Answer:

1000

Step-by-step explanation:

area of rectangle = width x length

Given:

  • width of floor = 40 m
  • length of floor = 50 m

⇒ area of floor = 40 x 50 = 2000 m²

Given:

  • width of tile = 1 m
  • length of tile = 2 m

⇒ area of tile = 1 x 2 = 2 m²

Number of tiles needed = area of floor ÷ area of one tile

                                       = 2000 ÷ 2

                                       = 1000

Answer:

1000 tiles needed.

area of floor:

  • length * width
  • 50 * 40
  • 2000 m²

area of each tile:

  • length * width
  • 1 * 2
  • 2 m²

<u>solve</u>:

\sf total  \ number  \ of   \ tiles  \ needed =  \dfrac{area \  of \ floor}{area \  of \  each \ tile}

\sf total  \ number  \ of   \ tiles  \ needed =  \dfrac{2000}2}

\sf total  \ number  \ of   \ tiles  \ needed =  1000

Ben jogged 4 and 1/2 miles in 1 and 1/4 hours at a constant rate. How far did Ben jog in one hour? *
Mrac [35]

let's firstly convert the mixed fractions to improper fractions and then proceed.

\stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}}~\hfill \stackrel{mixed}{1\frac{1}{4}}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}} \\\\[-0.35em] ~\dotfill

\begin{array}{ccll} miles&hours\\ \cline{1-2} \frac{9}{2}&\frac{5}{4}\\[1em] x&1 \end{array}\implies \cfrac{~~ \frac{9}{2}~~}{x}=\cfrac{~~ \frac{5}{4}~~}{1}\implies \cfrac{~~ \frac{9}{2}~~}{\frac{x}{1}}=\cfrac{5}{4}\implies \cfrac{9}{2}\cdot \cfrac{1}{x}=\cfrac{5}{4} \\\\\\ \cfrac{9}{2x}=\cfrac{5}{4}\implies 36=10x\implies \cfrac{36}{10}=x\implies \cfrac{18}{5}=x\implies 3\frac{3}{5}=x
