Answer:

4.05 meters or 405 cm

Step-by-step explanation:

The equation to use is

(x - 330) x 5 = x - 30

330 is equal to 3.30 meters.

Then solve the equation.

(X - 330) x 5 = x - 30

5x - 1650 = x - 30

-x

4x - 1650 = -30

+1650 + 1650

4x = 1620

/4 /4

X = 405cm

The width of a rectangular prism is six times its length. The height is five times its length. If its length is m units, what is
I am Lyosha [343]

Answer:

30m^3 cubic units.

Step-by-step explanation:

Let m represent length of the rectangular prism.

We have been given that the width of a rectangular prism is six times its length, so width of the prism would be 6m.

We are also told that the height is five times its length, so height of the prism would be 5m.

We know that volume of rectangular prism is height times width times length.

\text{Volume of rectangular prism}=lwh

\text{Volume of rectangular prism}=m\cdot 6m\cdot 5m

\text{Volume of rectangular prism}=30m^3

Therefore, the volume of the given rectangular prism would be 30m^3 cubic units.

A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal?
aliina [53]

Answer:

41 units

Step-by-step explanation:

Rectangles have right angles, so we can use Pythagorean theorem to find the diagonal.

c² = a² + b²

c² = 9² + 40²

c² = 81 + 1600

c² = 1681

c = 41

Slope is -4 and (1,6) is on the line, in standard form
Finger [1]

Answer:

4x + y = 10

Step-by-step explanation:

The point-slope form of the equation of a straight line is y - k = m(x - h).

Letting m = -4, 1 = h and 6 = k, we get                               y - 6 = -4(x - 1).

Now we must rewrite this in standard form.  Do this:  Carry out the multiplication.  We get y - 6 = -4x + 4.

Now add 6 to both sides, obtaining

                                         y = -4x +10

Finally, add 4x to both sides, obtaining:

                                          4x + y = 10.  This is the desired equation in standard form.
