how many pounds of rock will you need to fill an area 25 ft by 35 ft to a depth of 2 in. If the rock weighs 1050 lb cubic yard?
Eduardwww [97]

The volume of the area is Length x width x height:

25 x 35 x 2/12 = 145.83 cubic feet.

1 cubic foot = 0.037 cubic yards:

145.83 x 0.037 = 5.40 cubic yards.

5.4 cubic yards x 1050 lbs/ cubic yard = 5,665.6 pounds.

Note:

Rounding and conversion may change the answer slightly, but I believe I rounded everything as it should be.

Write the equation for (-8, -8), with a slope if three
valentina_108 [34]

Answer:

Part--1:

We know that a equation in point-slope form is represented by:

<em> y-y1=m</em>

<em />

where m is the slope of the line and  is a point through which the line passes.  

<em />

<em>               </em>

<em />

 Consider a equation in a point-slope form as:

         

This means that the slope of the line is: 5

and the line  passes through the point (1,5).

Part--2:

Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m

Since,

Let this perpendicular line passes through (2,6)

Hence, the equation of a line in point slope form is given by:

Please help me with this question!
mixer [17]

Hi! I'm happy to help!

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:

18×8=

Now all we have to do is multiply:

18×8=

144

He can make 144 croissants!

I hope this was helpful, keep learning! :D
