First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533

Convert 3 hours to minutes = 3 x 60 = 180 minutes

The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas

Write a equation in standard form that contains a slope of 3 and contains (1,6)
jeka94

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

\bf (\stackrel{x_1}{1}~,~\stackrel{y_1}{6}) ~\hspace{10em} \stackrel{slope}{m}\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{6}=\stackrel{m}{3}(x-\stackrel{x_1}{1})\implies y - 6 = 3x-3 \\\\\\ y=3x+3\implies -3x+y=3\implies \stackrel{\textit{standard form}}{3x-y=-3}

What is the volume of this rectangular
Basile [38]
<h3>Given:</h3>
  • l= 5 m
  • b= 4 m
  • h= 3 m
<h3>Note that:</h3>
  • l= length
  • b= breadth
  • h= height
<h3>To find:</h3>

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

\large\boxed{Formula:V=\frac{1}{3}lbh}

First, multiply the length (5), breadth (4) and height (3).

5×4×3

= 60 \: cm

Now, divide 60 by 3.

\frac{60}{3}

\large\boxed{V= 20 \: {m}^{3}}

<u>Therefore, the volume of the given rectangular pyramid is 20 cubic meters.</u>
