A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.
Triss [41]

Answer:

650 kg/m³

Step-by-step explanation:

The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.

 density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³

 = 650 kg/m³

Hope this answer helps you :)

Have a great day

Write an equation in slope intercept form for the line that passes thru the points (4,-2) and (-5,7)
shepuryov [24]

Answer:

y = -x + 2

Step-by-step explanation:

The equation of a line in a slope intercept form is given as :

y = mx + c, where m is the gradient and c, y - intercept.

First, let us find the gradient, m of the line that passes through the points, (4,-2) and (-5,7) using the relation ;

m = \frac{y_2 - y_1}{x_2- x_1}

By substitution we get

m = \frac{7- (- 2)}{ - 5 - 4}

\implies m = \frac{7 + 2}{ - (5 + 4)}

\implies m = \frac{9}{ - 9} =  - 1

We substitute any of the points and the value of m into y= mx + c to find the value for c.

\implies  - 2 = 4( - 1) + c

\implies  - 2 =  - 4+ c

Adding 4 to both sides.

\implies  4- 2=  - 4 + 4+ c

\implies  4- 2= + c

\implies  c = 2

Hence the equation of the line is :

y = -x +2
