Answer:

Step-by-step explanation:

A circle centered in $P(x_o,y_o)$ an radius $r$ has a equation:

$(x-x_o)^2+(y-y_o)^2=r^2$

So, your equation wold be:

$(x-0)^2+(y-0)^2=8^2\Rightarrow x^2+y^2=64$

Dion puts seven tenths of his allowance into savings each month what fraction of his saving doesnt go in

S_A_V [24]

Answer:

$\frac{3}{10}$ of his allowance doesn’t go into Dion’s savings.

Step-by-step explanation:

We know that $\frac{7}{10}$ of Dion’s savings is going into his savings.

Since the denominator is “10” we know that $\frac{10}{10}$ is the fraction that represents all of his allowance money.

So, we would subtract $\frac{7}{10}$ from $\frac{10}{10}$ .

$\frac{10}{10}$ - $\frac{7}{10}$ = $\frac{3}{10}$

A cuboid has a square base.

padilas [110]

The length of one side of the square base is 8.5 centimeters.

<u>Given the following data:</u>

Volume of cuboid = 867 cm

Height = 12 cm

To find the length of one side of the square base:

Mathematically, the volume of a cuboid is given by the formula:

$Volume = Base \; area$ × $Height$

Substituting the given values, we have:

$867 = Base \; area$ × $12$

$Base\;area = \frac{867}{12}$

Base area = 72.225 $cm^2$

Now, we can find the length by using the formula:

$Area \;of\;a \;square = length^2$

$72.25 = length^2$

$Length = \sqrt{72.25}$

<em>Length</em><em> = </em><em>8.5 centimeters</em>.

Therefore, the length of one side of the square base is 8.5 centimeters.

Which is a right triangle formed using a diagonal through the interior of the cube? A cube. The top face has points G, B, C, F a

Black_prince [1.1K]

Answer: The correct option is triangle GDC

Step-by-step explanation: Please refer to the picture attached for further details.

The dimensions give for the cube are such that the top surface has vertices GBCF while the bottom surface has vertices HADE.

A right angle can be formed in quite a number of ways since the cube has right angles on all six surfaces. However the question states that the diagonal that forms the right angle runs "through the interior."

Therefore option 1 is not correct since the diagonal formed in triangle BDH passes through two surfaces. Triangle DCB is also formed with its diagonal passing only along one of the surfaces. Triangle GHE is also formed with its diagonal running through one of the surfaces.

However, triangle GDC is formed with its diagonal passing through the interior as shown by the "zigzag" line from point G to point D. And then you have another line running from vertex D to vertex C.
