In the area square is 64 centimeters what the length of one side

1 answer:

3 0

The length of one side is 8 centimeters.

Extra information:

When the area is square, it means that all sides are the same size. When the area of the square is 64 centimeters, it means that the length of one side is the opposite of square: square root. Therefore if you take the square root of 64, you end up with 8. You can check this, by "imagining" the length of the sides (8 centimeters) and calculate the area. This is done by multiplying the length by width. The length and width are both 8, so the area will be 64. Therefore the length is correct!

Surface = 2 x PI x r x H + 2 x PI x r^2

= 2 x r x h + 2 x r^2

= 2 x 6 x 12 + 2 x 6^2

= 144 + 72
= 216 PI in^2

Neptune has a mass of 1024 1032 milligrams. Use scientific notation to express the planet's mass in kilograms. 1

Levart [38]

Answer:

(b) The planet's mass =10.241032 kilograms.

Step-by-step explanation:

Here, the mass of Neptune = 1024 1032 milligrams

Also, given: 1 milligram = 0.0000001 kilograms.

or, 1 milligram = $1 \times 10^{(-6)}$ kilograms.

Now, to convert 1024 1032 milligrams in to kilograms, we get:

1024 1032 milligrams = $1024 1032 \times 10^{(-6)}$ kilograms.

Now solving $1024 1032 \times 10^{(-6)}$ , we get:

$1024 1032 \times 10^{(-6)} = 10.241032$ kilograms.

Hence the planet's mass =10.241032 kilograms.

The length of a line segment is 7. Its end points are (1, 3) and (k, 3). Solve for k. Is there more than one solution? Explain.

Brilliant_brown [7]

$Endpoints:\\\\A(1,3)\ and\ B(k,3)\\\\Formula\ for\ length\ of\ line:\\\\
|AB|=\sqrt{(x_b-x_a)^2+(y_b-y_a)^2}\\\\
|AB|=7\\\\7=\sqrt{(k-1)^2+(3-3)^2}\\\\
7=\sqrt{k^2-2k-1}\ \ |^2\\\\
49=k^2-2k-1
$ $49=k^2-2k-1\\\\
-k^2+2k+1+49=0\\\\
-k^2+2k+50=0\\\\ \Delta=b^2-4ac\\\\a=-1,\ b=2,\ c=50 \\\\\Delta=(2)^2-4*(-1)*50=4-=4+200=204\\\\ \sqrt{\Delta}=2\sqrt{51}$ $\\\\k_1=\frac{-b-\sqrt{\Delta}}{2a}\ \ k_1=\frac{-2-2\sqrt{51}}{2*(-1)}=1+\sqrt{51} \\\\\ or\ k_2=\frac{-b+\sqrt{\Delta}}{2a}\ \ k_1=\frac{-2+2\sqrt{51}}{2*(-1)}=1-\sqrt{51}$
