Is a rectangular prism has a length width and height of 3/8cm, 5/8cm and 7/8 in a meter respectively then the volume of the pris
myrzilka [38]

The volume of a rectangular prism is given by the multiplication of its three dimensions: if w, h, l are the width, height and length of the prism, the volume is

V = w\cdot h\cdot l

So, in your case, you have

V = \dfrac{3}{8} \cdot \dfrac{5}{8} \cdot \dfrac{7}{8} = \dfrac{3\cdot 5 \cdot 7}{8\cdot 8 \cdot 8} = \dfrac{105}{512}

Since the -13 has the absolute value signs next to it, the 13 becomes a positive, but there is a negative outside the absolute value, and the negative sign and the absolute value sign cancelled previously, so the expressions is now
-13
The absolute value signs cancel out a negative only inside the signs, not outside, so the negative sign in the outside keeps.

Step-by-step explanation:

Answer A: Subtract 9 from both sides

4b.) Write an equation using point-slope form with a slope of 2.3 and goes
Yuri [45]

Answer:

y+3.2=2.3(x-4.5)

Step-by-step explanation:

So the point-slope formula looks like this: y-y_1=m(x-x_1)

y_1 = any y point on the line

x_1 = any x point on the line

m = the slope

And hey, look, we're already given all that information!

So we can just plug those values into the equation:

y+3.2=2.3(x-4.5)

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)
