At what position on the number line is the red dot located?

Naddik [55]

Answer:

D. $\sqrt{46}$

Step-by-step explanation:

Firstly, we know it's close to 6.75, so we can compute 6.75*6.75 and the product should be close to whatever's under the $\sqrt$ . 6.75*6.75 = 45.5625, so we can already answer.

We could also figure out why other answers are bad.

$\sqrt{92} > \sqrt{81} = 9\\\sqrt{56} > \sqrt{49} = 7\\\sqrt{36} = 6$

Solve using ARE= LENGTH X WIDTH.

Alexxandr [17]

X=lebgth
y=width.
I suggest this system of equations:
x=2y
(x+4)(y+4) - xy=88

we can solve this system by substitution method.
(2y+4)(y+4)-2y(y)=88
2y²+8y+4y+16-2y²=88
12y=88-16
12y=72
y=72/12
y=6

x=2y
x=2(6)=12

Answer: the dimensions of the original rectangle are:
length=12 m
width=6 m

Find the area of the shaded region.

Shtirlitz [24]

so, if you notice the inscribed regular pentagon, it "emits" 5 radii from the center of the circle, making 3 equal angles.

well, a circle has a total of 360°, so each angle must then be 360°/5, or 72°.

if we notice the line on the right-side, the diameter of the circle is 16 units, meaning its radius is 8 units.

so a shaded section is really just the area of a segment of a circle with an angle of 72° and a radius of 8, keeping in mind we have 3 segments there.

$\bf \textit{area of a segment of a circle}\\\\
A=\cfrac{r^2}{2}\left[ \cfrac{\pi \theta }{180}~~-~~sin(\theta ) \right]~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=8\\
\theta =72
\end{cases}
\\\\\\
A= \cfrac{8^2}{2}\left[ \cfrac{\pi(72) }{180}~~-~~sin(72^o ) \right]\implies A=32\left[ \cfrac{9\pi }{10}~~-~~ \stackrel{\approx}{0.95}\right]
\\\\\\
A\approx 9.7785774445044391446\qquad \qquad \stackrel{3~segments}{3A\approx 29.3357323335133174}$
