0.8m=32. Please help, find what m = and please show the steps

meriva

M = 32/0.8 m = 320/8 m = 40 Rule: You see in my second step? You have to get rid of the decimal to make it a whole number. So keep on adding 0 to the 32 until you transform 0.8 to a whole number. Ionly added 0 once to 32 because I only have to move the decimal once to make 0.8 a whole number. Hi

How do i simplify 1/3√45 using product property

TEA [102]

$\frac{1}{3\sqrt{45}}$ = $\frac{1}{3\sqrt{3 x 3 x 5}} = \frac{1}{9\sqrt{5}}$ x $\frac{\sqrt{5}}{\sqrt{5}}$ = $\frac{\sqrt{5}}{9 x 5}$ = $\frac{\sqrt{5}}{45}$

Solve for k. 9/2k-3=4/k+1

Ivenika [448]

You'll need to use parentheses here to convey this problem accurately to possible helpers. Unsure of whether you mean (9/2)k -3 or 9 / (2k-3).

I will assume that you mean:

9 4
------- = ---------
2k-3 k+1

Cross mult: 9k+9=8k-12, so k= -21.

If that's not what you expected, then try again to present the problem without ambiguities.

A rectangle has vertices at these coordinates. (5, −3), (5, −8),(8, −3) What are the coordinates of the fourth vertex of the rec

Katen [24]

Answer:

Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).

Step-by-step explanation:

Given Vertices of Rectangle are ( 5 , -3 ) , ( 5 , -8 ) , ( 8 , -3 )

To find: Coordinate of Fourth Vertex of the rectangle.

First, Plot all given three points on the graph.

Graph is attached.

We know that Opposite sides of the rectangle are equal and parallel.

Also All angles of rectangles are right angle.

So to satisfy these properties of rectangle.

4th coordinate must be on line x = 8 and y = -8.

⇒ Fourth coordinate = ( 8 , -8 )

Therefore, Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).
