36\; \rm mm. It was found that \theta = 2.22 radians. Rearrange the equation s = r\, \theta to find the radius r of this sector:

\begin{aligned} r&= \frac{s}{\theta} \\ &\approx \frac{36\; \rm mm}{2.22} \\ &\approx 16.2\; \rm mm\end{aligned}.

The perimeter of this sector would be:

\begin{aligned}& 2\, r + s \\ =\; & 2 \times 16.2\; {\rm mm} + 36\; {\rm mm} \\ =\; & 68.5\; \rm mm\end{aligned}.

Evaluate x4 + 4x3 - 2x2 + 11x - 6 for x = 3
erica [24]

Step-by-step explanation:

f(x)  =  {x}^{4}  + 4 {x}^{3}  - 2 {x}^{2}  + 11x - 6

f(3) =  {3}^{4}  + 4. {3}^{3}  - 2. {3}^{2}  + 11.3 - 6

f(3) = 81 + 4.27 - 2.9 + 33 - 6

f(3) = 81 + 108 - 18 + 33 - 6

f(3) = 198

Jeremiah received $65 for his birthday and used part of it to buy 3 video games. The games cost the same amount, and he had $14
hram777 [196]

Jeremiah got $65 on birthday and spent some money on 3 video games and was left with $14.

He purchased 3 video games.

Let the cost one one video game be v.

The cost of each video game is same

So the cost of 3 video games is 3v.

Also he is left with $14 after paying for three games.

Hence

3v + 14 = 65

Subtracting 14 from both sides

3v + 14 -14 = 65-14

3v = 51

Dividing by 3 on both sides

v = 51/3

v = 17

Hence the cost of each video game is $17
