How many cubic feet are in 3 cubic yards

Mathematics

Mrrafil [7]4 years ago

1 yard contains 3 feet. Then to find how many cubic feet are in 1 cubic yard you raise both to the power 3. this is: 1 yard = 3 feet => (1 yard)^3 = (3 feet)3 => 1 yard^3 = 27 feet^3. Now you have to multiply by 3 to get the number of cubic feet in three cubic yards => 3 * (1 yard^3) = 3 (27 feet^3) => 3 yard^3 = 81 feet^3, then <span>there are 81 cubic feet in 3 cubic yards.</span>

k:\ y=m_1x+b_1\ \ \ \ and\ \ \ \ l:\ y=m_2x+b_2\\ \\the\ line\k\ is\ perpendicular\ to\ the\ line\ l\ \ \ \Leftrightarrow\ \ \ m_1\cdot m_2=-1\\----------------------------\\\\A.\\2y=-3x+5\ \ \Rightarrow\ \ \ y=-  \frac{3}{2}  x+2.5\ \ \Rightarrow\ \ m_1=- \frac{3}{2} \\\\2x+3y=4\ \ \Rightarrow\ \ 3y=-2x+4\ \ \Rightarrow\ \ y=- \frac{2}{3}x+1 \frac{1}{3}  \ \ \Rightarrow\ \ m_2=- \frac{2}{3} \\\\m_1\cdot m_2=- \frac{3}{2} \cdot (- \frac{2}{3})=1 \neq -1

B.\\5x-8y=9\ \ \Rightarrow\ \ -8y=-5x+9\ \ \Rightarrow\ \ \ y=  \frac{5}{8}  x-1 \frac{1}{8} \ \Rightarrow\ \ m_1= \frac{5}{8} \\\\12x-5y=7\ \Rightarrow\ \ -5y=-12x+7\ \ \Rightarrow\ \ y= \frac{12}{5}x-1 \frac{2}{5}  \ \ \Rightarrow\ \ m_2= \frac{12}{5} \\\\m_1\cdot m_2= \frac{5}{8} \cdot  \frac{12}{5}= \frac{3}{2}  \neq -1

A line contains (82,-96) and (87,-86) what is the slope of the line in simplified form
TiliK225 [7]

Here the change in x is +5 and that in y is +10 (from y= -96 to y= -86).  Thus, the slope, (change in y) / (change in x) is m = 10/5, or m = 2.
