Answer:

804.4

Step-by-step explanation:

the formula for the volume of a cube is the side length cubed,

so:

(9.3)(9.3)(9.3) = 804.357

then round it to 804.4

hope this helped!

A) Pine Road and Oak Street form a right angle, so we can extract the relation

\tan30^\circ=\dfrac x{11\sqrt3}\implies\dfrac1{\sqrt3}=\dfrac x{11\sqrt3}\implies x=11

where x is the distance we want to find (bottom side of the rectangle).

Alternatively, we can use the other given angle by solving for x in

\tan60^\circ=\dfrac{11\sqrt3}x

but we'll find the same solution either way.

b) Pine Road and Oak Street form a right triangle, with Main Street as its hypotenuse. We can use the Pythagorean theorem to find how long it is.

(\text{Pine})^2+(\text{Oak})^2=(\text{Main})^2

Let y be the length of Main Street. Then

(11\sqrt3)^2+11^2=x^2\implies x^2=484\implies x=\pm22

but of course the distance has to be positive, so x=22.

The radius of the wheel of a bicycle is 14 inches. What is the distance that the bicycle covers after ten rotations? Use
ivolga24 [154]

Distance covered in 1 rotation = circumference of the wheel

                                                  = 2\pir

                                                  = 2 x \frac{22}{7} x 14

                                                  = 2 x 22 x 2

                                                  = 88 inches

Distance covered in 10 rotations = 88 x 10 = 880 inches

Therefore, the bike covers 880 inches after 10 rotations.

Divide -2x^3-5x^2+4x+2 by x+2
erik [133]

<u>Answer</u><u>: </u>

The correct option is C.  -2x^2-x+6, R(-10)

<u> Explanation: </u>

<u>Given:</u>

Dividend = -2x^3-5x^2+4x+2

Divider =(x+2)

<u>Solution</u>:

Now by using the division method , we will find out the quotient and remainder of the given equation  

And the equation will become  

-2x^3-5x^2+4x+2=(x+2)(-2x^2-x+6)-10

So , We will get the quotient =-2x^2-x+6

And Remainder = -10

Hence the Correct option which perfectly satisfy the given equation is C.
